Harvesting electricity from living trees

Trees could be the ultimate in green power - tech - 10 September 2009 - New Scientist
Shoving electrodes into tree trunks to harvest electricity may sound like the stuff of dreams, but the idea is increasingly attracting interest. If we can make it work, forests could power their own sensor networks to monitor the health of the ecosystem or provide early warning of forest fires. Children the world over who have tried the potato battery experiment know that plant material can be a source of electricity. In this case, the energy comes from reduction and oxidation reactions eating into the electrodes, which are made of two different metals – usually copper and zinc. The same effect was thought to lie behind claims that connecting electrodes driven into a tree trunk and the ground nearby can provide a current. But last year Andreas Mershin's team at MIT showed that using electrodes made of the same metal also gives a current, meaning another effect must be at work. Mershin thinks the electricity derives from a difference in pH between the tree and the soil, a chemical imbalance maintained by the tree's metabolic processes.

If this is the future of cellphones I will spend the future laughing my ass off

Bluetooth Concept turns your finger phone into reality � Coolest Gadgets
For those of you who are sick of the convenience of Bluetooth earpieces and want to live your dream of talking to your fingers like pretend phone from your childhood should look into this concept device. Designed by BCK, a team from Argentina, its a very simple concept. The user talks to the hand using the yellow ring that fits halfway down the little finger, and then listens with the pink ring on the thumb. (Why is the thumb look like its been drawn on the picture?) This is one concept that probably won’t catch on, ever. Unless you can make a display to put on the palm. Maybe there is some alternate reality where this technology came into fruition. Enjoy this poem after the jump.

Silver polymer reflector makes concentrated solar 25 percent cheaper

Breakthrough Makes Solar Power More Affordable - Denver News Story - KMGH Denver
A technological breakthrough may make what's called concentrated solar more affordable. The concept behind concentrated solar was to use large panels of curved glass to focus the sun's energy on a tube filled with oil. The heated oil is then used to make steam which powers a turbine and eventually creates electricity. Senior scientist Gary Jorgensen from the National Renewable Energy Laboratory said using glass just isn't practical. "They have problems with their weight and their cost. That's been the problem with renewables all along over the years is the cost hasn't been able to compete with the fossil fuels," said Jorgensen. He said a new metal reflector he helped create with a silver polymer will make the technology much lighter and cheaper. "That translates into, in terms of installed field cost, of a reduction of about 25 percent, which is an amazing reduction," he said.
