I have no idea how much power is required to generate hydrogen, but I do
agree that a hybrid car like the Prius fitted with super efficient solar
panels is probably the best approach in the short term. It could trickle
charge the batteries while parked in the sun.
I do know that unless automotive engineers and Governments do something
soon
there will be civil war if gas prices keep rising as they are. It has
already started at gas stations around Sydney, with U/G tanks being
syphoned over night, drivers filling up and driving off is rampant, and
general anger and outrage in the community. Get ready for the backlash.
Michael, Downunder.
The sun does not shine everywhere all the time. There is not much
automotive
engineers can do, they have not already done, given the draconian
government
rules on crashing and emissions. Perhaps turbo compounding but at great
expense
that would only be 20% less fuel max. IC engine eff. would then go to
around 36%
overall. There is no other way around the laws of thermodynamics. IC
engines have
been around 30% efficient for the last 70 years or more. Same for
photocells at about
5% efficient. It takes way too many square yards of expensive photo cells
to get
enough juice to do anything. If you want cheap juice go nuclear.
The real price of crude is $60 US a barrel. There are forty gallons
in a barrel. That is $1.50 a gallon for crude. Add $0.50 or so to make
gasoline
out of crude. The rest is taxes. In many cases taxes are computed on a
percentage.
Double the basic cost and taxes are doubled as well. The Government loves
money.
They won't cut taxes unless you make them do it. How much is fuel down
under? Nobody is rioting in Europe where gasoline has been well over
$6 a gallon US for years and years. God knows what it is now. They still
drive Sport Utes and MB 600's. If you want to cut your cost... cut the
taxes.
Paul Lamar
Paul,
You hit the nail on the head, government loves taxes, which is why they have
sat on their backsides for 30 years and done nothing, even though this
looming oil crises was well known back then.
I was not suggesting solar panels be the sole power for cars like the
prius, merely a supplementary power source. Sunshine is free, why not use
it.
The CSIRO in Australia proposed a viable alternative using bio-diesel
many years ago, and it would have provided many struggling farmers with a
cash crop, which could have developed into a national industry providing
home grown fuel, but the Government poo pooed the idea. Why?? Guess who puts
mega bucks into their re-election accounts. Need I say more.!!
And it's exactly the same in the USA, there is a viable alternative, but the
people we elect refuse to govern in our best interest, because of fear they
might upset an oil mogul official. Collectively we need to stand up and say,
enough is enough.
Pump prices here where I live is AU$1.40 a litre and rising.
OK stepping off my soap box.
Michael.
