Forget the technical BS of this moron, lets focus on the gofundme nonsense.
So I pay into this gofundme thing and that makes me partial owner of that bridge, just like the others who participated. In what fantasy world do you live if you think that bridge will not be blocked for all others who did not participate? Will the people out of the kindness of their hearts allow others to cross that bridge?
If you believe that this bridge will not cause people to throw hissyfits and consider it private then I have a bridge to sell you 😂This is the kind of person who thinks you can grow and sell a million tomatoes in one year. It’s all about “the hustle” - physics and reality be damned.
You can grow a million tomatoes alright, what you can’t do is sell them:
- 30% will be misshapen, so you’ll have to throw them away
- 40% will have some blemish, arrive a day too late to the market, or just be the wrong color and no shop will buy them… but you might be lucky and sell ½ of them for katchup and similar, so that’s another 20% getting thrown away
- 10% (⅕ of the remaining ones) will not get chosen by buyers, and go bad, so… whatever, that’s the shop’s problem now 😁!
Congrats, you just sold 500 thousand tomatoes!
And is that huge 3D printer in the room with us now?
Unfortunately it’ll take 10 years to build the printer.
And even then, the filament needed at this scale will take another several years, and a few days for shipping.
Also, it doesn’t do well in sunlight or high humidity for prolonged periods of time, so we’ll need maybe 20 to 30 years to work out a solution for that problem.
I can only assume they’re trying to talk about concrete 3D printing, but oh boy is that not ready for anything which needs strength.
How weak are we talking? All I’ve seen is the press releases from the companies that do it.
.
Yeah, but how much worse than normal unreinforced concrete? (Which is actually fine if you aren’t worried about tension)
Oh it should be roughly equivalent. But really, what besides a slab can you build without worrying about tension?
