A company called Advanced Linead Devices, from Sunnyvale, CA, has designed a MOSFET (a power transistor, you may have one your stereo at home - it basically looks like the picture above) that can open itself to very tiny, small, voltages, and it's called "zero-threshold MOSFET".
I was wondering what else is Toyota doing for a complete environmentally friendly car. And there was the FT-EV concept.
North American International Auto Show in Detroit brought in sight several car companies interested in hybrid and electric cars. Ford Motor Co in planning by 2011 to implement fully electric cars that have an autonomy of at least 160 km on a single charge. Ford will also offer gas-electric hybrid cars by 2012.
The smallest hydrogen fuel cell of just 3mm diameter was created by US chemical scientists and could replace batteries in portable electronics devices.
While most new inventions are for wealthy people, with some social status, once in a while there are inventions aimed to help the poor and provide the minimal sanitary conditions through simple and inexpensive methods.To get one liter of boiling water you need one kilo of firewood. People living in areas with no safe water usually spend 3-10% of total income/year on water.
Like the 3.9 seconds 0-60 acceleration wasn't enough, Tesla has unveiled on Sunday the faster "Tesla Roadster Sport" at the North American International Auto Show in Detroit.
Luca Technologies started up a project to produce natural gas from coal. The idea is to use microorganisms inside the coal layers of earth to change coal into methane.
While nobody seems to speak much about them, solid acid fuel cells are actually a much cheaper way to produce energy from impure hydrogen sources, with much more flexibility than PEM fuel cells have.
Films of carbon nanotubes could be used to store lithium or liquid electrolytes in future battery electrodes. The capacitance of the films is one of the highest ever measured for carbon nanotubes.
Electric motors have simple designs, are easy to operate and have a great resistance to various environments. That's why they are to be chosen as alternative to internal combustion engines. This is a trivial experiment showing how you can feel you made a real electric motor yourself. Just for fun.
