There are worse things you could be doing than watching the following vids.... I quess they are or were a youtube hit, doesn't mean much to me if they are, I only care if info is accurate or thought provoking and the BS level is low. the first vid is just something for the NYTimes they did as a intro. Having watched most there vids I can sum up the main points.....forget your big hummer BOV, to get around in a war zone you want a bike, or motor bike, but mostly a petal bike as it wont get comandered...that says civilian/non combatant....forget your camo, flak jacket and AR unless your looking to engage...a t shirt and bike lets you move around a war zone.
They were Appliance repair men and they said they had lots of work when the war broke out, in fact they could be busy, doing well, repairing stuff in the middle of the war but they earn more doing youtube vids that they now make.

How they made power
https://www.youtube.com/watch?v=AfrvxtgY8yY

Note when he is on the bike the meters show 12.4 volts and 5.2 amps and he is saying that's easy (64 watts).....true if your maybe 21 years old, in the real world, for the average person, 40 watts is all you will really be able to do into batteries without busting a gut over time., But that's not chicken feed, 40 watts could keep a lap top running for a hour, power a couple 7 watt leds, and charge a couple cell phones. I have found 40 watts to be the measure of what can be put into batts over time with mussel power . If someone tells you different make them prove it.

anyway they have other vids if your interested
