  • Sorry this is a late reply. I can see that mentioning molten salt was a bit left-field, However, it is one of the more realistic ways to store the huge amounts of power needed to fuel an economy for a couple of weeks (which you need in northern europe if you want to use solar/wind). Here’s a link about it:

    I am pro nuclear, but if we are going to descend into this renewable hell, then we need to actually think about how you store terawatt-hours of power. I really think that this kind of storage might be the nearest we have to a solution. we’ll only need it once we try to turn off the gas turbines, of course. It is fascinating that so many smart people don’t see that the whole jigsaw is missing vital pieces.


  • Sorry - What?

    You said Denmark had converted to green energy. I pointed out that they haven’t done anything like that. You are now moving the goal posts and saying “where is the comparative essay defending nuclear power”…

    If you must, France turned completely green in the 70s. So they’ve provided 50 years of clean energy. Its a classic story and not as simple as I’m going to make out, but still. Look at the map link in the last post - any area that stays green is either using hydro or nuclear. Hydro is great, but you need mountains and water.












  • I have thought about this from time to time. I want good surveillance, but I also don’t want to lose control of the video.

    I think that the solution that I favor right now is a Wyze cam V2 or similar flashed with openmiko. edit:(I had to buy wyze v2 cameras from the US on ebay to get v2 versions, user:@ashok36@[email protected] suggests in this comment to use v3 and Wyzemini firmware - this might do the job. clarification: the point is to replace the manufacturer’s firmware which will phone home with something open source that you could audit)

    These can be attached via USB or wifi interface to a server with zoneminder (https://zoneminder.com/) From there you could think about offsite records too and motion detection etc. [edit: wifi is useful as I don’t want to rewire the house - though could be blocked (or the router could be unplugged!) if you are expecting technically savvy criminals. A solution here would be to use an old router on a separate wifi network, put somewhere where most of the property would have been traversed before it could be accessed (e.g. upstairs).]

    Having said this, the setup is just fiddly enough that I keep to finding myself finding other stuff to do. [edit: ‘Fiddly’ is the wrong word, I think its pretty simple, I just find myself wanting more features until the project doesn’t happen at all. I’d be clear that this is a feasible DIY project, so long as you accept that ‘done’ is better than ‘perfect’]

    [edit: One last note - if you host the video yourself, you take responsibility for the security - this means keeping zoneminder and the OS up to date and offsite backups/networks/cameras secure. This is possibly something that a company is better at (but don’t bet on it!). However, you are also a smaller attack target (because bad actors only get your video) so blackmailing you with whatever you do in your surveilled place is less valuable than having the same data for 1000s of people. Also, if someone has access to your home network - they can set up man-in-the-middle attacks and steal your bank details - you have to be doing something interesting in front of those cameras for it to be worth more than the contents of your bank account.]
