Davy51 Posted July 15, 2021 Report Share Posted July 15, 2021 Following on from the latest announcements about battery power for vehicles & hydrogen power for aircraft & road vehicles ,what are the thoughts on the subject from the sagacious grumpies on the forum ? I'm wondering more about ,if water is the source of the hydrogen , how will the extra oxygen produced affect the atmosphere ,greenhouse gases & global warming etc. Is the bi product of surplus oxygen from hydrogen production likely to be the antidote to so called climate change or will too much oxygen in the atmosphere cause other problems ?

asperity Posted July 15, 2021 Report Share Posted July 15, 2021 The atmosphere has 209,500 ppm of oxygen (about 21%). CO2 makes up 400 ppm (about 0.04%). Humans need a concentration of between 19.5% and 23.5% to stay healthy, below 16% is generally fatal. We can breathe 100% oxygen for short periods (in hospital for example to aid recovery) and astronauts have breathed 100% oxygen at low pressure for up to 2 weeks. I should imagine that, the same as everything else, the planet would adjust as it always has. Quote Link to comment Share on other sites More sharing options...
Davy51 Posted July 15, 2021 Author Report Share Posted July 15, 2021 We do have an abundance of water to produce hydrogen so we should all have long & healthy lives then. Quote Link to comment Share on other sites More sharing options...
Bill Posted July 15, 2021 Report Share Posted July 15, 2021 I wouldn’t worry too much as it looks like hydrogen powered vehicles will be limited to specific applications where conventional batteries wouldn’t be suitable. Nobody bought Betamax recorders back in the day, not because they were in any way inferior but because VHS had stolen the lead and was far more common, and it’s much the same now with our electric cars. I’m currently trying to save the planet by building a direct solar water heater suitable for the UK climate. So far so good and hopefully my new and improved second version should be even better than the first. The wife thinks I’m bonkers but at least it keeps the grey matter ticking over.

asperity Posted July 15, 2021 Report Share Posted July 15, 2021 You'd better hurry up Bill, you've only got 12 years to save the planet......................Wait!! It's now only 8years? Oh no, hurry up Bill there's no time to waste 🤣🤣 Quote Link to comment Share on other sites More sharing options...
Observer II Posted July 16, 2021 Report Share Posted July 16, 2021 Seems an appropriate time for the Boomers to pass the baton onto the Millenials, and say "I'll leave it with you" (titter). Super hot heatwaves in N/W US, Biblical flooding in Germany; and according to NASA, a post 2030 Moon wobble lasting 18 years, that will bring tidal flooding throughout the globe. Add to this WHO predictions of yet more pandemics; then violence and wars caused by mass migrations, and you have a cocktail of woes, for the snowflakes to suck up. Beam me up Scottie. 😉 Quote Link to comment Share on other sites More sharing options...
asperity Posted July 16, 2021 Report Share Posted July 16, 2021 Try and get your facts straight Obs. The moon has a wobble on a cycle of approximately 18 years, something that astronomers have known about for centuries, so why they've decided that this scare story is something new is the mystery. Heatwaves and flooding? All part of climate change, something that has always happened and always will, but the media never lets a good scare story go to waste.

Bill 😊 Apparently Beetamax was a better quality system ,, but shops and rental stores tended to store 85% VHS and eventually it just died out.

Quite true latch the problem was that it was expensive for the films to be put on it. VHS was a lot cheaper to make and copy the films onto despite inferior quality. Mind you most tv's back then would be hard pushed to show the difference. Quote Link to comment Share on other sites More sharing options...
Observer II Posted July 17, 2021 Report Share Posted July 17, 2021 I've still got an old VHS camera and loads of films, that I now can't watch. 😠 Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted July 17, 2021 Report Share Posted July 17, 2021 can you not transfer them to a hard drive and then onto cd/dvd? my tv records onto a hard drive or a memory stick and will play the odd film i have transferred over, provided it is in the right format.

Observer II Posted July 17, 2021 Report Share Posted July 17, 2021 Believe there are folk who can transfer them to DVD(?), but I've lost track of what gadgets I've got or what they're for - basically I'm still living in an analog world. 😉 1 Quote Link to comment Share on other sites More sharing options...
Bill Posted July 17, 2021 Report Share Posted July 17, 2021 The point I was making was that hydrogen powered cars are a bit like Betamax. They won’t be bought if battery charging points are 100 times more plentiful than those for hydrogen. But technology has a habit of moving on and maybe at some point in the future hydrogen will become the primary fuel. But for now, batteries are way down the road while hydrogen is still stuck on the starting line. Bill 😊 Quote Link to comment Share on other sites More sharing options...
Davy51 Posted July 17, 2021 Author Report Share Posted July 17, 2021 I live in a terraced house & there are more cars than houses with potential charging points . We would have to operate a shift system. Quote Link to comment Share on other sites More sharing options...
Observer II Posted July 18, 2021 Report Share Posted July 18, 2021 Has anyone totalled up the cost of all this to individual households ? New EV's, gas boilers replaced etc. Plus, we'll all have to pay more taxes in order to pay for the pandemic spending spree. All rather depressing.

Davy51 Posted July 18, 2021 Author Report Share Posted July 18, 2021 Sure is ,Obs. One thing is for sure is that sustainable energy will not be cheap even though it will be coming from within the earth just like gas & i can't imagine the appliances of science to use the new energy will be cheap either.

Observer II Posted July 18, 2021 Report Share Posted July 18, 2021 Well, if the latest Extreme Weather Events are anything to go by, were already past the point of no return. Heat waves in N/W USA and floods in Germany - at least they can't blame it on the RAF this time ! 💀 Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted July 19, 2021 Report Share Posted July 19, 2021 Don't mention the war obs......🕺 Although it does make a change from flooding on the African continent. perhaps they will have an appeal there to send aid to the flood stricken Germany.....🤭 Quote Link to comment Share on other sites More sharing options...
Observer II Posted July 20, 2021 Report Share Posted July 20, 2021 Seems we have our own heat wave now, so all the lemmings are flocking down to the beach to share their covid viruses; and welcome the hundreds of illegal migrants arriving from France - JOKE. 😷 Quote Link to comment Share on other sites More sharing options...

Observer II Posted July 20, 2021 Report Share Posted July 20, 2021 Government totally lost it - they've neither the legal powers or political will to do what's required to stop this in it's tracks. Meanwhile, the Australians are just towing them back whence they came. 😠 Quote Link to comment Share on other sites More sharing options...
Davy51 Posted July 20, 2021 Author Report Share Posted July 20, 2021 I can't help thinking that it would save many lives if the government charged the people traffickers a fare for these boat people & provided an organised ferry service across the Channel. I am surprised the woke brigade haven't already demanded this of HMG under health & safety measures. 1 Quote Link to comment Share on other sites More sharing options...
Observer II Posted July 21, 2021 Report Share Posted July 21, 2021 With 5 million EU migrants plus over 2 million illegal migrants - our population has increased by 10%; making it the most densely populated country in Europe. The solution is to take them back asap; even if it means dumping them on French beaches. 😠 1 Quote Link to comment Share on other sites More sharing options...
