No that would be silly. They use the area just before the event horizon of a black hole because they can send the corn dog around and get it back nice and hot just before they sent it.

Get out. Next you’ll be saying they hypothetically use stars to reheat their frozen corn dogs.

The soviets did it in the 1970s. Not sure what you are talking about. It's not a difficult biology problem.

I don’t think anyone’s gonna read the headline and think “oh my, not only did they discover aliens but the first they’re telling us is how their computers work before announcing the discovery of said aliens… Neato!”

Glad to see I wasn’t the only one to see this post and immediately think “well that’s fucking stupid”.

I think common sense would indicate this is clickbait.
We are significantly behind the point of anything like this being perceivable by us

Where do you think that water is going? It goes back into the water cycle and eventually the ocean. We cannot possibly remove enough water from the ocean to make a significant change. Where would we put it? The hydrogen made gets burned and turns back into water which returns to the water cycle as precipitation.
Also you're not adding salt, the salt came from the ocean in the first place.

Yeeeeah, my mistake responding to you basically at all. I'm sorry.

Getting all this calories from a few tablespoons of material just isn't going to happen. We also don't have fucking light bulbs brighter than the God damn sun.
Besides, I've went and looked shit up, you're the one making erroneous claims and when I did the research you just shrug it off with "but i mean it COULD happen you don't know unless you can spend far more than most scientists use for research".

I mean, do they really know your whole psych profile either?
And then they'd kinda be assholes, but again, we give out our info freely already.

You get the energy from surface solar panels.

? So your argument is to compare actual biotech to late night informercials?
Ultimately your argument comes to energy. Each gram of algae can fix so much carbon as sugar per unit of time given max usable sunlight. How many grams of algae do you need to fix enough carbon to keep a human alive.
The algae has not been genetically modified to make more sugar because humans have not needed to do this yet, so I don't know why you have to resort to comparing to random scams.
To disprove my claim you would need to find at least 1 billion USD spent annually on this type of biotech. If it's not being spent this approach has not been tried, and you cannot claim it won't work.

I'll explain like you're 15.
Hydrogen is envisioned by many in the clean energy sector (and the not so clean energy sectors) as a potentially powerful medium of energy storage as a chemical fuel. It has many potential applications if it can be produced cheaply at scale with green energy - steel and concrete production, sea-based shipping, aviation, grid scale energy storage, and several others. It can also be mixed into diesel engines to partially offset usage of carbon-based fuels, which is useful because diesel engines have service lives lasting decades. So hydrogen is a big deal if you're serious about decarbonization and knowledgeable about the challenges.
The problem is that pure hydrogen is rare - it's usually part of other molecules. To get hydrogen we have to split up those molecules. Water is very appealing because it doesn't emit greenhouse gasses as a byproduct - electrolysis of water splits it into hydrogen and oxygen using just electricity. But freshwater is a limited and dwindling resource. Seawater by comparison is plentiful. But it poses challenges for electrolysis - seawater is corrosive, seawater is impure, seawater is the domain of the Deep Ones and their dread flesh constructs. We simply don't have a great way to make hydrogen from seawater at an industrial scale.
This research presents a method by which to produce hydrogen from seawater that somewhat alleviates these challenges. It's early yet, but these are the kinds of things we need to figure out if we want to start building a real hydrogen economy and phasing it into those applications.

I believe I’ve read hydrogen could be used to power jets. That would be an incredible reduction in emissions.

You add salt but take out water, now imagine that on a worldwide scale over 200 years

Not really. The salt is going back into the ocean, where it came from. The gasses were releasing from the ground or somewhere else that is not the atmosphere.

It’s just theorizing about what would something we could detect were it out there. Coming up with something that would be theoretically possible and how we’d be able to detect it were it out there
Gotta theorize about one to detect the other… and gotta get clicks with outrageous titles

So, we'll all be mole people? Given the amount of land I already talked about, trying to put that all underground makes even less sense.
A small enclosed area propped up by the buildings themselves, would potentially make sense, you'd still be able to get sunlight for energy and growing food, it's just not that practical to do that for like a few dozen square miles. But it's a hell of a lot more practical than essentially doing exactly that but also digging out a few dozen square miles of underground territory...
As for blocking blasts - why. Radiation could be as simple as water, tbh. It's what we use in nuclear reactors NOW. Iirc a 30 foot deep pool with nuclear shit at the bottom, you'd be safe from the radiation on the surface.

And now it's being ass pulled.
Look, you're just not getting that kind of calories into that small, that fast growing a thing, and that's fine. Even lower calorie plants, aren't great - a solid carrot is still like 30 calories.
Surprisingly, these seemingly miracle foods, cures, etc generally aren't. If it's too good to be true...

Over time that causes small salinity percentage changes in ocean water. While it would slowly diffuse into the oceans given turbity, in the short term it might destroy the local ecosystem. Many creatures are very sensitive to salinity changes. Accidentally kill off the base of the food chain or a keystone species and say goodbye to all creatures in those waters.

It kills a lot of fish when you do it. Brine is super toxic locally if you just keep dumping it, messes up the waters salt level, ph, etc
