Yes, but the energy density of the energy storage mechanism in the cybertruck is substantially lower than a gas pickup truck
Not a Cybertruck fan myself, but unless you are going to tow or take many long road trips, an EV truck will work great for anyone who can charge at home. And most people don't tow, or take long road trips, with their trucks.
I am not a fan of the truck, but let’s make some sense here
I have a lightning and it averages 0.5kwh/mile and my electricity price is $0.15/kwh, so it costs me $0.075/mile to drive. At current gas prices that's pretty much the same as a very efficient hybrid compact car (55mpg @ ~$4/gallon). If I had solar I could probably offset almost all of the lightning fuel cost based on where I live (sunny) but it's so cheap it's not worth it.
Do you mean "much more efficient" in places where electricity rates are significantly higher than the national average? Or only much more efficient when compared to when you're charging at charging stations?
Of course the Prius Prime on electricity is way more efficient than both, but it still uses a lot more energy than a house.
Yes, driving, compared to living, uses ridiculous amounts of energy.
Actually newtons are just a constant factor (3.6) compared to Wh per km, since there are 3600 seconds in a hour while there are 1000 watts in a kilowatt. For example 144 Wh/km (or 14.4 kWh/100 km) would simply be 518 N. This also means that pushing along a Tesla on the highway at constant speed is roughly as hard as holding a 50 kg weight, giving you an intuitive sense of how "hard" it is to keep things moving.
Of course, in everyday life, since we buy electricity from our utilities in kWh rather than joules, it's more convenient to talk about kWh per km (or per mile).
- the Cybertruck uses almost twice as much energy as your Niro EV
- the 40% efficient Prius uses about 2.5x as much energy as your 95% efficient Niro EV.
what seems off?
Driving in general uses a lot of energy. It’s the physically moving a 1,000 kg or more object that takes a lot of energy. Orders of magnitude more than a few lights or a phone. Same with flying of course; also moving a heavy object.
ICE trucks are equally inefficient for towing. People just don't seem to be able to factor it in.
Imagine a trailer takes 1 unit of energy to move, and ICE truck takes 5 units to move itself, and EV truck takes 1 unit to move itself.
The ICE truck towing it would go from 5 units to 6 units, reducing the range by 16%.
The EV truck would now go from 1 unit to 2 units, reducing the range by 50%.
So the better your efficiency, the worse you are at towing. Ideally EV trucks would have such a huge battery that even when the range is reduced by 50%, it is still as long as a gas truck's range, but modern battery technology is still too sucky to achieve this.
Not so sure about that one, boss. I can fully-load up a Ford Ranger to its 7500lb rated towing capacity and lose ~10% in fuel economy/range while you just dropped something like 30% (from the base power package range of ~240 miles, platinum package at 300 miles you're losing half if you only get 150 miles out.)
All cars just use a ton of power moving a lot of mass. It is actually impressive, it's like 100KW at full tilt. I think i saw someone do the math for how much power transfer you would need to get EV charging as fast as gasoline refuelling: It's in the megawatts.
The only way you could signifigantly reduce power usage of vehicles is to reduce mass dramaticially with a motorcyle or autocycle. The Aptera is an interesting autocycle design based on this line of reasoning, but we are also seeing the emergence of a lot of electric motorcycles.
Also regarding filling up an EV as fast as gasoline, there’s a company in China that has demonstrated charging from 20-80% in 5 minutes. They’re using 3MW charging.
It makes you realize why gasoline has been so popular for so long, you can stop for 5 minutes and dump 500 kWh of energy into your tank. Unfortunately most of that is wasted as heat during the combustion process.
Yeah that's the exact post I saw. I didn't believe the video at the time but I suppose it's possible with enough battery paralellism and cooling.

I think in general, a country trying to become industrious and eco-friendly by saving energy is like a person trying to become a millionaire by pinching pennies. Once you have optimized an economic system to eliminate the major cost centers, you're going to have extremely hard time improving it through further cost savings.
For example, If my expenditure roughly matches my income, I would need to eliminate 100% of my expenses just to make enough surplus to match doubling my income. Once I have managed the major cost centers (rent, insurance, etc.) it's not going to be worth my time to further optimize my expendature, the time would be better spent improving my income
For EVs, the fuel cost is already low. The next cost centers are like maintainance, tires, battery life. It would be better to attack these other cost centers or somehow pursue functionality that increases utility of the car.
That said if you have a Mall Crawler who's heaviest loads are your monthly Costco run, an electric truck would probably be great for you. I still wouldn't recommend a Cybertruck though.
