"Engineers have built a contraption of water heater size that strips hydrogen out of natural gas while burning the carbon to provide heat for the home."

Ok, now that's just silly. Why not just burn the methane directly in the car and skip the multiple steps?

Hydrogen is a terrible choice as a fuel, it's very hard to store, and has a poor energy to volume ratio.

I should point out they did also create a methane car, and solar electrolysis, so I'm not really complaining about them.
