1. The water in solar energy cannot be used for a long time, because the water quality is poor and there are many bacteria, so it needs to be drained and cannot be used for bathing or drink;
2. Water that stays in the water tank for a long time will generally have a temperature above 70 degrees. It will boil after more than 2 days in sunny summer weather. stay in the 60-70 degree range for a long time. This temperature zone will cause bacteria in the water to multiply rapidly;
3. Bathe with solar water that has not been used. used for a long time is not good for the skin. Long-term use of this bath water will cause skin diseases.

4. Water in water; The tank which remains stationary for a long time is easily contaminated by scale, bacteria present inair and other harmful substances, thereby forming stagnant water. Long-term exposure to stagnant water will cause varying degrees of damage to the human body.
In today's society, no one doubts the use of biochemical energy to replace chemical reactions to obtain electrical energy, because many reports abroad have made status of the development of bacterial batteries, including marine bacteria. This bacteria with its own energy production function was discovered by an American researcher in the Dead Sea and the Great Salt Lake. Its cells have a thin film composed of a purple-red protein called rhodopsin. natural energy converter. Electrical charges are created when approximately 10% of received sunlight is converted into chemicals. Later, scientists used this bacteria to create a small experimental solar bacterial battery andused to power channel lights, traffic lights and airport runway indicators. We see that allowing bacteria to provide energy to humans is no longer a legend, but has become a reality.
