Firstly, homes will be environmental.During the day, the roof of our houses will be turned transparent so that the whole rooms can be bathed in sunlight. Solar energy will be collected in the energy storage space. They can be used for water heating, electricity using, and so on.Also we no longer need to use air-conditioners or heating equipment. Because the surface material of the houses can interact with the outdoor climate. Then the indoor temperature will be adjusted automatically through the material of the house inside. There will not be sweating or cold shivering any more.These two designs can effectively solve our energy crisis.
