The commercial future of solar energy may have gotten a big boost. Researchers led by Professor Benoit Marsan at the University of Quebec at Montreal have solved two major problems that had been hampering the efficiency and affordability of creating solar cells. Marsan has patented an electrochemical cell that uses different materials from conventional solar cells–replacing platinum with cheaper cobalt sulphide and creating a new gel that is non-corrosive to boost energy output.
Are university safe spaces killing intellectual growth?
Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
