A new startup called ExRo Technologies has developed a new generator to harvest energy from wind, that could both lower the cost and increase the power output by up to 50%.

Their new generator can run efficiently in a wider range of conditions than current generations do, so that more than 90% of it’s energy can be converted to electricity. The problem with conventional generators is that the efficiency drops dramatically if the wind slows down or speeds up, but is compensed by a fuel-powered engine, which increases costs.

ExRo has managed to replace this mechanical engine with an electric on that can dramatically increase the range of wind speeds at which…
