No. It lasts years because pacemakers have a really tiny power draw.
There's not a miniature nuclear reactor in there, it's just a RTG, which is simple but also very inefficient. So it doesn't get the crazy amount of power from a tiny amount of material a fission reactor does.
> There's not a miniature nuclear reactor in there, it's just a RTG,
I believe these are not RTGs (radioisotope thermoelectric generators.) Rather they use radiovoltaic conversion, probably alphavoltaic conversion judging by the use of Pu-238. Such devices convert alpha or beta radiation directly to electricity using semiconductors, not unlike photovoltaic cells.
But your point still holds, these atomic batteries produce a tiny amount of power.
It would take about 50,000 hours (5.7 years) to charge a 10 Wh iPhone. A solar cell on the back of the iphone would take roughly a full sunny day to charge an iPhone, with ~2 watts peak output.
> Even weak indoor light would eventually charge it.
No, it wouldn't. Sunlight is ~1 kW per m^2. A medium-sized room has maybe a couple 60 watt bulbs, spread over 10+ m^2, each of which radiates ~10 watts of actual light.
Light indoors is pretty easily 1000x less than outdoors. Eyes work exceptionally well in low light conditions, so we don't even realize the enormous difference in brightness.
Current 60W bulbs are about 10W, probably giving off 3W of light.
If it's on for 8hrs a day and you capture all of it, on 1/5000th of a room, you get... 4mWh, or in reality, 0.7mWh because panels aren't perfect?
You could make a call in a few months of charge time. with a 3x3inch panel. But yeah, I suppose I was wrong and "eventually" is a bit of an understatement.
For actual power, no it would be wildly impractical. However there is a concept of a nuclear top-off battery which keeps your main chemical battery from draining during long periods when not it use. So you could throw a charged phone in a drawer and come back months or years later and it's still good to go. Good for applications like an emergency kit.
I have this too. Someone had a good list of things to be doing to optimize your environment. They definitely help. I would add:
1. putting on pyjamas at a certain time every day (e.g. 9:30 pm).
2. not eating anything after 8-9 pm, only drinking water.
3. have other activities like reading to do in the 1-2 hours before bed.
4. no stimulants in the afternoon. No chocolate in the evening. (easy to ignore but makes a big difference).
The biggest psychological bad-habit I had to get over was ignoring my body/mind when I felt tired. If that means falling asleep in weird places, slightly earlier than expected or when there was still something I felt I needed to do, then just accept defeat for that day and let sleep take you over. Allowing my ego to accept defeat at the end of every day, to let sleep be the victor, that is the best way I can frame it for myself. In the end we're creatures that need sleep and to deny my own biology in that regard will lead to my own undoing.
The Liberty was also very far from where the Americans had told the Israelis where it would be. Finding the ship there was unexpected and calls to confirm its identity were not being answered.
It's not a land dispute. The USA has been making the claim that as an arctic nation it has an at will right to use the Northwest Passage through Canada's most northern shore and the archipelago. This shipping route is MUCH cheaper in fuel compared to using the Panama Canal, which is not obvious on a map because the world is round. Now let's say the canal has a million dollar toll, well Canada sure wouldn't mind having our own toll since keeping that channel clear isn't free. But that just ignores the whole natsec/sovereignty issue of are we just ok with having people pass in and out as they please and how will international courts treat it if we allow that but later wish to change our minds.
The issue comes down to whether the passage is qualified as territorial waters or just exclusive economic zones and how the islands are connected to the mainland may determine that. Regardless, the US is pushing it because it's a useful way to get concessions on other issues. Like him or hate him, understanding and using that aspect of negotiation is one thing Trump was always very good at and in this case Mike Pompeo was the one putting it forward and lobbying other countries to see it their way.
Purchasing the F35s has been discussed here since at least 2007 when Russia was flying bombers into Canadian northern territories. Something is needed to respond assert sovereignty over the area. A potential issue in theory of purchasing the F35s is a strategic one of maintaining those water rights if in the moment Russia starts moving in suddenly the planes don't work or need parts and the US suddenly has a great point leverage.
It's not quite that. The US isn't claiming that they should have access to the Northwest Passage as an arctic nation, but rather that there should be international right of passage through the Northwest Territory, ie, between Canadian landmasses.
There is militarily 0 need to use an F-35 to intercept Russian bombers. Actually the F-35 is pretty bad at interceptions. The F-35 has a pitiful 1100km combat radius, and cannot supercruise. The Gripen is a bit better and may be able to supercruise meaning that it's effective interception range is significantly better, and most importantly can usefully utilise drop-tanks. Even the CF-18 is a better interceptor than the F-35.
The F-35 is not the right choice to deter Russia in the arctic. It's the right choice if you're planning an invasion or need to do strike missions past enemy air defences, or if you're going to be doing air-to-air combat far from home.
Not just on TikTok, I saw it on YouTube clips from outside the USA. I've know people who've worked on such bases and have heard how strict they were with orders to stop and look away or at the ground when an alarm went off. Well I was pretty surprised to see it and like others, the thought crossed my mind that it wasn't an accident. Furthermore, it looked familiar...I think I saw another diagram picture about a year ago, possibly on a military-tech YouTube channel, possibly by an eastern-european creator. There was discussion at the same time that the next generation was not just approved but already created.
The sheer amount of bugs planted in buildings, especially at time of construction, has been an astonishing revelation to me. It’s funny to think that this is a full time job but many people have no idea it happens.
lol by that logic we should be careful in how we trade because we wouldn't want to make "the market" fearful. Also, that link interesting because I've only ever followed the VIX and didn't know about the others in that list.
Honestly, that's what I assumed they did in MacOS 11.5.2 where they refused to give details of the change. It's likely the last update for many intel devices.
