It sounds funny, but soon mobile gadgets can be recharged from any flower. Home cactus, for example. In what way? With the device E-Kaia. This extraordinary invention introduced a team of scientists from Chile. This is also a battery charger, which uses as a power the conventional room or outdoor plants.
The device allows you to use the residual energy that is produced during photosynthesis. What allows you to restore a dead battery in about 1.5 hours. It seems science fiction, but the technology works properly. As a donor used single plant, although its dimensions are not specified.
The main thing – the system has virtually no competitors. Analogs significant efficiency do not differ. They need to 100 square meters of green space. E-Kaia satisfied with a single plant. It is enough to generate 5V and 600mA. It looks pretty promising. How works E-Kaia, no known, the developers kept technology secret, waiting for a patent on it.
