Your original post says 70% loss, i.e. 30% efficiency. In the context of an e-bike, to me, 70% efficiency is fine. It's a large bike and the majority of the power for the majority of users is likely going to be coming from the battery anyways.
Also presumably we should be comparing the efficiency to other ebikes not traditional bikes. I'm not sure how effective traditional ebikes are at integrating motor + human power together but I'd imagine there are some additional losses.
Mine goes somewhat unused because of this (although definitely less than 10 swipes per try). If I was to buy another ereader I'd want at a minimum physical buttons for forward/back.
Consider a fully loaded cost of 200k for an engineer or $16,666 per month. They only have to be >1.012x engineer for the "AI" to be worth it. Of course that $200 dollars per month is probably VC subsidized right now but there is lots of money on the table for <2x improvement.
That is a tenancy in common 2 bedroom apartment not a house. Shared ownership of a 100+ year old building with "leased" parking 2 blocks away. Not exactly the home ownership dream.
There's a bajillion of them around if you search "neck cooler" or similar. Very simple product sticking a few commodity items together. Some do only have fans though.
When I looked a while ago there wasn't really a clear winner or high quality unit. There is the "Coolify" series that are much more expensive but still somewhat middling reviews overall.
Depends on the manufacturer how many unique bittings would be made. I believe ~1000 was common. So pretty low chance but high enough a few people have stories here or there.
What caused people to stop using the free service that is MySpace? What caused people stop using the free service that is Digg? Being free isn't particularly novel. Facebook isn't providing this service out of some sense of altruism. It is incredibly profitable.
What about the tariffs would cause people to stop using it? Because they - along with many other of the administrations postulations and policies - are incredibly unpopular and a complete 180 of US foreign trade policy. Because tech is a money printing machine for the US and tech oligarchs who have largely bent the knee to Trump.
Countries can and have under the name of "digital services tax". Generally the rates are low and often only cover a subset of things. The US and tech giants have historically pushed back hard on them. This is a reasonably up to date link to the situation in Europe https://taxfoundation.org/data/all/eu/digital-tax-europe-202... Keep in mind many of those are proposed and not implemented.
The real threat to the US IMO is losing marketshare. The stock market has gotten beat up but most of the real pain for the average person is still off in the horizon. Anti-US sentiment is growing quickly, if we enter a full blown global recession/depression I think it could be a real catalyst for large sudden shifts away from US tech companies.
Almost all the trade deficit numbers being thrown around by the US administration don't include trade in services which the US generally has a large surplus. A lot of that is very high margin tech SASS/advertising.
If this continues it seems like this could be a "digg->reddit" type moment for US tech. In some ways it is easier for a lot of people to leave facebook than it is for a single person. If you look at gross margins there is a lot of room for competition, though network effects make that competition very difficult. Maybe this is the catalyst for competitors to break in.
FWIW you can get thermostatic mixing valves that limits the maximum temperature of the water by mixing in cold water. Lets you run the tank hotter but have the same outlet temp. Fairly cheap I believe.
If your concern is storage you want as hot as possible, less boiling. Thermostatic mixing valves can bring the temp down to a safe temperature for use.
Losses are higher but you store more energy per L, which is often the limiting factor.
Well there are another 7.6 billion people on this planet many of whom are already feeling the consequences of the "trolling actions of a few politicians".
I'm not American or a "leftist" for reference. I have no ill will towards the American people, neither the Chinese or any other. Governments on the other hand.... But regardless if I can buy a car for 1/2 the cost from one belligerent major power over another. Yeah - I'll take the half price car.
Instead lets have them made in a place that has threatened to take over ~4 sovereign nations in the past three weeks? Yeah I'll take the 1/2 price cars thanks.
I love this. I fly a decent amount in Canada/USA on economy and almost every single time there is a massive line of gate humpers who haven't been called to board and are trying to get their oversized luggage into the overhead bins.
My greatest hope for airlines is someone starts a company focused on banning people. Bag too big for carry on? Banned. Wearing too much perfume? Banned. Got in line before your group was called. Guess what. Yeah. Banned.
