And the only bi-product is water
This was on Top Gear in case you missed it.: Hondas new answer to Oil running out
I know this has nothing to do with houses, but thought a few of you would be interested in this.
If you don't like it 'Move On' as Clarkson would say.
This car was featured on Top Gear last night. I don't know why they make them look so daft. But make this look like a normal car and it will become very popular.
And Oil this may well make hit $10 a barrel quite soon. Only available in Califoria at present but I believe Honda are OK at mass production.

This car runs on molecular Hydrogen, which does not tend to exist on earth (because it likes to explode when it meets oxygen and a little heat).
So, the molecular Hydrogen needs to be made, which takes energy, which comes from......that's right, oil or nuclear fuel (or renewables, but at the moment they are insignificant).
So in order for this car to be part of the answer to oil running out all of the Hydrogen needs be made using either nuclear energy or renewable energy, which is almost certainly not the case presently.

Thanks Baroo
Trust Top Gear to only give us half the story.
I had wondered how we got the hydrogen and how much energy was involved in that.
Does seem a significant step forward though.

I think working hydrogen-fuelled cars have been around a little while now - a couple of years anyway. But, yes, the fuel costs a fortune. Back to pedal power. Clarkson has plenty of stored fuel in his gut for that.

@baroo: the problem is not that it burns, it's simply that it's very light and the earth doesn't have enough mass for gravity to retain it. It simply boils off into space. The planet has to be of the mass of Jupiter, Saturn, Neptune or Uranus to retain hydrogen, which is why they're termed 'gas giants', being largely made of hydrogen gas (Jupiter estimated to be nearly 90%).
This is the fundamental problem with hydrogen - it just doesn't exist as a primary fuel and keeping it around as a secondary one requires high pressures and/or low temperatures, both of which require energy and pretty heavy containers. Hydrogen fuel is just a silly idea, but one that has political support because the naive chemist sees that the resultant product is water.
