Tunnel Boring Machines (2018)
I know this is probably a very stupid idea, but I was thinking what if we shot ourselves out of rail guns into the air into a bullet shaped craft with fins?<p>You could be shot out of one rail gun in San Francisco, glide for awhile, fall to the earth and caught by a “reverse” railgun in San Jose.<p>It'd be cheaper and safer than planes since no need to carry fuel or an engine on board, and could have an emergency parachute incase something went wrong.<p>Or maybe I've been dreaming about Kerbal Space Program projects too much lately. (I'm fully expecting to be flamed and jided for this)
