Electric cars

Unlike the Tesla dealers, who are eager to take your money but don't deliver the car

who has the biggest waiting time, Tesla or Morgan?

Irrelevant. Morgan will quote you x weeks, and then deliver on time. Tesla (so far) don't.

Corrected that for you.

Mates got an I8 for an extended test drive.
Hoping to get taken out for a spin Having seen a couple in the flesh,pretty motors!

I had the Chargemaster one fro a week, its a real hoot of a car. Problem is being used to an EV and not burning fuel, having the i8 and using £350 in Petrol in a week was scary. But did take it all around the UK.

It's about time a government somewhere in the world decided to use a bit of joined up thinking.
Build nuclear power stations that are designed to produce electricity and hydrogen. Also mandate that all new public busses must use electricity or hydrogen fuel cells. Then force all coaches to follow. Then force all taxis to follow. The infrastructure to distribute hydrogen will naturally build up. Subsidise hydrogen fuel cell cars. Then ban petrol and diesel engines. Hydrogen fuel cell cars will take off and all pollution from ICE will end.

Hydrogen fuel cells produce zero pollution but their advantage over battery electric cars is that you can stop at a fuel station, pump in more hydrogen and off you go. No waiting around to charge your car. The range would be unlimited, just like a car. Everyone would be willing to switch eventually.

Problem solved.

But it requires a government to do this because it's currently stuck in a catch 22. There is no infrastructure for hydrogen production and distribution. It can only be produced cheaply at very high temperatures, which is why you use the new nuclear power stations. Hydrogen fuel cell vehicles are too expensive because there is no scale. There is no scale because there is no cheap hydrogen.

It's not quite that simple.


Hydrogen has a very low energy density by volume.
A litre of compressed gaseous hydrogen contains 0.5 to 0.75kWh energy depending on pressure (and that's at 2-300bar, 3000-4500psi).
Liquified hydrogen is much higher, 2.3kWh/l, but there are fairly obvious safety issues with storing, transporting and dispensing liquids at -250degC.


Petrol and diesel are each about 10kWh/l.


So to get the same energy as a 50 litre fuel tank, you're looking at around 20x the volume (plus substantial pressure-vessel overhead) for the safest of those options. And those kind of pressure vessels require regular testing and certification.

But it requires a government to do this because it's currently stuck in a catch 22.

It requires more than "a government". It requires international co-operation, probably at least continental-level, maybe even global-level. I'm not sure even the EU or US alone would be sufficient.

no government will back leccy cars, the revenue from diesel/petrol is too good to lose, the oil companies havent rushed to install chargers for the same reason

car builders wont rush because mainly their business isnt building the cars, its making the piston engines, GEC already make enough electric motors, BMW alone have capacity to build 1000's of piston engines a week... why risk it

How much is a Tesla 3 going to cost?

Road pricing is the obvious solution.

And is there a good reason nobody else has?

You're forgetting that many manufacturers are in joint ventures to build engines, or simply buy them in from other manufacturers. Opel buy Fiat diesels in. Mercedes buy Renault diesels in. Ford and PSA share diesels.
