🌞 Revolutionary Radiometer: TEDCO 01800 Sheds Light on Solar Energy Review

This product just doesn't work AT ALL. Just received it (looks like it's filled with all the skills and intelligence of a wounded llama). I put it in my yard at 3pm on a sunny September afternoon in Texas and it spins? no I have a video - it's impressive how it doesn't work. I think that under these conditions even the worst radiometer will rotate a little. But this one doesn't spin at all. Like 0 rpm. I checked to make sure it wasn't pinched or stuck to the glass. I made it spin by gently…

I was very pleased with the look of this device and placed it by the window of my office where it happily spun whenever sunlight fell on it for hours every clear morning . I live in Southern California and we get a lot of clear mornings in the summer. Ordered on 2.6. At some point in the last week or two it stopped spinning. If I tap it or otherwise break the friction in the bearing, it spins hesitantly but slowly to a complete stop for a few minutes no matter how much sunlight it gets. I don't

This delightful little device has been around for years. This is the approximate size and shape of a standard clear lightbulb with a base you can stand on. Inside, instead of a thread, is a small design of four square blades held on a sharp needle, which allows the device to rotate. The wings are painted white on one side and black on the other. Under the influence of direct sunlight, the slats rotate; The brighter and purer the light, the faster they spin. The physics of this is explained in…
