This was very well done, had a realistic feel to it with some nice cinematography. I liked how they didn't try to do anything flashy. The opening title screen with the electric effects were really nice and fitting too.
-
ok you are right...
-
Very well done guys! Great topic :):)
-
yeah but that is what the interviewed meant .. the people dont have to walk for long distances ok .. the USA would be a bad example because they do everything with the car... bad habbit guys
Dont know how the canadians are..
-
@theschnitter Of course ¬¬. You know what I mean.
-
but not walking from Spain to Germany just to visit a good Friend. If man walkes such a distance today then just as test for them selfs or make a pilgrimage. Not for the reason that theirs no other way to get that distance.

People still walk. Take a look to other parts of the world.

It's not my domain of expertise, although i did study internal combustion engines. But I think you're kind of downplaying the efficiency of the the engine. With new technologies I think they have yields of over 90%, because if they didn't have them by now the we would've switched to a different type of propulsion.
@NobleValerian - yeah but the problem is the conversion rate of photovoltaic cells. The Sun is a powerful fission reactor, but we have no way of capturing that energy, yet.

nice
-
hydrogen cars run at an efficiency of about 10%, while your regular gas car runs at around 25%. they need to improve the technology before it becomes feasible, and even then i doubt pumping all that water vapor into the air will be a good thing
WELL DONE, the set-up for this documentary is well laid out, and I give 5/5 for it. Bravo this should go onto BBC.

A source of green energy is a natural moving force which we take advantage of, how can that be inefficient?
