I bought an old Nissan Leaf last year. They're actually cheaper than gas cars of the same year. This summer, the weather was nice, I was remote working and I decided to get into a park under a canopy on a picnic table. I took a 50ft el

I'm gonna be the annoying guy who points out the obvious thats being repeated again and again for the last 50 years... For transport, trains! Trains of different sizes, shapes and designs, solve most of the transport issues. The fact t

Not only that, but there are quite a few scientifically sound concepts that escape the tyranny of the rocket equation. Pre-seeded trajectories, particle beam propulsion, sails etc. Breaking the wall of light might not be possible but beatin

Also my recommendation: -Make the card vertical instead of horizontal (phones are held vertically) -Add a +/- bottom on each end of the slider for fine tuning the ppi by 0.1 increment or lower, -Allow to manually change the value in th

Molybdenum and tungsten both have melting point much higher than silicon, Maybe these circuits could be a good candidate for Venus rovers?

A few years ago a popular idea was that our universe existed as an hologram on the surface of a black hole. Recently I saw also a theory that black hole might not, in fact, exist as we thought, and may be instead something called 'grav

There's an interesting implication to this. We assume that evolution happens when random mutations (similar to random bit flips, removal or injection?) occur and when the random result has an advantage, the mutation tends to remain in

ZBLAN is such a material, a type of glass much more transparent than silica glass and could be used for fiber optics. It has been tested on the ISS. A similar fictional material is also at the center of the plot of the novel Artemis by Andy

I think the parent comment exposes the obvious flaw of using plasma to drill: Drilling with diamond bits uses fluid, which is uncompressible. Drilling with plasma uses gas, which is compressible. No matter how thick the obsidian layer get,

You could probably use significantly less coolant if you're using heat pipes. The coolant is mainly gaseous and only a small mass remains liquid during the cycle

Cult member here. I started listening to audiobooks (not this one) about 5 years ago, after a job transfer that meant driving 2 hours a day, in slow traffic, with little attention needed (due to a tunnel repair that will likely take decades

It feels less like a word prediction algorithm and more like a world model compression algorithm. Maybe we tried to create one and accidentaly created the other?

Not sure what functionality is not covered by current cables. Both my laptop and phone, which are several years old, use the usb-C connector for power, data, video, audio, and combined with a hub can connect to any usb peripheral out there.

I learned to drive with a manual transmission so I'd feel comfortable driving any car in Europe, where manual transmissions are far more common. The transition was stressful but after a few hours it became easier and after a few days,

I like to refer to this kind of article when a kid has trouble understanding why they need to provide sources in their homework. Sometimes it's difficult for them to understand that this kind of assertation, that people use constantly

I'm curious about the Aldrin Cycler analysis. Isn't the whole point of the "castle" to house travelers and life support system in a larger habitable space during the long travel, independently of the cargo required for

Artemis by Andy Weir dwells a lot on this kind of infrastructure, but I never could understand the orbital mechanics described in the book.

I don't think this result reflects all antibiotic treatments: "RESULTS Oral antibiotic treatment disrupts the colonic mucus barrier" Intraveinous administration may or may not cause the same effect, or a similar effect. Maybe

Heat released by global human energy consumption, every source combined, is insignificant compared by heat received from the sun. (quick calculation 17.7TW / 173PW= 0.01026%). Global warming is caused by greenhouse gases trapping radia

Keep in mind that there was nothing indicating that the sun and the stars were of the same nature, or that they were so far away. When you think about it, all stars appear equally distant to the naked eye, so the idea that stars were fiery

Here's what I understand of this, correct me if I'm wrong. If 1 kg of matter and 1 kg of antimatter annihilate each other, their entire mass is converted into photons, which are massless. If said photons are entirely absorbed by a

If your camera app has a manual setting, set a 5 second timer and a 30 seconds exposure, then put it on the floor, face down and camera up. If you want to angle it in a specific direction, a small plastic bag with sand, earth or rice in it

The simplest capture device you need, you probably own already. A long manual exposure of around 30 seconds will give out magnificent pictures even with the most potato of cameras

Sorry,I'm confused. Aren't podcasts audio by definition? Unless your audience is going to be mainly on a video platform (and even then, the following advice will apply) you should focus your budget on audio equipment, and possibly

About point 2: in my neighborhood there's half a dozen kids, all aged 5-8, all communicating constantly during weekends using cheap, loud FRS walkie talkies some parent bought in a 10-pack off Amazon. My point being that even without i

Some Youtube folks tried a much simpler approach: Take a large metal bucket or barrel. Put a heating element and a simple oven thermostat on the bottom. Fill with sand. Connect to a solar panel or other enrgy source. The air between the san

One could build a service just around the fact that the fastest theorical time it takes to transmit information around earth is around 130ms. This means that the absolute maximum number of layers that could be used in a day is well below 1
