there are posts about this very topic. Yes, the only true reason for an engine is escape velocity.....motion to direct the craft, and motion to slow
Once we have a better grasp on solar wind theory moving out into the galaxy and beyond will prove much more reliable. Cheaper too.
Solar wind is created as the sun gives off heat. If we put a craft with a large sail above the gravitational pull that would return it to earth. All
it takes is a small thrust to initiate the motion. (Like a hot air balloon rises, the expanding heat from the sun continues to produce thrust.)
Don't get excited yet. You still have to have some way of directing your path. And the initial motion is not going to get you very far at the outset.
Here's the great part.
We know that all orbiting bodies have a gravitational pull. That pull doesn't just disappear.
But at a certain point between all orbiting bodies there is a point where gravitational pull equals keeping everything in place. (This is why you
don't wake up and find the moon landed in Omaha.)
It gets better. Once we have our craft moving and directed to our destination, we are going to penetrate this dead zone. It might take three days to
get there by solar wind alone, but once we do the gravitational pull of the destination takes over!
So now we've got gravitational pull and solar wind moving us toward where ever we want to go!
Two froms of propulsion must be better than one when one is pushing and the other pulling. So our speed dramatically increases!
This leaves all our fuel for retro firing to decelerate.
Make any sense?
BTW, E=MC squared confuses me.
C= maximum constant speed in the formula.
Do you see the problem?
If we obtain the MAXIMUM CONSTANT speed, how do you SQUARE the maximum?
If you can square it, it's not the maximum, is it?
