Hopefully it will restore my energy and strength so I'll be able to post more often; and do more of what I want to do without falling.
I found this radiometer GIF on the internet.
I've had a radiometer for decades, fascinated by the way it spins in the light. It works with sunlight or an incandescent light bulb.
I finally decided to order a new one after mine stopped working.
Here's a photo from the internet that looks just like mine.
Sir William Crroke invented the radiometer.
Below are explanations about how it works.
It's not so simple!
When I saw this engine on Amazon I was fascinated. At first I was looking for a desk ornament but this was much better. It looks good and it's functional.
Here's a photo of my Stirling engine set on top of an insulated coffee mug. It works great and I had it running for 4 hours one time. That was the longest time for me.
I placed it on a dish filled with crushed ice instead of a coffee mug, it still worked! With ice cubes on top and a coffee cup at the bottom it goes faster.
This video explains how it works:

Evey used her balloon to hide her great-grandmother's face!
Never mind being half full or empty.
Maybe it's the wrong glass to start with.
Remember the best seller from decades ago The Power of Positive Thinking? I came across this video of some philosophical ideas that seem to go the other way, like "The Power of Negative Thinking".
I have a relative who always complains about how bad the world is. After a short while with him my mood begins to drop. That's why I try to limit my time with him. He looks at you as if you are crazy if you try to say anything positive about life. Sometimes I can make him change for a few seconds before he returns to his old self.
I made my daughter laugh when I told her that he belongs to a society of negative thinkers. I raise my eyebrows to give her a sign about what is coming next when we get together and he begins his negative discussions.
Anyway, this video seems to go for what is a negative view of life. What do you think?
