Having seen all the alternative energy posts here,
I just came across an interesting well illustrated online magazine
(Chinese wheelbarrows etc! as well as "gasbag" vehicles, solar power, pedal power with unusual takes...)
done by someone in Barcelona, Spain

also has section on eco-tech myths

Recycling animal and human dung for sustainable farming
Long article here:

Also with long articles and more illustrations, topic examples

"Wood gas cars were not the only answer to the limited supply of gasoline in World War One and Two....

....an even more cumbersome alternative came in the form of the gas bag vehicle.
The old-timers on these pictures are not moving furniture or an oversized load. What can be seen on the roof is the fuel tank of the vehicle - a balloon filled with uncompressed gas."

Solar power, use in factories, the concentation of solar power etc...


wind powered example (!)

pedal powered solutions

Thanks for the links, I'm enjoying the read.
I especially like the Lost Knowledge section.
Opportunity is missed by most people because it is dressed in overalls and looks like work - Edison. Tiny ad:
