I bought the drinking bird toy, and I want to get a better understanding of it, (https://en.wikipedia.org/wiki/Drinking_bird)
I understand the basic way it works and that it is a simple heat engine, but I can't seem to find any information that helps me answer the following
- I notice all these toys have the same sized glass bulb where the dichloromethane sits. What happens if you make the bulb larger so it holds more dichloromethane but keep the rest of the bird the same ?
- I find this simple heat engine pretty fascinating and I am trying to understand how it can be made more efficient, like if perhaps magnets could be added to help reduce friction instead of the toys normal metal piece to hold it up ?
- I can't find this answer anywhere I have looked but does increasing the size result in lower efficiency? I don't see anywhere any information on anyone playing with the dimensions for fun and trying to make it swing better?
Thanks for any help
