I was strolling the web when I ran across this link to a very interesting video about building a micro wind generator. This is a very interesting concept that could, because of cost and ease of construction, put wind energy into a great many hands that could not afford or maintain turbine generators. Larger applications would most likely require a few different materials, namely the belt, but the concept is still very exciting.

This article over at PhysOrg has some very interesting implications. Sony has managed to develop a process for producing bio-batteries. These batteries produce electricity by breaking down sugars. At this point, they are able to produce about 50mW of power, the highest yet achieved by bio-batteries. This comes as a result of Sony’s work on an improved and efficient process for breaking down the sugars. (more…)

Have you ever wondered what renewable technologies provide a net energy gain? There is so much politicized talk about whether certain renewable sources are viable because of the energy consumed in their creation, such as ethanol. This got me to thinking … surely someone out there has done research on the net gain/loss of these technologies and published the findings. With a little bit of looking, I found several places on the web providing Energy Returned On Energy Invested (EROEI) study results. I rather liked this chart over at (more…)

America. Dreamer of dreams, worker of wonders. Here is your next great challenge. You must end your dependence on fossil fuels. You must do it now. It has gone beyond an economic issue, beyond a political issue, beyond a national security issue. (more…)
