Burning... can a burning chemical reaction be compared to a eletron energy reactions ?

I didn't heard this argument in any skeptic critic to the Goodenough&Braga's battery.

found several years worth of good data for a 50kW solar PV system in Ithaca, NY. 13.7% capacity factor for the lifetime. Located at an intentional community so it gets the best care, snow removal, cleaning.

The only one that might be more energy dense is oxygen iodine, like for a laser weapons system.
Regular gasoline is like 100x as energy dense as lithium ion by weight. Don't know how burning aluminum would only be 5x as energy dense.

That's the problem with rechargeable batteries; even if we double the energy we're still 50x less energy dense than petrol, and it isn't clear that nature has allowed a chemistry that dense/cheap/practical.

Of course. Energy is energy. The international scientific unit of energy is the Joule.

That's 60,000 kWh per year. At my 8 cent per kWh rate, that would be $4,800 year in electricity. How much did the system cost?

I noticed in only a few years of collecting data, some years had 60% more sunshine than others. That's a huge fluctuation and completely unpredictable from the standpoint of creating a stable and cost effective grid. The daily variance was as much as 10x, which is huge.

Colonize the ocean? Subsidize houseboats--mobile homes that can sink!

How many houseboats would you need to add to the ocean in order to raise the sea level a significant amount?

If we replaced all cargo ships with zeppelins would the sea level drop appreciably?

See the link.

https://en.wikipedia.org/wiki/Energy_density

It's about 53 times the energy of the best lithium ion battery.

Gasolin reacts with oxygen, so the gasoline itself have 1/3 of such energy ad the oxygen have 2/3. But cars don't need to cary oxygen like rockets need.

Combustion engines it's just 25% effective in most cars, while some electric motor can be 95% or even 98% efficient. So you have to consider it.

That $30,000 solar power system will leave you with seppuku level buyers remorse.

To go off grid and live like a normal person you probably want at least 20kw of panels and 50 to 100 kwh of battery, a 120/240v15kw generator minimum, a 2 to 3kw dc generator.

For a 60kwh grid tie only system hopefully they didn't pay much more than $80,000. But that number could get a lot bigger when you have to run 3 phase 4160v lines even a relatively short distance.

The cheapest pricing I have seen in the NY area is from Renovus on community/ shared grid scale installations at $2.20/ kW installed. So the Ithaca group's 50kW system would have cost at least $110,000 and have a 15 year pay back at $0.12/ kWh if the electric company gives them the very generous situation of buying any instantaneous excess at the "meter runs backwards" price. If they only received the true spot price for their excess they would only get back around $0.04
.
State and national rebates would give back an additional $60,000 of the installation price. And they might even qualify as a "grid scale" installation which unlocks a further $0.03/ kWh federal "feed in tariff" reimbursment.

20kw of panels ???
So so much for a minimum to live like a normal person?
20Kw of panels it's 60 large panels (330w each). It's about 5kW of constant power in average per hour (including night with extra power of the day stored for night)
Why that much?

Todays light it's from LED and not incandescent bulb.
PC take 200w or 250W. A TV 80 or 100W. And you sleep 7 hours and don't stay entire day in home.
Hot shower can be from solar heater and not photovoltaics.

So I ask, why that much panels needed ?

I can think of one big positive of climate change. The end of the last ice age.
That would be 8,000 years ago.The Climatic Optimum.
Canada and Scandinavia were still experiencing 8-inches of tectonic rebound/year,as of 1976,as a consequence of the weight loss from the melted ice sheets.
The tectonic stress from the shifting weight distribution has some volcanologists fearing that explosive eruptions could be triggered,which accompanied ice sheet dynamics over the last 2-million years.
If it were to happen en mass,we'd go into an ice age from all the ash plumes.
