- Thermoelectric material converts differences in temperature directly to electrical voltage
- It is not the first, but previous ones have been derived from rare and sometimes toxic elements via costly synthesis procedures
- Researchers say their discovery could pave the way for low-cost, environmentally friendly electricity generation
Researchers say they produced the groundbreaking substance using commonly found materials and that it can be cheaply manufactured.
They believe the it could spark a revolution in eco-friendly power generation by taking waste heat from a range of common sources and converting it directly to electricity.
