Unless someone comes up with some new miracle battery, electric cars are never going to make any sense. They can't handle cold weather, and they can't stand hard work.

Gasoline engines generate large amounts of heat. That heat is mostly waste heat, but it can be used to heat the cabin of the car in winter. Electric cars do not generate waste heat, so heating the cab draws power from the batteries, running them down. In really cold weather, you need a lot of heat for the inside of a car.

Electric cars don't like to tow anything heavy. And they don't like wind resistence. Both suck power from the batteries at a rapid rate. An electric car that might go 200 miles if it isn't towing anything will only go 80 miles if it is pulling a trailer. Also, the faster a car goes, the more wind resistence. A car that will go 200 miles at 60 MPH may only go 120 miles at 75 MPH.

It all comes down to power. The batteries in electric cars just don't hold enough of it to allow them to compete with gasoline powered cars. And we're not even considering here how long it takes to recharge a car's batteries. We're talking 30 minutes for a partial charge that might give you 80 miles of range. Electric car makers always over-report their cars' range. Always.

You're missing the forest for the trees here.

The bigger problem is the battery tech will catch up.

And eventually it'll either be mandated or so many regulations, taxes, fuel fees, and policies will be passed, that the culture itself will move away from gas and diesel powered vehicles.

Like owning machine guns, only the really well-off, the ones with no incentive to fight, will own and use them.

and because of this trend, the next step, implemented in tandem, will be the full ability to remotely monitor all aspects of travel. The state or its affiliates in wallstreet, owned through blackrock moneyprinting, will control travel, be able to shut it off for any reason, or restrict and limit its range, time of use, and access based on any factor (including social credit), at any time.

Good luck mustering a militia when 90% of your guys can't afford, in practice, the $25k in operator costs and fees, yearly, to own a diesel or gas vehicle.

Current battery don't love heat to. In hot climate you must cool batteries. However, electric cars is not bad idea per se, but THEY push these shit although technology are not ready to carry all real world demands. Add to this that electric cars are all but no ecology friendly. Batteries have very limited life time. Manufacturing is one of most envirnoment harmful process. Also recycling is limited, also very harmful for envirnoment .... and most manufacturer ( including shitty Tesla ), don't allow owners to change only cells which are die... no, no, you must buy complete battery pack and waste pack which have sometime only one dead cell.

electric is a nice trap

just look at the power density of diesel compared with a fully assembled lithium battery, to be clear, ho much energy can you "extract" from a Kg of diesel and from a Kg of a fully assembled battery ?

It is important to say "fully assembled" since tha raw lithium is useless if not into a bully assembled state.

~30% efficiency, and around 40MJ of energy in a Kg of diesel. That means ~700hp/kg of fuel per hour, at a rate of 100kg per hour, the engine, fuel system, lubrication system, forced induction system, and cooling all take up space and add weight. Engines are the heaviest part of the car. With an electric car, the motor drive, and cooling system are more compact and energy dense than a combustion engine, the battery storage is not however. So there is a tradeoff.

If you could have the same energy density as fuel, and the energy density of electric motors, you'd have an ideal scenario. Hybrids try to get there, by using fuel to run electric motors and batteries. Turbine engines are prohibitively expensive, both to manufacture and design, so that wouldn't work on a car. It's a tricky scenario for sure.

I agree with Musk, that it's overall cheaper and more efficient if everyone gets their energy from the same source.

To put into perspective how expensive it is to design and manufacture turbine engines. One reasonably intelligent engineer will collect low 6 figure salary just to work on one compressor stage in a 5 stage compressor. He works with an entire team of people to make sure his tinkering doesn't fuck up everyone else's tinkering and vice versa.

I love how you did not do the comparison using joules or watts hour, actually you did not compare them...

Speaking of engines, you "think" making an electric motor is easy ? think again.

Not only you have mechanical issues, you ALSO have power electricity issues (you did not have them with fuel engines)

I crunched the numbers and they are not pretty, at all.

You can convert hp to watts, I love how you missed that, and think you got me. Fuel is dependent on flow rate, and mass, as the potential energy is fixed. So in order to compare energy over time, you simply have to know the fuel flow rate and the efficiency of your engine and the energy density of the fuel. With electric motors it's a bit more complex, because the flow rate is dependent on voltage, current and resistance. Efficiency is much higher with electric though, 80-90% efficiency is common.

As far as electric motors, I never said it was easy, if it were, any asshole could do it with a 3d printer. As an engineer I understand how engineering works, or I wouldn't be one.

With combustion engines you have other issues, I've been working on combustion engines for a long time. By comparison, my understanding of electric motors is limited. Combustion engines are much more my bread and butter, anything that deals with air really.

The electric grid can barely handle the load as it is now. They already have rolling blackouts and brownouts during the summer from just air conditioning use. What will happen when a couple million electric cars get plugged in to recharge?

You're wrong.

People were buying Teslas and SUVs because that's what people want here. Even when gas was cheap.

damn kikes making me drive a prius again

Don't forget that expensive vehicle you now own will be worthless scrap. The entire electric grid has to be replaced to handle electric cars. Thousands of new power plants built. Or maybe magic will be used.

Man i remember when it was the other way around, when gas companies were suppressing the electic vehicle on forums like these.

Oh you mean oil companies have been blamed for all the ills of the world by liberals that wrote those TV shows like The Simpsons? That's so strange, that the TV would lie to us now, but not back then.

Well it's not like oil companies don't have a ton of power considering that the us dollar only has value because foreign nations were forced to buy oil in USD. Now Russia is playing that game with the ruble and what should be a dead currency has only been strengthening due to playing the same tactics. Just because the push to electric shit is liked and happening now it doesn't mean oil companies were above suspicion

Let's just deal with reality, everything you use, and depend on in the world is thanks to oil, energy companies are very fair.

All the top brass are conservative white men, they understand that oil is a finite resource, and that vital resource is the lifeline of everything we take for granted. That's just facts. Work for an oil company, I guarantee you will be treated better and more fairly than any big tech company. Why do you suppose conservative white men run these companies, and they create good quality of life for their employees? Meanwhile Amazon has crying closets, and is ran by liberal commies, who is doing right by their people?

You say that like there's a glut of electric cars they have to get rid of. There isn't, they can't make enough of them right now.
