Western University engineer Louis Michaud has received an investment of $300,000 for a start-up company that aims to harness energy from controlled tornadoes created for this purpose. A single twister-generator machine could produce as much energy as a coal-fired power plant without the downside of greenhouse gas emissions.

Michaud has successfully proven the Atmospheric Vortex Engine idea using a 13-foot diameter version and is now working with Lambton College in Ontario on a 26-foot-wide-by-20-foot-tall outdoor prototype that will create tornadoes up to 1.6-feet wide and 164-feet tall.
