A low- to medium-resolution printer that uses a type of coated paper that darkens when heat is applied to it. The paper is passed by a line of heating elements that burn dots onto the paper. This is ...

Engineers can now efficiently convert heat into electricity, creating a huge potential to reduce greenhouse effects by capturing exhaust heat and cutting down primary energy wastage. Dr Tony ...

Hong Kong University researchers have invented and patented a direct thermal charging cell (DTCC). The DTCC is a recapture device that turns low-grade heat (under 200°C) into electricity. Low-grade ...
