Body
InfoHere I am, back again.I have not done it with my RVsI have a 90 lb flywheel from a marine diesel engine, set in good bearings on a 1" shaft (25mm,) in a sturdy steel angle iron frame, able to take any number and size of motors and generators attached with ve belts, and pulleys.I also have a complete inventory of different sizes of pulleys and belts.So far, I have had no joy.I have not given up, it is stored in a distant barn, and needs to be moved closer to where there is heat, light, and electricity.I see a lot of devices of this kind that people have put a lot of time and effort into. They seem to work.I just can't imagine all that for the revenue from some damn you tube video.Does anybody know if frauds get lost of bucks faking you tube energy videos? Then why are they there? Fame?Beats me! A lot of bother for what?Now about RVs from only my experience I put in 1.5 amps of 12 volt DCRun it through an inverterDrive the RV to speed of 1800 rpmThen open the shunt switch on the capacitor tuning circuit that then put a 120 volt to 12 volt transformer in series with the capacitors.I then rectified that AC and then ran a DC load at 2.5 amps DC measured at the brushes.It was an electric trolling motor for a small boat.I also ran a Rene charger off the transformer"s 20 volt multi tap winding, at no measurable amperage load at the battery.One is able to charge at least 10 batterys at once with no extra load on the Rene draw.You only get 1/3 the rated hp from the shaft of an RV as far as I know.Cheers WarrenSent from Yahoo Mail on Android

Guys I'll explain my idea. I'm building a power generator so I can get
off the national grid, because in Italy they are thieves. The system
is that of Chas Campbell, a large flywheel of 2 meters in diameter
(about 7 feet) weighing about 550 pounds that is rotated by this 5.5
horsepower engine in a rotoverter way, and the wheel will turn a 8kwa
three-phase alternator (11kw but effective 8kwa). Only I would like to
connect everything with straps to turn the wheel, and not in a jerked
way, but continued. Have any of you already tried to do it?
