- Comment on Kinetic Energy 👟⚡️ 3 months ago:
What I want to know is, how much energy was used to create these floors, install them, and how much energy will be required to service them (the electronics) if they break down over the useful life of the installation, including how much energy was spent on resource extraction and processing.
Then I want to see that number compared as a ratio to the amount of energy these floors can generate over their expected useful life span, say 15 years in high pedestrian traffic areas.
I am highly skeptical that the ratio would even approach 1:1, I expect a net energy loss. But I could be convinced otherwise with some good data.

Adding Solar to More Devices
I never understood why this wasn’t more common already. … Why not? Seems like an obvious solution…
Good question, with a simple engineering answer: often times the energy cost of creating these solar panels and installing them into devices is considerably higher than the amount of energy those devices could possibly except after many decades of constant use. The point at which the solar energy collected matches the energy cost to create and install the device might actually be longer than the life of the solar panel or the device itself. So adding solar to every last little thing will actually cost a lot more money for consumers while causing more harm to the environment.
That is not to say that solar is always bad, in fact solar is incredibly good when used at industrial scales, especially in power stations, and on the rooftops of factories, shopping centers, data centers, and warehouses.
We see too often on the news stories about how some amazing invention might help solve global warming, but this is often just propaganda. The oil and car companies want you to think buying more technology from these tech companies (which are often their own subsidiary companies) will solve the problem. But really it is just another way of profiting off of people without doing any of the hard work on the energy transition themselves.
- Comment on US Air Force successfully tests AI-controlled fighter jet in first dogfight against human pilots 6 months ago:
It was also the plot of the Terminator series of films. Well, except for the detail that the AI controlling the aircraft (called “Skynet”) became “self aware” and that is what caused it to launch all the nukes to kill all the humans.
So how it differ from Terminator’s “Skynet” is that these real life AI are being controlled by genocidal maniacs (the largest concentration of whom seem to live in the US and Israel at present) and they are setting these things to “auto-kill” mode, like what happened in Gaza recently. And the genocidal maniacs gleefully ignore international law, saying “you want to stop me, you and what army?” So who is to keep them from turning the robots against you and me?

I am upvoting this thread for being relevant to the discussion, but man, this article makes me sick. They are completely ruining Star Trek.

they’re not really illegal at all, are they?
If a police officer commits murder but the D.A. covers it up and the officer is never charged with a crime, does this make murder legal?

“Illegal?” DS9’s S31 was protected by Starfleet Command. They were completely untouchable.
They can be both protected and illegal. Sisko noted that the organization was completely antithetical to the laws of Starfleet, but their existence was neither denied nor acknowledged by Starfleet. This is part of the reason why he asked Bashir to act as a double-agent.

Deep Space Nine made it absolutely clear that Section 31 is an illegal black-ops org with garb somewhat reminiscient of Nazi storm troopers.
Yeoh has described it as “Mission: Impossible in space,” and likened the tone to the Guardians of the Galaxy movies.
Mission: Impossible, the longest-running, pro-CIA anti-communist propaganda series in US history making illegal black-ops Nazis look cool.
Fuck these fucking producers. I want my gay space communism back.

Cool, I hadn’t thought of that. Thanks!
- Comment on Pretty cool fan made intro to a non-existent show 9 months ago:
Wow, I am impressed. I am just finishing up the entire Deep Space 9 series, this really adds to the ambiance for me.
I am so curious where they got all the 3D assets for the Defiant, Deep Space 9, even one of the Orb of the Prophets… did they actually do all that by hand? These aren’t just available on Thingverse or the Unreal Engine Marketplace, right?
- Comment on Gravity Storage 101 Or Why Pumped Hydro Is The Only Remotely Real Gravity Storage 9 months ago:
There is only one other gravity storage system that I know of that isn’t hydro, but it isn’t really a storage system. It is the Forterra ropeway used by a quarry in the UK where buckets of minerals are sent down a rope line similar to a ski lift. Since the quarry is uphill from the processing area, the energy from the material traveling along the rope is used to pull up all the empty buckets. Tom Scott did a YouTube video on it: www.youtube.com/watch?v=6RiYXI1Tfu4
I don’t know why they didn’t just put the mineral processing area closer to the quarry, maybe it moved over time?
But anyway this is the only example of a viable gravity stored energy system that I know of that is not pumped hydro.
