It wouldn't (just) be convection, but it would be easy to have a spinner over the top case fan on a PC... though going the other direction, convection off a fanless PC (I have a little Zotac) might be enough to spin a very light spinner (mylar might work, though to get a pivot without friction won't be easy).
Why would they be in luck? Did you read the article? Just because the efficiency floor is eliminated doesn’t mean production would or even could restart.
Looks like they were only (generally) outlawed for sale in 2023. Though some states were ahead of that.
They last a long time, though, and I imagine a lot of people are still using their existing bulbs. I can't imagine doing that in CA, where our electricity is expensive, but if you're paying 6c/kWh, I suppose, may as well?
A generation of under investment in energy production will create all kinds of government backed environmental propaganda. Incandescent bulbs = bad. Fossil fueled AI data centers = economy.
If there was a true environmental motivation for reducing our electricity usage, our bills wouldn't be 60% network charges, they would be 100% usage based charges.
I quite like these more - mainly because they could be added onto a lamp that puts off heat, and be kind of a perpetual decoration with subtle motion.
I love your “dad turbine” design, and the flying wing has some magical quality to it.
Thank you so much for sharing!
We used to do that as children as well: a spiral cutted out of paper on top of a long skewer stuck into a potato. Felt like perpetual motion somehow.
It works if you put it on top of a radiator btw.

Some lampshades call for a point source which LEDs struggle to replicate.
