I spotted this here, and thought the following (don’t all, please, get killed in the rush…)
There is intrinsically nothing wrong with the idea of people installing wind turbines on a small scale if they want to, and if some idiot’s prepared to go to the trouble of fabricating the monstrosities for them. The concept that the wind is (sort of) free for the taking is an old one, and successful nations have risen and prospered, such as the Dutch, by using the stuff on a large scale by pre-medieval standards.
But to pretend that the electric power requirements, at high Amperage all the time and everywhere, of a large First-World Economy, including stuff like Aluminium-smelting-works and steel-foundries, can be thus provided by such machines, is flim-flammery.
Private wind-turbines are toys. There is no need for them to have expensive electronic nonsense, designed for “load regulation” or whatever, if they are not connected to the Grid. The people who will want them will be rich: therefore they should be connected via old car-alternator-rectifiers (about 40 sets in parallel is a good start for safety reasons) to stacks of lead-acid scrap batteries in the cellar: about two tons of the same, say about 120 batteries, will do for an average 2kW turbine. Good new car batteries can be had for about £2 each at any local Soviet mobile home park for Travelling People.
No wind? No charge.
You will be able to run an average _/House In Notting Hill/_ with five bedrooms, two kitchens with AGAs, nine laptops for the three children and five for the parents and nanny, plus the XBox and two “Wii” thingies, for at least four hours on a full charge of two tons of six-year old batteries.
Get some geek to build you a 12v=/230V^, DC/AC inverter using about 100 scrap power MosFets and transformers from old laptop adapters, and you are home and dry. Any amount of these can be had for under £1 each from your local computer repair shop, just like gunpowder was from your ironmonger in the 1950s. If the assembly catches fire, simply let him build you another one.
