Swedish Research Project Proposes Electric Car Batteries… Made of Wood?

by Gage Taylor

These days, it seems rare that a week passes where we don’t hear about some new kind of exotic or outlandish approach to electric car construction. With technology moving at a breakneck pace and interest in the field at an all-time high, concerns over range, power delivery, and cost are to be expected. But where most announcements seem to revolve around nanotechnology or other synthetic materials, a team of researchers from the KTH Royal Institute of Technology in Sweden announced this week that they’d constructed a small-scale model of an electric vehicle battery pack made from wood. By developing a new carbon-fiber material which has lignin, a natural polymer found in nearly every dry-land plant on earth, as its main ingredient, they’ve made a big step toward cheaper, more energy-dense batteries.

CorPower’s Recent Breakthrough in Wave Energy Technology

by Melanie Paty

In a recent article posted on KTH, the Swedish Royal Institute of Technology, Peter Larsson reports on the wave energy technology breakthrough of CorPower. Ocean Wave energy technology has been limited by its cost, but CorPower Ocean, a Swedish company, has designed a gearbox system that generates four times more energy than competing systems at one third of the cost. The CorPower converter, developed in collaboration with KTH researchers, is a point absorber system, using a bobbing buoy to turn gears that drive the generator below the surface. Continue reading
