There are some interesting murmerings going on over in nelson about a hydrogen powered loco...

Andy Bell on the yahoo groups saw James May thing with such a loco....though quick check on You Tube shows several versions...oh well thats my secret idea for the 16mm NGM Moty Diplock Throphy gone for a burton.......

ah yes I can hear it now, the sound of loco's exploding in back gardens all over the country........

Here is a link to the video of the prototype locomotive.

The one that went "bang" on James Mays episode was the alcohol powered one and not the hydrogen powered one.

How does hydrogen power work?

I saw it working on Saturday on Andy's stand at an exhibition in Porthmadog - very impressive!

Hydrogen power and how it works.

Water is H20 two hydrogen atoms to one oxygen.

To get the Hydrogen out of water we put a current through two electrodes.

one electrode gives Hydrogen and the other gives Oxygen.

A fuel cell uses this process in reverse, using something called a Proton Exchange Membrane. In this one side of the membrane has Oxygen and the other side has Hydrogen, A chemical reaction takes place and Heat, Water and Electricity are produced.

The Fuel Cells that are being used for development in the loco are passive cells, that is that the Oxygen is obtained from atmosphere, and the Hydrogen comes from metal hydride storage under low pressure.

More details on how a P.E.M. Fuel Cell can be found here: http://en.wikipedia.org/wiki/Proton_exc ... _fuel_cell

Hope that this helps,,
Regards, Andy

Thanks Andy this is interesting, I notice a by product is heat. I wonder if you used one for radio control of a steamer if you could use the heat to assist as well.

New boy sticking his nose in, but this is a pet subject of mine.

Whenever the topic of future 'green' carbon free energy crops up I suggest that there is only one answer. That is a nuclear hydrogen future. Nuclear energy produces bulk electricity which can then produce the portable hydrogen.

I appreciate there are a number of problems to be solved, but as the Victorians solved the street horse s--t problem by inventing the IC engine I reckon the solutions will come.

For nuclear it is the need for smaller units and commercialising fusion reactors. For hydrogen it is storage. Smaller 'fuel cells' will appear and IC engines are relatively straight forward to convert.

So look out for the hydrogen powered Mamod.

Christ, they're fast enough as it is, if they're hydrogen powered they'll be breaking the speed of light!
