Eco-environmental protection is a development model promoted by modern society. The toilet is a large water user and a large amount of water is lost from the inside every day. Lukasz Ekwinski has designed an eco-toilet for this, raising the stumbling door to hide the roof solar panels, and the inside of the toilet. The temperature can be finely adjusted. The shaded part is equipped with a metal cover to ensure the heat in the air. The indoor lighting is absorbed by the solar panel. The sunroof design not only can provide ventilation, but also can use natural light and toilet water to store rainwater.
