Well anyone can 3D print something, but it’s the modeling of a printable object that is your skill. However modeling and designing are two different things.

If I had your equipment and skills right now I would start printing bathtub jet plugs. Convert a jetted tub into a non-jetted. Probably only a few different brands and designs to cover.

Aside from that, I’d get into mold making. You can 3d print a mold, or even a mold of a mold. Or a mold of a mold of a mold. Then you can cast objects in metal or ceramic, or silicone or even plastic (haha) or other materials that can be a liquid. Way more interesting than plastic shapes. Plus molds can be used many times.

As far as the business goes? No idea. Start by making useful objects that people want to buy. But that’s kind of a different skill of “inventor”.

I was just thinking about this. Love these videos. Cooling of a solar panel is a good application, as long as it gets cold enough for long enough to re-solidify at night.

An alcohol/NaCl solution with a stabilizer can make an ice pack that freezes colder than water. That could be used to keep ice cream frozen in an ice chest.

It would be cool to have recipes for a few different temperatures. There’s a German company Qool Products that sells PCM temperature elements (ice packs), at a variety of temperatures, to store ice cream up to red wine/cellar temp in their ice chest. With some trial and error I guess we could now make our own!

There are plenty of protected lanes in my city, but they just hide bicycles behind parked cars, making it less safe at every intersection.

The only way I can think that might work better would be to convert a 3-lane road (with suicide/turn lane in center), into a 2-lane road. The center lane gets converted into a two-way bicycle road - raised up like a sidewalk with curved curb. No left turns allowed for cars, only right turns. This way bicycles are visible and protected.

Yeah it’s typically not used for dosages, rather it’s for concentrations in solution. However strictly speaking the grams cancel in the units of ng/kg and you are left with ppt. I think of ppm and ppt as very small percentages anyway. As per cent means part per one hundred. Can’t use “permille” because it means part per thousand but sounds like part per million.

In the case of a lethal dose, I think it would be fine to say, “it’s lethal at a rate of 2 trillionths of body mass”.

2.1 ppt (parts per trillion)

I would be an inventor. I would be an explorer. I would be a teacher. I would be an artist. I would be a musician. I would be an entertainer. I would be a builder.

It’s explained pretty well in Optical Physics for Babies. Take a peek in the kids books section next time you’re at a book store. It also explains double rainbows, and why the second one has the colors in reverse order and is always more faint. This is a detail they got wrong in my favorite episode of Bluey: Rain.

There’s been talk of some crops being able to be grown further north or south. But most of the weather patterns of a region are a function of proximity to ocean, predominant winds, and topography. It’s important not to confuse weather and climate. For a given drought or flood people may want to point to climate change as a cause, but it’s only going to amplify patterns that already existed.

Climate change is moving water around, not creating or destroying it. Warmer air holds more water, so overall, the atmosphere can hold (and at times drop) more water than before. Permanent ice is melting as well, so that puts a bit more fresh water into the air and ocean. The water in the atmosphere is constantly circling the globe, forced largely by the rotation of the earth. Warmer temperature also makes for more evapotranspiration, so more fresh surface water is pulled into the air. But that same water will eventually fall elsewhere.

The sun is the source of energy that drives wind, rain, and evaporation. When you trap more of that energy with GHGs, it just turns up the volume for all of those things. There’s always seasonal and geographic variability, but the extremes increase because all those phenomena are solar powered.

Brush up against one and you’re assaulted - it’s like skunk spray in the plant kingdom.

For me peanut butter is not as bad as dry roasted peanuts. For some reason before they’re pulverized, it smells like cigarette smoke to me.

I hate when a restart fixes it. It means it will never be fixed.

Somebody has to make the call. There was this dinosaur book for kids in a little free library. It didn’t even have an author or publisher, because it was AI garbage. Full of misspellings, etc. I contemplated throwing it in the trash because I don’t think it should exist. But for some reason I had trouble deciding that for others.

Digitize and delete? Scan straight to OCR and dump the books. One hard drive can store a lot of books.

Try it. For me it works better than Google Maps. Another option to consider is Organic Maps.

Just ban plastic surgery from the contestants.

Imagine if you played Suika, how you’d look at fruits.

In California we have a project called Flood-MAR, which stands for Managed Aquifer Recharge. Farmers who have land that wont be damaged by floods volunteer to pump lots of water onto their lands during floods. This reduces the downstream flooding slightly, and the water soaks deep into the ground for safe keeping until it needs to be pumped up during a drought.

I think it would be cool if you were writing a ransom note on your computer, if the paper clip popped up and said, ‘Looks like you’re writing a ransom note. Need help? You should use more forceful language, you’ll get more money.’

Canoo if they every exist IRL.
