Best uses for space solar power

A quick brainstorm here.  It has occurred to me more than once that the most energy intensive thing you can do is to create kinetic energy.  That is why getting a rocket to orbit is so hard.  Kinetic energy is proportional to the square of the velocity.  Thus, to double one's speed will quadruple the energy requirement to do so.  To go 10 times faster requires 100 times more energy.  To go 17k mph...  And so on.

Another thing to keep in mind is that to convert energy from one form to another imposes losses.  For example, to change heat into electricity looses at least half of the energy.  All energy conversions are going to cost you something, maybe a lot.

Batteries work pretty well in that they can convert chemical energy to electrical energy in the 90% range.

With that in mind, let's say that you dedicate a space solar facility to transportation needs.  Beam the energy from space to separate charging stations on the ground.  The energy losses would be kept to a minimum because of the use of batteries.  You could have a lot of charging stations all around which may help with "range anxiety".  Space solar could beam energy to any place on the surface.  You don't have to truck large amounts of fuel across long distances.

Now, if you were to use space solar to make fuels, you lose in a number of ways.  First, in the creation of the fuel.  Then in its consumption.  By the time you get useful power out of it, you will have lost almost all of it.  Not efficient enough.

On the other hand, space solar requires one energy conversion to get the electricity and one more to store it and yet one more to use it.  However, each of these is fairly efficient.  You retain most of your energy.

Even with space solar, you lose a lot.  But by the time it gets to the ground, you can keep most of that.

Hmm.  A little more thinking on the subject yields another idea.  Beam the energy to highways which have recharging stations built into them.  That is, if you are on the highway, you pass a recharger that can zap a capacitor with enough energy for you to keep going continuously.  Perhaps it could be delivered to the capacitor by wireless technology.  Capacitors may be even more efficient than batteries.  But their range is short.  You make up for lack of range by continuous recharging.
