This electrical cable can function as a tether. Maybe a steel cored, twisted aluminium strands cable (as used in medium and voltage transmission) would offer both low electric resistance, high strength, high reliability, ...
(P.S. I have small lengths of that kind of cable at home. It's probably overkill for a 10-houses sized balloon, but it can be built in smaller gauges)

This can reduce waiting times in "taxi rush hour" - would you prefer to wait 15 minutes for "your own" taxi, or share one that comes in 5 minute?
Also, if the cab carries two different passengers, cab drivers get payment from each.
      In Athens, Greece, the cabs that carry one passenger might stop and take another one that goes in the same direction (and get full payment from one passenger and partial or full payment from the other). It helps a lot with the "I can't find a cab at this time" problem.

There was a time (Prescott Pentium 4, or maybe all the Pentium 4 processors) when the ALU was "double pumped" - it worked at twice the frequency of the rest of the system. So, it was on "half a general CPU cycle" or a "full cycle of the ALU).
      But that was quite a long time ago, and more than 3 microprocessor generations had passed.

This is for Li-Ion or similar batteries used in hybrids (and maybe full-electric cars), not for the lead-acid (which usually are discarded when they have very little usable charge)

Why do the government imprisons pickpockets?
      They hate competition

A supertanker has a deck about 300 by 30 meters, so 10,000 square meters. With an optimistic 100W from square meter, and 8 hours a day of full power, you'd get about 8 MWh (or some of 28,800 MJ) of energy a day. At 43 MJ/kg for diesel fuel, that's the equivalent to some 700 kg of diesel fuel a day.
      Now, ships use heavy fuel oil when outside territorial waters (which is much cheaper), so a full deck of solar panels wouldn't save you very much money. And those panels would be exposed to salt water, storms and so on.
      I haven't found the "common" power generation for ultra large crude carriers (oil tankers), but max power seems to be over 80MW - assuming they're going at a quarter of maximum power, the solar cells would give you at most 1/60 of the needed power per day.

Even now, some people can temporarily (or completely) lose their right to vote or be elected (medical reasons or for - by example - corruption while being a member of Parliament).

I drive an Opel Astra (two doors) with a 54 liters fuel tank. I used to drive a '92 Passat (reviewed as a compact on US sites) which had a 70l fuel tank.

Not to mention parking spaces, which usually are at a premium in cities

Public transit systems are (usually) heavily subsidized. I remember the city of Tallinn (I think) introduced free public transportation, as the city did pay 75% of the real cost of the tickets anyway.

Home internet at 50 Mbps means 50 Mbps downlink and almost certainly less than 10 Mbps uplink (probably less than 5 Mbps) - and uplink is what matters in this case.

If the roads are sanded, winter tires will grip sand grains in the small creases/cuts, and this will help even on ice. Lacking sand, only chains (in they break the ice under them) and studded tires help.

M+S stands for "Mud and Snow". As such, in my country (Romania) only tires with M+S, MS, M.S. rating are legally accepted as winter tires
