Unfortunately history has examples, Greenland Norse, Easter Island, 
and Mayans where things fairly well went down the drain.  I happen to 
be an engineer who is used to being given a problem and marching 
orders to solve it.  But there are problems, backwards time travel 
and FTL travel that are probably in the "can't be done" 
category.  Others such as diverting an asteroid collision on short 
notice can't be done if we don't have enough time.

But the energy problem is one I think could be solved without massive 
population collapse *if* we get started quickly.  SPS on a crash 
program, under ten years, is a solution that's been understood for 40 
years now.  There may well be other ways, a vast scale up of nuclear 
power of a new design, the pebble bed reactors, might to it for long 
enough to reach some kind of singularity where we or our machine 
offspring or some combination get smart enough to get more power or 
run on less.

You may be right.

It's impossible to get as much performance out of batteries as you 
can get out of hydrocarbons.  If you think of them in battery terms, 
65% of the battery come out of the air and you don't have to carry 
it.  Trucks on batteries?  Not likely.  Trains can be 
electrified.  Aircraft are being taken out of service by the 
thousands because of high fuel cost.

You can make liquid fuels from electric power.  It just takes a lot 
and then the problem is where do you get the electric power?

A lot of them don't scale up.  That was the point of the exposition 
on converting trash to oil, there just isn't enough trash.  There 
isn't enough land do grow bio fuels.  The storage and transmission 
problems are extremely hard to solve on solar power from deserts.

True.  For some bizarre reason the Norse didn't fish (you can see 
this in the isotope levels of their bones).

For all with an interest, I suggest going here 
http://www.inference.phy.cam.ac.uk/mackay/README.html

and take the link to his book.  He knows the physics of energy.
