Dharry I'm curious about this Chinese project to turn CO2 into CO.Is it to be used as fuel, then turning back to CO2? If it were to be just released into the atmosphere it would turn into CO2 under sunlight.
As for natural gas I haven't heard the term "Peak Gas" yet. There is a massive amount of methane hydride on the sea floor for the taking. Natural gas may not even be a fossil fuel, as several other planets have it in their atmospheres and presumably had no life in order to give rise to fossil fuels. Therefore there may be a massive amount in the Earth if methane distribution isn't restricted by previous assumptions.
