i'll start. i'll buy a H-car and bathe only twice a month
- System-Idle0
i'll be in my shed if anyone needs me
*tink tink bang knock

saw a documentary about a guy who drives his truck on chicken-lard... hmmm

"System that's the hydrogen engine, hydrogen (H) burns (combines with Oxygen (O) ) and produces only water (H2O)"
...and: heat!

isn't the problem with a Hydrogen car is you have to use lots of energy for the Hydrogen don't you?
Anyway, the greenhouse gas problem is from power stations, not cars so much. The programme said that as a result of cleaner air, the greenhouse effect is showing its full power

I reckon what ever we do to create energy will have an effect on our environment. WLoads of wind turbines will probably effect the gulf stream or something
Blofeldt
(Jan 14 05, 02:56)essentially energy can neither be created nor destroyed, merely converted. It follows then that even a wind turbine takes energy out of the winds that rotate its sails in order to turn its dynamo and generate current. Wind however is caused by having areas of high and low pressure in the atmosphere which in turn are caused by many different factors. I don't see wind turbines or solar energy detracting from the environment in the same damaging ways that fossil fuels do or the potential ways that nuclear fuels can.

That's to MAKE the hydrogen

Hydrogen is expensive (energywise) to produce, electrolysis can do it if I remember correctly....
The greenhouse gas problem ISN'T just from powerstations but rather from any CO / CO2 source.

Wiki has a simple intro to fuel cells and hydrogen. There is also an article down the bottom about hydrogen from renewable sources. which is preferential.

so you put lard in your fuel tank stewardez.
that will smell as delicious as french fries if you start your engine.
- Blofeldt0
yes, any CO2 source. But the primary man made CO2 release is from burning fossil fuels.
- MX_OnD0
petrol and diesel and indeed kerosene are all fossil fuels....

Wouldn't electrolsis require a lot of electricity?
- winter0
electricity is clean.
houses should have photo-sensitive roofs, then a mini H-station for fuel needs and that would be it.
FREEDOM!

Wouldn't electrolsis require a lot of electricity?
Blofeldt
(Jan 14 05, 03:23)Yes. About 3kg of electrity for every cm of Hydrogen.
- MX_OnD0
electricity IS clean but must be generated.....
- winter0
light, wind
not a wind that is light though :)
it's possible. it's purely a matter of economics, big companies, country policies, etc.

the final bit about if the greenland ice-shelf melts and the methane-hydrates that are frozen beneath begin to melt, it will release 18-billion tonnes of methane into the atmosphere, and methane is worse for global warming than CO²!!!
shit
- MX_OnD0
very light winds are already enough to generate 'leccy with....
This place is near where my girl's from in Denmark and is the world's largest wind farm.... we visited it last summer, pretty impressive!
