The 212-foot-tall core stage, SLS (Block-1B) part of the rocket on launch day will be packed with 537,000 gallons of liquid hydrogen and 196,000 of liquid oxygen, which will fuel the four engines at the bottom. All of that fuel and engineering translates to a boatload of power--8.8 million pounds of thrust:
Didn’t say it was impossible I said it was difficult. ... And expensive !
#1 Power generation constraints limit how many EV’s can be charged
#2 The batteries catch on fire and can burn down your house
#3 Limited range

I think you forgot the SARC tag.
Someone might think you were serious.
Toyota and subsidiary, Woven Planet, have created a working prototype of a portable hydrogen cartridge, much as the same principle that portable propane bottles are used. You'll swap them out as needed and they'll be refilled at service stations. But the two companies seem to expect they'll be running a delivery service as well, getting hydrogen canisters out to wherever they're needed.
The cartridges are cylinders, 400 mm (16 in) long and 180 mm (7 in) in diameter, with a target weight of 5 kg (11 lb) when full. They'll carry around 3.3 kWh of useful energy, depending on the efficiency of the external fuel cell used to convert the hydrogen back into electricity. They've got little grab handles on the top, and they're designed to be slotted and twist-locked into place wherever they're used.
They could be used as swappable hydrogen "batteries" for electric cars, motorcycles and drones. They could be slotted into the walls of homes that aren't connected to a power grid, to provide electricity for the whole house through a fuel cell. They could be used to power heaters, or provide electricity in remote places. With a small fuel cell on top, they could be treated as large backup power banks for device charging.
The author’s arguments are threefold:
1. Current demand for EVs is government-driven through subsidies, media, propaganda, etc., so it is unlikely that Americans will every fully accept EVs.
2. Even if all new cars sold by 2035 are EVs, 83.5% of vehicles in operation will still powered by fossil fuels (which reinforces argument no. 1 — liquid fuel infrastructure is not doing away).
3. If today’s demand growth for EVs maintains through 2050, the U.S. alone will require three times the current production of lithium. (And that’s without banning ICE vehicle sales.)
Moral of the story: the state will have to force us out of personal cars before we go entirely EV. And given current urban traffic planning, what with bike and bus lanes, traffic jams by design, etc., that’s exactly what they’re trying to do.
We’ll see!
I can fill up my Ram 1500 in Fort Stockton, Texas and drive to El Paso and back and then fill it up again in Fort Stockton with about 50 miles of range left in the tank. It takes me about 5 minutes to fill it up. No electric vehicle will do this. It is all about energy density of batteries and weight. That is why Air Force One does not have batteries, there are no Tesla charging stations over the oceans at 37,000 feet.
ps
I have zero problems with electric vehicle so long as they are economically viable and not built with one damn cent of government subsidy. The free market always decides what is best.
