In Florida, 2023 has seen more storms than anticipated, with August bringing six named storms, higher than the typical 3 to 4 storms. Through 2 October, there have been 17 named storms, including six hurricanes and 11 tropical storms.

Tinkerisk:

But you can't put this stuff into your future classic car, the engine would have to be really historic (from the 80s) and work with a fairly low compression factor - these engines don't care much about synthetics.

What are the octane ratings of these carbon neutral fuels?

I've seen some people talking about ethanol and methanol based carbon neutral or near carbon neutral fuels. Right now E85 and methanol are popular in racing in classes where the rules allow them. You can usually run a higher compression ratio and your engine runs cooler. Porsche is working on a carbon neutral fuel, so that would need to support quite high octanes.

I suspect that these carbon neutral fuel options won't be cheap, but there are plenty of people that don't do high mileage in their classic car and will pay the price.

The problem is less the octane number than the fact that the overall balance of the co2-neutral production of these synthetic fuels requires five times more energy than the direct use of this energy in an electric car - so it really doesn‘t make much sense. I suppose that's why Porsche has e-cars in its range of products. 😉

I wasn't asking about the highest efficiency option. I'm sure that electric public transport is usually the winner in that contest. I was asking about someone that might want to keep a classic car running and was probably doing limited mileage.

You seemed to suggest that synthetic fuels would only suit a really historic car (from the 80s) and would only work with a fairly low compression factor.

My early 1980s Alfa Romeo preferred 96-98 octane when I could get it, so I'm not sure what this really means. There appears to be a certain amount of fearmongering about classic cars being doomed when new regulations are adopted, but on the other hand there are people promising carbon-neutral fuels, but without a lot of detail. Octane number and price are going to be key factors in determining how feasible that will be for people.

We have a 1993 Spider as well (one from the last batch) … so. With additives it will work. But there is still the question of gasket dissolving (no clue what they will put in on chemicals). We think about selling it in the next few years since we will not operate a museum. It should be clear that the synthetic stuff will be sold „in the pharmacy.“

Because in some countries they’re being forced to replace things that aren’t broken at considerable expense (for example gas central heating) and to replace it with things that don’t work as well.

This is fine; the Act party's latest scheme is that the Ministry should not be responsible for setting the curriculum, but rather there should be a marketplace of curriculums which teachers can buy. Because that way we'll get ... better ... curriculums...? Anyway - gonna start writing my science-based, "eat-the-rich" philosophy curriculum tonight which I will provide free of charge across the country.

Companies right to sue for billions in “lost profit” if a country moved to protect its drinking water or the Amazon ecosystem.

The Guardian: The obscure legal system that lets corporations sue countries

Luis Parada’s office is just four blocks from the White House, Washington’s lobbying row. He is one of a handful of lawyers in the world who specialise in defending sovereign states against lawsuits lodged by multinational corporations. He is the lawyer for the defence in an obscure but increasingly powerful field of international law – where foreign investors can sue governments in a network of tribunals for billions of dollars.

Fifteen years ago, his work was a minor niche even within the legal business. But since 2000, hundreds of foreign investors have sued more than half of the world’s countries, claiming damages for a wide range of government actions that they say have threatened their profits. In 2006, Ecuador cancelled an oil-exploration contract with Houston-based Occidental Petroleum; in 2012, after Occidental filed a suit before an international investment tribunal, Ecuador was ordered to pay a record $1.8bn – roughly equal to the country’s health budget for a year. (Ecuador has logged a request for the decision to be annulled.)

It's hardly obscure these days. ISDS agreements were high profile during the TTP negotiations, and the main reason the opponents of the "free trade" agreement actually opposed it...

This is IMHO what's wrong with the modern world... companies feel entitled to make profits, and what's more, required to maintain return on investment for their shareholders. And it's become a cycle where profits -> increase in share value -> pressure to maintain that value.

I have no problem with high profits for innovation and risk-taking, but where there's no risk there's no justification for price-gouging (e.g. banks, supermarkets, petrol companies). And if a company can rely on the government to bail them out when there's some kind of large adverse event (e.g. covid, Chch earthquake), they're not risking very much at all.

Climate change is a real existential threat. I thought my kids - possibly grandkids - would be the ones to see the worst of it. But the bad stuff is accelerating a lot faster than even the climate scientists predicted. Now fully expect that I will be alive to see the upheaval begin.

I feel we are at the start of the Climate Change Bell Curve. One in 100 year and one in a thousand year events is over. They will be regular now, and when the weather and random chance stars align that gives you the 1 in 100 event, that will be huge from here on. Phoenix, AZ, 25 days in a row of 43.3 C or higher that's unreal

Here in ChCh, unscientific obervations this Winter. Hardly any frosts, spring bulbs came up late June. Daffodils in flower. Big dump of rain here last weekend (not unusual this time of year) but it was double July rainfall in 2 days. Last week we had 3 days in a row of 17 to 18+ degrees. Yes, any of these can happen in any given year, but not unusual now

100%. Growing up in Auckland in the 90's we'd have several good frosts every winter - now you're lucky to have one every 2 years.

Skiing on Ruapehu: the permanent snowline would be just above the chateau, (I remember always having to walk through knee deep, sometime thigh deep, snow to get to the club house) now the snow line doesn't even comedown to the bottom lift. Why Whakapapa never moved Happy Valley the old hutflat area is beyond me. But I guess that's now irrelevant since skiing on Ruapehu could well now be non-existent from a business perspective

Been watching Ade's Climate Change doco. Last ep was a Swedish business that runs a green energy company, the house has a lot of solar and the excess is turned into Hydrogen, so his basement that has the mini power plant also has a LOT of Hydrogen bottles that feeds the house at night and when solar isnt enough. He says a decade to get the setup cost to a figure that is viable to add to a standard home. He says Hydrogen is the way to go for power and transport.

I think it's a definite possibility for stationary purposes where it can be used on site as produced (e.g. industrial hydrogen), and with long term storage for power production. But given all the other reasons we all know about, I don't ever see it overtaking batteries for light vehicles now. The only advantage it ever had (fast refueling) is already basically negated between bigger, cheaper batteries and increasing availability of fast charging. Maybe for specialised vehicles? On-site construction, for example; would be awkward to try to get a digger to a fast charger twice a day but you could bring in H2 trucks.

Aircraft - H2 powered aircraft can land light like conventional ones. The explosion risk is a concern though. It took hours for the fire on the JAL aircraft to be put out a few days ago; imagine if instead of relatively tame kerosene, it had been full of high-pressure hydrogen tanks?

And of course that's a general issue. If the thought of a lithium battery fire worries you, the thought of a hydrogen tank fire should terrify you.

I agree - there are those who see hydrogen is a complete replacement for batteries and a solution to infrastructure challenges related to recharging of batteries, and while there are some use cases where it makes sense it certainly is not an easy replacement for batteries in many circumstances. Static storage in places where space is available and risk of explosion is low (BMW's solid hydrogen combustion test vehicle is not allowed to be stored indoors because it has to vent hydrogen) and where infrastructure to store can be established and maintained safely could work - but given what is in place today I wouldn't count on hydrogen bottles or tanks being any less of a dodgy and risky setup than people assembling their own batteries for home storage.
