Dezeen's Emma Tucker takes a look at an innovative terracotta heater that stores and slowly emits heat without using any electricity.
The base of the device can hold up to four candles, which sit beneath its metal grill. Two domed covers with an exterior allow warm air to circulate up and into the space. Since it's able to store heat, the the device, dubbed the Egloo, radiates warmth even after the candles have gone out. The monthly cost of the portable, compact heater is about $3.
