This dome-like device will not waste a single volt or a cent.
The Egloo works by concentrating the heat gathered from candles placed inside a terracotta dome. It radiates warmth even after the flames have gone out. And this will only cost you 10 cents a day.
The gadget was developed by Marco Zagaria, a student at the Academy of Fine Arts in Rome, and successfully funded through Indiegogo.
According to the company behind it:
Egloo is composed by four elements: the base, the grill and the two domes. The base offers a space for the positioning of the candles that, once you light them up, will warm the domes up. There is a metal grill placed on the base, serving as a support for the domes. It makes a space to let the air in, necessary for the combustion of the candles.
For the well-functioning of the Egloo only four candles are needed. With an average duration of five hours they are enough to warm up a 20mq environment. The thinner dome, placed centrally on the base, stores a high rate of heat, that is conveyed to the external dome; the dome’s air intake facilitate the outgoing of the warm air stored between the covers, allowing thermal exchange with the environment.
