Does anyone take that sort or rubbish seriously? Anyone with the slightest ability to think rationally would see straight through this nonsense. "Nothing goes right for Tesla, it cant lower costs, build factories effectively, or launch its autonomous network" - Price target -$750. Yeah, right.
I have been taking a closer look at TSLA lately, and I can see a case for the company being worth a lot more than its current share price in the future.
That wasn't the point i was challenging, its people so caught up in emotional speculation that they can't spot the gratuitous ramping from so called analysts. As I said its arrant nonsense to suggest that if nothing goes right for the company its shares will be worth $750.
The battery car will die ones synthetic co2 neutral fuels are released. A fuel that contributes no extra co2. To me that’s more then what a battery car dose and you can fill it up in any car you drive now and you don’t need to turn your engine and your car will run better and cleaner. Diesels will no long have partial filters before there will be no Sulfur in the fuel.
How are these fuels made, are you talking about hydrogen based fuels that are bonded with CO2 to form longer chain carbon based fuels? if so these fuels have a place, but they can't compete with charging batteries.
The energy lost in electrolysis to produce hydrogen, run compressors, bond the Co2 etc is massive compared with the 5% of so energy lose to have when you charge a battery.
and then after you have lost all that energy to create your liquid fuel, the combustion engine itself is only 30% efficient compared to the electric car being about 85% efficient.

There is some very basic physics which makes it clear an electric motor and a quality long life battery system is far more efficient than an ICE.
The hydrogen fuel cell model that creates electricity from hydrogen (or ammonia.) is an alternative. But it depends on the cost of hydrogen and cost effective transport of hydrogen in some form- preferably not gaseous.
I have had an eye on Alkaline Fuel Cells for a few years as a producer of very cost effective fuel cells that don't even need particularly clean hydrogen. They have a commercial product that seems to make good economic sense.

Gas to liquids cheeper then oil base fuels
Why would you want all the inconvenience of a battery car if you had an internal combustion engine that burnt zero emissions.
Petroleum is already the most efficient means of energy storage when it comes to density compared to battery.
Take for a example 1 litre of fuel can run a 100Kw engine for an hour give or take. That’s 100K hours of electrical energy. Now try and find me a battery in the size of a litre that will produce 100KW hours of energy ? There is no such thing. Not even close. Maybe 10Kw hours but definitely not 100. So yes liquid fuels are still more efficient.
Batteries are not energy. They still get power from fossil fuels in one way or another.
If you clean the fuel up you have clean engines.
The more emission restrictions we put on current burning fuels the more pressure it puts on companies to produce synthetic fuels.
Fuel that is made up from renewable means of gas and carbon capture. Hydrogen is always burnt off at gas refinery’s as a by product. It’s an abundant resource. Carbon capture proses powered by natural gas technology. There you have it. A liquid fuel that’s fully co2 neutral. I don’t see any battery car doing that ? No raw materials mined, no waist, it’s all recycled..
Oh and it also feeds the industry sector as a diesel and aviation fuel lol so yeh I don’t see battery powered planes any time soon.
Fact of the matter is cars are not even the biggest concern, you need to fix the transportation industry such as the trucks, trains, ships, busses. Just because you have a Tesla that don’t mean anything. How did you think your new Tesla is going to arrive at your dealer?
Fix the fuel first not the car. There’s nothing wrong with the engines, it’s the fuel.
Your thinking so small
The fact that formula E have to swap cars for a refuel is just a pure joke
And another joke is they power there cars using generators using liquid fuels that came from renewable means.
