Liquid battery could cut need for new power plants

Engineering professor Donald Sadoway used an old-school chalk board at the prestigious TED gathering on Thursday to write the formula for a liquid battery that could one day cut the need for new power plants.

"The way things stand, electricity demand must be in constant balance with supply," Sadoway told the tech-savvy audience in Southern California.

Inexpensive batteries made from liquid metal could store electricity from solar panels, wind farms, or existing generation facilities and save it for when it is most needed.

A Big Jump in Battery Capacity

Battery packs can cost more than $10,000, which is one of the biggest reasons electric cars cost more than conventional gas-powered cars.

Envia, a startup funded by GM and the U.S. government's Advanced Research Projects Agency for Energy (ARPA-E), says it has built batteries that store more than twice as much energy as the ones in electric cars now. If the technology comes to fruition, it could halve the cost of batteries—the most expensive part on an electric vehicle.

Waste, Microbes, and Novel Energy Sources

Thu, 09/08/2011 - 8:39am -- Jeffrey Tang

Waste-to-energy solutions are among the most attractive options for renewable energy.

Turning a waste product into useful energy is a win-win, saving disposal costs while simultaneously providing renewable energy.  A whole range of these systems are either available or under development -- see our Biomass section for more information on some of these.  But this article and video from the NSF recently caught my eye as a potentially outstanding breakthrough.

Batteries That Run On Used Toilet Water

Humans should have a little more respect for dirty toilet water. In recent years, wastewater has become something of a commodity, with nuclear plants paying for treated wastewater to run their facilities, cities relying on so-called "toilet to tap" technology, and breweries turning wastewater into biogas that can be used to power their facilities. Soon enough, wastewater-powered batteries may even keep the lights on in your house or, at the very least, in the industrial plants that clean the wastewater.
