Fair enough, but that's not a replacement for 100LL since not all engines can use it. It's gotta be a pretty large FBO to have enough market to pay for setting up a distribution for UL94 in addition to 100 octane gas. Like, there

A post further down says that the first unleaded replacement for 100LL was actually just approved.

This is awesome. However, since it appears every certified airplane needs an STC to be able to use it, it doesn't seem likely that I'll be able to use it in our experimental aircraft any time soon. I can't imagine that our sm

Most planes don't need leaded gas. Jet-A / Diesel etc can also be used in planes. And yes, I understand small, old GA planes may be impacted, but this has been on the radar for decades now. This comment makes me think you don&#x

airplanes can gradually transition Except they can't, since there is no approved alternative. The other problem is that even planes that can run unleaded gas often don't, because it's not available at the airport. Avgas is

For the purpose of the climate crisis, we should talk about "carbon neutral" instead of "sustainable". It's both more clearly defined and more relevant to the current challenge.

Admittedly I'm not super familiar with this, but my impression is different. E.g. https://www.faa.gov/nextgen/programs/adsb/faq/ Why is the FAA transitioning away from radar and towards ADS-B techn

What I don't understand is how this is supposed to work when the point of using the more precise GPS-based ADS-B positional reporting is for controllers to be able to pack airplanes closer together. If they do this, there will literall

Yeah, the CNG ships seem a lot sketchier than an oil tanker.

With almost no exceptions, pilots have exactly zero say in what fuel to use. Airplanes are certified to use certain fuels and that's what you have to use. At this point there is no generally approved unleaded replacement for 100-octane

It doesn't mean that innovation is to the benefit of the user, though, does it? Maybe all the innovation is in anti-piracy technology?

Isn't it sort of obvious that practically every product developed for profit is done for the benefit of the organization doing it? "The needs of the user" is just one factor for satisfying the primary incentive, which is maki

It seems to me that the state can mandate vaccination if they determine that the advantages outweigh the disadvantages, full well knowing that there may be (probably will be, in fact) some rare side effects. How is this different than the s

Cases have been skyrocketing in Hawaii over the last month, though, especially on the outlying islands. Before July, the highest daily case count the Big Island had ever had was ~30. Now the 7-day average is 125, or 60/100k. Given the

It is _impossible_ to "knock" something from LEO to GEO. You can kick it to raise the apogee to GEO altitude, but the perigee will still be LEO. To change between two circular orbits, you need at least two impulses.

The orbital decay time depends on the ballistic coefficient of the body. This scales as mass/area, so is lower for small objects, meaning they decay faster. If the decay time for a Starlink satellite is a couple years, fragments from a

Antisat weapons aren't exactly simple, either, though. It's only been successfully done a few times. Intercepting something at orbital velocity isn't trivial (unless you have the capability to actually launch something into a

Isn't giving your credentials to a third party also a violation of the terms of service with your bank? It seems, at the very least, the bank will just tell you "too bad" if there's a breach and someone drains your bank

If you change your bank credentials, at least your current data is safe. You mean how to delete the data they scraped?

I don't think that's true. No matter how much you emit, you can still end up with more money if you emit less.

It seems a strategy that might work is pairing the carbon tax with a universal refundable tax credit such that it's revenue-neutral. That way people can pocket the difference if they want to use less carbon.

According to these guys, industrial process heat accounts for larger emissions than electricity and transportation: https://www.absolicon.com/ The nice thing is that it's easy to make heat with higher efficiency than g

The big unknown to me here is the impact of the interconnects. It's obvious that the intermittency problem gets smaller with better transmission infrastructure. What I can't recall seeing is actual studies of how much transmission

Given that you could probably build a Merlin out of solid gold and it would come in cheaper than an RS-25, that's not exactly saying much...

Why not just turn CO2 into a currency directly then? Your "proof of work" is the CO2 you sequestrated and can sell to someone else.

On short time scales, the oceans take up a lot of CO2 because there's an equilibrium with the atmosphere. However, increased acidification of the oceans is bad on its own, and this buffering hurts when you try to take the CO2 out of
