It would be cheaper than gas, but not by much. Plus I think its like 3 gallons of water needed for 1 gallon of hydrogen equivlient. I think power wise it would be around 2 dollars and change for the gallon eq of hydrogen gas.
Anyone notice the price of diesel has dropped???

The bad news is that most of that electricity came from heat engines, so it _is_ subject to that hit. They're being downright dishonest to ignore it.
The real number, of course, is Dollars Per Mile.
Here in SoCal, energy costs about 15 cents per kWh.
It takes the same amount of energy to push a car through the air regardless of where it came from. A typical car uses about 40HP at 60MPH cruise. This is about 30,000W. Do this for an hour and you consume 30kwh. or about $4.50, assuming perfect efficiency.
If I take that same $4.50 and buy gasoline I will get about 1.21 gallons at current high prices. Dividing that 60 miles by 1.21 means that the electric car is getting the money equivalent of 50 MPG. Not bad, but not exactly 140MPG either.

Opps...
Neat idea anyway with Honda, but hydrogen will never come to full use. We may use cng powered cars with reformers that convert the cng to hydrogen in a fuel cell, but no one will want a mini hydrogen applicance in the garage. Maybe a mini ethanol plant, but those are ten grand and many insurance clauses have something against keeping fuel inside your house.
Really its going to be more of the same with the hybrid cars and trucks being geared more for performance than economy and priced high. Still the economy cars will also be the most affordable cars. Ultimately all cars and trucks will slowly go up in fuel economy.
I seriously think the air powered cars will be the new ecnoboxes. Just think, you can pull up to a gas station or your garage and fill your tank with air and go.

I suppose that the table _might_ be valid if you live right next to the Columbia river, but for folks in urban areas is it decades out of date.

I use va dominion power in VA and it has steadly gone up the past few years. It use to be like 3-4 cents, now its like 8. So far we have the older style meters, but they are talking about upgrading them all.

But yes, electricity averages $0.09/kWh for me, although you can choose your pricing methodology (peak/off-peak pricing, green power, standard). What can I say? Dams provide cheap energy.

The rav4 was listed at over 100mpg if you look it up in the epa hand book. The epa did an estimate at that time if it were to use the equiviliant.
I was trying to say the price of gas makes it affordable to use hydrogen made from the outlet.

However, in real life, it's more like 40-45 MPG for a normally-driven Prius. More than that requires careful effort (along with considerable disregard for other drivers) on the part of the Prius driver.

Not bad for a mid size sedan. One of my co workers who does mainly highway driving gets between 51-57mpg.
My 240d benz was roomie and got 32 mpg.
