Does liquid solar pool blanket work?

A liquid solar pool blanket, also known as a solar pool cover, is a thin layer of polyethylene or polypropylene that is placed on the surface of a swimming pool to reduce evaporation. It works by trapping the sun's heat in the water, which can increase the pool's temperature by up to 15 degrees Fahrenheit. Liquid solar pool blankets also reduce energy consumption by up to 75% by preventing the heat from escaping from the pool.

They are designed to sit on top of the water's surface and act as a physical barrier between the water and the air, preventing evaporation and heat loss. They can be made of various materials, including polyethylene or polypropylene, and are typically clear or blue to allow sunlight to pass through.

While not as efficient as a traditional solar blanket, liquid solar pool blankets do offer some advantages. They are easy to install and use and do not require any special equipment or maintenance. They can also be used on pools of any size or shape and can be removed easily for swimming or other activities.
