I’d rather not wear anything on my wrists but I like data so wear an Apple watch 7 to collect health data. I use Health Auto Export app on iOS to sync health data to homeassistant. I found straightforward guide to set it up but it is not perfect, need to open the app regularly for the data sync to happen. Battery life sucks, for my usage max it’ll last is a little over 2 days. Quick charging works well enough so usually only gotta charge for a few mins once a day.
Add some good (low sugar and low added fats) peanut butter or any other nut butter and/or ground nuts to your oats. Makes for a healthy and calorie rich meal that keeps you sated for a while. It’s easy on the stomach, does not cause the blood sugar to rise quickly and you can eat it spoon by spoon over the whole day, if necessary.
Also don’t forget to drink plenty. I find tea and highly diluted apple juice (like 10%) are ideal when I am sick.
I was really sick and couldn’t eat much of anything for 2 months and lived mostly on the chocolate Soylent. I had issues staying hydrated so I also drank a lot of Liquid IV (Pina colada and watermelon were my favorites).
As I started to tolerate more solid food I ate: canned soup purees like butternut squash/tomato bisque/pea soup, powdered soup mixes from Bob’s Red Mill or Knorr, steel cut oatmeal with mushrooms and chicken broth cooked in a pressure cooker, rolled oatmeal with nuts and dried fruit, grits, plain rice crackers, nut thins, fage 5% yogurt, bananas plain or blended up with milk, applesauce, cottage cheese, carrots cooked to mush. Also ate a lot of sweet potatoes and russet potatoes, I cooked a bunch of them whole in the pressure cooker at once and then I’d eat them all week.
Some of my friends recommended Huel or Plenny shakes but I never got around to ordering any.
I’d also avoid anything with too much oil, fat, hot spices, or sugar which can irritate the stomach and limit cruciferous vegetables like broccoli, cauliflower, kale which can be hard to digest.
Chicken soup, plain white rice, buttered toast, peanut butter, and crackers are all things I can usually tolerate when I feel that way. Sometimes banana or vanilla yogurt. I hope you feel better soon!
There will likely be lots of wind energy too which could alleviate the solar problem, though this is based on luck. Passed that the ideal solution is nuclear energy and in the future fission based reactors if they are economically viable.
What’s most feasible today in most places would be burning gas. I know it’s not perfect and still emits plenty of CO2 but the plants are much faster, cheaper and easier to build than nuclear, and gas burns much cleaner than coal or oil. Plus it can be stored and transported fairly efficiently by LNG container ships.
Okay any engineers up for a hypothetical? As others have pointed out, things like wind, nuclear, and other things are sensible answers. BUT WHAT ABOUT AN INSANE ANSWER?
It obviously would be prohibitive to have a colossal "city battery" that stored excess from the day to be used at night, and environmentally would present issues making a city sized battery. But what about a non-traditional kinetic battery (think F1's KERS). What if there was say a building in the middle of the city, and inside is a metal disk made of solid steel that's a foot thick, and 500 feet across, on an electromagnetic cushion, housed in a room with negative pressure or a vacuum. During the day, the excess solar energy from the city powers this to gradually spin faster and faster, and during the night this process is reversed with the enormous amount of kinetic energy feeding a powerstation generator that would provide power at night. Okay, I told you it was an insane hypothetical, but as thought experiment humour me. It would by definition be a battery, but one that wouldn't deteroriate in the same was as a chemical battery, without the same environmental impact of involving all the cobalt, lithium, etc., although it admittedly would be pretty wildly expensive just from a space, and material cost of the disk perspective. How big would this need to be? Is this remotely possible? I mean WAY less power is used at night after all. Thoughts?
I like insane hypotheticals that are discussed as hypocriticals. Not an engineer on paper, but these are my thoughts.
I think a very heavy weight that fits neatly inside of a protective structure with room to raise and lower it would be the way to get a kinetic battery. I’m talking about a platform stacked with concrete and rocks and sand and building demolition debris until it has stacked up to 2 or 3 stories tall. Then build a basic shell around it to blend into the town and have that 6 to 8 stories tall. The weight would tug at cables or press down on a hydraulic cylinder at a constant rate. A motor would then spin a large set of extreme reduction gears to raise the weight when there’s extra power coming in. Then, the tremendous weight could drive the reduction gears to spin the motor as a generator at a constant rate and make reliable power.
The less crazy version of this has been proposed, a set of cranes stacking up and lowering down more reasonably size blocks to store power inside of a tall structure.
None of this is practical. You can’t build a tower like this for any real storage, it’s just not efficient. The only effective method is running a train up a mountain, or pumping water uphill. If you have to actually build a mountain a first, it’s not going to work.
The statistic you’re looking for is energy density. It’s usually expressed as Watthour per kilo(Wh/kg). Li-ion batteries are somewhere around 300Wh/kg, or about 1 megajoule though less if you’re making it into a building.
Lifting a big weight provides you with Mass x 9.81 x Height amount of joules. So lifting 1 kg for 100m gives you 1x10x100~ 1 kilojoule.
So, to charge my 300kg, 32.000 Wh Nissan leaf battery (130Wh/kg, what you get when you actually build batteries in the real world), you would need to lift a mass of 115tons to 100 meters. So to charge a single car, at 100% efficiency, you need to lift 72 entire cars. Just so I can drive to work and back. And real-world efficiency is far below 100%, just think of the friction.
I think you’ve spotted the reason why we don’t actually build gravity batteries. Imagine lifting 115 tons to 100m, that requires a massive crane, itself weighting nearly half that. That’s why all gravity storage in existence basically consists of pumping water uphill, onto pre-existing mountains and lakes that nobody had to fabricate out of concrete and steel.
One of their main problems is that, as you pump enough energy into them to justify their cost compared to other storage mechanisms, the spinning mass becomes more and more of a danger if it ever breaks loose. Not to mention the gyroscopic effect making a “fully charged” fly wheel very hard to safely move.
Use sentence case and periods. I’ve seen other communities where omitting periods was fine. Also, try not to use emojis but if you do, do it sparingly.
Regular analogue silver/black self-winder 99% of the time.
Also, an offline smart-watch with gadgetbridge to record bike riding and badminton(heart rate, steps, GPS, duration, date, etc)
The simple smartwatch I have is older but does the job OK. Amazfit Bip. No need to pair it with a website to enable, just record sport and lift data off to gadgetbridge app.
That honestly sounds like a great balance! Plus, you have some privacy with your health data with that offline Amazfit, so some goons won’t sell that private info to some corner of the internet.
I used to have to force feed myself when I wasn’t hungry. Ramen was essential for priming the appetite. But not the bad stuff. Good stuff like Black Shin
Regular watches - been wearing watches of some kind since middle school, and at this point I feel undressed or like something is missing without anything on my wrist. Like many others here, while I love the tech of smartphones (and admittedly the smart watches are really cool) but don’t want an even more in-my-face screen to further pull me into more phone time. Trying to really cut back on screen time. Also, if I went for a smart watch, I’d feel the want to wear it all the time both because of how much they are and to keep activity tracking data consistent, which would mean my collection of watches would likely get much less wear time.
Watch I have on now is the Citizen Eco-drive I got when I graduated college, years of service and frequent wear in situations I had no business wearing it and it’s held up great. Because of the eco-drive it’s one of my few watches I don’t have to worry about, it just always has the right time.
I really do relate to your reasons. I had been using a smartwatch from spring 2020 until last week, and while it was great for some fitness tracking, it ended up giving me health anxiety due to the constant feeling of ‘needing’ to meet all my fitness goals daily, and the notifications buzzing my wrist regularly breaking my concentration during work, or for slower times of the day such as sitting on the couch with my headphones and just focusing on the music.
Citizen FTW! Their Eco Drive Watches are the real deal. Accurate, reliable, won’t break the bank. Citizen really do live up to their name as a company, they’ve created a practical and economical slew of products that appeal to the everyday working man. Plan on getting one myself soon!
