If you have a gernerator that can make 12volts with 10amps at 100rpm. And you have a 8volt motor that needs 1amp to run, at 100rpm, you will have enough left over to charge a battery.


No, you won't.

I'll say it again. A generator transforms mechanical energy into electrical energy, with losses. A motor is the converse.

If you have a generator that can make 12V at 10A, fine. It will require 120W of mechanical energy input to do so, even if it is 100% efficient, which it isn't. Divide that by about 760 to get horsepower if you like mechanical energy that way instead of Watts.

You can't just think of RPM. The power level of a rotating system is a product of torque and angular velocity. In other words, it's not just the RPM, it's the torque at that RPM as well. A generator is going to reflect a mechanical load back to its driver. If I put a 120W load on a generator, it's going to require a certain level of torque as well as that RPM number. If I take off the electrical load, it will take less torque to rotate it at 100RPM. The generator's electrical load dictates the torque requirement the motor sees.

The bigger the electrical load, the harder it is to turn the generator. Even if it is a perfect generator, 100 percent efficient, it will still take 120W of mechanical power input if I am requiring 120W of electrical power out.

The motor is the same. In order to get 120W of mechanical power output, I have to put in 120W of electrical power, plus some for losses. The mechanical power output from the motor is a product of ..you guessed it..RPM and torque. A wussy little motor may indeed rotate at 100RPM, with no load. But in order to get 120W of mechanical power output, I have to put in more than 120W of electrical power.

Back to your idea, you can see that if it takes 120W of RPMxtorque to get the generator to put out 120W of electrical power, and it takes 120W of electrical power to get the motor to put out 120W of RPMxtorque, even if you have a perfect system with 100% efficiency all around, it is just a sorry sort of flywheel. With normal losses, it will immediately spin down and stop.

Yes so it does seem the hopes are fadeing fast. Most unforchant
Although if it means anything the figuers on the web page of the inventer are still increasing.
For those interested look
hear


Well interestingly enough Tom Bearden is not objecting to their word choice ( scientific description) so maybe i was just a little hasty.

peswiki.com...:LRP:A_Proposed_Proof_of_an_Overunity_Asymmetric_System_to_be_Tested

I am still busy reading Bearden's book and as far as i know it's the best on topic and it arrived at my door , on request, without it costing me a cent ( well that was more than two years ago) and if someone isn't asking you money for their scientific insight that is imo a great start.

There is more then one possible sorce for cheap abundant energy. The one that was talked about at the start of this thred is still be worked on, and they are in the prosess of selecting there experts to review it. But another possible sore is Zinc air fuel cells, hear is some information that I have found.

Zero emissions
Suitable for indoor use
Non-fossil fuel sourced
Inexpensive to produce
Purchased at retail outlets
Metal Slurry
Low Fuel Cell Production Costs
No Storage or Siting Restrictions
No Shipping or Distribution Restrictions
No Fire / Explosive Hazard

advertisment web page

The companies home page give a little better information. They have patents that exspire in 2015 and 2016 so these devieces should be on the market now I just can say that I have seen any. Hear is some of what is on the home page.

There is a better way to provide clean, quiet, reliable power. To provide backup and emergency power. To deliver the power needed at remote locations. To make clean, quiet, emissions-free transportation economically viable. To reduce our dependence on fossil fuels today.

Power Air Corporation (“PAC”), a clean energy company, has now made this better way possible by developing a commercially viable Zinc-Air Fuel Cell ("ZAFC") technology that generates reliable, environmentally sustainable, zero emission energy for portable, stationary, light mobility, and transportation applications


I think it is great that many people want to change the sorce of the energy that we use. I just have yet to really see a big difference hapening. Am still hopefull though.
