Gas Prices

[Turtle]

Current price for Regular unleaded gasoline in my area of Vancouver USA, is $4.29 per gallon.

From a post I made in the My belief in Global Warming is getting shaky thread yesterday at 12:43 AM:

 

.....If he really wants to know what's causing the dramatic spikes in gas prices maybe he should look into the Enron Loophole that was built in to the Commodity Futures Modernization Act of 2000, and the rampant increase in hedging and speculation in the market place that has followed. This piece of legislation was sponsered by Republican Phil Gramm of Texas, and signed into law by Bill Clinton.....

Does it take a lot of energy to extract hydrogen from water?

 

 

I guess you have to define "a lot" but yes it does take significant energy to separate hydrogen from water.

 

another thing to think about when using methane is that a methane powered car would be cheaper to build, I know currently that is not true but it's only because you have to convert a regular car to methane. A regular car has lots of things about it that allow it to use gasoline both efficiently and to curb pollution. A car from the 70's burning methane is significantly less polluting than a car from the same era. It stands to reason it would be easier to build methane cars that pollute less than it would to make gasoline cars that do. So lots of expensive things that go on a gasoline car could be left off a methane car. Not taken off a gasoline car then made to use methane.

Turtle's thread (http://hypography.com/forums/science-projects-homework/13409-hydrogen-product-photovoltaic-electolytic-cell.html) covered this quite well. :edepress:

 

I'm still contemplating the ANWR situation and it's effect on oil prices. This is an interesting link:

Does it take a lot of energy to extract hydrogen from water?

 

To calculate the energy needed to separate hydrogen and oxygen from water by electrolysis you can use Faraday's Laws of Electrolysis.

 

[math]Q = N_e \times F[/math]

• where Q is the charge in Coulombs
  
• [imath]N_e[/imath] is the number of electrons
  
• and F is Faraday’s constant = 96,500 C/mol
  

One gram of hydrogen is approximately one mole.

 

[math]Q = N_e \times F = 1 \: mol \times 96,500 \: C/mol = 96,500 \: Coulombs[/math]

 

Converting to energy requires:

[math]E(joules) = Q(Coulombs) \times V(voltage)[/math]

 

I didn’t calculate the voltage but got it here

 

[math]E = 96,500 \: C \times 1.23 \: V = 118,695 \: joules[/math]

 

Or 0.033 kilowatt hours to produce one gram of hydrogen.

 

It is, however, very rare to use hydrogen from water like this. The vast majority of hydrogen is produced from hydrocarbons such as natural gas.

It has to do with supply and demand. The demand in newly industrialized countries has sky rocketed while production has stayed about the same. The oil companies are making huge profits but this only to off set the future and current cost of exploration of new oil reserves.

 

The problem of high fuel cost is not going away. What we need to decide in the US is to elect a president that thinks that drilling new wells and continuing and expanding a war in the middle east is the solution {McCain } or push for alternative sources of energy { Obama } This is going to be the issue that Americans need to decide on in the next election.

 

Your comment on McCain is ridiculous and unfounded!

Current price for Regular unleaded gasoline in my area of Vancouver USA, is $4.29 per gallon.

here it has almost doubled in price in 12 months

Like Canada we have vast areas to connect

It is about $1.70 a litre. Some mathamatican (not the Hubble one!) will need to convert that.

There is 38c tax in that + a 10% GST State Tax.

Despite the inflationary impacts of such taxes the government holds on to them

 

 

We (or at least Exxon Mobile) have more Natural Gas than we know what to do with.

The government is subsiding car conversions now (two year waiting list) Most Taxis run on gas. Gas is also heavily taxed.

 

Re Hydrogen from water

Sorry I don't do sums- but i guess the answer is "yes"

A pity. It would be a great way to de-salinate too.

3.785411 liters per gallon (US) * ($1.70 Ozzonian * 0.949902 conversion to US dollar) = $6.11 US dollars per gallon. Glad the US doesn't have any vast areas to connect.

Systematic review on the efficacy and safety of herbal medicines for Alzheimer's disease.

 

J Alzheimers Dis. 2008 Jun;14(2):209-23

 

Authors: Man SC, Durairajan SS, Kum WF, Lu JH, Huang JD, Cheng CF, Chung V, Xu M, Li M

 

A systematic review was conducted to assess the efficacy and safety of herbal medications (HM), as either monotherapy or adjunct to orthodox medications (cholinesterase inhibitors and nootropic agents, OM) for Alzheimer's disease (AD). Sixteen studies testing different HM were included. Out of the 15 HM monotherapy studies, 13 reported HM to be significantly better than OM or placebo; one reported similar efficacy between HM and OM. Only the HM adjuvant study reported significant efficacy. No major adverse events for HM were reported and HMs were found to reduce the adverse effects arising from OM. Imbalance in ethnicity among participants was observed; gender distribution was unclear. Heterogeneity in diagnostic criteria, interventions and outcome measures hindered comprehensive data analysis. Studies comparing HM with OM suggest that HM can be a safe, effective treatment for AD, either alone or in conjunction with OM. Methodological flaws in the design of the studies, however, limited the extent to which the results could be interpreted. Among various HMs, the safety and tolerability of EGb761 was best established. Further multi-center trials with large sample size, high methodological qualities and standardized HM ingredients are necessary for clinical recommendations on the use of HM in treating AD.

So you're saying that Alzheimer's is contributing to the gas prices?

 

[Moontanman]

There may indeed be plenty of natural gas but I don't see any TV commercials promoting NGV yet, but I see a lot of them promoting hydrogen vehicles and we don't even have hydrogen available on a commercial basis. makes you wonder just where the priorities are, it's not on replacing gasoline anytime soon that's for sure.

[Moontanman]

I'd like to convert my Jeep to propane, natural gas isn't available to my home where I am now. I wonder if they offer kits for that? At the DuPont site I used to work at all the fork lifts and tow motors were powered by propane. It had to be clean burning because we ran them in enclosed spaces.

Hi Turtle,

 

I paid 12.9 cents per liter for fuel in early 1978, just after Australia went to metric weights and measures. The massive increase in the price of fuel in the past couple of years seems to herald the neo age of globalism along with its handmaiden, rampant speculation.

 

Glad the only remaining vast unconnected areas in the US lie between the ears of the politicians who cooked the whole thing up.
