Among the top 10 worst parts of America is that it is now anti-Israel anti-semitic hate speech to be critical of that reaction tweet. 50/50 on whether empathy for the 6th grader will be hate speech tomorrow.

It's been a while, but in general based on having too much solar tilted +15 from latitude to maximize winter production, and relying on 14 sun hours/week as a minimum, even if 20 -22 would be expected average. While solar has fixed bs/costs, an extra 300w is fairly cheap, and adding to that often less expensive than more btu (or kwh) storage, or more insulation. Monetizing summer surpluses into crypto (back then) or gpu dataserver rental, also means never having too much solar. Full ROI on all solar, compared to overdoing it on heat storage.

In 25 years time will batteries be cheap enough for us each to have a MWh in the loft?

At $20k/$30k per mwh would make 100 kwh $2-$3k. 100kwh would still be more than you need, and so it is pretty affordable now.

There are some cheap/"bad discharge rate" chemistries like iron air. They'd be too heavy for loft, but could be foundation walls or crate in your back yard. Not a technology likely to be mass produced enough, and shipping costs very high.

What does the world look like when every home has the ability to be energy self-sufficient using solar?

We were at this point in 2019. The raw materials are 1/3 the price today. 100kwh is already more than you need. Corruption of tariffs, and artificial price barriers by electric monopolies and their regulator minions inflate prices in our countries.

I don't know. Wanted to link ep2, but my hacker foo is from a 90s Angelina Jolie movie.

Flooding levels updam is a concern (but not for Hoover) in general. Yes, daily/weekly flow rate downstream is also a concern. But not hourly flow rate.

then our lives are dictated by CBC meal mouthism. It is a bad rule, IMO, even if excessive editorializing is a good rule.

Ain't nobody never asked for any of this, but it invaded my home computer too!!! IPv6 rapist immigrants are taking over this country.

Title is honest summary of Ford positing/request OP title. With focus on key quote Ford is gaslighting us in substance of article.

Title is not editorializing. It is just focusing.

But there are sensible paths to going off grid. Why you would write about an impractical fantasy path was my puzzlement.

I did math for Toronto, Canada. 2000l of hot water was enough (2m^3^). Winters here have gotten cloudier from great lakes warming. Instead of more water as a buffer, dirt is much more space efficient, and just needs the hot water routed through it to get heat transfer.

The volume looks more like a room than a box, unless you can somehow make it molten that is

If hydronic heating system was already being directed towards outer walls instead of straight up from water storage, then a tall "hot dirt" storage, and dual cold water mixing valves (pre and post dirt flow) next to each other, it's less in additional storage costs per heat unit than water, though it does use more electricity to input heat compared to heat pump.

No need for temperatures higher than melting/softening point of copper to get useful heat storage for a home. Just water can be enough if you have the room.

Ok, to be polite, you were just mistaken in portraying a 1 mwh battery as a reasonable idea. It is just so absurdly stupid that motives for the proposal need to be looked at. I accept your admission of stupid instead of evil.
