Despite its other environmental impacts, including toxic waste that requires centuries or millennia of storage in facilities designed to protect future generations from the genetic and acute effects of radiation, nuclear power is considered by some influential environmentalists an essential component of the post-fossil fuel economy.

Meet Jay Yu, founder, executive chairman, and president of Nano Nuclear Energy Inc., and James Walker, CEO of the company. Nano Nuclear develops smaller, portable nuclear microreactors that can be moved to where electricity is needed on a truck. These microreactors can generate between one and 20 megawatts of energy, enough electricity to power as few as 400 homes or up to 20,000 homes,…
