Solar power, 24/7
You don’t need to be Captain Obvious to know that the biggest problem with solar power is that it doesn’t work as well on cloudy days or at night. Well, a group at MIT have possibly found a workaround. In short, the system builds up enough back-up energy over a few sunny days to cover one cloudy day.
Of course, there is still one snag with this set-up: it requires a trained specialist to fix it
when if it screws up. However, it’s definitely a step forward to widespread solar power.
