Many of us enjoy a hot beverage in the morning, unfortunately after a few sips and trying to make it all the way to work with your beverage, it slowly cools off. Keeping your beverages hot or cold won’t be a problem anymore if you use the Attemper Stir-stick. This was created by an Indonesian industrial designer. Attemper uses the thermoelectric effect to convert electrical energy into a temperature gradient. Using nano-silicon as a material to decrease silicon’s thermal conductivity it also increases the conversion efficiency. Using just one single stir stick, you are able to produce hot and cold temperatures for your drinks. For those of you like myself that cant stand excessively hot beverages, you could take this stick and turn it counter-clockwise to cool off your drink. To get some heat, simply twist the stick head clockwise. Recharge this gadget when the light goes off. Pretty innovative design I think! I love it and I would definitely invest in something like this! Very cool invention.
