News out of NASA is that their tests of the EM drive space propulsion concept suggest it is a real effect.

Discussion centres around using a compact reactor as is used in nuclear submarines to enable spacecraft to reach the Moon in as little as 4 hours and Mars in 3 months.
One problem may be that the heat dissipation requirements cannot be met when there aren’t unlimited quantities of sea water to cool the reactor.
But a bunch of 20MW Focus Fusion reactors could offer an excellent power-to-weight ratio yet run very cool, not relying on a steam cycle to operate.
Maybe NASA would be interested in supporting the development of Focus Fusion?
Regardless, taken with the reports of faster-than-light transmission thru the device, I think I can safely say we are now living in the future! Exciting times!
