Using the heat emitted by a laptop, storing it through efficient hardware to heat fluids.
The heat emitted from some laptops is so much that it could cause skin burns, this amount of energy that is being wasted each day could be collected and made of use. The coffee heater is a device that collects the heat emitted from a laptop from its outlet in a glass box with copper covering at the top which acts as the base of specific dimensions with certain arrangements so that minimum energy is wasted and maximum energy to be concentrated to the base to heat a container made of conducting material kept on it.
