Most auto makers agree that fuel - cell cars powered by hydrogen produced with renewable energy sources are the end game since they would rely on no fossil fuels and emit only pure water.

When they're burning fuels, no matter how we «Green Wash» them, they're emitting carbon Once you have a «carbon free» electricity supply then using proven technology with either air source or ground source heat pumps is the only way to have «carbon free» space heating and domestic hot water.

July 17, 2013 at 1:39 pm The lapse rate feedback is only a negative feedback (in the general circulation model) if the long wave radiation that is released when the water vapour condenses is emitted to space rather than trapped by increased water vapour.

Water of a temperature emits only certain kinds of wavelengths, these also the same wavelength that water absWater of a temperature emits only certain kinds of wavelengths, these also the same wavelength that water abswater absorbs.

There are no waste products, only water is consumed, producing hydrogen without emitting any greenhouse gases.

The theory is that the CO2 emitted by burning fossil fuel is the «greenhouse gas» [that] causes «global warming» — in fact, water is a much more powerful greenhouse gas and there is 20 time more of it in our atmosphere (around one per cent of the atmosphere) whereas CO2 is only 0.04 per cent....

The shape of the CO2 band is such that, once saturated near the center over sufficiently small distances, increases in CO2 don't have much affect on the net radiative energy transfer from one layer of air to the other so long as CO2 is the only absorbing and emitting agent — but increases in CO2 will reduce the LW cooling of the surface to space, the net LW cooling from the surface to the air, the net LW cooling of the atmosphere to space (except in the stratosphere), and in general, it will tend to reduce the net LW cooling from a warmer to cooler layer when at least one of those layers contains some other absorbing / emitting substance (surface, water vapor, clouds) or is space)

And hydrogen fuel - cells only emit relatively harmless water vapor - no greenhouse gases here.

And using the argument further, the atmosphere can only loose heat by CO2 and water vapour emitting radiation in their respective bands.
