Nuclear materials detection technology wins national award

In the United States, tens of thousands of cargo containers – most the size of a railcar – enter the country every day through one of 93 maritime ports. Each container holds a surplus of products ranging from clothing to plasma televisions to medical equipment bound for places such as superstores and hospitals.

But since Sept. 11, 2001, concerns have been raised about how best to prevent dangerous materials or contraband items from being smuggled into the country alongside the millions of imported goods. In particular, homeland security and law enforcement professionals are most concerned about the potential for illicit radiological materials to make their way into the country through shipping ports.

The traditional counterproliferation approach has been to develop and implement a massive cargo screening program with the lofty goal of inspecting every cargo container being off-loaded on the dock. But this approach has been problematic, mainly due to the limited technical advances in screening technology and the time it takes to scan each container.

In addition, new concerns about the worldwide availability of nuclear materials and technology, combined with a rise in global terrorist operations, have likely increased the risk of a domestic nuclear attack. Nonproliferation experts claim a greater emphasis is needed on detecting nuclear materials before they enter or come near the 95,000-mile maritime border of the United States.

INL's Solution

To address this growing challenge, scientists and engineers at the U.S. Department of Energy's Idaho National Laboratory have developed an award-winning prototype technology capable of accurately scanning cargo containers for smuggled and shielded nuclear materials at long distances.

The technology, developed by INL scientist Dr. James Jones and a team of INL and Idaho Accelerator Center engineers, is known as the Photonuclear Inspection and Threat Assessment System, or PITAS.

The system uses many of the same commercial components found in modern cancer treatment devices, including a linear accelerator that creates an invisible high-energy photon beam, which interrogates and identifies suspected nuclear materials. The beam works by inducing fission reactions in nuclear materials that create an assortment of prompt and delayed neutron and gamma rays. The delayed rays are analyzed by a series of detectors that looks for peaks and signatures consistent with illicit nuclear materials.

With PITAS in operation, security officials have the ability to scan cargo containers and detect dangerous nuclear materials while ships are still at sea.

And since the PITAS technology was designed to detect and alert operators to nuclear materials that have been covertly shielded, radiological dangers such as plutonium, uranium or thorium are distinguished during detection from simple medical or household items that often contain trace radioactive elements.

This added capability reduces common false positives and performs cargo scanning more efficiently. In addition, the technology was built to complete this entire process in several minutes and leave no residual environmental impact.

Award-Winning Technology

This week, the Christopher Columbus Fellowship Foundation awarded its 2008 Homeland Security Award to recognize the PITAS technology for its numerous enhancements and advantages over current screening technology.

The Foundation and its co-sponsor, AgustaWestland North America, annually award one scientist a $25,000 prize for development of technology that has the potential to solve a complex national security challenge.

in announcing the recognition, Kimberly Owens, chair of the foundation, said, "Thousands of tons of cargo move through U.S. ports daily with little or no inspection. The Christopher Columbus Foundation and AgustaWestland are pleased to recognize Dr. Jones and his team for their work on the development of a nuclear materials detection system to facilitate the inspection of cargo containers for illicit nuclear material."

The Christopher Columbus Fellowship Foundation is an independent federal agency established by Congress in 1992 to encourage and support the development of technology that benefits mankind. The foundation's board and members of the award selection committee are presidential appointees. AugustaWestland North America, Inc. is one of the nation's largest manufacturers of law enforcement and military helicopters.

"As a lifelong scientist and inventor, I have been very fortunate to have worked on technology like the PITAS system that has the potential to save lives and combat terrorism," said Jones. "This is something that the Christopher Columbus Fellowship Foundation and AgustaWestland North America has recognized, and I am honored to accept this award."

In September, the PITAS technology was field tested in a realistic environment for its accuracy, range, and detection time. While the results are still being analyzed, one thing is certain, the PITAS technology represents a breakthrough homeland security solution.

The award's ceremony will take place the evening of Thursday, Sept. 11, in the U.S. Capitol Building.

mesin uap (penyebaran tebu( Saccharum officinarum) )


Tebu, Saccharum officinarum L, memiliki sejarah yang panjang sebagai komoditas pertanian komersial. Tebu diperkirakan berasal dari Papua dan mulai dibudidayakan sejak tahun 8000 sebelum masehi (SM). Tanaman ini kemudian menyebar ke berbagai tempat di dunia seiring dengan migrasi manusia, menyeberangi lautan dan mengarungi daratan. Tebu dari Papua menyebar ke kepulauan Solomon, New Hebride dan Kaledonia Baru.

Alkisah dua orang nelayan di Kepulauan Polinesia menemukan potongan batang tebu tersangkut di jaring ikan mereka. Salah seorang nelayan kemudian melemparkan batang tersebut ke darat karena mengira itu adalah potongan batang kayu biasa yang tidak berguna. Beberapa hari kemudian mereka melihat tunas-tunas muncul dan memanjang dari batang tersebut, yang kemudian diketahui sebagai tebu. Setelah itu, tanaman tebu berkembang di berbagai lokasi di Polinesia.

Dua abad kemudian tebu masuk ke wilayah Indonesia tengah dan barat, Philipina, serta bagian barat India. Gula kasar pernah diproduksi di India antara 400 SM hingga tahun 700 M (Masehi). Dari India, tebu dibawa ke China. Di China nira tebu dijemur matahari membentuk padatan yang disebut madu batu. Tahun 500 M tebu mulai memasuki Persia. Saat itu tebu dipakai sebagai pemanis pengganti madu dalam makanan dan minumam. Penyebaran tebu dari Persia ke wilayah yang lebih luas diawali oleh Nabi Muhammad SAW tahun 632 M atau sesaat sebelum beliau wafat ke berbagai wilayah khususnya Jazirah Arab. Tahun 710 M tebu masuk ke Mesir dan selanjutnya menyebar ke Maroko, Suriah, Mediterania, Madeira, dan pulau Canary. Dari Maroko, tanaman tebu menyebar ke Spanyol pada 755 M dan ke Sisilia tahun 950 M.


Buku resep atau Nimmatnamah yang ditulis dalam bahasa Perisia (1495-1505) oleh seseorang yang dipersembahkan kepada Sultan Mandu, Ghiyas-ud-din Khalji. Teks di atas menjelaskan tentang Kheer atau puding susu dan Kheema atau potongan daging berbumbu serta sapi yang menyusui anaknya. Teks di sebelah kanan merupakan saran agar diperoleh susu sapi yang sangat manis dan cocok untuk untuk pembuatan Kheer, maka sapi harus dipilih dengan baik serta dipakani tebu selama beberapa minggu sebelum susunya diperah (Sumber: Brithish Library).

Sekitar tahun 1493 Columbus membawa tebu dari pulau Canary ke Republik Dominika. Ini merupakan langkah awal penyebaran tebu di benua Amerika. Kurun 1500-1700 tanaman tebu menyebar ke daratan Amerika, Meksiko, Brazil dan Peru, kemudian ke Mauritius, Reunion dan Hawai. Tahun 1800-an, tebu mulai dikenal di Australia, Fiji dan Afrika Selatan.

Di Jawa, tanaman tebu diperkirakan sudah sejak lama dibudidayakan, yaitu pada zaman Aji Saka sekitar tahun 75 M. Perantau China, I Tsing, mencatat bahwa tahun 895 M gula yang berasal dari tebu dan nira kelapa telah diperdagangkan di Nusantara. Namun, berdasarkan catatan Marcopolo hingga abad ke-12 di Jawa belum berkembang industri gula seperti yang ada di Cina dan India. Kedatangan orang Eropa, terutama orang Belanda, pada abad 17 membawa perubahan pada perkembangan tanaman tebu dan industri gula di Jawa.

Pada awal abad ke-17 industri gula berdiri di sekitar selatan Batavia, yang dikelola oleh orang-orang China bersama para pejabat VOC. Pengolahan gula saat itu berjalan dengan proses yang sederhana. Sebagai gilingan digunakan dua buah selinder kayu yang diletakkan berhimpitan kemudian diputar dengan tenaga hewan (kerbau) atau manusia. Tebu dimasukkan diantara kedua selinder, kemudian nira yang keluar ditampung dalam suatu bejana besar yang terdapat di bawah gilingan. Pada saat panen tebu, “PG sederhana” ini bisa dipindahkan mendekati kebun.

Pada pertengahan abad XVII telah dilakukan ekspor gula ke Eropa yang berasal dari 130 pengolahan gula (PG tradisional) di Jawa. Seiring dengan perjalanan sejarah, jumlah PG di Jawa turun naik berfluktuasi. Ketika India mulai melakukan ekspor gula ke Eropa, industri gula Jawa mengalami persaingan ketat sehingga beberapa diantaranya tutup. Pada tahun 1745 di Jawa tersisa 65 PG, tahun 1750 bertambah menjadi 80 PG, kemudian akhir abad XVIII menyusut kembali menjadi 55 PG. Fluktuasi ini diduga berkaitan dengan perubahan kondisi lingkungan sekitar Batavia yang tidak lagi kondusif untuk budidaya tebu atau mungkin berkaitan dengan kesulitan permodalan.

Pada awal abad XIX, industri gula yang lebih modern yang dikelola orang-orang Eropa mulai bermunculan. PG modern pertama didirikan di daerah Pamanukan (Subang) dan Besuki (Jawa Timur). Akan tetapi, PG tersebut tidak bertahan lama dan mengalami kebangkrutan yang diduga akibat masalah perburuhan dan ketersediaan lahan sawah untuk tebu yang terbatas. Di Pamanukan, investor gula harus membuka lahan-lahan sawah baru yang butuh modal besar karena lahan sawah yang sudah ada diprioritaskan untuk padi.

Kurun waktu berikutnya industri gula Jawa mulai menggeliat bangkit seiring dengan diberlakukannya Cultuurstelsel oleh van den Bosch. Liberalisasi industri gula Jawa dipasung. Semua aktivitas ekonomi (perdagangan gula) swasta dilarang dan dikuasai sepenuhnya oleh pemerintah kolonial Belanda. Pada tahun 1830 Bosch mengembangkan penanaman tebu di daerah pantura Jawa Tengah dan Jawa Timur, yang dikelola secara profesional. Sebagian besar perusahaan keluarga diserahkan kepada para manajer profesional. Modal didukung oleh Javasche Bank, sedangkan manajemen inti dipegang orang-orang Eropa. Usaha-usaha penetrasi pasar dilakukan pemerintah Belanda melalui regulasi impor gula dengan memberikan potongan 15 gulden untuk setiap pembayaran cukai sebanyak 100 gulden. Tenaga kerja hampir sepenuhnya tidak dibayar alias gratis karena unsur paksaan oleh para penguasa bumiputra yang berkolaborasi dengan para penjajah. Perubahan kebijakan ini berhasil baik, dimana 10 tahun kemudian gula dari Jawa mampu mendominasi pasar dunia. Perkembangan berikutnya, beberapa PG mulai bermunculan di Jawa dengan dukungan pembangunan infrastruktur besar-besaran terutama dalam penyediaan sarana irigasi.

Kebangkitan industri gula di Jawa pada masa itu sebenarnya terkait juga dengan perubahan teknologi. Margarete Leidelmeijer dalam studi Doktornya di Universitas Teknologi Eindhoven, Belanda, tahun 1995 menulis disertasi tentang industri gula di Jawa berjudul Van suikermolen tot grootbedrift. Technische vernieuwing in de Java-suikerindustrie in de negentiende eeuw atau dalam terjemahan bebas kira-kira artinya “dari pengolahan gula sederhana ke pabrik-inovasi teknik pada industri gula Jawa abad sembilan belas” (No. 25 dalam seri NEHA 111, Dutch Guilders). Menurut Leidelmeijer, sejak Cultuurstelsel diberlakukan teknologi industri gula Jawa sebagian mengadopsi teknologi pengolahan gula bit di Eropa, salah satunya dengan menggunakan pan masak vacuum. Selain itu, dukungan para insinyur dan peneliti di Belanda yang difasilitasi kantor Kementrian Pemerintahan Kolonial ikut terlibat dalam pengembangan industri gula Jawa. Kontak antara para pelaku industri gula di Jawa dan Eropa saat itu cukup intensif. Mereka saling bertukar informasi tentang teknologi prosesing gula tebu dan gula bit. Industri gula Jawa pada akhirnya berkembang cukup pesat dan bahkan menjadi acuan bagi industri gula tebu dunia lainnya. Inovasi teknologi prosesing gula tebu yang dimulai abad XIX tersebut, kemudian disempurnakan dengan berbagai inovasi teknologi di abad XX hingga saat ini masih bertahan dan dipakai oleh sebagian besar PG Jawa.



Micro air separation System


Overview
Advances in providing high aeration levels and intimate contact between bubbles and the dispersed phase have led to a novel separation system, the Micro Air Separation System (MASS). The MASS significantly reduces costs, provides unrivalled separation efficiencies, uses dramatically less chemicals and less space and can perform separation operations previously impossible to achieve using traditional Dissolved Air Floatation (DAF) systems.

There are a number of key functional principles DAF systems must adhere to:

High surface area micro bubbles must be formed to maximize effluent separation. The MASS bubble size and surface area can be controlled by varying the back-pressure and the airflow rate. That the micro bubbles are stable and re-active towards the dispersed phase is of key significance.
Increasing the concentration of bubbles maximizes the lift performance. The MASS unit processes all the wastewater flow and air through a pressurized cyclone. The air dissolves and all process flows are intimately mixed in the highly aerated water.
The smaller micro bubbles adhere better to the fragile flocculated particles. The MASS produces micro bubbles that form multiple contacts and because all the process flow is being aerated, superior lift is achieved leading to high sludge concentrations.
The method of pressure control throughout the circuit is paramount for quality bubble production. The MASS is novel in that the dispersion of micro bubbles in the floatation tank is vastly improved due to the method of dissolution down the cyclone chamber.
Features and Benefits
Superior separation of contaminants. Up to 95% reduction in Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS).
Air aspiration straight from the atmosphere. No air blower or compressor required.
Small footprint reduces capital costs.
Minimal maintenance.
Process efficiency improvement. Allows for the capture and reuse of more valuable resource material, while producing water that is cleaner than water generated from competitive systems.
Modular design and ease of scale-up.
Reduced chemical consumption.
More compact sludges.
How does the MASS work?
The MASS system exploits the density difference between two phases primarily by attaching air bubbles to one phase and floating it away for collection. This idea is not new, but the method by which it is achieved using the MASS is set to revolutionize how we think about DAF systems.

The MASS works by dissolving free air from the atmosphere in a cyclone within the unit, which allows up to five times more air to be dissolved than a traditional DAF system. The pressures and forces created ensure intimate mixing of the air and the fluids to be separated, which causes the air to be fully dissolved rather than entrained. The pressures generated within the MASS are up to two times that created in traditional DAF systems thereby, further increasing the amount of air available to strip out suspended solids.

The MASS unit was designed with no moving parts. The fluid spins itself through specially designed channels, and because this is achieved without moving parts, maintenance costs are reduced significantly.

To realize effective effluent separation, it is often necessary to adjust the electro-potential (pH) of the wastewater, in addition to utilizing an air floatation system. It is also possible to use chemicals such as coagulants and flocculants to help create surfaces or structures that can easily attach to the air bubbles. Coagulants are used to bind the particulate matter together and flocculants are used to change the surface tension on the liquid/solid and or liquid/gas interfaces. The combination of all three regimes will almost always bring about separation. However, using the MASS technology, it is usually sufficient to utilize one or two of these regimes and still accomplish a satisfactory result.

air tower technology

Typical LNG regasification facilities utilize boil-off gas (a portion of the LNG) to fire heaters in order to regasify the remaining LNG, thus creating nitrogen oxide (NOx) emissions. NOx is a compound that has been associated with air pollution. Freeport LNG uses a different, patented, system that is designed to draw heat from the air to regasify the LNG. This process involves the use of towers which are similar to cooling towers that are commonly used in many industries. During summers (and much of the spring and fall) along the Texas Gulf Coast, large amounts of heat can be taken from the air with the proper equipment. Freeport LNG designed a tower that utilizes this ambient air temperature. This technology allows Freeport LNG to operate its plant within the Houston-Galveston non-attainment area since the towers don’t emit NOx at all. During cooler weather, when there’s not enough heat in the air, we convert to heaters similar to other LNG terminals. While it will vary from year-to-year, we expect that the warming tower can be used for up to eight months of a year. In summer, when ozone and NOx levels typically rise in the Houston-Galveston airshed, Freeport LNG’s warming towers won’t contribute to this rise.

christ water technology


Compared with conventional EDI modules, the special hydrodynamic design of the SMH 3000 permits a higher sanitisation flow rate of up to 70 per cent of the ultrapure water output with a pressure drop of 1 bar. The innovative electrodeionisation method of CHRIST fully complies with our responsibility for the environment. Pre-treated water (e.g. of a reverse osmosis stage) flows into the patented SEPTRON® module, where it is continuously deionized.

This is carried out with an electric current, without the need for chemicals and with only a low power consumption. Water enters a chamber which is filled with an ion exchanger. The electrical potential applied to the electrodes causes charged ions, such as sodium and chloride, to pass through the ion exchange membrane into a concentrate chamber, from which they are discarded. The ion exchanger inside the SEPTRON® module reduces the electrical resistance, which means that the power needed to achieve the desired deionisation is also low.

This method permits the removal of ionic components out of the water without increasing the total amount of salt (from the viewpoint of the entire process).

SEPTRON® Modules are available for 500, 1'000 and 3'000 l/h as SM series for cold water applications and as SMH-series for hot-water sanitisation.



water technology


For one water treatment supplier, 2008 turning out to be a very busy year, despite the downbeat economic forecasts.

Siemens Water Technology (SWT) has won a number of significant water treatment contracts in the US, including one large technology licensing deal.

The licensing agreement is with CSO Technik to supply and service the Crown sludge disintegration system in the US, Canada, and Mexico. The US patented cell lysing process eliminates digester foaming, increases gas production by up to 30 per cent and reduces solids for disposal by 20 per cent.

The Crown system complements Siemens’ Dystor dual-membrane gas holder system that captures biogas produced by the anaerobic process. The Crown agreement will round out Siemens’ anaerobic digestion product portfolio, making it a leader in the municipal biogas market in North America.

The Crown disintegration system is installed after the sludge thickeners but before the digester. Sludge is first fed into the system’s recirculation tank. It then goes through a homogeniser. The uniform mixture is then pressurised to 175 psi and pumped through a high-speed mixer and into the disintegrator.

As the pressure is relieved, the biosolids cells rupture and release endo- and exo-enzymes and destroy filament-building micro-organisms. The disintegrated sludge is then sent back to the recirculation tank, where the process is repeated before being discharged into the digester.

The Crown system partners with Siemens’ Dystor dual-membrane gas holder system, which maximises gas storage through its geometric shape. The latter’s many operational advantages makes the Crown – Dystor synergy a combination unequalled in the industry, says the company.

The Crown sludge disintegration technology is ideal for a variety of municipal wastewater treatment applications. Existing customers with co-generation facilities can pair the unit with Siemens’ Dystor gas holder system to maximise system potential through increased gas production and storage. The system can also prove beneficial for customers that live in areas with green energy or self-generation tax incentives as well as for municipalities that have other high-volume biogas end-users.

Compared to a competitive physical/chemical cell lysing process, the small footprint Crown process consumes less energy and greatly reduces chemical, equipment, and sludge hauling costs. Pre-fabricated and containerised for fast installation, the Crown process is adaptable to variable loads and improves sludge dewaterability and digester stability. The system also uses equipment that is common to most wastewater treatment plants. The Crown disintegration process is already operational at several wastewater treatment plants worldwide.

A second deal involves a contract to provide secondary clarification systems for the Metro Wastewater Reclamation District’s (MWRD) North Secondary treatment complex improvements project in Denver. The plant upgrade will include twelve 130-foot diameter Tow-Bro clarifier mechanisms for secondary treatment.

The new clarifiers will improve performance over the existing organ pipe type clarifiers – specifically, improved energy dissipation and velocity profile control, improved flocculation, and even sludge withdrawal, particularly important under poor solids settling conditions. The project is scheduled for completion in 2012.

The Robert W Hite Treatment Facility serves a population of approximately 1.6 million in the metropolitan Denver area. Improvements to the North Secondary treatment complex were needed to replace aging clarifier equipment, increase solids and hydraulic loading capacity, and improve overall treatment performance.

The District worked with Carollo Engineers, HydroSims and CPE Services using plant specific settling analysis, computational fluid dynamic (CFD) modelling, and full scale stress testing to determine the best solution to meet the plant’s final clarification requirements. The engineering firm recommended the Tow-Bro clarifier mechanism.

The advantages of the Tow-Bro unit include uniform sludge removal from the secondary clarifier under a wider variety of flow, solids loading, and sludge settling conditions. These advantages provide greater solids and hydraulic loading capacity when compared to the existing hydraulic-removal-type clarifiers. The clarifier design utilises a centre-feed configuration with peripheral effluent launders. Flow enters the clarifier through a specially designed maze type energy dissipating inlet (EDI). The specific configuration of the maze EDI was designed with the assistance of CFD modelling to determine optimal dimensions.

After initial energy dissipation, solids are flocculated and settle to the tank floor where they are removed uniformly by the Tow-Bro unitube header. Concentrated settled sludge is returned to the aeration basin from the clarifier. Clarified effluent flows into an inboard launder and exits the tank. Scum is removed via a ducking skimmer assembly. The treated water then flows to the Metro District’s disinfection facilities for further treatment prior to discharge into the South Platte River.

The new clarifier mechanisms will be installed in multiple phases over the next three years. To minimise the impact of construction on plant capacity, Garney Construction of Littleton, Colorado, will replace three of the 12 clarifiers at a time. The existing clarifiers will remain online until they are replaced with the new Tow-Bro mechanisms.

A third contract is for the delivery of five IPS composting system agitators to the Burlington County, New Jersey Board of chosen freeholders, as part of an upgrade to the county’s ten-year-old composting plant.

The plant supports the county’s biosolids composting and beneficial use programme for 14 municipal wastewater treatment plants.

The new IPS equipment will replace the plant’s existing ten-year-old Siemens’ composting agitators. Two agitators will be delivered this year, with the other three installed in early 2009. This schedule will allow the capital cost to be spread out for two fiscal years, and the entire order delivered within the shortest time frame so as not to impede plant operations.

The IPS composting system is an enclosed in-vessel, agitated, aerated, automated composting process with biofiltration odor control. It transforms dewatered biosolids, municipal solid waste and source-separated organics (SSOs) into high-quality compost products. The system also stabilises residual waste in mechanical biological treatment.

At Burlington County, Siemens conducted on-site composting system studies to help determine the best plan for implementing the upgrade while meeting the county’s budget. The company also worked with its suppliers to meet the challenge of a relatively tight timeline. The new IPS equipment will allow the county to continue its success managing biosolids from the wastewater treatment plants, thus providing beneficial use of the compost product and reducing greenhouse gases to the environment.

SWT also announced in August that it is to provide Meriden in Connecticut with second supervisory control and data acquisition (SCADA) system, valued at US$1.3 million.

The city’s latest system, to be installed as part of an upgrade at its 11.6 million gallons/day water pollution control facility, will be compatible with the SCADA system supplied by Siemens to Meriden’s water division facilities in 2002.

Once the new SCADA system comes online in early 2010, it will allow the city to control and monitor 1550 process-related database points, make informed decisions regarding the operation of the pollution control facility, and optimise process operations. This, in turn, will improve the facility’s effluent.

Siemens’ scope of supply includes SCADA system hardware and software application engineering, facility-wide instrumentation and controls loop drawing documentation, and project management coordination. SCADA system factory staging and testing will be included as part of the contract, as well as a formal customer/city factory witness test.

Field service support will include onsite installation supervision, field readiness testing, system start-up and commissioning and a formal customer/city test for final SCADA system acceptance. Siemens will also provide Meriden’s operations and maintenance personnel with onsite formal training in the use, maintenance and troubleshooting of the pollution control facility’s new SCADA system.

solar plane


The Sunseeker II features solar panels on very small wing areas, and it has an ultralight shape. This solar airplane was designed by Eric Raymond and it’s going to fly above Europe this late-Spring and in the early-Summer when the Sun will shine with more power.

The Sunseeker II will fly in Freidrichshafen, Germany between April 2-5, and in Torino, Italy between June 6-14, but it’s also expected to fly in the Swiss Alps, Australian Dolomites, Slovenia, France, and even Spain.

The Sunseeker II was inspired by Gunther Rochelt’s Musculair MPA’s, and using Gunther’s concept, the designer, Eric Raymond, developed his own hybrid aircraft that needed batteries to take off and increase altitude, but when maintaining level, the plane would run on solar power. Its battery pack is very small, and it would only take 90 minutes for a full recharge as the extra solar energy would go to the batteries. The designer says that he has never been forced to land before late-afternoon and that it’s very comfortable to fly with the canopy open thanks to its slow speed.

“The magic part begins when I near cloud base. With my batteries full, or nearly so, I switch on the motor, and climb up between the clouds, once on top, I can throttle back to fly on direct solar power in the clear, bright conditions over the clouds. Under direct solar power, the Sunseeker II is basically a one-speed airplane, flying about 18 m/s. When soaring conditions are present or if the batteries are used, faster speeds near 36 m/s are possible,” said Eric Raymond.

According to Eric, the Sunseeker II is so quiet that birds are not scared of it, they come near it, and they even land on the solar powered airplane.

Boat is $25,000 USD, complete and ready to enjoy.

The first zero-emission, solar-electric boat to ply Ontario’s historic Trent-Severn Waterway, called “the Loon”, is now being manufactured and made available for sale to environmentally conscious boaters around the world. This entirely unique boat, which carries up to 8 passengers in comfort, is unlike any boat previously manufactured in more ways than just its lack of exhaust trail in the water.

“I designed the Loon to address a number of areas lacking in conventional boats, making the Loon the ideal craft to enjoy the natural splendor of Ontario’s lakes and inland waterways” stated its inventor and boat builder, Monte Gisborne, president of the company which is now building these boats for retail sale. “Everything from the seating arrangement to pontoon design to the propulsion system was designed to minimize man’s impact on the ecosystem while maximizing enjoyment on the water”. The result is a boat which probably won’t satisfy the go-fast waterskiing crowd, but should attract a lot of attention from people who enjoy a more relaxing ride, particularly the baby boomers. The chosen hull is the aluminum pontoon deck boat, the most popular style of boat today with North America’s aging population.

A prototype boat (shown above) was built and tested last summer to determine the viability of solar-powered boats. A trip down the Trent-Severn Waterway was completed in August; Gisborne felt so confident in his invention that the family came along for the ride. He summarized that trip “Miles traveled: over 100. Cost of fuel: zero. Reaction from boaters who never expected such a boat to make the trip: priceless”. The results of this trip encouraged Gisborne to bring the product to the market. Some timely seed capital was raised and a suitable production facility at Starport Landing Marina on Lake Simcoe was discovered. After months of further development work, the first production boat was completed, with many improvements over the original prototype.

The sale of the first boat came as a bit of a surprise to Mr. Gisborne; the call didn’t come from a Toronto cottager, but from Belize, Central America. An entrepreneur from there wanted to take people on guided tours to see the indigenous species of Howling Monkey, but found out that only zero-emission boats were permitted. “Gas boats were not allowed so I began to search out options. The Loon seemed perfectly suited to my needs so I contacted Mr. Gisborne” stated Byron Chu, president of Maya World Promotion Ltd. Further research on commercially available solar-powered boats yielded higher-priced and less-capable vessels from abroad, so Mr. Chu put in his order for a Loon, which he will take delivery of this month.

With the price of gas like it was after Katrina ($1.90 per litre at marinas) and the detrimental effects of internal combustion, people are becoming more sensitive to the issue of burning fuel purely for pleasure, believes Gisborne. “Exhausting hydrocarbons directly into your own lake isn’t much different from urinating in your own family recreation room”, he states. “We need sensible options if we want to leave something for future generations to enjoy… and I believe that water and electricity do mix!”

RTEV begins takingorders for wheego chip electric car

If you’re the type of Earth-loving individual who ain’t got nowhere to go in a hurry, RTEV’s ready and willing to take your order a brand new Wheego Whip. The company’s first street electric LSV (low speed vehicle) will begin shipping to early adopters in May, and it’s primed to carry up to two individuals and a few empty cola bottles anywhere you need to go — so long as there’s an AC outlet waiting at Point B. It’s retailing for under $19,000 and includes an MP3 stereo system, remote keyless entry, air conditioning and a sweet 10 percent Federal Tax credit. Of note, RTEV has plans to eventually produce a higher speed model of this very car, and there’s a trade-in program available (with terms that aren’t half bad) for those interested. For all the fine print, give that read link a tap.

Skysail


Indonesia adalah negara kepulauan dengan lautan yang sangat luas, pesisir pantai terpanjang di dunia dan juga memiliki sungai-sungai besar yang merambah jauh ke dalam hutan. Oleh karena itu, transportasi sungai dan laut sangat penting bagi Indonesia. Tetapi kapal-kapal yang ada saat ini semua digerakkan oleh energi minyak. Saya pernah menulis satu artikel mengenai kapal yang berhasil melintasi Samudera Atlantik hanya dengan energi matahari. Tetapi ternyata teknologi untuk energi alternatif dan terbarukan untuk dunia perkapalan sudah semakin baik, bukan hanya teori dan sudah mulai diimplementasikan. Beberapa sudah terbukti, beberapa masih berupa konsep yang walau sudah dibuktikan tetapi masih dalam lingkup yang kecil dan bukan untuk komersil.

Teknologi pertama yang sudah dipakai secara komersil adalah SkySail. SkySail memiliki produk seperti layangan/parasut yang menggunakan tenaga angin untuk membantu menarik kapal maju. Disebutkan bahwa SkySail bisa menambah tenaga kapal hingga 5000 kW atau setara dengan 6000 HP. Dengan tambahan tenaga ini, maka kapal bisa menghemat 10-35% bahan bakar minyak kapal dan bila angin dalam keadaan optimal bisa menghemat hingga 50% penggunaan bahan bakar minyak. Ini sungguh mengagumkan dan sudah diimplementasikan di kapal kargo MS Beluga di Jerman yang diluncurkan pada tanggal 18 Januari 2008.

Kapal cepat dengan bahan bakar Biodiesel yang sedang diuji coba adalah EarthRace yang diprakarsai oleh Pete Bethune. Kapal EarthRace dapat bergerak dengan kecepatan maksimum 40 knot (75km/jam). EarthRace sedang dalam tur keliling dunia untuk menggalang dana dan juga memberi edukasi kepada negara-negara di seluruh dunia mengenai Biodiesel. Di website EarthRace, anda juga bisa melihat map dimana dia pada saat ini.

Teknologi lainnya yang sedang diuji coba adalah kapal dengan tenaga ombak yang bernama Suntory Mermaid dan dalam upaya untuk berlayar dari Hawaii menuju Jepang hanya dengan menggunakan tenaga ombak. Panel surya yang anda lihat di atas kapal hanya untuk peralatan elektronik saja. Cara kerjanya? Arus ombak yang ada di bawah kapal akan mengena sirip-sirip yang ada di bawah kapal dan akan bergerak naik turun. Nah.. dari pergerakan naik turun ini akan diubah menjadi energi dan dalam prakteknya kapal dapat bergerak hingga kecepatan 5 knot.


Dari semua teknologi ini, tentu semuanya memiliki keuntungan dan kelemahan sendiri-sendiri. Untuk saat ini tenaga arus ombak masih sangat pelan, tenaga surya sudah sangat cocok untuk menjadi sumber energi untuk peralatan elektronik dan angin pun bisa menolong kapal mengurangi penggunaan bahan bakar minyak. Semua energi alternatif ini akan terus berkembang semakin kemampuannya pun semakin baik dan efisien.

Mudah-mudahan semua teknologi ini juga semakin terjangkau untuk komersil terutama untuk pemakaian di Indonesia sehingga bukan saja bisa mengurangi ketergantungan kita pada bahan bakar minyak, tetapi dengan energi alternatif yang terbarukan maka lingkungan pun akan semakin baik, resiko pencemaran minyak dan polusi pun berkurang.

Kita tunggu saja tanggal mainnya.
