MIT develops thermo-PV cell with 40% efficiency
Researchers at MIT have developed a heat engine that can convert heat to electricity with 40% efficiency. Unlike traditional heat engines – a common example is the internal combustion engine inside a car – this device doesn’t have any moving … Continue reading

The ‘could’ve, should’ve, would’ve’ of R&D
ISRO’s Moon rover, which will move around the lunar surface come September (if all goes well), will live and and die in a span of 14 days because that’s how long the lithium-ion cells it’s equipped with can survive the … Continue reading
