The Sun’s energy contribution to the Earth is more than enough than what would be necessary to power the modern world. But there are two technological hurdles to our solar societies. On one hand, solar panels need to be more efficient. On the other, solar energy is intermittent and human demand is not, which means that we need good batteries to store solar power when its available. But so far, our batteries aren’t so good.
Donald Sagoway and a group at MIT are currently working to fix the latter problem with liquid metal battery technology. Sagoway’s presentation is so impressive I couldn’t not share it. Can his team find the missing link to alternative energy?
