DR Congo conflict: Mobile phones, coltan and the fighting

TL;DR


Summary:
- This article discusses the development of a new type of solar panel that can generate electricity at night by harnessing the temperature difference between the panel and the night sky.
- The technology, developed by researchers at the University of California, Davis, uses a thermoelectric generator to convert the heat radiated from the panel to the night sky into electricity.
- This innovation could potentially allow for continuous electricity generation from solar power, even during nighttime hours, expanding the applications and viability of solar energy as a renewable power source.
