Some don't though. I remember a conversation I had with my grandfather (who used to repair TVs) in the pub when he was in his 80s, somehow we got onto talking about the new stuff that was coming out. HD wasn't really a thing yet - and he commented it didn't seem worth getting a large TV because how visible the lines would be (and additionally, it'd be even worse for people in NTSC countries with about 100 fewer lines).

It's happening anyway, every last joule of that tidal energy is already being used, it's just being used up by crashing up and down shorelines rather than turning turbines. Tidal power merely extracts some of the energy that would have otherwise been dissipated on the shoreline, so there's no net effect on the moon anyway.

> Now connect it to a generator and extract enough power such that it doesn't accelerate any more, but doesn't slow down

This here is the impossible bit. Just because you can /momentarily/ extract 6-odd kw at the shaft, it doesn't mean you can keep doing it forever. You may find that any more power extracted than just the friction in the bearings will slow your hypothetical wheel down.

1000Nm torque doesn't say anything about the power you can continuously extract.

You don't bankrupt a company by selling its shares.

You might make its share price lower, which in some cases might make it a tasty takeover target, but the price of a company's shares on the secondary market doesn't affect in any way shape or form the running of a business. You're only selling your ownership stake in the company to some other person.

With a well run company like Shell, if you divest shares and the price of the shares go down, it will be somewhat self correcting. The dividend yield will go up - the business's viability hasn't changed, so the dividend remains the same but you can buy into that with a lower share price - making the company more attractive to people who don't have a problem with owning shares in oil companies - thus stopping the share price from falling very far.

The only way you're actually going to hurt Shell is for everyone to stop buying their product. That isn't going to happen any time soon. It might happen over the long term, oil usage vs GDP has been falling for some time now. But selling Shell shares isn't going to put them out of business since it literally doesn't affect them.

Britain is not the best comparison for Europe. First off, Britain is always a laggard when it comes to clean power - it was a laggard just in cleaning up its act with sulphur emissions with the coal plants. The UK is also not really Europe and generally doesn't subscribe to Europe's more progressive policies when it comes to energy. Expect a lot of backsliding on this once Brexit is complete and EU regulations are no longer pulling the UK kicking and screaming into the 21st century.

It reminds me of Anthony Burgess's novel A Clockwork Orange. He realized that any real-world slang would soon become out of date so he invented his own slang language, Nadsat, for the characters to speak. Of course, this can be taken too far, where the made-up language comes to dominate the work with the story being an afterthought. Like some of JRR Tokien's works, for example. In fact you could say that TAOCP is the LOTR of computer science.

See what Joel Spolsky wrote:

If you show a nonprogrammer a screen which has a user interface which is 100% beautiful, they will think the program is almost done.

People who aren't programmers are just looking at the screen and seeing some pixels. And if the pixels look like they make up a program which does something, they think "oh, gosh, how much harder could it be to make it actually work?"

They aren't that fragile. My Dad has my old iPhone 4, it's never been kept in a thick plastic or silicone case, and it still looks nearly as good as new despite now being 6 years old (and on its original battery!)

My iPhone 6 which replaced it, when it came out, has never been in a case. It rattles around in my pocket with everything else in there. It's now 2 years old and still looks practically brand new despite never having been in a case and having been dropped once or twice.

They aren't anywhere near as fragile as people think. They are actually pretty tough.
