So a larger solar celled powered car, is not that much further in logic's demands.

Well if you think so, then go for it! I'd love to see the product. You'd beat a lot of big companies to market if you could. But as I say above, I don't see anything viable in an "all solar" car for at least 10 years, and even then the market will be limited to areas with lots of sun. Certainly, Seattle and environs are out of the question.

Dec. 10, 2004 — Aaron Goldin this week won the grand prize at the Siemens Westinghouse Competition in Math, Science and Technology for his invention that harnesses the ocean — 70 percent of the world's surface — to create energy.

"I call [it] 'gyro-gen,' and it generates electricity from the power of rolling ocean surface waves," said the 17-year-old high school student from Encinitas, Calif.

Goldin, who loves to tinker in his family's garage, used parts from an old answering machine, tape recorder and computer printer to make a spinning gyroscope. When floated on the ocean — inside a buoy, for example — and rocked back and forth by the waves, it converts the waves' power into electricity.

Goldin and his dad traveled to Washington where — competing against 1,200 high school students from all over the country — he presented his invention to a panel of leading scientists.

"It's fun," said Goldin. "It's an intellectual exercise. It's something that you can do that really forces you to look at things in a different way, and it's a very fulfilling activity to be able to try new things and discover new things."

Goldin was awarded a $100,000 scholarship to any university he wishes to attend.

"When you have a goal," said Goldin, "when you have an end in mind and you finally have created something, it's really fun to actually see it work."

The judges found him to be incredibly creative and passionate.

"His eyes light up when he's talking about technology," said Roger Falcone, professor of physics at the University of California, Berkeley. "He has an enthusiasm that he brings to his work that is absolutely unique."

“Autonomous Gryscopic Ocean-Wave Powered Generator: Invention of a New Energy Conversion Technology”

http://www.siemens-foundation.org/2004/UC%20Berkeley/Aaron%20Goldin.htm

In his project, Aaron Goldin invented an autonomous device that directly converts ocean wave energy into electricity using the principle of gyroscopic precession. It offers a practical alternative to renewable energy generation technology. Mr. Goldin strongly feels that there is a need to repair the damage that has been done to the planet’s biosphere caused by the burning of fossil fuels. He sought to invent an environmentally friendly alternative to generate energy that is non-polluting, renewable, practical and efficient. Mr. Goldin’s invention can be a power source for remote oceanographic research instrumentation and communication, deep-sea exploration and surveillance. It also has practical applications in autonomous gyroscopic wave-powered generators supplying energy to deep-sea hydrogen fuel conversion farms.

Mr. Goldin, a senior, has won a number of awards, including the first Award (Grand Award) for Engineering at 2004 Intel ISEF, three Organizational Awards, Governmental Award for the US Coast Guard and first place for Electronics and Electricity at the 2004 California State Science Fair. Mr. Goldin, 17, is also an accomplished musician. He has played with the North County Symphony Orchestra, North County Youth Symphony Orchestra and “Band in Black,” a local Jazz Band. He enjoys composing music, piano improvisation, classic music audiophile and reading novels. At school, he is a member of the school literary magazine, National Honor Society and Interact (volunteer) Club. He plans to study physics and engineering in college and hopes to become a university professor.



Autonomous Gyroscopic Ocean-Wave-Powered Generator:

Invention of a New Energy Conversion Technology

Abstract: Oceans cover over 70% of the earth’s surface and are its largest energy

storage system. Efforts to tap the 2000TWh/yr of available wave energy encounter serious engineering obstacles. If an autonomous wave energy converter (WEC) could be designed to directly convert the power in ocean waves (of varying frequencies and amplitudes), it might overcome difficulties in current WEC technologies.

A prototype WEC, incorporating a gyroscope and electric generator ("Gyro-Gen"), was designed, built and tested. Trials recorded output power versus gyro angular velocity, generator electrical load, and slope frequency. Sea tests were performed. Data show a direct relationship between gyro rate, output power and electrical load. The small prototype autonomously powered the gyro while delivering 0.817W into an auxiliary load. A theoretical model of power output and efficiency was developed that accurately predicted experimental results.

This novel configuration applies gyroscopic precessional torque to directly convert the periodic kinetic energy of surface waves into continuous torque that drives a rotary electric generator. Gyro-Gen requires no transfer system used in existing WECs, avoids corrosion and rough-sea-damage, and is scalable to much greater power outputs.

This design offers a new approach to a practical, alternative, renewable energy generation technology.

Note to self (and others): All wave phenomenon are frequency effects. They all possess Energy which can be tapped into. All Energy has Frequency as its fundamental. Frequency of Time, but also of Mass and Space.

Each and every one of us is truly, physically, and scientifically..... a wave-rider.

Imagine wearing a jacket or rucksack that charges up your mobile phone while you take a walk. Or a tent whose flysheet charges batteries all day so campers can have light all night. Or a roll-out plastic sheet you can place on a car's rear window shelf to power a child's DVD player.

Such applications could soon become a reality thanks to a light, flexible solar panel that is a little thicker than photographic film and can easily be applied to everyday fabrics. The thin, bendy solar panels, which could be on the market within three years, are the fruit of a three-nation European Union research project called H-Alpha Solar (H-AS).

The new solar panels will be cheap, too, because they can be mass-produced in rolls that can be cut as required and wrapped around clothes, fabrics, furniture or even rooftops. "This technology will be a lot easier to handle than the old glass solar panels," claims Gerrit Kroesen, the physicist from Eindhoven University of Technology in the Netherlands who led the development team.

Kroesen's team has made its solar cells bendy simply by making them thin. But this has involved a trade-off. While the best solar cells are now working at efficiencies above 20%, the H-AS cells are only about 7% efficient. The researchers think efficiency is worth sacrificing for a cell that is going to be more generally useful, though they still hope eventually to reach 10% efficiency.

Electron knockout
Conventional solar panels are made of pairs of sheets of semiconducting silicon, doped with phosphorus and boron atoms. Electrons in the phosphorus-doped (N-type) layer migrate across the boundary to occupy holes left in the boron-doped (P-type) material, setting up a voltage across the boundary between the two layers. When photons hit the silicon in a cell they knock electrons out of its crystal structure, generating a current that is collected by a mesh of metal contacts.

The H-AS solar panels are constructed in a similar way, but they are made just 1 micrometre thick by depositing polymorphous silicon at high pressures and temperatures. "Polymorphous silicon is as rigid as crystalline silicon. But because it is less than a micrometre thick it is flexible," Kroesen says. Today's solar panels are typically somewhere between 4 and 10 millimetres thick.

The process of producing H-AS films involves temperatures of up to 200°C, which would melt a plastic substrate. So instead of depositing the doped layers directly onto plastic they are first deposited onto aluminium foil.

After the assembly has cooled, a plastic carrier layer is added underneath it and the aluminium is removed and recycled. Contacts are then added, followed by a protective plastic layer on top, too. This sequence lends itself to continuous production on rolls of plastic film.

The Swedish and Dutch-owned company Akzo-Nobel, a partner in the H-AS research, already has a pilot plant producing rolls of silicon cells 40 centimetres wide. A projected full-scale manufacturing plant would produce panels at a cost of about 1 euro per watt. An A4-size panel sewn onto the back of a jacket and costing less than 10 euros would charge a mobile phone during a summer stroll. The company has not yet decided to go ahead with the plant.

Jeremy Leggett, chief executive of the UK solar cell supplier Solar Century, is impressed, describing the 1 euro per watt price point as "breathtaking".
