It’s a prototype hybrid car that gets 150MPG, and goes 40 miles on electricity alone, drawing its power from a combination of lithium-ion batteries and ultracapacitors. The ultracapacitors provide a burst of energy to the engine, when needed. They are then recharged by the lithium-ion batteries. This avoids the problem of emptying the batteries too… [Continue Reading]
Storing Sunshine Using Flow Batteries
July 17, 2007 by 2 Comments
Flow batteries are a unique kind of battery — they have tanks that hold hundreds of gallons of the chemicals, called electrolytes. Flow batteries just happen to be very good at storing solar or wind power. Renewable power sources suffer from being intermittent, and less reliable for continuous power supply than coal or gas. Neither… [Continue Reading]
Report: Solar Costs To Match Coal By 2010
April 9, 2007 by Leave a Comment
The cost of producing solar power will fall to that of coal-fired electricity by the end of the decade, according to a report by Europe’s Photon Consulting. However, falling costs of production won’t lead to substantially cheaper prices for consumers because of current market dynamics which see rising demand outstripping supply. The report predicts that… [Continue Reading]
