Earth orbit is getting more and more crowded, with both active satellites and pieces of debris. There's so much stuff up there that it's far from alarmist to start worrying about the Kessler syndrome, a nightmare scenario in which a collision or two leads to many more, vastly increasing the amount of junk circling our planet.

“We have to get serious about this and recognize that, unless we do something, we are in imminent danger of making a whole part of our Earth environment unusable."

Most of those LEO satellites — about 6,800 of them — belong to a single constellation: SpaceX's Starlink broadband network. The vast majority of these warnings involve Starlink satellites, which are far from sitting ducks. These spacecraft use onboard software to spot possibly worrisome encounters and perform evasive maneuvers if needed which other satellites cannot.

These numbers are growing all the time, and the tally could soon get mind-bogglingly high. SpaceX, for example, wants the Starlink network to eventually harbor more than 40,000 spacecraft.

Other players aim to build their own broadband constellations in LEO as well. China has begun building out its Qianfan ("Thousand Sails") megaconstellation, which will feature about 14,000 satellites if all goes according to plan. In addition, Amazon intends to assemble its own 3,200-satellite LEO broadband network, called Project Kuiper.

These satellites are having more and more close encounters with each other and with pieces of debris. Indeed, there are about 1,000 collision warnings per day on average in LEO. Earth orbit is getting more and more crowded, with both active satellites and pieces of debris. There's so much stuff up there that it's far from alarmist to start worrying about the Kessler syndrome, a nightmare scenario in which a collision or two leads to many more.

The poll lists several electronic devices that many people use.

The question is...

Which one of these electronic devices do you use the most?

Please vote in the poll.

Note that pictures in the poll are just examples, not specific types or brands of devices.

I didn't include nuclear. My reason being that it's not really natural as much as I support nuclear energy 100%. I also think by early 2100s room temperature super conductivity will be a reality on the grid so heat loss through electrical transmission will be solved.

Anyway, all have their pros and cons. I think tidal & geothermal have REALLY big potential. My local utility is subsidizing under ground heat pump installation and some municipalities are experimenting with tidal generation; there is so much unused water front property that it just makes sense.

In many cases, a combination of these innovations is energy neutral like using solar to lift mass for a gravity battery to run at night.

Fun fact: ONE space elevator with a gravity generator & a large (were talking hundreds of sq km) solar power array can generate enough power for entire 1st world nations.

What's more valuable to you?

Tesla is a company known for its electric vehicles, innovation in battery technology, and self-driving advancements. However, opinions on the company vary based on factors like its leadership, business practices, and environmental impact. How do you view Tesla overall?


I view Tesla positively from a technological standpoint. Their advancements in electric vehicle efficiency, battery technology, and self-driving capabilities have pushed the industry forward. However, I acknowledge that some people have concerns about their business practices, leadership, or the practicality of EVs in certain regions. Overall, I see them as an innovative company that has had a major impact on the auto industry.
