Solar Super Capacitor Cars Trucks & SUV's

Keeping li-ion batteries 100% full causes them to lose capacity faster, as does fast charging, high heat, noting many commercial li-ion chemistries in mass produced batteries are prone to fading capacity issues.

Look at Boeing 787 battery, Samsung Galaxy S7, Hoverboards, Tesla installing a titanium plate under some BEV models after it was proven that a electric car with lithium ion batteries that catches fire because the batteries have a problem, can be very difficult to extinguish with firefighting methods, and the very high DC voltages inside the burning EV also hazardous when Tesla model whatever get into an energetic highly mechanically intense road accident. 

Many improperly designed or flawed manufacturing lithium-ion batteries are liable to catch fire while charging or discharging or from short circuiting if mechanically damaged or thermal runaway fire if overheated. Super Capacitors while holding less energy, can be float charged to full & cycled for tens of thousands of cycles without damage, vastly superior in terms of durability and long life than most lithium ion batteries.

Yet lithium titanate used in Citizen solar electric wrist watches can last 20 years or 55,000 cycles, but at only 2.4v Lithium Titanate not a popular li-ion battery in other applications. Some dash cams & solar electric wrist watches, clocks, long life compact information displays, calculators, low power portable electronic devices, can make use of a 2.4v Lithium Titanate cell with superior long life power storage & cycling than lithium cobalt oxide hard carbon, the kind of lithium battery used in a smartphone or tablet or laptop or that fade prone NMC NCA stuff that Tesla loads into EV sold in America while using longer lasting superior but less energy dense LFP in Tesla models sold abroad. 

Never Use Brake Cleaner on a soon to be Welded Part, it releases toxic Phosgene gas, break cleaner residue super-heated by welding arc produces phosgene gas

PSA for DIY welding, cleaning parts with brake cleaner dangerous, residue left behind after using brake cleaner can react with hot welding arc to release extremely deadly phosphene gas! 

US National Parks so Busy during Peak Hours, new Gate Control System Requires Online Reservations Weeks or Months Ahead

Tragedy of the commons, when tons of people all descend on a public place, the aftermath usually wrecked with garbage, spilled food and beverage, overflowing trash cans, plastic waste blowing around in the wind, and in a wild natural setting this kind of human impact becomes multiplied when there are too many people in the same place. 

China has this problem in many cities in China because they have the world's largest population. Many larger cities in China have a population of 90 million people, so many new car buyers in fact, road could never handle that many personal vehicles, so they setup a lottery system, where a person has to apply months or years ahead to get a parking space, vehicle registration, & pass to buy a vehicle, car, truck or SUV, noting how many peak traffic situations in China create stop & go congestion lasting for 3+ hours, people stuck in their car for 4, 5, 6, or 7 hour. I would piss myself if stuck for that long, especially after drinking coffee or tea, which are very popular in China. 

Road trips across rural America where you can access National Parks was historically a spontaneous thing, where you would pack up your vehicle with food, water, gear & leave as a family for a long road trip across America, some in RV pulled by a truck, others in Motorhomes, but many people take a family of 4 in a mid sized SUV, other like my wife & I are able to drive a sub-compact Corolla Sedan or Prius, sits its just the two of us, and all the other utility space sufficient for all our fear & luggage & supplies. 

We have gone on many road trips across America but frequently encounter overcrowding with our unlimited 1-year national park pass. We were even force to pay extra with the unlimited pass, for parking & for each person to access, in one case they forced us to use our smartphones to setup an online registration, but no signal in the entry area, meant we had to do U turn & drive up to the top of a ridge where our phones had 4G or 5G access, probably LTE-adv, & we were able to setup a time specific reservation in rural Moab Utah, and the hiking inside after parking, ended up being really fantastic. We met and spoke with many polite, kind, outgoing travelers like us. 

It was spectacular and worth the extra effort. That being said, having to register online when already at the gate, pay extra when we already purchased the most expensive unlimited annual pass, it made it a premium access experience at higher cost, underscoring how that makes it unfair to lower income families who's only practical vacation access is a road trip in the daily use commuter vehicle, across America, often to visit amazing National Parks. 

Even as a child I wondered, why do people in large groups wreck areas the visit? Are there too many drunk people or people high on drugs? Why anyone thinks its ok to litter & throw trash on the ground befuddles me. I consider people who litter low quality low brow low functioning inconsiderate selfish self absorbed rude people.

Many youtubers have channels called Instant Payback or Instant Karma, usually people in SUV throwing fast food containers out their window, then a do-good-er on a motorcycle with a helmet cam picks up the trash, taps on the window of the littering car, then when they open the window, throws the trash back into the vehicle that littered, forcing the littering person to realize that what they did was socially emotionally & environmentally inconsiderate, littering in most place around the world is also illegal & people who are caught littering are subject to fines, they have to pay the police a fee for littering, if the police catch them littering, often in traffic. 

In Oregon, on a road trip, my wife I spotted a No Littering sign, $6250 fine for littering, wow, we were astonished at the high fee for littering and have talked about how amazing it is that the state of Oregon had to raise the fine that high to get people to stop littering. I wonder why they are so many people willing to throw trash out of their car, truck or SUV? What is wrong with these people? Are they dumb as a box of rocks? Or just so self-absorbed they feel entitled to treat Earth as a personal trash dump.

 

Coffee, Caffeine, Tapering Back, More Sleep, Recovery, Health, Upper Limits & More

WHO, NIH, FDA recommending a maximum daily intake of 400mg Caffeine

What does 400mg of caffeine mean in terms of coffee, tea, cola / soda or energy drinks? A typical cup of tea, single shot of espresso, 8oz energy drink or 12 oz soda have 70-90mg caffeine

With coffee, your grinds to water ratio, hot water infusion temperature, time for extraction, pressure of extraction, method of making coffee, will all influence aroma, taste, flavor & caffeine content.

Using James Hoffman method, 30grams of coffee beans freshly ground, 185F hot water, into a French Press, SS, Glass or Ceramic, 5 min brew time, press basket, rotate cap, dispense hot coffee. Notice amount of water missing, how many ml or grams of water? 

30g coffee about 450mg caffeine
1 gram of ground coffee contains about 15mg of caffeine
3 grams of tea leaves contains about 20mg of caffeine

In my personal SS French Press, double wall insulated camping approved model, 18oz of water along with 30 grams of hand grinder coffee grinds fills the unit enough so that the cap & basket pressed into it do not cause coffee to spill out of the spout, but just barely. This is strong coffee, resulting 17.75oz of coffee you dispense contains over 400mg of caffeine.

I was doing this daily for almost 18 months, when I decided to do back to doing a double shot of espresso into room temp water to dial back, that would be 24 grams with 12 grams in each shot. Then after a few times of doing 2 shots in water, I went to one 12 gram shot in 12 oz of water, now on day 2 of this. I am slowly dialing back caffeine intake, similar to intermittent fasting to dial back calories. 

Why would an adult want to dial back caffeine, to reduce tolerance, improve gastric stability, increase hydration & sleep quality, & feel more rested, less jittery, less anxious, less disturbed, less annoyed, to become calmer & more stable, to feel tranquility and peace without over stimulation. So that you do not have to wake up in the middle of the night to pee as much. To lower your blood pressure. To not upset your tummy as much. Tapering off slowly over the course of 2 weeks also helps to avoid headache, nausea, irritation, & other side effects of abrupt cold turkey stopping all sources of caffeine. I did the same think to stop drinking alcohol, I gradually dialed back until giving it up entirely.  

Dr Sten Ekberg on YouTube says "Caffeine lets you borrow more energy now, but you end up having to pay it back later" "like spending on a credit card, then having to stress about the balance increasing" "you borrow now but have to pay it back later" analogy. I was inspired to cut back on coffee intake after watching his video about Caffeine. 

Adenosine builds up during your time awake, eventually plugging into all its receptors to cause you to become tired & seek sleep and to go to bed & fall asleep & continue sleeping for at least 5 cycles, that five deep cycles in 6 hours or as much as 9 hours if your cycles are longer, some people can get away with 4 cycles inside of 5 hours of sleep, other people can sleep for 12 hours & get 8 cycles because they have sleep debt from not sleeping enough previously or having a sleep disorder or crazy variable work schedules, close then open earlier, or late night then early morning, so many people in USA are sleep deprived that it actually increases vehicle accident rates. 

Caffeine block Adenosine receptors, so as to prevent accumulated while awake increasing drowsiness, and caffeine a wakefulness promoting agent, performance enhancing drug, but not a stimulant. It is true that coffee contains many other substances, more than 10,000 that upregulated dopamine release, improve dopamine transport, improve dopamine receptor binding, reduce dopamine metabolism to keep it bound to its receptor longer, and does the same for norepinephrine and serotonin, just weakly so, nothing as extreme as mixed salts of amphetamine like Adderall or methamphetamine. 

Coffee is a weak microdosing cocktail of antidepressant wakefulness promoting early AM pick-me-up, but going above 400mg of caffeine can increase risks of sleep disorders, gastric problems, increased urination at night, dehydration, high blood pressure & many other problems. 

In terms of caffeine, like food in older age, less can be much more, as in healthier, better for your wellness and overall health. Over-eating increases risks of all causes of mortality but so does abusing caffeine in excess. Same can be said for sugar or cocaine, using less, less of the time, less often, at lower doses, ends up being better overall that abusing at increasing doses.

Noting that if Fentanyl users measured out 20mcg, that would be a relatively safe hit, but many are taking 200mg, a fatal dose, because they are not having a high precision scale needed for microgram measurements and are not familiar with how to operate a scientific scale. I believe social workers & government should be educating public about dosing, how to measure a safe dose, noting that 120,000 young people have died in USA from fatal fentanyl overdose. 

Day 6 of 1 shot espresso in water diluted, still going strong, much more sensitive now, maintaining for 8 more days, may continue to do one 12 gram shot per day for a long time for other reasons!
