Up and Down daily in no particular order..
If this didn't happen gasoline would be $10.00 a gallon by now...

It will be at some point ,got close this time around.

Depends on Russia, oil could be $250 but also the power could go out at any time. Buy a horse

Not so cheap now Barney.

Here are some rough calculations that surprised me. 22 cents per kwh is the price I pay, which is probably higher than in some parts of the country. The bottom line is, fuel costs for an EV are close to those for a gasoline-engine car. So an EV may not save any money. The only advantage of the EV is, potentially, not heating the earth to the point it is uninhabitable. That's probably worthwhile.

gasoline = 120,000 btu/gal
33% efficient IC engine = 40,000 btu/gal usable
1 million btu = 25 gallons
25 gal X $3.50/gal for gas = $88/mbtu

electricity = 3412 btu/kwh
75% efficient EV = 2600 btu/kwh usable
1 million btu = 385 kwh
385 kwh X $0.22/kwh = $85/mbtu

You can't just calculate the efficiency of the EV. You need to add electric generation efficiency to the mix to get a real number.

Lots of talk of electric rate per mile verses gas per mile. But, what is often left out of the EV cost equations is the much higher price to buy one verses a similar ICE vehical.

Then, being so much heavier than a comparable ICE vehicle, how long dose a set of tires last ? The price of a new set of tires have become a huge expense.

True. But I was looking at "efficiency" purely from the car owner's point of view -- the cost per mile of gassing up or charging. Generation (and transmission) efficiency help determine the final cost of the electricity delivered to my garage, and the efficiency of locating/drilling/pumping/refining/transporting gasoline help determine its cost. It surprised me that the costs, right now, are comparable. In the long run, solar and wind generation may reduce the cost of electricity relative to gasoline, or it may not. But again, the benefits of not cooking the planet count for a lot.

Incidentally, the state of Maine cut down lots of brush and trees around a couple of highway interchanges near me. Now they are installing solar panels in the cleared area. There are hundreds of miles of wide cleared/mowed strips alongside these highways. I wonder if it is economical to spread solar panels three or four abreast over a hundred-mile strip?

With subsides they will probably do it. Otherwise it wouldnt make the builders money. But using wasted space is where they belong if they are going to install them so that sounds ok to me along a hiway.

Im sure all the fires and bombs going off in Ukraine made the planetary good (if any) of solar panels mute. They worry about me burning a plastic milk carton while asphalt is burning by the acre over there.

Miles for the day: 700
Average Speed: 78.5 (thank you American heartland)
That's starting with a full tank, fill-up when I hit 1/4 tank midday and I had a quarter tank left at the end of the day. If you are slow poke driver and set the cruise at about 55 you could probably go for 8 or 9 hours on one tank on any interstate. Not me, there was points the grades were pretty steep and it was hitting 3500 RPM in third to maintain 90, keep in mind the speed limit was 80. I passed a cop on the side of the road going about 93ish and kept on going.

There has only been one time during this trip I had concerns about getting fuel. I entered Sequoia National park from the northern entrance with a full tank, passed a regular gas station inside the park because I had 3/4 tank. Exited the southern entrance and grabbed a room but there was no gas stations before the motel. Entered King's Canyon the next day with about 5/8 tank. This is dead end road and I had some minor concerns about finding gas station once I turned around and exited the park.

I didn't need it but I filled up here inside the park for $8 a gallon, 4 gallon minimum. I couldn't resist despite the price. This did allow me to take more interesting route to next destination.

We should have definitive proof of the 100 year longevity claim by 2122.

The real future of transportation is not EVs, it's hydrogen. One of the most common elements in the universe. It powers the Sun and covers most of our planet in the form of water.

All these cars that are connected to the web can be shut down whenever anyone wants to. Forgot to pay registration, oops car don't work. Didn't get it inspected, too bad, no go. Teslas are the worst for this and even though Elon is an interesting and bright guy I will never buy his product because when I buy something I intend on owning it.

I imagine some have already figured out how to block signals to/from that feature. Like the shielded bags for cell phones to block signals from remote control.

You will never own the operating system of most computers, unless

developed with open source software, even then many people hold

rights to certain necessary routines.

You can only buy a license for use.

Hydrogen on earth is plentiful ,but only in water bonded with oxygen

in one of the strongest bonds and is not easily separated but by using

large amounts of energy.Using "free" energy from the sun is one way to

do it,but why not use the energy directly and avoid the energy loss in the

transition?

But if I buy a computer I can resell it to someone and they dont have to purchase the rights again after I already paid for the rights.
