Interesting concept here. I can see using Joules to measure energy use of something like a clothes dryer where current and resistance heating are involved and price is by kWatt-hour. I suppose one could use the "newton-meters" aspect like foot-pounds of torque, and apply time to get a "horsepower" like equivalent. More interesting than the dreary old concept of "Watts" in an ICE. Maybe even cooler to measure gasoline potential energy in "calories."
I hear it takes about 15 horsepower (11 kWatts) to keep a car cruising at 60mph.
So to drive 60 miles, that would be 1 hour so about 11,000 watts times 3600 seconds or 39.6 of your MegaJoules. So at 3 cents per, about $1.19, your Bargain of the Millenia.
This was fun but of course meaningless, since ICE cars use miles/gallon and energy potential does not translate directly to work.
3 cents per MegaJoule for gasoline energy

Yes, I know. My point is that nothing beats the energy density of gasoline and the other petroleum distillate fuels.

Isn't there enough desert to make a huge solar desalinization plant there?
Patrick saysWhat is the energy source used for desalinization?
Electricity.

It would be silly to build a desal plant in the desert. They belong on the coast.The panels are in the desert already.
BTW, desalinization plants could be a perfect dump of all that excess solar energy generated during the day. It would depend, of course, if they can be safely stopped for the night.

I read a book about this once. A physicist said that nothing will ever beat fossil fuels not only because of the energy density, but also because the other reactant (oxygen) does not need to be carried, and the waste products are immediately expelled, making the vehicle lighter as it runs. Neither of those is true with batteries.
But who really knows? It was assumed that it was impossible to make little battery powered drones until people discovered neodymium magnets and lithium batteries.

Exzactly. I've always wanted to see one with one of those windmills w/ buckets attached in order to lift the desal water high into the sky. Where it's dumped on top of a giant water slide that goes from Carlsbad to Arizona.
That would be cool.

Apparently gas prices are not yet high enough for Biden's taste:

Putin needs these oil prices above $80.
