While much fuss is made over the possibility of EM-Drive, there are actually two propellant-less, low trust concepts being evaluated. Cannae has similar properties, but depends on superconductors to operate. There are plans to do a demonstration satellite in the next few years.
In the near term, these rockets could make extensive surveys of the asteroid belt and outer solar system possible for light spacecraft. They would provide another strong incentive to build space-rated nuclear reactors. Finally, we could get beautiful images of the planets around the Alpha/Proxima Centari system - by flying a probe in the exact opposite direction.
This newly-discovered ice field is half-way between the north pole and the equator. It contains as much water as Lake Superior, and covers an area the size of New Mexico. It is between one and ten meters below the surface - very easy to reach by drilling or excavation by future Mars colonists.Continue Reading
The MacroInvent site is being updated

The internal deadline to finalize the professional layout is December 15. After that, some of the more advanced services will be turned on as they are developed.
Let me teach you how to invent, to disrupt, to accelerate.
