The black ocean series does a good job if blending the two together. But it sort of sets them in opposition to each other. Interstellar travel is made possible on futuristic spaceships by using magic to plunge the ship partially into another dimension, shortening the relative distance between stars. But unless the it is specially shielded against it, magic ruins and destroys technology.

You clearly don't understand the basic principles of engineering.

They don't float, they're fixed in place at depth. They use the pressure of the surrounding water to spin a turbine as its pumped in and out, the only moving parts are the turbine and its associated components. And seeing as how the water is pumped in and out, most of the silt/detritus pulled in during filling, would be pumped out during draining assuming a siphon tube is used to draw the water from the bottom of the sphere (where all the debris settles) to the pump.

Yes salt water is corrosive, but that problem is already solved, there are currently concrete oil platforms built in the 70s and still in service today. We have formulas for concrete that are proven to be seawater resistant.

Building storage tanks on land wouldn't be as efficient due to the greater pressure differential at 500m underwater vs on land. Dams are one of the most expensive structures to build and are very damaging to the surrounding environment. They also have a much larger problem with silt deposition as there is a constant flow of it, every time it rains there's another surge of silt making its way downstream to be trapped by the dam.

Overall this project would be considerably cheaper, more friendly to the environment, and most likely more efficient than any pumped storage on land. And its not like the sea floor is lacking for real estate, unlike any feasable locations for dams here on land.

That's why I said siphon it from the bottom, a siphon tube going from the bottom to the top would eject the water up and away while still sucking out most of the sediment that had gotten in and settled on the floor of the ball.

I don't see silt being as big of a problem here, if the intake is located at the top of the sphere that puts it well away from the seabed. The only silt it could suck in is what's dispersed in the water already, and at 500+ meters there's very little current to stir it up. And if they put the intake on top and siphoned the output from the bottom it would even be relatively self-cleaning.

I feel like this was created with ai, the angry robot in the first panel has the same hair as the guy. But not in the subsequent panels.

Its the sugar, it slows the curing of the concrete but doesn't stop it entirely. Over about 2% concentration by weight it begins to affect the strength of the finished concrete though.

Sugar in a gas tank will only really clog the fuel filter. Sucrose doesn't dissolve in gasoline. Water in the fuel would be more harmful than sugar.

DO NOT MIX BLEACH AND CHLORINE, unless you want die or seriously injure yourself. When bleach is combined with acetic acid it produces chlorine gas, a literal chemical weapon/warcrime. If you want to corrode stainless steel use regular bleach, it does the job just fine.

It's not right to say that all of his supporters are racists, many of them are for sure. But he also has the demographic of the stupid locked in.

@DemBoSain@midwest.social it masses the same as 555.9 grams of bananas.

 

I propose a new ASME standard, the Scaling Banana™.

 

For your consideration, I submit my design for a new ASME standard. The Scaling Banana.

 

The architects of projects like Próspera are drafting legislation to create US cities that would be free from federal regulations.

 

President Donald Trump is set to sign three executive orders on Monday involving the U.S. military, including banning transgender service members, eliminating military DEI programs, and reinstating service members discharged for refusing the COVID-19 vaccine.

 

Hey all, I hope I'm posting to the right place. My gf and I are both trans women considering immigrating to New Zealand from the US. We both have green list careers so we're not too worried about eligibility but we are wondering if we would be welcome/fit in in NZ.

Everything I've seen or heard in media makes NZ look about 1000 times better than the US. Every country has their problems but from my limited viewpoint NZ looks pretty great. We'd appreciate any advice or perspective you'd care to share. Thanks in advance.
