SAN FRANCISCO – A former employee of SpaceX has set a very ambitious goal of building a working solution for humanity’s ever-growing need for electricity. No bigger than a regular container, his invention is a nuclear fission reactor generator. Portable, affordable, and economically feasible, the power plant can be deployed everywhere.

In an interview for Interesting Engineering, the head of Radiant Nuclear (the company that builds the reactor) shed light on his work.

Doug Bernauer, CEO of Radiant Nuclear and ex-SpaceX engineer, got the idea from a project he worked on while at SpaceX: supplying power to a human colony on Mars. The challenge was that it had to sustain the facilities on the ground and refuel spaceships that could travel back and forth between Earth and the Red Planet. Since the Sun was not a good enough solution, nuclear energy came up.

But, until humankind reaches that stage, we can successfully use that invention on our Blue Planet. With $10 in million funding from Union Square Ventures, Radiant Nuclear is on its way to building the world’s first portable, zero-emissions power source. The prototype could begin the testing stage in five years.
