Mayf;
I just got back from being out of town for a few days so maybe someone else
has already answered this better than I can.
The deal on CO2 heat gain is the same as leaving your car windows up in the
sun-- the light from the sun has a large proportion of its energy at short
wavelengths and that passes through the glass easily where it is absorbed by
the car's interior. This heats up the dash, seats, etc to maybe 150F and
these hot surfaces radiate their heat at a much longer wavelength (the peak
wavelength of the radiation is dependent on the temperature of the surface--
very hot = short wavelength and warm = longer wavelength). Long wavelength
radiation is not transmitted easily by glass so there is a net gain in heat.
Ditto for CO2.
The sun's surface is roughly 6000F so it radiates visible light (some IR and
UV, too) but a cool surface such as the human body radiates in the long
infrared (about 5 to 15 microns).
H2 & O2 are liberated by the number of Coulombs of energy you pass through
the electrolyte. Coulombs are amps X seconds.

Subject: [Land-speed] OT: Green House Gases.. and an Electrolysis Questionor
2..
Too hot to work out in the shop much today so I figured I would sit
around and scratch my brain a bit.. Been thinking about green house
gases and how they work. Co2 and methane, I think (dangerous) heat the
earth by reflecting infrared heat back downward. Ie they trap the heat
in the atmosphere. Now here is my question...if they reflect the heat
back inward wouldn't they also reflect the heat from the sun in those
wave lengths back into space? Seems that would be a net zero gain. Any
atmosphericic chemists or other smart people out there that can explain
it to me?
Next, how the heck do I figure out how much hydrogen and oxygen are
produced for given voltage, current and electrode sizes? I know that
electrolysis works at a minimum of 1.2 volts and just milliamps, but
what if the volts was say 12 volts or 24 volts or 40 volts and 20 amps?
If the electrode is too large will it be effective as a gas producer
because the current density is lower?
mayf, way off and far out in a hotter than hell pahrump...
