Robin Hood,

My view is that hydrogen cell powered cars are the real future, but there isn't as much money in that.

Where does the Hydrogen come from?

Water.

I don't know if you are trying be obtuse to be funny or you don't get it. You do sometimes say rediculous things to be funny.

OK, yea, it may come from water, but water can't be used. the water molecules have to be broken down into Hydrogen and Oxygen. It takes energy to do this. In fact more energy than is released in burning the Hydrogen.

The problem with hydrogen cars is the same problem with Electric cars. Neither Hydrogen nor Electricity is a source of energy for cars. They are merely means of Storing energy generated somewhere else.

Certainly not trying to be obtuse.
I'm not an expert in this field (or any other if I'm honest) but I have watched a number of documentary's on this subject ie. electric battery powered vehicles verses hydrogen cell powered vehicles; and the respective technologies and energy needs.
Hydrogen won hands down in every category. Obviously there are some technical issues still requiring resolution (not least the danger of rupture and the potentially explosive consequences) but the conclusion was that the raw material, water, is too cheap and plentiful. No one will make any money.

In my view, electric cars are a significant way off here in the UK. Tesla may announce it's latest improvements to battery storage and charger times to great fanfare, but that only works in California.
The same technology here in the UK would give drastically different performance.
In the dead of winter we need our headlights on (even in the daytime - which is only 6 or 7 hours), the heater on, the windscreen wipers (it's been known to rain here!) etc, and that's before we take into account the Sat Nav, the kids watching their DVD's, phone charging etc.
I might get to the supermarket and back.

I think you guys going with 220 volts was a much better choice over our 110. The metric system on the other hand, should of adopted the inch as the standard length, rather come up with convoluted meter.

Machine tools were already setup to use 1000ths of inches and 10,000ths for some things. Now you have to have two of every thing, just to work on a car. Funny though 1 Kilometer is the nominal depth needed for OTEC to tap water at optimal temperature. The meter was supposed to be 1/1000th the average diameter of the Earth or some silly, useless thing like that.

Again Nautical Miles are 1/60 of a degree, and metric measurement have no use for navigation i.e. we travel on the Earths surface, not along its diameter. On a good note, English is retaining its place as the universal language. It's the only language used by seasteaders, which is ironic considering French Polynesia looks to be their first focus. Next up may be the Marshall Islands where there are no tropical storms at 0 degrees lattitude aka the equator.

For a long time nuclear fusion seemed to hold the most promise, but alas it proves beyond our mortal abilities. Hydrogen does look to be our best method of conveyance, or bio fuel from the ocean, which again OTEC can revive much of the sterile ocean, by bringing up nutrients from the deep. Pumping cold sea water through pipes would make for a great household utility in some locations. Pump it underground and the cold pipes sweat fresh water, with no fear of drought, and Dr. Craven showed it can increase production fourfold, and produce any crop in a tropical climate.

The problem with hydrogen is threefold.
1. It is dangerously explosive. Car accidents would have a danger of literally setting off a bomb.
2. Creating hydrogen is inefficient. The process of separating Hydrogen from Oxygen is called Electrolysis. You can test it yourself. Take a peice of gold and connect it to a 9v battery. Little bubbles will form. The efficiency of any kind of power conversion always results in some loss, I'm not sure how efficient Electrolysis is, but it's still another unnecessary step. You have to create electricity for this step, then covert that electricity into another fuel.
3. You are again using an ICE. They lose 70%of their energy due to thermal heat loss. Another waste of energy.

I've personally owned an EV for almost 5 years and have zero battery degeneration yet. Fueling it with a clean source of energy is the most effective way to reduce polluting that I can think of.
