I think a mobile phone camera is vastly superior to these, although might not be great at night vision for the reasons you said, but is it entirely crazy to not just use a spare phone? It has built in backup power, can store videos locally if there is an internet outage, and can use its own data connection if wifi is not available.

Actually, I am very lazy, thank you.

You can use superconductors to create Josephson junctions, which can be used for standard logic operations (but also useful in quantum computers). These junctions are much more efficient and much faster than transistors.

This particular superconductor will not be useful for transmitting power because the effect breaks down at very low current limits in this material, but it will be very useful for studying superconductors.

So contrary to what you said, this will in fact not be useful for power transmission, but could be useful for CPUs and GPUs, and could lead to computers that are hundreds or thousands of times faster and more efficient than what we have today.

To be fair this material may never see a practical use though.

One of the things that weighs me down is posts making me dwell on the things that weigh me down.

I'm located in a van in New Zealand so I only use mobile data. I pay NZ$40 (US$25) per month for "unlimited" data, which is all I can eat but capped at 1Mbps. I can stream 720p barely, but I mostly torrent. I typically use about 60-80GB a month.

I think you're right there. My bad.

They say the second layer retains 93% of the performance of the first using reflected light, making it 20% efficient, so, yes they are added in that case.

TLDR; the front side is 23% efficient, and the rear side 20% efficient.

They don't actually give an overall efficiency but it implies a total of 43%. They compare this to typical panels also at 23% efficient, so it's really remarkable if true. Other emerging solar tech is up to about 32% but if that could also benefit from multiple layers then total efficiency could become insane.

Seems a little too good to be true, really, but great if so.

Edit: Yeah, I don't think these efficiencies can be added like that. I guess the overall efficiency will depend on how reflective the ground under the panels is, and they will extract 20% of that. Maybe that's why they don't give an overall rating.

I think it's intellectually lazy to stick with the stochastic parrot line of thinking now. There's a number of emergent properties that are appearing as LLMs scale that give them abilities beyond that paradigm. Check out the "Sparks of AGI" paper from Microsoft research - or more realistically one of the youtube summaries of it since its quite a big read... Here's one from the horse's mouth: https://m.youtube.com/watch?v=qbIk7-JPB2c

Yes, I don't think people realise the scale of production involved. We're currently producing about 8500 TWh of power with renewables annually (nuclear is about 2600 TWh), and adding about 585 TWh of renewables per year (this is steadily increasing). A typical nuke plant generates about 8.5 TWh annually, so we would need to be building 68 new nukes every year to keep up with renewables (at current renewable numbers). The cost and construction time is massively prohibitive for nuclear, uranium mining is pretty dirty and there's some downsides of nuclear waste at present. Yes, there's some emerging tech but we won't be building many of those for some time to come.

It seems unlikely nukes are a practical path to any significant contribution to new generation required and they will continue to fall behind. They can help but they're not the magic bullet many people seem to think. Solar, wind and hydro will dominate in the medium term. I think they will ultimately make way for geothermal to dominate, maybe via plasma deep drilling like Quaise or PLASMABit utilise to potentially make bores up to 20 km deep, which opens much of the world up to being suitable.

Fusion may become practical in the next 20 years or so, but that will also be ludicrously expensive, so also unlikely to make a meaningful contribution in the medium term either.

Anyone who isn't at least mildly interested that you know Morse code isn't someone you want to know :-)

Good filter technique.

No. I only use Android as my PC via AR glasses. Is there even any antivirus software for Android? Probably, but I don't care I guess. Never had a problem.
