That’s great. First we use food for fuel, now we’ll use water. Do people think we have an unlimited water supply?
Good point. We can only convert to low-flush toilets once.
It takes more energy to split H2O than it yields.
Actually, we do have a virtually unlimited water supply. Most of the earth is covered with the stuff, and it is part of a constantly-renewed hydrological cycle.
Yeah pretty much.
How many gallons of water are there in the world, anyway?
If it can use salt water the supply is essentially limitless. Fresh water is the type we have a severe limitation on. How much of that do we use for fracturing gas and oil wells?
If it is truly 70% efficient then this is huge news. Converting energy, water and carbon dioxide isn't new technology. Just being able to do it efficiently has been the problem.
Wouldn’t one of the byproducts of combustion be water?
Used in this procress, yeah, we pretty much do have unlimited.
The amount of H2O converted to fuel, is reproduced when the fuel is burned. The water vapor is part of the exhaust. Eventually the water condenses in the atmosphere and falls as rain.
The Hydrogen isn't destroyed from the water, and it return to water as the process is completed.
