No one has any idea how to deal with the dead lithium and it cannot be revitalised. We're running into the same problem as with petrol.

There was a comparison years ago between an early Prius and an old Volvo. I believe 1 Volvo be built and driven around the globe once before they produced the same amount of CO2 as the production of 1 Prius (that's probably not correct but whatever it was, I think the Prius needed to drive 400,000 miles before it broke even on CO2). Almost all of the CO2 relating to the Prius was to do with the battery which is a fraction of the size of the latest batteries in BEVs.

Day to Day, Electric is way better than petrol/diesel. Also, I get my Electric from a sustainable energy company so I am on the greener side already.

As for the water situation it certainly won't add more water to the planet but it shouldn't lose any either. I'll do more reading up on that though

Keep us updated Cav . I like your posts, honest, fair and informative ( I dare nt say factual anymore )

Electricity can be produced with very little in the way of emissions, in some cases the only energy used is to manufacture the equipment needed to produce it. It just harnesses the sun’s energy which will outlive human beings by a long stretch.

Whatever the future is it will have to be energy produced from a natural, renewable, low emission source.

The problem of CO2 production in manufacture is the same regardless of the energy source. ICEs rarely last more than 100,000 miles. Go to Amsterdam and there are Tesla taxis running there with over 300,000 Kilometres on the clock.

Sales of electric vehicles have skyrocketed over the last few years. Fully 1-in-250 cars on the road are now electric!!!!!
We're saved.

IMO, we'll all be driving Hydrogen cars in the next 20 years. The only emission is water, the hydrogen can be broken at sea powered by their own windmills, pumped in gas form to the shore, compressed to liquid and shipped to fueling stations around the country. They drive the same as internal combustion and you refuel in 2 minutes. It will be MUCH cleaner for the environment (from start to finish) than electric cars and so I think I'll be waiting for that. Until then I'll stick with what I know and stay with diesel.

Fwiw I'm also very much a fan of the hydrogen fuel approach, however containing the element with the smallest molecular mass in the known universe presents challenges.
Also I would wish (read :dream ) that conversion of our current petrol powered vehicles may be feasible.

Surely the water being produced is already catered for Jon, by our road drainage systems that cope with rainwater (in far greater volumes than such engines would produce).?

A hydrogen fuel-cell vehicle produces about the same amount of water per mile as it's petrol-powered counterpart...give or take...according to the US Department of Energy.

Hydrogen is a b*tch to contain and highly flammable when mixed with normal atmosphere. As little as 4% N2 mixed with air is flammable.

We had a plant at the refinery that produced hydrogen as a byproduct and we were always struggling with N2 leaks and minor ignitions.

There will be a practical method developed to make it all work. What I worry about is the maintenance and integrity checks carries out during its life on everyone’s run about.

we've been working with hydrogen as fuel in rocketry and missiles for over 75 years and even NASA still have trouble containing it satisfactorily , I don't think it'll be solved anytime soon . The perfect solution would be to carry water as fuel and convert it as required but current technology is unable to do this due to the large power consumption required .

I'm a firm believer that Hydrogen fuel is a better option than battery power for many transport uses, so if this resolves that major hurdle it could push the beginning of a significant new direction.?

I like the sound of that but it also sounds like $$$$$.

To me it seems like this article is hating on a fuel load weighing 4-5kg for 300 miles of driving. The same range in a petrol car would weigh 40kg.

I watched something about the use of cars. Before the Model T came out almost a third of cars were electric.

Doesn't hydrogen production use a huge amount if fuel in the first place?

A few times this week, I have sat out in the garden at lunchtime getting very warm in the sun, and then in the evening turning the fire on because it's gone cold. It makes no sense to waste all that free energy in the day and then burning up precious resources at night. That has to change.

As I scraped the frost from my screen to go to work this morning, I wondered how all electric cars are going to perform in winter.?
As well as the huge electrical load it takes to defrost (and keep defrosted) screens in low temperature environments, what about warming the passenger compartment.?
We all take for granted our use of the waste heat energy from our ICE (see what I did there ) to warm us. AFIK there is no waste heat to harness in a modern all electric car.??

Personal vehicles will not be the main mode of transport in 25 years time. I’m pretty certain that is the plan of those in charge.

In 25 years?? - I think there'll be more cars than ever.
There's going to be more people for sure. cities will be larger than they currently are, and mass-transport is always playing catch-up in that regard. Proportionately the balance might shift somewhat towards public transportation, but I doubt we're going to see some massive revolution in how people value or perceive car ownership.

Short answer, a very efficient heat pump.

all the sales people I know who own one say they are terrible in winter,the range is very limited and the accessories turn off
