3 unusual sources of alternative energy for home, office and recreation.

Little Sun – solar sunflower for domestic needs

Danish-Icelandic artist Olafur Eliasson has launched an unusual project called Little Sun, which combines creativity, technology and the social commitment of successful people to the underprivileged. We are talking about a small device in the form of a sunflower flower, which during the day is filled with energy from sunlight in order to bring illumination to the darkest corners of the planet in the evenings.

Anyone can donate money so that the Little Sun solar lamp appears in the life of a family from a Third World Country. Little Sun lamps allow children from slums and remote villages to devote evenings to study or reading, without which success in modern society is impossible.

Little Sun lamps can also be purchased for yourself, making them part of your own life. These devices can be used when going out into nature or to create an amazing evening atmosphere in open areas.

Green Heart – a sports field that converts calories burned into electricity

Many skeptics laugh at athletes, arguing that the forces expended by them during exercise can be used to generate electricity. The creators of the Green Heart sports ground followed this opinion and created the world’s first set of outdoor exercise equipment, each of which is a small power plant.

The first Green Heart sports ground appeared in November 2014 in London. The electricity that exercise enthusiasts generate on it can be used to charge mobile devices: smartphones or tablet computers.

The Green Heart site sends excess energy to local power grids.

Giraffe Street Lamp – power plant hidden in a swing for children

Paradoxically, even children can be forced to produce “green” energy. After all, they are never averse to doing something, somehow playing and having fun. That is why Dutch engineers have created an unusual swing called Giraffe Street Lamp, which uses children’s restlessness in the process of generating electricity.

The Giraffe Street Lamp swing generates energy when it is used for its intended purpose. Swinging in the seat, children or adults stimulate the dynamo built into this design. Of course, the electricity received is not enough for the full functioning of a private residential building. But the energy accumulated during the day of games is quite enough to operate a not very powerful street lamp for a couple of hours after dusk.
