High altitude wind power harnessing not as efficient as previously though

By Damir Beciri
One Comment16 December 2011

rotary-wind-turbine-kiteThe high winds were thought to be a rich potential source of renewable energy, however, a study by researchers from the Max Planck Institute for Biogeochemistry in Jena, Germany, shows that the near absence of friction and absence of strong propulsion cause the jet streams that sweep the upper atmosphere to harness about 200 times… »

osu-microchannel-heat-exchangersEngineers at Oregon State University (OSU) have made a major step toward addressing one of the leading problems in energy use  around the world today – the waste of half or more of the energy produced by cars, factories and power plants. They have built a prototype which captures and uses the low-to-medium grade waste… »

miniature-generatorThere are many power sources today as wind power, hydro-power, tidal, geothermal, solar power as well as the power used in wristwatches, where oscillations that occur while we move our hand power the watch. Researchers from the University of Michigan are developing a similar, more sensitive, technology. Their small generators could produce enough electricity from… »

Biosolar hydrogen production with green algae

By Damir Beciri
1 October 2009

green_algae_chlamydomanas_reinhardtiiA fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. In order to produce energy, fuel cells use oxygen and hydrogen. Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. It’s also the most plentiful known element in the universe. Despite its simplicity and abundance,… »

wind turbineClean, renewable energy is freely available – in the form of wind, sun, water and potential other forms we haven’t discovered yet. However, harnessing the energy with reliability and in a cost-effective manner remains a barrier. Wind power is one of the fastest growing alternative energy markets and researchers all over the world are developing… »

Biomimicry of heliotropic plants – more efficient solar panels

By Damir Beciri
6 Comments30 May 2009

sunflowerslg005.jpgMany plants are heliotropic, gradually tilting towards the sun to optimize solar energy capture. Current sun-tracking solar panels involve the use of motors and electronic control systems, but we believe a biomimetic heliotropic solar panel can be created with the use of alternative materials and designs. Practically, the heliotropic solar panel could be useful in… »
