New? Pfffft! This concept has been on the books for decades. Looks like another laboratory experiment that won’t scale to the power and propellant load requirements of an actual vehicle. I’m also wondering how safe this will be to test on the ISS. I’ll bet the safety folks have not reviewed the requirements for this yet either.

Such details seem lost on some folks. But dont point that out though or you are ‘anti-space exploration’ yada yada yada.
