I don’t think this analogy works. The solar input works like Diesel or Gasoline in different temperature. It’s pretty unreasonable to assume the consumer knows when depending on temperature unless the explicitly state in the manual (I’m willing to bet good money majority of the people in US have never read their car manual either)
- saghm 1y agoAgreed. No one needs to change which type of gas they use because it happens to be a warm sunny day.
- dotancohen 1y agoIn the Corvette community, using a higher octane fuel on hotter days is well known to prevent ping.
- jfengel 1y agoI'm surprised the Vette doesn't call for high octane all the time. It's common for high compression engines.
- dotancohen 1y agoThe knock sensor on LT1 and later engines allows one to get away with lower octane fuel for day to day driving.
- myself248 1y agoStraight Vegetable Oil (SVO) diesel conversions do. It'll gel at low temperatures, so they blend or switch to a separate tank of regular (or bio) diesel while the engine is cold, wait until it generates enough heat, circulate that heat along the SVO lines and into the tank, then switch over. Then switch back a few minutes before shutdown so the lines are full of regular diesel for the next cold start.
- rcxdude 1y agoBecause they run their engines well within the margins of their design. If you were running at the edge of the envelope you would find that the temperature does matter.
- happosai 1y agoTrue for gas not for diesel. You have to switch to winter- or arctic diesel if the temperature goes below -20c.
- bryanlarsen 1y agoGasoline is also blended differently for summer or winter. It's not as crucial as for diesel, but it does make a significant difference.
- throw-qqqqq 1y agoYeah car analogies suck. Diesel is blended differently for winter and summer in many countries. See this for instance https://www.crownoil.co.uk/guides/winter-blend-vs-summer-blend-diesel-guide/ https://www.crownoil.co.uk/guides/winter-blend-vs-summer-ble... Around the skiing season, many automotive magazines will remind diesel drivers to buy “winter diesel” or use additives if e.g. driving up to the Alps or similar cold places. It’s not so black and white :)
- Jgrubb 1y agoI love a good analogy. This is not a good analogy.
- jfengel 1y agoI'm not sure I know what a good analogy looks like. If the two things are identical, then the analogy is uninformative. If they're at all different, you will zero in on the differences rather than the similarities. Sometimes they can be ok pedagogical tools, but they're easily misused as tools of persuasion.
- jama211 1y agoYou’re not supposed to zero in on the ways in which an analogy doesn’t apply. You’re simply supposed to read the analogy in order to see what it’s attempting to _highlight_ about the scenario. This is a common pet peeve of mine, people not understanding how analogies are supposed to work and getting distracted by the differences. They’re supposed to work like a light filter placed over a lens, something will be highlighted and focus on that, don’t focus on the fact that “but all the colours are different now!”, the only purpose of using the light filter was to highlight a specific part of the image, the fact that it also coloured everything wrong temporarily is supposed to be ignored. You know, just to use an analogy to explain analogies. Gotta be as meta as possible.
- m463 1y agoa better fuel analogy would be to run e85 in a non flex-fuel car. (certain fuel systems components will be degraded by high ethanol gasoline)
