The solutions it brings to society are as follows:
1. Energy saving and emission reduction: The head-mounted solar fan is powered by solar energy and does not require solar energy. the use of batteries or power supplies, making full use of solar energy, has greatly reduced dependence on traditional energy and reduced carbon dioxide emissions, playing the role of energy saving and reducing emissions.
2. Portable Design: The head-mounted solar fan is easy to carry and can be used anytime and anywhere without power constraints. It is an essential tool for outdoor travel, sports, camping and other activities.
3. Environmental protection and health: The head-mounted solar fan only uses solar energy and does not produce any harmful substances. Healso has no electromagnetic radiation and is very environmentally friendly and healthy.
4. Improve work efficiency: Head-mounted solar fans can provide a cool environment for workers, making their work more efficient.
There is no point in boiling water to burn it. It's solar energy, not thermal energy.
If it's light energy, you can use lights to illuminate it.
Solar Cells You need a light over 1,000 lumens to get the driving voltage, or you can find a hundred watt bulb that can still be used for a bit.
Light energy refers to the presence of light. In fact, it works on the same principle as solar energy, except that its photosensitivity conversion rate is higher and its light requirements are lower. Inexpensive products with s-cellsolars on hats like yours will never be used. Light-powered watches, priced above 3,000 yuan, use this type of photosensitive cells, but they can only operate the watch. I can't blow the fan.
