Default . As dirty as hell .

Hi The Road To Utopia , You ask ,
" How does switching from coal to hydrogen
who's by-product is H20 More polluting ? "

Because the hydrogen ,
which is extremely bulky and dangerous ,
will probably be produced in China ... Using coal .

You get the clean because you exported your pollution .

I don't know how fuel cells might come about ,
but I'd bet my last dime it would be as dirty as hell .

Sun Oil is testing hydrogen refueling stations that create hydrogen
/from water/ -- yes, exactly. Do we import water from china?


So you're saying that gasoline, the fuel of the 20th century, is more
/dirty/ than coal, the fuel of the 19th century? So, you'd rather
breathe the air of 19th century London, encased in a shroud of
sulphurous coal fog, than 20th century Seattle?

I still think people should look more at methane. It has some serious
storage advantages of hydrogen, and it is as renewable as well.


Matter-antimatter annihilation. Only it won't take that long.

Maybe. But 20 years on they do not seem to have got very far, in spite
of billions being spent. Also, they tend to explode, and I don't think
anyone got round that yet.

No, oil was once a very common material!


So where's all the Hydrogen coming from? Ooh, I know, lets build
lots and lots of coal fired power stations to produce the power
to get the Hydrogen!



At this rate we will not be around in the 22nd century, we will be either
fried or frozen.

Well best of luck to them! I hope it works, though I don't think
this is going to become a world-wide phenomena in time.

A rather better solution - *any* excess heat can be converted to electrical
power at

high efficiency. First generation devices (good for > 200 C) expected this
year.

Power Chips plc (PWCHF), a majority-owned subsidiary of Borealis Exploration
Limited (BOREF), announces that a patent, titled "Thermionic Automobile",
No. 6,651,760, was issued by the US Patent Office on November 25th 2003.

Power Chips are small wafer-like devices that use quantum mechanical
tunnelling to convert heat to electrical current. In a thermionic
automobile, fuel is burned in a combustion chamber and the energy converters
are placed against the walls of the chamber where they generate electricity
from the heat. That electricity is then fed to electric motors which drive
the wheels of the car. Power Chips are projected to achieve 80% of Carnot
efficiency, whereas a conventional internal combustion engine typically
wastes more than two-thirds of the available energy from burning gasoline.

Almost any form of fuel could be used to generate the heat, from gasoline to
vegetable oils, and even solar energy can be brought into play to add to the
available power or increase the efficiency of the heat conversion. While
Power Chips plc has its own proprietary technology for converting heat to
electricity, the patent itself covers all technologies in which electricity
is generated from heat, such as conventional thermionic and thermoelectric
generators.

really? you don't think that the state of CAHL-LEAF-FORN-YA, the center
