I'm pretty sure Tesla assumed liability when they had a car deliver itself to a customer in Austin this year.[1] Also Tesla is an insurance provider in many states, and where it's legal to do so (Arizona & Texas currently), th

That balloon has a payload of up to 55lbs, so it follows different rules. WindBorne balloons are 1.1kg including the initial ballast. There are ADS-B transmitters that weigh 50 grams and would require 60 grams of batteries to power them for

I am using the Econ 101 definition.[1] Examples of public goods include lighthouses, knowledge, a common language, and national defense. The reason for the different classification is because public goods obey different economic laws. For e

Bridges are not public goods. Public goods are non-excludable and non-rivalrous. Bridges are both excludable (people can be prevented from crossing unless they pay a toll) and rivalrous (only so many people can use a bridge at once). This m

There are some limitations on such balloons already. For example, if the payload is 4-6lbs, stricter rules apply if the weight/size ratio is greater than three ounces per square inch (measured by the smallest surface on the payload).[1

The uAvionix ping200X weighs 50 grams according to its datasheet.[1] With a 1.5W continuous power draw, a 60 gram lithium battery would power it for 8 hours, for a total of 110 grams. WindBorne balloons weigh 1.1kg at launch (including ball

The FCC requires that airborne transmitters identify themselves by broadcasting the an FAA designator such as the aircraft registration number.[1] The FAA has no identification or registration process for small weather balloons. So this eff

Weather balloons already have restrictions on weight to minimize the consequences of collisions. The issue is that even if you can add a transmitter and meet the weight requirements, it's currently not possible to legally broadcast ADS

If you put 170k miles on a gas car, wouldn't you have paid for $10-12k in maintenance over that time? At that point you've done 20 oil changes, replaced the spark plugs & air filter 5 times, replaced the timing belt and transm

The highest numbers I can find for the final Starlink constellation is 40,000 satellites. Let's assume Starlink and its competitors have constellations totaling 100,000 satellites, and satellites need to be replaced every five years, a

If the vaporized satellites were entirely converted into a compound that was as damaging to the ozone layer as the most potent CFC (R-12 [1]), and the compound stayed in the atmosphere forever, it would take 5,000 years to reach current atm

Current Starlink satellites are 800-970kg[1] and 100% of their mass is vaporized on reentry, so 1-2 satellites a day would be approximately 1.5 tons per day added to the atmosphere. The atmosphere's mass is 5.15 quadrillion tons. Even

You can buy a mini on secondary markets. Some are even new in box, though you might need to replace the battery. Until about a year ago, Apple had 13 minis in their refurb store.[1] That's where I managed to get one. I'm going to

Apple and Google make apps exclusive all the time. They just do it by acquiring the company that developed the app, then integrating the app's functionality into their OS. Examples for iOS include Siri, Dark Sky, Shazam, and Workflow.
