1. if surprising - try to repeat

here is a repeated experience that I can repeat and others is valuable... and fakes the Internet is full of news, on their creation works army flooding on salaries.
2. is, even where something was discussed. But this is always home-made something is limited or the skills and equipment is not for the novice, or will be noisy and so on.
In most cases, really clean electrical schematic (without mechanics, electrolytic generators, etc.) do not ever give the usual 220 and all the classic current. Warm, shining and so on - will. But it will be cold and it has a number of fundamental features.
The easiest way to return him to familiar to us, and in fact, the curve 220 is to turn them with the motor generator on the shaft - again the noise is expensive and not convenient.
Therefore, all these twitches should have a good meaning. Just a cheap economy so not to. Assembly and debugging will require some money and hassle. For most therefore, this is not advisable.
By the way, most modern electric vehicles like Nissan and Tesla contain a hidden source. They only have a beacon, propulsion system and battery the buyer does not belong Paisano service only in the corporate centre and so on.
And so there's just the balance does not add up input and output.
Count how many pass good, especially lightweight hybrid like Toyota-Prius on one battery and how many will pass the same Tesla. And then ask how much she eats from charging kilowatt hours and how much weight (compared to the Prius, where all lightweight).
Tesla will not live to see, and Nissan, electric, RUSNANO last year saw a heavy full-fledged sedan. charging for 8 hours, consumes 3 kW (24 kW hours =full charge).
mileage IMHO is declared about 300 or 250. Called don't make me laugh....
So the question is not how, but it is advantageous if, before the lot was relatively easy to do on the knee. Now a little more time - any piece production, by definition, expensive.<
