What is it like being so terrified and threatened about your manhood all the time? I can fix things, but I don't need to invest in a truck for god's sake.
Well, battery technology is still evolving and there is a way to go yet before both weight and range are considered acceptable for the majority of users. Let's not forget how the IC motor itself evolved from Gottlieb Daimler's first attempts over a century ago, patented 1885, to today's examples capable of propelling vehicles at high speed and over long distances.
Then there is this - efficiency:
So 20% of 12,888.9 W-h/kg is 2,557.8 W-h/kg
You are in denial. We will improve our quality of life by adopting alternate energy sources. Change is good and inevitable. Embrace it or fall behind.. The internal combustion engine is a dinosaur that wastes most of its energy as heat. We can no longer be so wasteful now that we need to make our own energy and stop digging it out of the ground.
Good argument for solar, wind, and hydro. Enough solar energy alone hits the planet every day to power everything on earth for years; technology is working on it, and will succeed. Eventually vehicles will be self sustaining with self-charging solar panels/finishes mounted on-board.
That 1200 lbs. is there for the life of the car, then it is recycled into a new car. The 73 lbs. goes some where else every week.
To get from here to there, we need massive energy storage, to cover the times when the sun is not shining and the wind is not blowing.
Throwing away 80% of the energy when we need to make it ourselves will never fly. Without the free energy stored in the earth the IC engine is history. Using hydrogen fuel cells to power electric motors is 10 times more efficient when longer ranges than batteries are needed.
You should look up the word "Projection" in a mental health journal.
But you have to tote around the battery even if it has a minimal charge, the weight of the fuel decreases as it is used up.
It still comes down to energy density, I like the fuel cell truck, at least that is more practical than the Semi with a 250 mile battery.Throwing away 80% of the energy when we need to make it ourselves will never fly.

Earlier this month, Toyota announced a deal with truck maker Hino to jointly develop hydrogen fuel cell trucks for the North American market. The trucks will get the Toyota Mirai’s hydrogen fuel cell technology and Hino’s vehicle body, with plans to deliver a “demonstration vehicle” in the first half of 2021. That deal comes after Toyota in 2019 announced a separate collaboration with Kenworth Truck to develop heavy-duty hydrogen trucks for North America.
“We’re at that tipping point,” said Andrew Lund, chief engineer of heavy-duty trucks for Toyota. “The technology has proven to be available.”
Many issues that are applicable today, but will be dealt with in the future. Another issue is simplicity - eVehicles use little or no oil for lubrication, and the emotors have basic 3 moving parts - the armature, and the 2 sets of bearings that support it. Electric motors are cheap, and extremely reliable. Consider how many electric motors are in your house that outlast the products they power, like garbage disposals, can openers, furnaces, and even the cooling fan in computer I'm typing on. How many parts are in an ICE? Hundreds if not thousands - just look at any exploded diagram of both - simplicity equates to manufacturing costs and energy usage, ongoing maintenance, and ease of repair.
Electric cars are about the same weight but battery will soon be incorporated as part of the structure of the car making it much lighter. No engine, radiator, transmission and so many other parts. Battery technology is advancing at a rate similar to Moore's Law.

I am not contesting that electric motors are much better in almost every category,
It is true that a battery electric does not need the Motor, Transmission, Gas Tank, ect, but that poor energy density eats into saved weight a lot.Electric cars are about the same weight but battery will soon be incorporated as part of the structure of the car making it much lighter. No engine, radiator, transmission and so many other parts. Battery technology is advancing at a rate similar to Moore's Law.
Future batteries, coming soon: Charge in seconds, last months and power over the air
Energy capture, storage and generation remains a vibrant area of research. Here we examine show of the research breakthrough in future battery tech
We will see. I am on my second EV now and have high hopes to own a Tesla pickup. I am retired and charge my car at home. Been a year since I filled the caddy with gas and parked it in the garage.
I was on the Hydrogen train a few years ago and thought the fuel source was inevitable, so I bought a bunch of Platinum since that is the preferred catalyst in H motors. Considering the subsequest investor reports, car manufacturer trends, and the metals price, its not on the radar; it looks like vehicular motivation is leap-frogging right to eM. Either way, H or e-, I'm on board.
And that 8 gallons goes over 400 miles because of the efficiency of electric cars over IC engines. When you burn something it produces heat more than anything else.
You better drain that gas in your Caddy before it turns to varnish and wrecks your fuel system. Yet another problem with hydrocarbon fuels. They degrade rapidly.
The average car is driven about 30 miles a day. I think the great thing about electric cars is that when there are millions of them parked at home or work and plugged into the grid we will be able to use them to distribute demand over time and not need as much on-demand generation. Also transporting and storing hydrogen would seem to be a logistical problem. Don't know that we could leverage much of the fossil fuel infrastructure.
Not at all it would go over 400 miles because of the efficiency of the fuel cell to convert the energy in the fuel
