Two men charged with spying for China

Sadly, but nevertheless, it is what is needed against every dictatorship.

It's the wrong bet, but when JCB made that decision they decided electric was good for small diggers, but the ones that do motorways needed more power and they needed to run for a whole shift without being taken out of action to recharge since large digger hire is costly business. The way it is with electric is it is always the battery which is the problem. You can get a 500bhp electric motor that is so compact it can fit to each wheel of a car and then you have 2000bhp with ms computer accuracy regarding torque. It is as close to perfect as you would ever want.  With batteries the main two issues are the cost and the energy density. As energy density increases it gives you larger parts of the overall market that can be achieved by electric. The highest bracket is commercial air travel which needs 1200wh/kg to be viable. So as energy density rises you start to see electric trucks and you can have electric boats as well. The story with hydrogen is you still have the Carnot limit to how much efficiency you get from your engine and how much energy you get is going to scale with the size of the engine as it does today. With batteries the energy density over time has increased far more than the extra power that can be got from a combustion engine because combustion engines are the result of 150 years of technical refinement, where batteries are a pretty new thing, at least the lithium ones are. Just the other day China published a paper in Nature for water batteries that can achieve 1200wh/kg. It's just at the lab stage right now, but I reckon something far more energy dense will be available in 5-10 years. If it were my money I would bet electric. You are welcome to do as you please with your own money. One thing going for China though is the amount of solar radiation per square meter year that falls on them is far more than with us. They are closer to the equator. Our advantage is north of the UK has some of the fastest wind speeds. Besides a UK government report said hydrogen was uneconomic in all cases except possibly for buses due to the economics of recharging time, meaning you need more buses. One thing you can do though is have detachable batteries so you drop the battery and jack up a recharged one into your bus or whatever.

So can farmers with Shotguns

Don't burgle farms then.... Simples.

Break into my home and attack me with a knife and I won't be held responsible for whatever I need to do in self defence.

And none that he wasn't.
You weren't there.

If someone broke into your home, would you not consider that a threat?

I know of someone who at gunpoint ejected a burglar from his property, a burglar who was armed with a knife and had threatened to use it, before discovering to his horror, that the owner was substantially better armed than he was and had both barrels pointed straight at him.

Now, in that case, the owner did not fire, burglar was at the bottom of the stairs and he was at the top.
Had the burglar advanced, he would have used lethal force.
And so would you, if you'd been in his shoes.

Not to be evil, not to become a murderer, but to survive and ensure your family survived.

When someone breaks into a home and threatens the occupants, if they are hurt, it's their fault, not the owner's.
