Oil Down Again
« on: August 08, 2008, 10:46:56 AM »

Man nearest gas station near me is still in the $4.30s.

In Henrietta it's $3.88 a gallon. I may have to stop at Gander Mountain then fill up.... :D

Topped off yesterday at $3.63 at a 7-11 in Chesapeake. Noticed the BP near my apartment in Virginia Beach was $3.61 this morning.

In wonderful Plant City Florida, it was $3.71 and in Lakeland (a ten minute drive) is is $3.77.  Guess the Saudi shiek might have to pull that 24k gold toilet out of his 747.  Blue water must be getting expensive when us evil westerners don't buy much gas.   :D

all i can say is bring on hydrogen.  Kudos to Honda for bringing out an oem car that runs on H. If we pick a fuel we couldn't pick a better element.   It is the most abundant element in the universe and its only byproducts are pure oxygen and pure water.

Hydrogen is just a battery. And an inefficient one, escpecially when used in an internal combustion engine.

It may be abundant, but it's locked in compounds such as water. It takes energy to separate it...

they invented something called photovoltaic cells, they use sun light to turn water into hydrogen, look up a company called honda.

ok  I got in trouble for bring math into another discussion, but here is a back of the envelope estimate...

say you use 40 hp to drive for an hour a day.

40 hp = about 30 kw  30 kw hrs...

solar 12 hr of production,

appx 1 kw per M^2 of sun energy hits the ground.

a good tracking solar panel is 25% efficient.  Fixed Panel... lets say 50% of that.

12.5% efficient.  A good hydroysis is 50% efficient...  maybe 80% in a few years.  call it 80%.

.8 x 12.5% = call it 10 %

30KW hrs / 12 hrs = 2.5 kw.  25 kw solar needed to make up for efficiencies.

current US price $8 per Watt.... $6 after tax incentives. 

6 x 25,000 = $150,000 for the solar collector... how much for the car?

Nuke plants?  Electrical grid?  No one is saying you have to do it exclusively at home although it would be an added bonus.

Don't you get very efficient energy out of a nuke plant?  If you are not transmitting the power and directly generating Hydrogen, what does it then cost?  Could you not distribute that out like gas is now?

You are looking at one option and dismissing out of hand.

1 kg of hydrogen has about the same energy as 1 gallon of gasoline.

At 10c per kw/h, it costs about $6 just for the electricity to produce 1 kg of hydrogen. That's without counting capital costs or profit.

And that kg of hydrogen is a gas. It needs to be heavily compressed or liquefied to make it useable in a car. About $1.20 - $2 to compress or liquefy the hydrogen.

Even with economy of scale, about $10 for the same energy as a gallon of gasoline.

That's why they are looking at fuel cells for cars. They have the potential to be 2.5 times as efficient as a petrol engine, so it could be as little as $4 for enough hydrogen to drive a car as far as a gallon of gasoline. Fuel cells are currently very expensive and nowhere near efficient enough, though.
