Can Microwaves be used to heat the air around it or something else? To
use a field effect and no longer need to use old style combustion?

all the space vehicles today depend on combustion tech for launching

gives just enough thrust to take a space vehicle from the earth surface
to the space against the gravity. now the speed and fuel capacityof
these vehicles will not be enough for long space missions ....so is
there a way by which we can use an alternate technology to launch space
vehicles without using combustion technology ...is there a way to over
come or anull the gravitational forces and make a body levitate ....?
