Ergenics Hot Water Heat Engine Demonstration

Video shows two buckets of water -- one hot, the other cold. As the two heat exchangers from the Ergenics apparatus are immersed into the two buckets, the temperature differential drives a turbine, powering a generator that powers the light.

Ergenics is developing a metal hydride heat engine that converts the energy from hot liquid (e.g. solar hot water) into electricity for an estimated cost of about 1¢ per kilowatt hour. For example, solar panels produce hot water which is pumped to a hydrogen compressor that compresses a gas that is then expanded in a hydraulic motor-generator set that produces electricity.

The technology has a multitude of other applications and iterations. Please see www.ergenics.com

that is really cool what was the temp a guess if you dont know for sure of the hot and the cold water?

[Ergenics]

In the above video the hot water started out at about 90C and drops down to about 75C. The cold water starts out at about 15C and heats up to about 30C

if you can .. could you mail me something like.. a scheme or soething .. i want to take a closer look at it ..

[Ergenics]

We have one on our web site. Go to ergenics. com then click on "Heat Engines" then click on "Solar Electric".

are you able to isolate the poles from each other - does the ambient water gain heat?

[Ergenics]

Yes, the heat exchangers can be configured in almost any way, and yes, the cold water is needed to reject the low temperature heat of the heat engine. In actual practice this heat would be removed via a fluid-to-air heat exchanger to the ambient air.

...over the revolver chambers and locked in another piece of foam(normal temperature and no expansion or contraction) in the hot rod chamber and in the cold rod chamber(The first mini chamber was empty in the cold rod chamber,so the foam would not contract over the piece of iron and pull it downwards the same time as the hot foam pushed it upwards),The cold foam pulled the piece of iron downwards producing momentum again,and so it rolled on.

I made it,

I made a rod go up and down.haha

[Ozoltani]

I made a similar "heat engine" at my faculty( a rod producing momentum lol) which kind of powered itself,2 high Cp wires which led to the upper part of the "machine" guiding temperature diferential from both buckets there,on top of each wire was something similar to a revolver chamber which held 6 mini chambers containing foam which expanded and contracted greatly on temperature change,the warm rod heated the foam which lifted a piece of Austenite iron upwards which made momentum...

ok so that was 4 years ago, you guys should be millionaires now, is that true?

[randommagnum]

So, if I understand this so far (correct me if I'm wrong) you need to keep reversing that to make it work; it doesn't circulate...right?

It's still a good idea. You could set up some kind of gas analog to a rectifier, using check valves like diodes.  Rig up something to keep it going back and forth between cold and hot...and you're in business!

I think this is brilliant. Easy to see that it will work to make energy very cheap.

It makes great use of solar heated water to move a piston via hydrogen expansion. During the winter, you could obtain both cold water (water cooled outside) & hot water (water heated via solar) to make clean energy at little cost.

Free energy is finaly here!But some very powerfull ppl don't want you and me to be free from energy costs,Get a REAL working magnet motor at LT-MAGNET-MOTORdotCOM ,Start the energy revolution!

[fairyheli2]

what happens when all the hydrogen flows from one side to the other?

[skittlesmonkey]

using a coolant like freon would be counterproductive sine u want something with a low heat of vaporization ( a coolant is designed to have a high heat of vaporization)
