You Can’t Fool Mother Nature
“75 miles every five minutes”
Still way too slow.
That’s 25 minutes for a reasonable 375 mile range.
And Teslas don’t have that much range.
75 miles in 5 minutes. What does this do to the battery’s longevity?
I still prefer my ICE. 350-400 miles worth in UNDER 5 minutes. No effect whatever on the vehicle’s systems.
I “charge” my 2013 Sequoia with liquid go juice in about 3 mins.
Note to the author it is 256KW not 250KW.
Waiting 18 minutes to get a 27 mile charge is nuts.
Sure, that’ll be easy.
Just means that every gas station will have to have its own utility substation next to it.
In the US, gas pumps for consumer use are limited to a flow rate of 10 gallons per minute.
Each gallon of gasoline contains about 130 megajoules of thermal (heat) energy.
If we assume 25% thermal efficiency for the typical car engine (probably too generous), that’s about 33 megajoules of mechanical energy per gallon; at ten gallons per minute, a gas pump is putting 330 megajoules per minute into your gas tank, which is 5.5 megajoules per second, or 5.5 megawatts.
Assuming you could charge your car from a 240 volt hookup, that would be 22,916 amps.
This would require cables with a cross-sectional area of about 23 square inches to carry safely; circular cables of that diameter would be at least 5.4 inches in diameter, not counting insulation and strand packing volume penalties. Call them six inches in diameter. Don’t forget you need two to complete an electrical circuit.
That means that when you’re filling your car from an ordinary gas pump in the United States, the rate at which energy is flowing into your gas tank is equivalent to a rate of electrical energy flow that would require two copper cables, each six inches in diameter, to conduct safely.
Because 250,000 watts of electricity plus liquid is a great thing to be handling every day.
That's well over the equivalent of 4000 old fashioned incandescent 60 watt light bulbs burning at once. Imagine the heat waste (plus the energy needed to just cool the cables and transformers). Then imagine the power needed to charge dozens of cars at once. If one believes that Tesla is the future, one should invest in coal and natural gas.
The last 100 miles are on the back of a flat bed truck, so the math works out.
Betcha I could charge that SOB in less than five minute.
Wouldnt go anywhere after, but I will tell ya that car would glow like hell.
I drive a diesel but while attending the NY Auto Show next month I'll be checking out what major companies are showing. I'll never own one but I am curious.
Tesla 3 is steel bodied, so they are going to have some major rust problems, given how they trap dirt, sand, salt, de-icer etc.

When Tesla fails and is bailed out by the State of CA, they really will be California Leland - rust and all !
I just got back from a short visit. A friend of mine requested my presence for some business we are dealing with, so I jumped in the car and ran up to her place, 2 hours (110 miles) away. The temperature when I left was 44*F, so I had the heat on, the wipers going occasionally, with the lights on and radio playing.
We dealt with her issues, and then went for a short drive (35-ish miles) to discuss and arrange for other matters.
I then dropped her back off at her place, and then came back home. The entire drive home (that same 110 miles, plus a pit stop for a burger) was in the dark, with temperatures just above freezing, at 60+ mph.
In a Tesla, I would need to charge my car for the next 16 hours to get the same amount of distance/energy as I put into the car in 2 1/2 minutes.
That is, *IF* I had fully charged it before leaving my house. I had less than 1/4 tank in the car (I normally keep it full, but oopsed), and still made it to her town, where I bought fuel.
So, were it electric other than a hybrid, I’d have been stuck.
Commuting around town, sure, nice ride. Anything else, gimme my gasoline/diesel powered beastie.
