The Hydrobee: USB Power from Nature

Energy Inventions | Human Power | Hydro PowerWe just received an email from a company called Hydrobee, asking us to vote for them as Autodesk’s inventor of the Year. Having never heard of this we checked it out… what a neat invention! This soda-can sized device generates electricity for USB devices when you’re off the grid. It can generate power using flowing […]

Dutch children learn about life and death through lion dissection

Until today, the most peculiar thing I’d heard about Denmark was that parents leave their children to sleep outside in subzero temperatures — something that would get you arrested in the United States, if not put on a government watch list.

Afterward, the zoo held a dissection, invited the public to watch the process, and then fed Marius the giraffe to some nearby lions. The world hates little more than an animal meeting its untimely death, and an outpouring of outrage…

New approaches for hybrid solar cells

Using a new procedure researchers can now produce extremely thin and robust, yet highly porous semiconductor layers. A very promising material — for small, lightweight, flexible solar cells, for example, or electrodes improving the performance of rechargeable batteries.
