Is this a thing now? You’re trying to turn it into a thing, right?

Haven’t I read this comment somewhere before…

Is the decade long transition period really over?

It’s a tradition at this point. If you post an infographic about unix/linux system folders, you’re obliged to avoid all modern sources. Preferably, you would use material that is at least 20 years old.

Here’s an idea. Once you’ve already split the water molecules with electrolysis, you should throw those streams into separate mass spectrometers, but without the detector obviously. The idea is, that with ions flying in a magnetic field, their mass would determine where they land. Anything that isn’t the right kind of isotope, let alone right kind of atom, would be separated into the waste stream.

There’s also a huge 0-wheels market. Just think how cool wheel-free skates and boards are.

That keyboard thing was pretty clever. I would not have thought of that.

I think we could send robot farmers there to grow some food for the people living in orbit. Maybe low-G carrots could be nicer than the ones grown on earth.

Humans are very picky. Must have certain amount of gravity, need to see green stuff, can’t handle radiation etc. it’s is as if they were built to be on a specific planet and nowhere else.

If all else fails, use “significant at a p>0.05 level” and hope no one notices.

Business as usual, just another day at the lab. People using actual real world samples instead of the expensive standards to produce a very messy calibration squiggle. Also, the machine probably requires some maintenance from time to time.

Then there’s also the flat-earther style: “We applied a flawed model and flawed methodology to standard circumstances and got the results we wanted!”

I guess we need a new comic to address all the different kinds of pseudo-science.

The universe seems pretty infinite when viewed with our current tools and from our perspective. I would still argue that we can’t really be sure just yet. However, we can say it’s effectively infinite just like a lot of things in physics are effectively massless, effectively frictionless etc. You totally can make your calculations work really well even though your model cuts some corners here and there.

In many cases, you can even assume the Earth is flat and simple maths still works well enough. However, when you zoom out and start doing more complex calculations, you run into trouble and need to upgrade to a more sophisticated model. I would argue that the current assumption of the universe being infinite can fall into the same category.

If we can’t find the cosmic frame of reference, then how do we know it even exists? Sure, you can assume it exists, and call that a hypothesis. If only someone had a way to test that hypothesis.

TL:DR The batteries are based on Iron oxide chemistry. Form Energy is building a factory that is supposed to make the batteries for many grid energy storage facilities, such as the one mentioned in the headline.

Anyway, this sort of development sounds great. This is exactly the kind of thing we need if we are to switch to renewable energy. Li-ion batteries should be reserved for mobile applications, such as cars, laptops, phones and earbuds. There are lots of other battery chemistries available, that have a lower energy density, but they have other advantages to compensate. Those chemistries are much better suited for industrial scale applications like this.

Good point. Sounds like it would be a good idea to replace the RNG chip with a weather station. This way, sunshine, wind, rain, temperature and other conditions control the frequency of the motor. Anyone who can predict that deserves a Nobel Price.

Add a long pipe labyrinth so narrow it will cause turbulence and loose an unpredictable amount of energy that way. The mathematician who can predict how that mess works out gets a noble prize and a pack of drill bits.

If you find out that your current ram is obsolete, you probably have lots of other ancient stuff in your computer too. By the time your ram is too slow or there isn’t enough of it, your CPU is going to be abysmally slow by modern standards. Even if your mobo is still fine at that point, it won’t support any of the upgrades you have in mind, so you’ll end up changing everything anyway.

Build a bund wall, and throw a pump in there as well. Then, just pump the liquid back into the tank to keep it full at all times. In order to deter mathematically inclined terrorists, use a variable frequency drive and make that frequency change every second. The problem becomes unsolvable.

There are other options too. You could fill the tank with tar, any really thick slurry, molten sodium, hydrogen sulfide, 2-mercaptoethanol, propane just to name a few. Drill into a tank like that and you’ll regret that decision instantly.

Can confirm. If you wish to listen to something while in the train/subway or in some other noisy environments, such as a bus stop right next to a busy road, ANC really helps a lot. Obviously, it’s no replacement for proper hearing protection, but instead of cranking up the volume through the roof, you can listen to things at a very reasonable volume despite the noisy environment.
