You get none of the benefits of regeneration either. Suggesting they are a gimmick.
Not sure I follow what you are saying there. Are you saying regeneration is a gimmick which seems unlikely or just in the case of restomod type use wich if true is a bit ok, so what.
The best zero emission proposal I have seen is using liquid air to power a turbine. Air can be compressed using excess power from solar or wind.
I have seen that suggested for energy storage for grid leveling, pumping air into underground spaces and then using the pressure to drive turbines when required. But never for vehicle use.
I meant the restomod as the gimmick. Changing an existing car has lots of challenges. EG. Weight in the wrong place resulting in poor handling - or as TVR would say an exciting driving experience. :P
Would need to look up the data, on the power densities of a battery or compressed (liquified air). I know when we went around some studies at work, matching the power density of Jet fuel is a very hard challenge.

I would think one of the problem of using liquid air would be the latent heat of evaporation would need to come from somewhere to get it into gas form.

Another consideration is safety in the event of an accident.
Batteries, capacitors, flywheels, compressed gasses, can all potentially release their stored energy catastrophically.
Petrol is relatively safe, it will burn, but to get a big explosion you have to turn it into a vapour and mix it with air.

All vehicles sold in EU must be 0 emissions by 2035…i thought this was already put into EU law?

Yes, its the combustible ratio of gas to air. For methane pit deputies tested it every day and it was 8% gas to air when it exploded. Petrol will have a different ratio, which I dont know.

But in my industry we are taught about different ratio araound the room, it wont be even. If the spark from the lightswitch that causes the explosion is in a portion of the room at the riht ratio, boomb. If it is where there is more gas, no boom. So we need awareness that although opening doors and windows is the advise we must give on the phone, that can bring the ratio to the explosive ratio just as conversely not opening them can.

Welders feel safe when fuel tank is full.

Zero emissions? LOL oh they mean ignore the emissions up to the point you take delivery.

Yep, its almost as if individual countries in the EU get to decide what gets passed into law or not :-). Ironic how we don't have a say in it anymore now we have "taken back control".

I’ll be fine. Heres the plan, get a couple of counteies who havent even signed the kyoto agreement to manufacture all our zero carbon emmissions in its use in India and China to shut up the people glued to the M25.

A short video about synthetic fuel and the EUs revised ruling on it's use in the future.

I did notice that part of the procedure for making synthetic fuel was using renewable energy to make Hydrogen. :wink:

Indeed but they are not transporting it or storing it offsite :wink:

The video failed to mention the EU already had a clause that any manufacturer making under 1000 cars a year is exempt from the new ruling, so the exotic and specialist manufacturers could continue to produce ICE cars.

In reality I suspect E-Fuel will remain a niche option, it's coming to F1 I understand in 2026 and is already used in the WRC series... it will keep all those old classics on the road but for the mass market the 4x greater electricity required to produce it will limit its market potential.

Yep, I don't think that's making the point you may think it is. Don't think anybody questions that Hydrogen is part of Hydrocarbons

A new battery type.

Bullshit or advanced technology ?
