I suspect that the hover mechanism could do a fair bit of the work; but I posited additional elements because it would be a bit of a downer if the hover mechanism were tuned too far in the direction of being a good thruster/steering element, since you'd be walking a potentially touchy compromise between being capable of aggressive maneuvers and being inherently stable, rather than liable to assist you in tipping over even faster and harder that gravity would cover if you leaned too far out of the equilibrium position.

Just for the sake of consumer safety and not reducing bystanders to hamburger too often, the preferred arrangement would probably be some sort of EDF/Vectored thrust arrangement: all the advantages of a standard electric propeller (ambient-temp exhaust, none of the noise and fuel-line hassle associated with teeny internal combustion engines, runs on normal batteries rather than some sort of hobby fuel); but no exposed blades to do surprising amounts of damage upon somebody's first mistake.

You'd have to avoid going too deep into propeller-beanie-chic zones of absurdity; but if you could get the actually-hovering bit worked out, I suspect people would overlook that for the chance to zoom around at dubiously sensible speeds.

The hustling scammers, the druggies and drunks, the mentially ill, or the real homeless that are down on their luck and actually trying?

Because the first two I ignore completely. The mentially Ill I feel really bad for, and the onesthatare really down on their luck are not on the street corners hustling for money. Those people are helped by my donations to homeless shelters and to women and children shelters.

The fake hustler that is claiming they are a veteran standing there with a sign? Or the one guy I see push his wheel chair up to the corner then get in it with his hand out? they can stuff it.

It is a royal pain in the ass to get a IMEI blacklisted. I had to fight AT&T even though I sent them the police report and the phone was in their records as my property.
"But it's currently activated" Yes, by the thief, blacklist it.
"but that is one of our gophone customers", Yes the thief blacklist it.
"but but....." Do I need to get a lawyer involved?
"One moment please...."

99% will not force them to blacklist the phone but just let it go. To hell with who they sold the phone to, I was not going to stop until the phone was forever disabled from being a phone.

My (admittedly pretty hazy at this point) memory of heat engines is that their theoretical peak efficiency depends on the thermal delta they manage to achieve. Exactly the same resource that thermoelectric materials scavenge (albeit at miserable efficiency) into electricity.

Anybody who actually has some grasp of the matter want to chime in on where and why you would use thermoelectrics (and how efficient they would have to be) rather than simple insulation or one of the various waste-heat-recovery systems that transfer some amount of the heat remaing in outgoing exhaust gases into incoming working fluids?

Is the thermoelectric advantage purely that, assuming material reliability is OK, they are a 100% solid state, trivial to scale from 'handle with tweezers and magnification' to 'pretty large', and their output is easy to transfer and useful for all kinds of things after just a little DC-DC cleanup, or are there actually situations where they might be absolutely more efficient than insulation and heat recovery, rather than just easier to tack in almost anywhere in a design that you have a few extra cubic centimeters and expect a temperature difference?

Cargo
I started the long walk back to the pilot room wishing again for a bicycle or something.
A robot wheeled past. Hell, I should just flag down a robot. But, of course there was a reason for not having transportation; I remembered the climb up the boat when the whores locked me out and how tiring it was. A body needs exercise and the most I was going to get on a boat with two-thirds gravity was walking.

Most parents today are horrible. They do NOT interact with the chile like laying on the floor and playing with them. Get your asses off the couch and lie on the floor playing with your kids showing them how to stack blocks, and play.

I gave my daughter a earfull having my granddaughter use the ipad at 2 to keep her entertained. No you play with her using physical objects, and interaction.
