I wasn't talking about diesel engines. Why would I when the thread isn't about them? 'IC' refers to internal combustion which covers petrol and diesel types as well as those running on alternative fuels like LPG and so on.
Depends what you mean by a failure. Cats. are very effective on some types of IC engines, emitting cleaner air than they burn, in terms of NOx, etc.
But if so, he was wrong. New thinking is needed. Not drivel from the past.
The age of cheap fossil fuel is almost over. We must use what remains as sparingly as possible to set us on the new renewable technology. Which age need never be over. And won't poison us or our children.
Er no, they weren't impossible harry. Thass the point. None of these breaks any physical law. Possibly, if some natural philosopher in the
18thC was asked about some of these, he'd might have said "May be possible but we don't know enough about nature to say one way or the other" but that's *all* he could have said. A 100 years or so later he might have said "Yes we broadly speaking understand how to do this but we can't build a vessel strong enough (or light enough, or whatever) to make the item in question a *practical* proposition.
After all, planes flew in the early 20thC. Didn't mean that the following Tuesday fortnight they'd be rolling out the A380. Equally, only a fool might have said that heavier-than-air flight was impossible. Unless they believed that birds flew by magic, of course.
The difference is that too many of today's idiots believe in magic or that a bit of development ought to allow us to have solar panels that could go on the roof of the car or a plane's wings so that the car/plane needs no other energy source.
Slavery died out in the first world long before there was any cheap fossil fuel.
Yes, technology was the main cause of the demise of slavery in the first world.
No. Its still the reason that slavery isn't useful anymore and always will be, particularly with technology. Even domestic slaves have no real use now that we get technology to do what we used to have slaves do.
It rarely came by accident in the past too.
They always did and that is why humans do a lot better than animals.
No one has no education anymore.
You are unlikely to invent anything even with education.
It still happens, just differently, most obviously with apps today.
There's no point in using slaves if it's cheap enough to employ people, and that's what happens - see eg construction workers in the middle east, lots of China, etc.
It's not technology which has replaced slaves, it's other forms of abusive labour.
Norway has major social problems. The people largely work in non jobs for the state and cannot afford to use restaurants or bars. The exchange rate is unreal.
