Moped Generator... reconstructed....

Well, it seems you might be onto something here.

1 HP is directly converted to 745.699872 watts

If you are only using 1/2 hp to get 600 Watts, then you are definitely over unity.

What we need now is a step-by-step tutorial so that someone can do an independent confirmation.

Peer review is invaluable. We need to exclude measurement error. Alexander Graham Bell discovered the telephone becuase he screamed in pain after a lab accident.

Legendre, did you see my post about the portable generator?

This is a fun one for you, where the rated HP of the small desiel engine is 9 HP. Thats OK, but then wait a minute.. they say the electrical output power of the generator is 7500 watts! now what's up with that I wonder?? Maybe you can have a look at it yourself and tease the California manufacturer about it. There must be a serious misprint there right?

Thanks for your comments and all the best,

pg46,

Ok, since you're obviously interested in this, here is the explanation for the 7500W rating on the 9HP generator (the key to this is the surge rating):

9HP is equal to about 6700W, which is in line with the continuous rated output of this generator - 6500W claimed. Ok, so far no overunity - average power output is rougly equal to average power input, with some losses.

What you aren't considering, is that most all devices which supply or consume power (in this case, engines and dynamos) have multiple ratings; continuous, surge, design maxiumum, do not exceed, etc. The fact is, both the engine and the dynamo in this generator have surge ratings that exceed the continuous rating. There is nothing special about this, just reasonable design. In fact, a 7500W surge from a 6500W rated generator is about right - 15% or so above continuous.

Also, since we were discussing flywheels, let's not forget to include them as well. The engine crankshaft and dynamo rotor work together as a large flywheel. Flywheels work like this: If 10HP can spin the flywheel to a given speed in 10 seconds, and you then put the flywheel to work so that it stops in 5 seconds, it will perform an average of 20HP of work over that 5 seconds - more at first, less at the end; twice the power over half the time. In the end, the same amount of work (minus losses).

Hope that is of use. Cheers!

Hi Legendre-

As to not hijack this thread I will reply to you over at http://www.overunity.com/index.php/topic,1497.0.html
-the overunity portable generator thread.

Meanwhile I hope Frost will be able to provide better or at least clearer tests while 'under load' with his Vespa generator. That will be very helpful and we won't all have to run out and buy old vespas and rebuild their generators 

Best,

The main thing here is that the moped generator is a reversed generator. in the sense that the magnets are around the coils, where a "normal" generator found in a car and small porteble generators. the 500w flywheel has bigger magnets than the 200W, that is the only diference. the first time i mounted the 500w flywheel in the engine i almoust destroyed it, the magnets have a pulling force of aproxx 6 kgs A PIECE!!. and it was almoust imposseble to turn the flywheel by hand. but when the engine was started it had no problem with standing idle even after i tryed short circuting the power coil. normaly when you do that on a genertor or a electric engine it really pulls power from the shaft. the 500w flywheel had no problem allmoust fully lighting a 250w bulb in idle. the moped did suffer a little due to the pulling force to the coils iron. topspeed only dropped max 5km/t. the acc was a little bit slower. the only limiter now is the copper thickness in the coils. im am currenty working on a much better thing than this generator. but this generator is worth some loking in time for you out there that likes to mess around with generators. i won?t be posting so much in the future but when i complete the next project you all vil get it. the next thing is "the mechanicel magnet engine" a pure overunity no fuel engine. and on this topic: any moped generator will do, be it puch, vespa or any scooter or Moterbike ign.
