Solar power is required to extract the hydrogen. Hydrogen is more efficient with current technology than solar (The solar energy that hits the earth
in every square foot is enough to power roughly 30 homes). Our current solar cells are not anywhere near that efficient. With even the top solar
cell technology, we'd only be able to power one average sized (1500 square feet) home with roughly 500 square feet of solar power.
Hydrogen is an energy source that we can harness with much greater efficiency. Between hydrogen burning and the turbine, this device, as laid out,
will operate at roughly 60% efficiency between the hydrogen fuel and the electrical output of the turbine.
Finally, how will it not generate CO2 in the exhaust? It's the simple physics of hydrogen combustion. No fossil fuels are used in this device. The
spark that facilitates combustion (and with enough provided hydrogen, may only need to be used once, in order to sustain combustion) can also be
generated by the solar cells. When hydrogen burns, it combines with oxygen to combust and release its energy. The result is nothing more than water
vapor. This is well documented.
To answer your final statement...
CO2 IS a major greenhouse gas. I have been prepping to go back to school for aerospace engineering, and have started some of the basic math and
science courses. CO2 is a natural greenhouse gas. It's the reason that the Earth remains warm and comfortable, while our other two neighbors - Mars
and Venus (both within the "comfort belt" in the solar system remain either extremely hot or extremely cold). Mars' atmosphere is too thin, and
Venus' atmosphere (which can reach temperatures over 800 degrees F.) is thicker, and loaded with CO2. CO2 has also been listed as the most desirable
greenhouse gas in the Mars Direct project, in order to warm the Martian atmosphere.
CO2 is certainly an issue in global warming.
