Engineering. Especially manufacturing. Is awesome. Love how she blasted hydrogen off the bat. I seriously thought I was going insane about how bad hydrogen is for anything except niche projects. I don't understand it. Yamaha even just showcased their hydrogen ICE. Which is like... So terrible of a fuel.

No way in 100 years we are going to print things atom by atom. You all have zero faith in material science! We already can in a lab. Imagine if we could build withcarbon nano tubes and graphene at large scale. Print in on site with robots. Just aren't close for now. This isn't the end of massive turbines. We will go bigger one day for some reason. Control the weather or something.

If nuclear actually ever fulfilled the promises it always makes i would be down with it. Yet it does not. It is always exceedingly stupid expensive. It always takes a ton of water. Factor in the cost overruns that inevitably always happen. 17 billion as we speak for the one being made in America. Two in Europe which are also struggling. While wind and solar along with batteries are dropping year after year. Also again as you said long term waste and containment is never there. The only idea I can get behind is turning old power plants into nuclear. That is it. Outside of that ill take solar, wind, and large batteries of different types. Pumped storage to X battery chemistry. Oh PS. People also are forgetting about the benefits of not having all your eggs in one basket. A decentralized grid is a good thing. How about instead of huge nuclear plants that are mega projects. We literally give people subsidizes to make their own solar and wind where possible so that kills two birds with one stone. How many homes or towns could you power with the same amount of money? Instead of making one huge farm/plant. You set up ways to pay for the solar, wind, and a battery in full. This would drop prices further too for said systems as who would say no to that?

Lead acid are not great for a few reasons. They have low discharging traits which means they tend to deteriorate if you drain them too often. The levelelized cost isn't there either. It is okay when your alternator will cap it off in a car. Not so much at home. I have seen some online use huge banks of them for their home storage. I think used car batteries no less! Seemed to work to me, but I don't know enough about their particular set ups. So it definitely can be a solution, but honestly now there are a lot better ones especially for energy grid storage. Which I think will be dominated by other chemistries or battery types. Some redox batteries look promising. I will take a lead acid battery over cuckin Energy Vault gravity bricks!

Yeah. In a perfect world. This will be a great idea. In reality. Trusting your energy needs to others is foolhardy. We learned this with Russia. Just because it is renewable doesn't mean it is any safer. The entire point of renewables for me is energy security, and decentralization. Getting the shackles off of the middle east. So we finally get rid of the islam fundlementist. Just to put our power security into the ocean where any nefarious actor could cut? Naah. I like energy security.

Didn't people learn trusting your energy security on others is just dumb? Thought Europe specifically learned this lesson. Now we want to cross countries, and put our energy security into the sea. Where bad actors can destroy it? No thanks. Batteries and renewables all day long. I mean I can't wait to leave the Arab countries in the dust. Yet we would be losing one shackle just to create others needlessly.

I don't ever see this working for commercial power anytime soon. I mean it would be awesome if you could get it to work for your home, but do we really want that? For camping, disaster, or the military? That is what I would be going for. Imagine having a small generator you could carry in a backpack for instance. PS: Can just use hydrogen to launch the soft ones when no wind is available. I also remember someone talking about a design for a hybrid airship one that also had a turbine on it. It was tethered and moved up or down.
