Using Slow River Currents to Generate Power

Scientists have found a very promising and clean source for energy that uses the slow movement of the currents under the rivers, oceans and streams to generate power. The new device, which has been inspired by the way fish swim, consists of a system of cylinders positioned horizontal to the water flow and attached to springs. As water flows past, the cylinder creates vortices, which push and pull the cylinder up and down. The mechanical energy in the vibrations is then converted into electricity. Read More.

Data loggers can provide valuable information for nearly every aspect and scale of green design. For example, a facilities manager can monitor temperature in a fifteen-story office building over the summer to check whether the fans in the building's cooling tower need adjustment.


Our core activity is a series of annual regional business plan competitions for cleantech startups looking for a jump-start in bringing their products to market.


Basically, Pigouvian taxes would tax the things we do not want in our society, like toxins and greenhouse gases, and NOT tax things we like in society, like employment and housing. For example, when coal power plants emit traces of mercury, we should not tax the power produced, but the harmful mercury emitted.
