You say you started without - how?
Even gliders seem to need tows.

Maybe he'll build an electric motor rope launch skid powered by
wind turbines.



Could do. There's lots of ways you can winch launch. The current
world record distance flight was launched off the back of a car.
Probably a thirty second tow, if that.

I doubt that this was an electric car charged from solar or wind
power,
was it? I'll bet it burned gasoline (or perhaps diesel fuel).

Point is, there's a million ways to skin a cat. If neceesity
dictated, a way would be found.

And your answer is?

Unless you have a better answer, I suggest folks start building
nuclear
power plants, and looking hard at extracting carbon from the
atmosphere to combine with hydrogen from water to produce various
petroleum fuels. We are not prepared to deal with hydrogen -- I can
just imagine the news stories about the result of accidents at
hydrogen fueling stations.


BTW, hydrogen is no real problem in regards to that. It can be used
safely in surface transport and fuelled safely as well. The real
problem with it is making it.

Making hydrogen is not a problem if you don't care about the cost.

The cost is getting pretty close to that of gasoline as it is, but
that's from hydrogen made from petroleum products, of course.

The engineering problem for wide spread use is hydrogen embrittlement.



What, from burning it in your engine or from manufacture?

From containing it.

Essentially the same problem as ethenol; existing plumbing won't
handle hydrogen, so if you want to distribute the stuff in anything
other than liquid hydrogen trucks, you need all new pipes designed
to carry hydrogen.
