Continuous monitoring isn't an issue with EVs. When you have a 24,000Wh or larger battery remaining connected to a cellular network for weeks is no issue. Remember when your Nokia could run for a week on one charge? That's what the modem in the car is like, only it has a giant car sized battery to power it.
No matter how inefficient it is, as long as it's going to produce significant amounts of energy over its lifetime and doesn't pollute then it's worth doing. 20 year payback is fine, as long as the energy is clean.
Really? Wow, good job we had you to warn us that all those marine engineers who designed the thing are idiots. After all, you came to your conclusion from just a photo, so how could they possibly have missed it?!
The point of Bitcoin is to remove control from governments, and to make pseudo-anonymous transactions possible online. Sure, in real life cash is better, but if you want to transact over the internet you need something like Bitcoin.
Notice that I said pseudo-anonymous. An IP address does not identify an individual, it could be a shared connection, free public wifi, a VPN, or Tor. You need to take additional steps to become anonymous, but Bitcoin is still better than a credit card which conveys your name and billing address to the merchant, and informs the government for taxation/oppression purposes.
We want to know what happened so that we can prevent it happening again.
Everyone in the UK should be using a VPN as standard anyway now. Between site blockades and illegal spying they are a necessary part of connecting to the internet here. Look at it this way, if you went to China you would want to use one, right? Well the UK is at least as bad as China.
Human flight is one of those ideas which seem really obvious from a distance, so the fact that project after project fails does not seem to dissuade anyone. They were obviously just doing it wrong.
With most new tech the R&D happens in a lab out of public view. The numerous failures are hidden from view and you just see the final, working prototype or a finished product. Unfortunately that isn't possible for large projects like this, so they have to do their R&D in public.
You need a reasonable upload speed, but bandwidth is infinite over time and I have backed up terabytes over a few months with a 10Mb connection.
Consumers have mostly moved to external hard drives or cloud storage. I know everyone on Slashdot hates the cloud, but as a backup medium it isn't bad. Off-site, managed by someone else and low cost due to being shared by many other users. You can encrypt everything for privacy and use multiple providers if you don't trust any single one. Might as well make use of that upstream bandwidth you paid for over night.
Most importantly it's easy. No need to remember to do it, no need to rotate disks off site or plug them back in again. Most people seem to fail at backing up because they are lazy.
I just use a laser to etch my backups into the surface of the moon, and a telescope to read them back. Occasionally I get bit rot when a meteorite hits it or a Chinese rover makes tracks over it, but that's what parity is for.
I have CDs I burned in 1996 that are still in good condition and readable on any modern optical drive. Obviously, these are Taiyo Yuden archival grade discs, not cheap rubbish, but not terribly expensive either. You really can't beat optical media for backwards compatibility - a modern BluRay drive can still read the first CDs ever pressed without any problem.
These days my preferred format is archival BluRay. Tapes need expensive drives that wear out or can mangle the tape, and while Unix backup software will be available forever that does mean you need a Linux machine to do the actual reading and writing to tape. It's a shame they didn't decide on a standard, universal filesystem for tape decades ago, like they did with CDs.
In fact the current snooping laws have already been massively abused, when the government swore that they wouldn't be because of "checks and balances". Police used RIPA to get journalist's phone records, to find out who their sources in the Plebgate scandal were. Not even investigating a crime, just protecting their own image and trying to keep themselves out of jail (the police tried to smear a politician with lies, and then lied to investigators about it, and then lied to the press about it, and were then found out).
Cameron is a coward. He said it himself - he doesn't want to be remembered as the PM on who's watch there was a terrorist incident and hadn't given in to every demand for new powers from the security services. His vanity is apparently more important to him than abstract concepts like privacy and freedom.
You could compete with the power company yourself. Install solar or maybe a wind turbine if there is room, large battery pack for backup. Will pay for itself in 10 years anyway and no more outages.
