Climate in the 21st Century

Why do you want to heat hot water? I bet you own a hot water heater, you magnificent redundant bastard....
Interesting video though, i think there are going to be lots of little solutions to compliment the big ones...Now if we could just get going on those big ones.

I liked the pry my gas stove from my cold dead hands angle, no need! Technology pulled the rug right out from under their feet.

I really like the ocean water tower idea and I hope further studies work out; it looks like they did their basic homework. These 150 X 200-meter structures are not hard or expensive to build with reinforced concrete and can be built right on the water like D Day Mulberry harbor break waters, towed to the location and controlled sunk and then sucked into the bottom by hydraulic pressure. 150 meters above the water is a great place for wind turbines to power the whole setup with batteries in the ballast below. Even deep-water California has sea mounts and islands offshore or these could even be floating structures in deep water anchored to the seafloor and pumping millions of gallons of fresh water ashore using sunlight and wind power. It might even be combined with carbon capture and serve a dual purpose. A really neat idea that could solve a lot of problems and in a place like California, it would mean more water for inland regions and less required for costal California, pump it into costal mountain reservoirs. Looks doable, cheap and fast, very competitive with desalination.

Mid-decade is 2 years away and this kind of battery will improve and has a lot more capacity than the lithium batteries used these days.

If you look at some solar info domestic hot water takes a lot of energy with electric, though there are efficient designs, but they still take power that might be dumped into the EV or sold to the grid. If you wanna cook using gas, then one or two of these units using sunlight and storing the hydrogen while the sun shines, might make more of an excess than needed for cooking, it works constantly while the sun shines whether you need the hydrogen or not, so after the tank is full it heats the water tank instead of wasted! One or two of these over the kitchen along with PV panels on the roof and a safe cheap sodium battery bank in the basement along with a small hydrogen tank outside could do ya if you live in the right place and circumstances and wanna cook with gas. Cooking and heating domestic hot water are major energy users and will reduce the load on the PV and battery system a lot, so will a heat pump, more energy for the EV plugged in outside.

that still doesn't explain why you're heating hot water....

Preheating it ok!

Preheating hot water suffers from the same apparent redundancy.

Don't! You are technically correct if you were referring to a system with a storage tank, assuming the storage tank is located where the ambient temperature is below the actual storage tank temperature.

But that is (since we’re being technical) not heating the hot water so much as countering its tendency to cool.

It's still a neat idea for those who wanna cook with gas and are fanatical about it and takes the wind out of the sails of the cold dead hands crowd. That's about all I think it would be useful for, unless significantly more efficient and cost effective than PV and then it could be used for heating purposes.

I also think that offshore water tower idea could be very significant if it works out and it looks like it's worth a test and some bucks, the numbers impressed me as did the ease and speed of construction.

That would only be accurate as long as the heat added perfectly matched the heat loss, not feasible outside of lab conditions. DIY gets to say neener on this one. LOL

it’s a symptom of DIYabetes …

Not just EVs, but cellphones, tablets and even drones or electric aviation. Even a 5- or 6-fold increase would be enormous, and you could power a humanoid robot all shift long. Grid, home storage and cheap EVs might be sodium-based batteries, but high performance and energy density will be these, if it works out and no rare minerals are required to bottleneck things. This also looks like it can get from the lab to the fab pretty quickly.

Now imagine the batteries above with a 5X improvement introduced in say 5 years, this pickup would have a 2,500 mile range with the same size pack, more actually, if no cooling system was required for the pack, probably 3,000 miles of range. Mind you it would take a long time to charge from home at 220 volts from flat to full, but you could drive from NY to LA on a single charge! I think people will be buying the same truck cheaper with a smaller battery, say 1,000 miles of range. So much for range anxiety, the sonofabitch could power yer house for a month if topped up!
