Even if it is verified it's not groundbreaking. X-Ray litho has been done in labs since at least the 90s.

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.
Traditional dynamos are fairly small parasitic loads and not really comparable.
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.
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.
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.
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.
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.
Losses are higher but you store more energy per L, which is often the limiting factor.
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.
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.
Ideally you have a brick/stone home with good exterior insulation.
There was an experimental community in Alberta, Canada doing this. Seems to be relatively successful as pilot project.
Obviously works better the better insulated a house is. Has the advantage of turning everything in your home into a thermal battery with the only real cost being furnace controller, potentially even just software. At one point I meant to do the math to figure out the rough storage/efficiency for an average home but never got around to it.

IIRC it is calculating a few points at high precision and then estimating the rest.
Seems like being able to pin the generator at optimal revs should make up for the inefficiency of the electrical losses? But not sure.
Not renew the contract - sure. But canceling an already scheduled event because of low revenue per guest doesn't seem very likely to me?
Or maybe it was some sort of ongoing agreement and canceling it was effectively "not renewing".
Maybe if you are doing more serious stuff like business or real estate it makes sense.
Seems like something you could have paid 500-1000k (20-40USD) and been done with.
