And HL i agree. Take cars for example. There will be many around after an TSHTF but what happens when theres no more fuel or parts and they stop working. Could you make a car and the fuel to run it? Many years after we may be back close to where we are now, we also may never get back here, there are too many unknowns to know for sure, so we prepare as best we can and hope its enough.
@the first half, I was only using a computer as an example. And there are many other uses of that energy that I'd rather opt for (my wife is stunning, so I can think of many uses of lots of energy!!! haha) but the fact of the matter remains, the simple basic principle is there, all being well, you could have a working computer post SHTF. Uses of that computer...Educational DVD's and programs to teach you to rebuild society/batteries/farming/medical/generators/who-knows-what-else, mechanical vehicle maintenance, access to the files you've not printed out, etc.
As for the second part, you can use wood-gas to run a car, and I know I can produce wood-gas. So making it wouldn't be in issue. After a little trial and error, getting it into the engine block shouldn't be too much trouble either.
About the vehicle maintenance stuff, I'm going to be spending time at a few garages in the area to learn to change parts, maintain what's there, and trouble-shoot most issues, as well as diagnose the problem in the first place.
The skills we can guarantee that stay alive after TSHTF are those we have internalised fully.
