Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Hi Jason,

I would be interested in your switch. Please email me: gotoluc2@gmail.com when you have them available.

Thanks

Luc

Take a look at this thread


http://www.control.com/thread/1307586278

The general opinion amongst this group (with no connection to SERPS or any other energy saving focus), is on a distributed power generation system, there is no reduction in prime move fuel comsumption due to a reactive load due to the extra losses though the transmission system which are in proportion to the square of the current and reduction in generator efficiency when running at a PF below 0.8
The real losses are due to the increased current in the transmission line in both directions.

I think this post is more typical of the general opinion there.

And of course logic tells us that ie. if I wanted to power an inductive load with an output power of 1 kW and the
power factor is 0.5 then I would need a generator with over 2 KVA rating, but if the load has a power factor of 1.0
then I would only need a little over 1 kW rating, this is an increased expense to begin with, then the current portion
of the VAR cause losses in the line resistance ect. as stated below. We should imagine a reactive device as if we
intend to power it ourselves with our own generator of AC.

Just imagine having to fuel a 5 Kw generator to get a power output of 1 kW in a bad case scenario.

Even worse imagine the generators they would need if every household ran at a power factor of 0.1. That would not
be sustainable for the energy companies and so they would have no choice but to charge for reactive power or factor
the cost of the reactive power production losses and increased overheads into the power bills, maybe with a rebate if
you show a good power factor. The worse your power factor the more you should wear the costs of it, that's fair.

QuotePrasad: remember, current does not "contain" MW.

Watts are produced when current flows thru a resistance and all generators, bus work, transformers etc have some unless they are superconducting. So when current flows thru a resistance, watts are produced in the form of heat in an amount equal to I-squared-R. Those watts dissipate energy which must have come from somewhere. In this case, "somewhere" is your generator which converted mechanical energy into electrical energy. Your generator received the mechanical energy from the conversion of thermal energy in your turbine, therefore the turbine must have burned more fuel. So increased reactive power generation increases fuel consumption.

The law of conservation of energy always applies
