EM space drive

Not necessarily -- the thrust would be continuous so the craft would be accelerating - rather than a craft coasting after a burst of fuel, and carrying the fuel needed to decelerate at the end of the voyage.Enjoy

True, but that also adds to the mass that needs to be launched and accelerated. Of course a ship could be assembled in space to take care of the launch problem, and it could carry a lander as was used on the moon mission so that the lander wouldn't need to be large.You could also set up a colony in orbit or on one of the moons first. Step by step.Enjoy

Wouldn't a large magnetic field do the trick? The earth's magnetic field is not that strong, and solar power into a coil the length of the ship should be able to form a similar field in the surrounding space.Enjoy

oh, so you're going to play the role of anti-EM?(ducks)Edited by RAZD, : urled

Once I saw how easy and accurate the lasers were I went out and got my own. It has been a big help in renovating an old house - establishing real vertical walls and the level of the floors.I'm sure they were well laid out when originally built, and that the people that took two old buildings (one 1795ish the other 1860ish, moved them to this site and added a fourth corner (sometime after 1895) did the best they could, but there was still over a hundred years of wear, some questionable remodeling, and settling to deal with.Such fun.EnjoyEdited by RAZD, : ...
