You might think that with a  Tesla Powerwall you have your home's renewable energy storage under control, but some very creative people have decided to build their own home storage system .

Using recycled laptops batteries can make their own home storage systems that cost less than the commercial option of Tesla: they solve a problem and reduce electronic waste at the same time. They have shared their designs for free online so that others can also do so and benefit.

The air conditioning is a problem that many people around the world face, but those who live in poor or isolated areas do not always have access or can use modern air conditioners.

In Bangladesh, the inventor Ashis Paul changed the use of plastic bottles to design the Eco Cooler : an air conditioning system that does not require electric power for its operation. Your company has already installed them in some 25,000 homes.

Humans will probably always need affordable and sustainable housing. The Project of World's Advanced Saving Project is working to satisfy these needs with its BigDelta, a great printer that prints in 3D at an almost zero cost in clay and clay. It is inspired by the mud wasp , which builds its houses with this material.

The innovators of the 3D printing Emerging Objects  devised a cooling solution for the home called Cool Brick. The ceramic device only needs water to cool a house in a dry and hot climate, and its operation is based on evaporative cooling systems that were already used 2,500 years before Christ.

When you can open a tap so that the water comes out without problems, it is easy to assume that the water is clean. However, there are many people all over the world who lack access to drinking water. UNICEF and the  Water and Sanitation Program came together to take it to the people of Cambodia.

Its ceramic water filters, manufactured and distributed by Cambodians, contribute to decrease 50% in diarrheal diseases after use. Ceramic water purifiers cost around $ 7.50 to $ 9.50 per system, according to a report from both organizations, and replacement filters cost around $ 2.50 to $ 4.

Evaporative cooling is also used in India, it is used in an energy efficient cooling solution designed by Ant Studio for a DEKI Electronics factory. The installation consists of conical terracotta tubes, and when the water passes over them - once or twice a day - the evaporation helps to lower the air temperature.

Remember those "inventors" who design their own Powerwall systems? One of those "gurus", Jehu Garcia, went to work to try to fight the Puerto Rico electricity crisis after Hurricane Maria. He published a video on YouTube detailing his design for a solar generator that costs around $ 550, including the cost of a solar panel and light bulbs.
