Solar Powered Stirling Engine

20 05 2009


Given the rise, in recent years, of liquid fuel prices and concerns such as peak oil and climate change, it is no wonder there has been a tremendous interest on new ways to produce energy. Today we would like to share one that we have found out about: Stirling Engines.

A Stirling engine is a device that converts heat energy into mechanical power by alternately compressing and expanding a fixed quantity of air or other gas (the working fluid) at different temperatures.

Bioelectricity as the new alternative to Ethanol

8 05 2009

Due to awareness on the scarcity of fossil fuels and increased media coverage regarding global warming, alternatives such as Biofuels have gained an increased attention worldwide. However, researchers writing in the online edition of the May 7 Science magazine have now come to the conclusion that using ethanol to fuel our cars might not be the best idea after all.

Since growing energy crops are likely to compete with food crops for fertile ground, which would lead to the clearance of more forests to increase farmland, the researchers claim to have found a better alternative: convert biomass to electricity rather than ethanol.

Example of a “blogger” plant, where its bioelectrical signals are used to issue posts at a blog in Japan
