Range extender motors should have been easy to rent and much cheaper for long trips than a full car rental.
It would be very interesting to me to have a small sedan BEV with a rear charging port and an optional flat trailer with a large battery and room for luggage/furniture. The battery would be plugged into that car while driving. I'd want the trailer rentable from the dealer for occasional long trips. BEVs seem to have powerful motors, there must be something else with the economics why this isn't a thing.
Everyone wants to rent that trailer at the same time. That is Christmas break, spring break, and summer vacations. Most of the year it is going to sit unused and so you're going to have to buy your own trailer if you want one not rented because they're just not the economics of it. You'll be paying for it either way because you're going to be the only user.
RVs are where I would think this would make the most sense. People with a travel trailer already have a heavy trailer and they want a lot of battery to get it anyway. beef up the axle a little you can put a thousand pounds of battery on you get more range when you're towing and if there's any left over your RV can run on battery power. It's also very common for them to plug in once they get where they're going and so they can charge on 220 volt power that's already at the RV park and be charged and charge your car while you're at it overnight.
I can agree: my parents bought a top loader and dryer in 1975 ('Made in Newton Iowa") which was used a few times a week for 30 years and now once a week for the last 21, as far as I know without repair. Now held by a family member they still look like the day they were delivered due to the porcelain enamel used instead of the painted metal that disintegrated on my second front loader. I've managed to repair my 3 front loaders through an average of about 8yrs each, so far.
I've joked with my wife that if I see that washer by the side of the road I'll carry it home on my back.
The reduction in cable weight probably was a big part of the savings, next to the vfd. Normally counterweights hang from the same sheave as the elevator. Its not clear to me from the sketch, but with the counterweight in different shaft the cable may have run three times the height of the building (the excessive length was noted) and that's a lot of mass to accelerate and brake.
I don't know how this possibly worked for the northern mockingbird. One full moon I stood and listened to one call continuously for an hour and I couldn't remember hearing the same call twice. Every bird I'd ever heard in person and more mimicked...several car alarms..sirens... Do they even have their own distinctive call?
Despite four years of close observation and support of the war on Ukraine the message from the Iran conflict is that the US has not learned a thing about how to efficiently fight a war against drones.
Would this be able to boost Hubble or replace it's gyros? Does the satellite servicer need its targets to be constructed to some common standards, or is the new capability now leading to common standards? Was it built with a method for itself accepting refueling?
It seems to me this device would lead to a revision in satellite reliability design and life calculations.
It's very likely that a spacecraft similar to MRV/RSGS could do a life extension mission on Hubble. But, unfortunately, Hubble is in a very different orbit than MRV/RSGS is, so we wouldn't be able to reach it.
"Does the satellite servicer need its targets to be constructed to some common standards, or is the new capability now leading to common standards?"
We can do life extension missions on client spacecraft that were not designed to be robotically compatible. That's actually SpaceLogistic's primary business case.
The question of standards in the spacecraft industry is a huge question. It's being worked... by a lot of people, cue the obligatory XKCD reference.
"Was it built with a method for itself accepting refueling?"
We are, in fact, refuelable.
"It seems to me this device would lead to a revision in satellite reliability design and life calculations."
We hope so! Spacecraft are expensive in large part because they have to be designed to be incredibly reliable. The example I use is cars. If you had to design a car that could go for half a million miles without ever having a part replaced, you could. It would just cost a billion dollars. But that's how we design spacecraft today. IF we can create a "mechanic safety net", we might be able to bring the cost down significantly.
And Casa Loma is only a castle in the same sense as the one at Disneyworld. These may be textually and superficially similar to historic castles but are completely different. A knowledgable historian would not curate this list. The author should indicate this is just a technical demonstration.
Anecdote: waiting for my childs parent-teacher interview in the library of a mid-range highschool in a large city, I casually asked the row of student facilitators how much they used the (pretty substantial) library. They all said, with emphasis, that they'd never used the library once, not even for a single book. Overhearing this a teacher looked at me and shook his head with resignation.
Is libby very popular among young school children? Based on surveys asking how often kids read per week I would figure ebook reading is also down. They don't usually ask about the format.
