I Charge My Batteries With Water. How About You?
You go somewhere for the holidays. You have your mp3 player to forget about the "dead times" during not-so-interesting-travels. But what? Suddenly your mp3 player stops working! Noooo!
Freshwater and Electricity Through Osmosis
Robert McGinnis, Yale doctoral student and Menachem Elimelech, Chair of Chemical and Environmental Engineering, have developed systems that can harness the power of osmosis to transform non-potable water sources like seawater to freshwater and generate in the same time electricity.
New MOSFET-based Device Makes Ultra Low Power Green Sources Usable
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".
Smallest Hydrogen Fuel Cell for Use in Tiny Portable Gadgets
The smallest hydrogen fuel cell of just 3mm diameter was created by US chemical scientists and could replace batteries in portable electronics devices.
Solvatten: Solar Powered Water Purifier for the Poor
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.
Natural Gas To Be Produced by Coal Eating Microorganisms
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.
Superprotonic Solid Acid Fuel Cells: a Hidden, Cheap, Easy Way to Maintain Power Source
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.
Carbon Film Nanotubes to Be Used in Storing High Amount of Charge
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.
3D Solar Cells Evolution Helped by Nanotubes
Cornell University and DuPont research team started working on a project which will probably revolutionize the electronics industry. The goal is to go to thinner, lighter and more flexible transistors and solar cells. With the use of nanotubes, an economical electronics material will be made which should be as good as silicon.
UK to Get Up to 1 GigaWatt of Free Electricity From Gas Pressure
Engineers from UK's National Grid and a company called 2OC want to built inside the gas pipes mini turbines to produce energy using the gas pressure.
