The Battery Wizard is a new gadget that tries to re-enable batteries otherwise good to be thrown away. Of course, rechargeable batteries are always handy and ready to be charged, but for ages I've known that trying to charge a normal, single use battery ended up in an explosion.
Google Inc is planning to develop its own mirror technology for solar energy that could be more cheaper and accessible to the masses, reducing the cost of building solar thermal plants by a quarter or more.
Since their invention in 1800 by Alessandro Volta, batteries have become a common power source for houses and industrial applications and hystory has proven that modern society cannot live without them.
Researchers at the Uppsala University in Sweden, have developed a new thin-film battery made from salt and cellulose. This salt and paper battery uses a thin-film which makes it an attractive feature for many portable devices that draws a low current.
Researcher Leonard Ornstein has come up with a simple plan to stop global warming. He proposes that turning Sahara and the Australian outback into vast, shady forests, could draw down about 8 billion tons of carbon a year, nearly as much as people emit from burning forests and fossil fuels today.
Jerry Block, a retired anesthesiologist, located in Monte Sereno, California, has developed in his backyard a rainwater harvesting system, capable of holding and collecting up to 20,000 gallons of rainwater each year.
The company Mitsubishi Electric has developed ten new models of high-output solar cells: five for the European market and the rest for North America and Asia. The new solar panels have the outputs ranging of 210W, 220W, 225W, 230W and 235W.
A chemistry professor from the University of Missouri may have found a way to clean radioactive metal contamination. The bacteria-based solution is able to work in this challenging business where most of technologies were too expensive or sometimes did not work.
Scientists at the University of Queensland have designed stick-on solar cells made from low-cost plastics, being cheaper than the silicon panels fixed to rooftops.
To reduce energy consumption, Denali Education Center has come up with an idea to install a hot water system, and they managed to make it one of the largest in the state.
