Good point ;-) But as all was below 12V and earth-free, I could have risked it this time... >There are some guys which are building such devices in (small) series, trying >even to sell it. They're assembling it when ordered, shipping 40 days after purchase. The ebay user comments mention lots of russian tubes, valves and spare parts that were sold correctly, but it looks like they have never sold such a generator before. I think it's curious that they're talking about battery capacity in the product text. If the machine produces 1kw, there is an optimum capacity for that, no point in increasing it. Why would you need backup for a device that does not need any fuel? On the wikipedia page, there's a plausible explanation: The machine drains the batteries, but uses a trick to make the batteries still appear to be full. > There is a movie sowing what they do with back > EMF:http://cgi.ebay.com/FREE-ENERGY-FUELLES-GENERATOR-1-Kwt-AVIG-XXI-century-/250713195287?pt=BI_Generators&hash=item3a5fabc317#ht_9354wt_1135 They only show a big rotor with an obviously good bearing, some sine waves at about 180 Volts (not the 220V they try to sell), lots of wires and lead-acid batteries... That's unfortunately not enough to convince me :-D While Seb uses his motors as generators, they build a motor and call it a generator. In both cases there is both a voltage and a frequency by which the rotational speed can be determined. The frequency would be the more accurate in either way. So we're back on topic. ;-) Greets, Kiste -- You received this message because you are subscribed to the Google Groups "jallib" group. To post to this group, send email to [email protected].
