  • This has me insanely curious as to where these are common and what are their emissions laws. Time for a trip down a rabbit hole.

    I looked into getting one of these or converting my own car to be gasoline and methane about 15 or 20 years ago. Here’s what I learned during that time. I don’t know if any of this legal information is out-of-date now. During the really early days of bi-fuel cars, homebrew cars were very bad polluters because they’d skip the emmisions systems altogether. This changed when the law was put in place requiring catalytic converters on all cars that burned gasoline.

    The challenge then with a bi-fuel car was you needed to build an emissions system that is compatible with two entire different fuels, with different combustion products. That is not a small challenge. This is fine for the gasoline side, however, there isn’t really a catalytic converter for methane because the exhaust gasses were actually cleaner than exhaust from a gasoline engine even after passing through the catalytic converter. So there was no market to create a cheap methane catalytic converter because it would have been nearly useless. The law didn’t care though and there was no exception for bi-fuel cars.

    There WAS an exception in the law for methane only cars, which is why you could actually buy methane (CNG) cars from major manufacturers like the Honda Civic GX:

    If you wanted to buy a used one of these, you can still find them and fill your CNG tank from your home’s natural gas line.

  • I would see it being similar to having 2 gas tanks in a car where one is for a high octane fuel and the other for a low performance fuel like ethanol.

    And these exist completely separate to EVs. They’re called bi-fuel vehichles.

    “How Do Bi-fuel Propane Vehicles Work? Bi-fuel propane vehicles typically use a spark-ignited internal combustion engine. A bi-fuel propane vehicle can use either gasoline or propane in the same internal combustion engine. Both fuels are stored on board and the driver can switch between the fuels. The vehicle is equipped with fuel tanks, fuel injection systems, and fuel lines for both fuels” source

    They aren’t common in the USA because of they way emissions laws were written which made it uneconomical in many cases for auto makers.

    There isn’t the same challenge in EVs, especially where we’re talking the “fuel” is just electricity which is common to both chemistry batteries. I see no challenge for EVs.








  • At least to me the use of memory palaces actually precludes the use of the stored information at the conceptual level.

    For me the usefulness of memorized information is the concepts it links to elsewhere in memory. Memory palaces replace these conceptual links with the “physical” link to the location in the memory palace reducing the information’s actual usefulness. So what is produced in my mind is a linear list I can recite, but those words have no meaning conceptually.

    For me, memory palaces work great at a party trick, but information is useful to me in conceptual form with its many links to other existing concepts I have, not as a rote list.







  • Nintendo is one of the worst and most unethical companies on the planet. Would be nice if there was a community where people could share their hatred over Nintendo. The 4 horsemen of the apocalypse are basically HP, Apple, Nintendo and Nestlé. Fuck all shitty corporations but fuck those 4 in particular.

    I agree with you on Nestlé, but HP, Apple, and Nintendo don’t even make the top 50 “worst and most unethical companies on the planet”. You need put in companies like Union Carbide India Limited responsible for the Bhopal disaster, the big tobacco companies, a whole bunch of defense contractors, some other agribusinesses, and a bunch of banks.
