Another reason to keep my petrol powered RAV.

To be honest it wasn’t that successful with the Hindenburg airship !

Not saying that bloke is wrong but there are sooooo many opinions on the subject it’s hard to know who or what to believe. I doubt Toyota would be heavily investing in a dead duck. Me I know nothing 👍👍👍

The hydrogen wasn't the cause of the hindenburg disaster, i beleive that it was something to do with the mixture of paint on the skin that made it highly inflammable, once that ignited the hydrogen also went up. Causing the fireball. |

An interesting point passed in my direction a couple of days back is the validity of generating electricity offshore not only to power homes but cars as well . Unless we generate green electricity for cars at least then there is no such thing as a green car . Anyone who thinks driving an electric car on normally generated electricity is doing so with no carbon footprint is not with it .
We live ina crazy uncertain world where conflict is with us daily . If we get involved then the offshore generators are sitting duck targets . So we cannot surely do away with the heavy polluting generating facilities we have now .

If we get involved then the offshore generators are sitting duck targets . So we cannot surely do away with the heavy polluting generating facilities we have now . The theory is that once we are generating more green electricity than we can use on a minute by minute basis, we use the surplus to generate hydrogen from water. We can then use the hydrogen, in conjunction with a hydrogen fuel cell, to generate electricity again either in a car or in a power station to put power back into the grid. The conversion from electricity to hydrogen and back to electricity again is fairly inefficient but it is a sensible way to store spare electricity (until we develop 'magic' battery technology). If the crazy, uncertain, world gets bad enough it's not just offshore generators that are sitting ducks - all of our cities are too - but I'll conceded that they might make tempting targets for terrorists. Either way, we need a mix of power generation options - including cleaner fossil fuel options and nuclear along with the greener options. |

In the event of European war we have defences that to some extent protect the mainland. Obviously we only have so much but something. The sites sat out in the sea are what I meant as sitting ducks. We’ve witnessed attacks on infrastructure in Ukraine and Gaza on infrastructure. Cut the power and it’s very difficult to function. It’s kinda scary but it does raise the point that we have to have significant onshore power production and hopefully defended . Keeping ICE cars going would be much easier than electric ones of course. |

The UK is not self-sufficient for crude oil, diesel or jet fuel, but meets its needs through a diverse range of import sources as well as indigenous production." (2022) So, OK we don't need to bring tanker loads of oil ashore to produce petrol, but the well heads out at sea are just as vulnerable as offshore wind farms and both need pipelines / cables to bring the stuff ashore. But let's not get too morose - we live in a very depressing century ...  |

But let's not get too morose - we live in a very depressing century ... Storing fuel in liquid form is easier than electricity. Especially at home. Sorry for the rather morose debate it’s the automotive part I though was interesting. Especially the provision of electricity in bulk ( if that’s the right word ) I mean we keep a generator here plus some fuel in case the grid drops out….. It used to do that but not in the last 3 years but it’s a point 👍👍 |

We still have plenty of coal - Maggie T made sure of that.

I believe they are digging coal in the north west to use in the production of steel. They keep quiet about if cos the environmentalists will play up. Don’t wanna upset Greta eh ? |
