Ergenics Small Powerful Hydride Heat Engine Demo

[gatraw]

btw metal hydride has been used to store hydrogen gas for a long time, the trick is making use of that energy, and it is more difficult to force hydrogen back into metal hydride

[gatraw]

how much force can the hydrogen expand against?

[mangyscavenger]

It would be incredibly easy to get an overbalance wheel going if this technology were used to instantly shift (reset) the weights. A Fresnel lens could be focused to shoot the weight to the axel.

Just a thought I had when I saw how much power was behind the piston. Maybe I'm wrong.

Would this work on a space satellite revolving around facing the sun as a heat source. then turn away into the shade to cool. Could this be a way to generate power.

[skittlesmonkey]

how does pressure affect the absorption of the hydrogen on the hydride? is it comparable to liquids ( that cannot exist at 0 pressure)?

[skittlesmonkey]

so the real advantage here lies in the low heat of vaporization ( sublimation ) of the hydrogen, making this thing much more efficient and this allows u to make much more gas per unit heat?

[fuelban]

very ,very intresting work you have here guy, very nice.

[Lubobuba]

This clip just made my day. How could I live my live until now without knowing the beauty of MHHP's?

Congratulations and my admirations on your work. Without any doubt, MHHP's technology will shape the future.

i want buy one ? how to do it?

[gilbondfac]

it's similar to a stirling motor .but you use helium gaz perhaps ?

[electrique527]

It is hydride. Hydrogen absorbed by a metal, and released when the temp gets up.

[pisoiorfan]

hi,

How many cycles the hydride can handle before losing significant capacity? If this is short, is there a simple way to "regenerate" the hydride?

[macrumpton]

Impressive! What is the temperature difference between the two water baths?

[Ergenics]

The temperature of the warm water in the above demo is about 45C. The temperature of the cold water is about 15C.

[rickm09]

@Ergenics isn't metal hydride highly restricted by govt

[alexkittybag]

how does this technology compare with stirling engine technology in terms of efficiency and power output etc?

[Ergenics]

Using a water heat source temp of 85C and a heat sink temp of 35C the heat to electric power conversion efficiency of our newest units is about 7%. We do not know of any Stirling engines that can produce usable electric power at these temperatures.

@Ergenics can I put in my car? I heard Bob Lazar did it.

Thanks for confirming my thoughts on your system. A complex enough system should be able to cycle a sealed piston engine or turbine. My guess is that the piston setup would be better for smaller applications.

[cujet]

it seems to me that a piston based system must use multiple cylinders for even power output. If I understand correctly, you must reverse the system each cycle. Do you have any thoughts on the mechanics of how to do so?

[Ergenics]

The cycling of hot and cold water through the hydride heat exchangers can (and will) be done independent of the cycling of the expansion pistons. The expansion pistons will be controlled by reed and limit switches. Eventually, the gas expansion unit will be a turbine specifically designed to run on Hydrogen.

[Voice0fEnergy]

wonderful technology. I hope to see more about it soon.

Thanks
