Edison said that "surprise is the seed of science". So I especially like exploration and research, especially like inventing some small things.
Today I'm going to invent a solar electric fan. Its color is purple and its shape is oval. Its accessories include: thermometer, fan, solar energy tester, wireless antenna, etc.
Although it has many accessories, it is only the size of a palm and is very convenient to carry. Its functions are: measuring solar energy with a solar energy tester and supplying power; Then use a thermometer and press a button, and the temperature will be measured. Sometimes, the clouds in the sky are difficult to measure, so a wireless antenna is installed to measure through the clouds. If the temperature is higher than 22 degrees, adjust the temperature below 22 degrees and let the small fan help blow out the cool air.
If the temperature is lower than 22 degrees, adjust the temperature to be higher than 22 degrees. Of course, instead of asking you to guess a few degrees, there is a small screen that will show this number. The solar electric fan also has a rope that can be hung around the neck. The biggest advantage of solar electric fans is that they don't waste batteries and are environmentally friendly!
Solar electric fans have many advantages and are easy to manufacture. Do you like them?
