Make any payments to the extortionists illegal and hold executives personally responsible if their company or contractors do so. Remove the profit motive.

More and more laptop keyboards are getting heat-staked to the palmrest. I ditched an otherwise usable MSI laptop because it was too hard to source/expensive to replace the keyboard. I replaced it with a dell that was also heatstaked, but at least the parts were available.

4K cycles is about 11 years, cycled every day. I've seen estimates of 20+ years to 80% capacity if you don't need the full 80% DoD. They haven't been in wide use long enough to confirm it yet, unlike the NiFE.

If you're running off shore power most of the time or not full cycling it every day, I can see it. Prices might be different when you next need to replace the bank.

Marine AGM's are generally good for ~300-700 cycles at 80% DoD (depends on deep cycle vs starting etc, but most marine batteries are hybrid). I think their main advantage for a boat is they don't have a BMS and can put out enough current to double as starting batteries, no? Also, LiFePO4 should not be charged below 0C.

Rough AGM equivalent to the lithium cells... 4x Mastervolt 8D AGM 270 Ah batteries, $4k from West Marine. Datasheet doesn't give cycles, but website says around 500. Does give you 1200 CCA. These are also packaged batteries.. the setup I described earlier is a bunch of cells you have to secure and install bus bars and BMS, like the NiFE cells.

I think the NiFE payoff would be a long time down the road, at their current prices and low charge efficiency, but I haven't run the numbers... depends a lot on specific requirements and prices.

NiFE seems to be running at least 4x the price of Lifepo4 cells. $12765 + shipping for 300 Ah 48V pack from Iron Edison. $2000-3000 delivered for 280 Ah Lifepo4 (Lishen or Eve) 16x (48v) rated for 4k cycles @ 80% DoD. NiFE is 80% efficient in charge storage, Lifepo4 runs 95-99%.

Not really true... the satellites are on low orbits that precess across the surface of the earth. The same satellites that serve land serve the sea. The extra satellites are for higher latitudes... 55 degree inclination vs polar orbits.

What really enables the open water service are intersatellite links and to a lesser degree extra ground stations.

They saw, as others have previously shown, that blocking fermentation slows down cancer cellsâ(TM) growth. [..]

When the researchers treated the cells with a drug that stimulates NAD+ production, they found that the cells started rapidly proliferating again, even though they still couldnâ(TM)t perform fermentation. This led the researchers to theorize that when cells are growing rapidly, they need NAD+ more than they need ATP.[..]

The findings suggest that drugs that force cancer cells to switch back to aerobic respiration instead of fermentation could offer a possible way to treat tumors. Drugs that inhibit NAD+ production could also have a beneficial effect, the researchers say.

The Most Powerful Rocket Ever Flown was the Saturn V (N1 was bigger but didn't fly successfully). SLS has not flown yet, and may be beaten to first launch by the much larger Superheavy/Starship at the rate things are slipping.

I think you're mixing up Remdesivir with dexamethasone, which is a cheap generic and also shows promise in treating COVID-19.

Why do you assume 15ms is a single hop? One way speed of light delay to 550 kilometers is ~2 ms. Satellite will likely not be directly overhead which will add to that, but a 15 ms single-bounce latency seems possible.

SpaceX has actual data, as the two test satellites have been in roughly that orbit. Worst-case latency will be higher.

For reference, one way speed of light delay to geostationary is at least 120 ms.

SpaceX's revised FCC filing calls for about 1.6k of the initial 4.4k constellation to be at 550km orbit. Brings the minimum latency down to 15ms, instead of 25-35ms.

If the book is good, why would they wait 20 years to publish it, and forego profits from the next 20 books? It takes time and money to generate interest in an author; one hit wonders are fairly rare.

I've seen a horse eat an entire McDonald's combo meal. She did had trouble with the soda and spilled most of it.

(She was also the one who loved twislers, and if she found them would eat them wrapper and all.)
