alternative energy: mixing entropy battery creates power from interaction of rivers and seas

Will we continue to fund new, renewable energy research as President Obama suggests, or take a step back and de-fund alternative energy research under the guise of deficit reduction as Congressional Republicans propose? With gas prices threatening to hit $5 a gallon, the decision appears to be an obvious no-brainer (although brains seem to be a commodity in short supply in Washington).

Scientists at Stanford University are reporting the development of a new battery – a so-called “mixing entropy battery” – that extracts and stores energy produced from the difference in saltiness literally at the point where freshwater in rivers flows into oceans.

A report on the battery, which could potentially supply about 13 percent of the world’s energy needs, appears in the current ACS journal of Nano Letters(more…)

Countdown to Earth Day: green tip of the day, use rechargeable batteries

Earth Day is Friday, April 22 – we’re featuring a green tip of the day from April 1-22.

Today’s batteries are filled with heavy duty toxins – metals and carcinogens – that pollute our land and seep into our water-table, adversely affecting our food, water and entire ecosystem.
