Usually, numbers over 100% mean that you are putting in less energy than is needed for the process. In this case, that would mean putting in a little over a quarter of the needed energy. That does not imply free energy or anything. The rest of the energy has to come from the environment.
A heat pump is another common example with efficiency numbers in the same ballpark. With a heat pump, the heat is being moved from outside to inside (or vice versa for air conditioning and refrigerators). In that case, it requires, for example, 1kW of electricity input to move 3.85kW of heat.
- kwhitefoot 5y agoEfficiency is still the wrong name. What you are describing is usually referred to a coefficient of performance, abbreviated to COP. See https://en.wikipedia.org/wiki/Coefficient_of_performance https://en.wikipedia.org/wiki/Coefficient_of_performance
- faceplanted 5y agoThe Deja vu sensation of this conversation happening almost identically 2 days ago (everything from wondering how >100% efficiency works, someone explaining it's from the environment, and then someone else explaining efficiency is inappropriate and COP exists) is kinda wild.
- adolph 5y agoNothing to worry about. Its people alpha-testing the Copilot internet commenting plugin.
- SamBam 5y agoCan't wait for all our text input boxes on the web to be GPT-3-enabled, and then all comments on HN and Reddit and Twitter will be just people accepting the defaults, and it will end up just being GPT-3 talking to itself, and we can all go back to doing something productive.
- adolph 5y agoPretty sure FB has several instances of itself with all the users played by GPT-3 trained on the users’ previous activities so they can monte carlo various changes, like pre-A|B testing or estimating impact of various new ad types or congressional testimonies.
- Scoundreller 5y agoReminds me of a post here where it was some neural network chat/excuse generator. Just two people back and forthing about why they couldn’t meet up. I lost it when one of the excuses was, 3 weeks later “oh, I can’t meet for lunch on July 29th, I have to go to my mother’s funeral”
- SamBam 5y agoAmy way you can link to that conversation? I tried to find it on Google.
- Scoundreller 5y agoI think the convo is different each time. You’d have to search here for the chat itself. It was 2-3 months Ago
