Waiting for new nuclear plants to be built.

I don't think that's what they had in mind.

"Of course there are used electric vehicles, but they are still on the upper price end."

'22 Kia Niro EV for $8k net of tax credits is nowhere near "the upper price end".

"Those that aren't have small aging batteries with very limited range."

260+ mile range and a battery showing no sign of degradation.

And free DCFC near me, too.

Good deals on decent used EVs abound.

"Alternatively, on refuelling, tankers could have been used which had a small amount of a different type of fuel (gasolene or kerosene) - which could have dissolved in jet fuel, and would have burned but producing significantly less power."

Where have you ever seen fuel trucks switch fuels?

Aside from that, the B787 carries 33,000 gallons of fuel. That's four X 8,000 gallon fuel trucks, full. At 200gpm, quite a length fueling process.

Aviation gasoline is typically dispensed overwing at dramatically lower rates (15gpm or so) from small trucks.

The situation you propose simply doesn't arise in real life.

"And as others here have mentioned, the weights of passengers, crew, and carry ons, are all calculated using an average weight. Which can commonly lead to the plane being "Slightly over-fueled" and will cause it to get to the destination with a good bit more fuel than its supposed to be landing with. Leading to a dump. "

Yet again you look like you're just making shit up.

There's no need to dump fuel at the end of a flight for weight issues.

And no airline would load more fuel than they need for that flight.

Number of reactors is not the issue.

Aging technical knowledge is.

We played 'Shit on Your Neighbor' with a standard deck of cards.

Same game.

'Crazy Eights' is more tame.

You're the authority now?

Hmmm.

The Farthest

"I could be swayed by an argument that says forcing builders to get closer to passivhaus efficiencies is better than this. But that would be dramatically more expensive, so the pushback would be much greater."

Yet it's not. And the payoff is longer lasting.

2X6 walls allowing greater insulation, high efficiency lighting, heat pumps, ...

Incremental costs are quite low.

1.8 gigatonnes of global annual steel production, essentially 100% iron.

Iron reduction with green hydrogen then needs needs 70MT H2.

Which needs about 4,000TWh of electrical energy.

Or the entire US grid's annual use.

If anyone asked what will we do with the excess RE we need for a fossil free life (with minimal storage), this is part of it.

Another 25MT of green H2 to make green ammonia.

The list of interruptible electrifiable processes goes on, including water deslinization, hydrogen for long term energy storage, carbon capture, methanol and more ammonia for energy use, ...

Related savings include 30% of ore shipping. Which for Australia's exports (half of global production) means 1,650 fewer carrier (170,000 tonne deadweight, ie really big) loads.

is an outstanding documentary on this process.

Definitely worth a watch for those who are interested.

From TFA:
"So many birds have been victims of the plant's concentrated sun rays that workers referred to them as "streamers," for the smoke plume that comes from birds that ignite in midair. When federal wildlife investigators visited the plant around 10 years ago, they reported an average of one "streamer" every two minutes."

One every two minutes works out to 300ish per day.

Yet the data doesn't support the meme.

"In July of 2012, scientists from the U.S. Fish & Wildlife Service Office of Law Enforcement visited Ivanpah, Desert Sunlight, and Genesis as part of an informal effort to investigate bird deaths. Over the course of the next seventeen months, they recorded over 230 casualties of a wide variety of bird species.Mar 5, 2015"

230 per month is about eight per day.

"According to the firm H.T. Harvey and Associates, the Ivanpah Solar Electric Generating System was the site of somewhere between 2,500 and 6,700 bird mortalities in the plant's first year of operation, between October 2013 and October 2014. The firm says the most likely actual figure is somewhere around 3,500 birds killed in that time."

3,500 per year is about 10 per day.

"Of those 3,504 projected fatalities, just under 1,500 are likely to have been caused either by burn injuries from the project's concentrated solar flux, collisions with structures, or entrapment in the project's buildings or other infrastructure, while about 2,000 would be expected to show no obvious sign of those specific causes of death -- raising the possibility, says H.T. Harvey, that at least some of those 2,000 other projected mortalities might have had nothing to do, at least directly, with the power plant."

1,500 per year is about four per day.

every time I remember seeing bitcoin for sale on ebay for about a nickel and thinking, "Why waste my money?"

for the base model.

May as well not even talk about it.

Not price parity. What are the combined mortgage and utility costs? For passive houses, expect the total to be lower than the alternative.

But the mortgage industry is not set up to accept this calculation and home builders are not particularly interested.

Builders do what code requires, no more, with rare exceptions.

Giving them a reasonable argument that banks accept will make the transition _much_ faster.

PS. The parity link is paywalled.
