I look forward to the operators tearing out their own eyes as they catch me sunbathing nude.

As a child I could knock a conker off a post around 100yds away with a sling in a couple of shots. Cost me a fortune in marbles practising but now I wonder if I could use conkers to take out drones! They shouldn't cause too much trouble on the way down - the conkers that is!
After I stopped laughing when I read Ayn Rand I thought no-one could really be stupid enough to try anything like that. I was horribly wrong. However it is only a matter of time before even the most hardened Rand fanatic realises that even a badly run state is a lot cheaper and more efficient than any Randian delusion. I just hope we dont get to test it out here.
I was under the impression it was more of a safety thing - you dont really want to be working on some wires having isolated the rest of the grid mains to be fried by someone's PV.
I have PV and we frequently have mains power outages here* and it does piss me off that I cant have a cuppa when my PV should be kicking out enough. I have looked into some form of isolation and then using another inverter to start the PV but its surprisingly expensive to do it properly.
You can get stuff for totally off grid working but I've not been able to find any that would work in both situations.
I did work with a civil defence group some years ago and it is surprising just how vulnerable to grid (and hence the country) is to terrorist/enemy attack - correctly implemented renewables make it vastly safer.
*lightning seems to bugger things up a lot but farmers with forklifts seem to take out a lot of cables too.
Even now hoses are falling into old mineshafts that are less than 200 years old and forgotten about. Given that some parts of nukes will still be capable of killing people in millions of years safe waste management could actually use more power than the stations ever generate*. Interestingly this is a charge frequently aimed at wind despite even sea based turbines paying back their CO2 debt in less than 9 months now.
*When I studied nuclear engineering at uni I got concerned about waste and was surprised by the what I would call a brexit like belief that it would be all sorted out later. Given that this stuff will still be capable of wiping out everyone in a city the size of London in 100,000 times longer than the existence of civilisation I do feel a little more attention should be paid to it and the potential cost for future generations.
They would use it as an excuse to release some radioactive gasses as they may have dont during the Chernobyl event, The Guardian printed a map of where the radiation from the reactor was deposited and there was a very suspicious plume in the Cumbria area near Sellafield.
No nuclear power is not. It was one of my major courses at Uni and at the time I asked my lecturer about a possible problem and was told it was unlikely to happen. It has since happened more than once and if terrorists were to understand what actually happened its surprisingly easy to make it happen again. You can do it right and prevent it happening but nuclear is already pretty much the most expensive source of electricity without taking into account waste management and this would make it safe from the problem I wont mention it detail would make tit twice as expensive at least.
PV even in the UK, for the price of one nuke, can provide 60GW peak load and provide more power than the nuke would ever deliver and not produce waste some of which will require 2 million years of management.
Offshore wind is already so cheap as to not require any subsidy and land based, should a government be inclined to allow it, would be near half that price - 20% of Sizewell C's price - assuming it is ever completed.
Thorium seems to be put forward as a possible solution but the fact no-one is investing serious money in it suggests there is a problem with it that is not generally known.
We made a set of chips once and they all worked perfectly in testing. Once packaged one of them refused to work. Turned out that one had a new component that only worked when it was illuminated. ISTR the demo package had an unpackaged chip and a light bulb to make it work while we sussed out how to get cct to work in the dark along with lots of whistling.
A few years ago my local exchange said it was going FTTC and I was delighted. There was an underground box in car park/gravel store that the engineers referred to as the cabinet and connected around a dozen or so local houses. A fibre was laid in the road and ran up to near where this 'cabinet' was. it was just like an above ground cabinet but lower. When the exchange went FTTC I went from 2.4Mb to 2 on a good day and discovered my cabinet was now at the exchange! The village where the exchange was everyone was on 17Mb anyway and I believe only one person 'upgraded' to 70Mb. The council worked with BT/Open Retch and we were promised wireless connections of 30Mb but for some reason the hardware (the fibre I'd seen going in the road) did not exist. Locally we've all gone 4G EE over the last 6 months or so. Today I was walking the dog down a country lane not far from where the fibre I saw going in to discover a new shiny green cabinet sitting on a concrete plinth! Someone I dont know on the council says they've paid a lot of money for this - despite the fact all the locals have got 18 month contracts and are probably not going to be able to convert over - though even if they did want to they'd probably move to the suppler who couldnt supply cos the fibre this cabinet is now connected to 'wasn't really there'.
Any one who has a use-case is going to get someone else to do it anyway. If you want to exercise do it and listen to your body. I used to run a lot and then fucking music players came out and people would listen to inspiring music and knacker themselves by the first corner or slow down when a lower tempo track came on and I'd plow into them. Then came those things people put on their cycle handles and they'd veer all over the fucking road trying to set them. And then came the fucking twat-fits who flex their wrists more than the average mouse wielding school boy and three of them on a freindly jog can spend ten minutes blocking the pavement trying to set/read their devices.
The only acceptable use-case for a fit-bit is for drawing dick picks on your local streets.
I've got PV banging out 3.8KW as we speak. And the immersion is on and when that starts to boil I've got a bucket of blackberries to turn into jam.
Now when a smart meter can advise my home control system there is nice cheap electricity to turn the immersion and storage heaters on (the conservatory is kicking around 30kw into the house at the mo so we wont need those tonite) then I might consider having one.
I used to use a four button puck on tablet for chip layout and the system allowed you to do gestures with various buttons which you could tie to commands - e.g. writing a Z with the blue button would zoom in to the extent of the Z area on the screen and writing it backwards would zoom out etc etc. It was a fantastically powerful thing to use and I found the two button mouse really restrictive to start with. By the time Petzold came out I'd got used to it but recently I wrote some javascript to do the same sort of thing and its incredibly powerful.
No mention of the elastic band card shuffling process when the deck got past a certain size and any attempt to put the band round it resulted in the stack flinging itself into dark corners of the room, with at least one irretrievably down the back of a radiator or mysteriously getting into the card thin gap between two filing cabinets?
No - the event horizon is the place where gravity is so strong time stops.
Before Finklestein black holes were often referred to as Frozen Stars because of this. Finklestein solved Einstein's equations from inside the event horizon and for some reason this was interpreted as allowing black holes to exist. But anything that approaches the event horizon will never be seen to cross it to an outside observer.
In the early 90s you could generate H2 from water with and get 80% of the energy required to do that in a power cell. H2 is easy to store. And if ness could be compressed and used in fuel cells in cars.
And I dare say you could use the O2 produced as well to increase the thermal efficiency of Combined Cycle systems to near 90% so saving massive amounts of gas too.
And as for another form of storage - imagine heating your hot water and storage heaters on the almost free electricity generated when the sun is shining.
If its infeasibly expensive then so is Nuclear. For the same money as a nuke you can install 60GW of solar - near twice the counties needs. It would generate more than the nuke would in their respective lifetimes, Once you have that kind of spare peak load going for effectively free then someone is going to work out how to store it one way or another so its available all the time.
As for fast charging cars its always worth remembering the London Tram Company could change a battery in a couple of minutes in 1910 or something. No reason why cars cant be designed to quickly swap out batteries - apart from people who think that people actually think their car says anything about them.
