People! fossil fuels are running out, we need to do something about it. This is the start of a new beginning.

The question no one seems to ask is what all this extra water vapor will do to our environment. Let’s take greater LA for an example. There are about 17,000,000 people and at least 5,000,000 cars. What happens when a large number of them are pumping water vapor into the air? Would that change sunny LA to muggy LA? rainy LA? What happens when this water vapor filled air has to go over the mountains to the north, east or south? Floods, anyone?

If I’ve made an error in my deductions please tell me where because if I’m right this could be a ecological disaster of its own.

Hydrogens a dead end. Look, we already have two perfectly good generation and distribution systems for energy, the electric grid, and the existing petrol distribution systems.

If the electric grid becomes the primary distributions system and the existing petrol system becomes a distant secondary system then things will be better.

Charge your car during off peak hours and have an on board generator for the three or four times a year you want to travel. For those with a house that has some space, make your own electricity during the day and sell it back to the grid.

Building hydrogen generating plants, designing hydrogen distribution and dispensing systems is all just stupid and should hit the ash can of bad ideas along with bio diesel, ethanol made food that we could be feeding people with, and other lame brained lobbiest driven ideas.

But I could be wrong.

My father in law is an engineer who did some work for Honda on their planned hydrogen feul cell vehicles. Seems the tricky part no one can get right is refilling the hydrogen tank. Something about hydrogen being extrmemely combustable and having to maintinain high levels of pressure….

That said, I’m willing to take my life in my hands everytime I stop at the pump, after all if someone pulls up to the station now and decides to answer their cell phoen, I could be lookign into the abyss

Gee, just because oil is sitting underground for millions of years makes it a fuel while hydrogen bound to oxygen isn’t! Well where did the oil come from, eh? Ultimately from the sun and gravity of compression. Where does the hydrogen come from, eh? Ultimately from the sun via direct photovoltics or wind. If you use oil to produce hydrogen you are doing a double down efficiency loss.

Its time to get off the bandwagon of ‘carrier’ vs ‘fuel’. All chemicals that react are carriers. They store the energy in there bonds and release it during reactions. The best candidates for ‘carriers’ are those that are very difficult to separate out of their stable state. Why? Because they hold more energy than those that are easier to separate.

Its also time to get off the, gee, its not here now so it never will be, bandstand. Centralized oil by big business has had its day. Now the little guys with multiple distributed energy capture devices will lead the way. Have you bought a wind generator yet? Have you installed solar panels? You need to ‘get off the grid’ and start producing energy for your home AND your car.
Stop griping, get moving.
