In this short clip the heat-up results of a very “quick and dirty” prototype setup of two different objects can be seen. The base materials were directly coated with our thermoelectric polymer, whereby the voltage was set to 220V. The heating power in this setup was about 30 kW/m². With this setup we were able to heat up the 6mm thick concrete to 100°C within 40 seconds. After reaching this temperature, the concrete stayed warm for more than 30 minutes. Just amazing.

We should really consider developing a vehicle coffee-maker with a sensor measuring driver mood and automatically proposing a hot beverage at the right moment! One more idea for our collection …
