Moments after listening to the conclusion of Dean Fisher’s lecture on fracture critical design in class on Tuesday, I started to become slightly depressed and nervous about the future of the world we live in. We must make changes NOW, because there is no time to spare. Now, I understand that we as a society must develop a better outlook in order to salvage our planet for the generations that will precede us, but I was unaware of some of the facts that were presented during the lecture. If I’m not mistaken, Dean Fisher stated 50 percent of the world’s population will be wiped out within the next 50 years if we keep living our current ways. All types of changes, including political, ecological, environmental, and material, must be introduced to save the human species. This blog will focus on the material innovations of liquid metal batteries.
Donald Sadoway, a material chemistry professor at MIT, is in the process of developing liquid metal batteries in order to store mass amounts of energy for times of need. However, his ideas of smelting aluminum to create massive battery liquid seem a bit ambitious. If this innovation was to succeed, society would be able to produce electricity at an extremely low cost and without the harmful gas emissions. The liquid metal electrodes would be stable enough to provide electricity on a grid system for multiple blocks. These forms of innovations may be just what we need to clean our environment and save our planet. So whether our innovations involve just replacing a dryer with an outdoor clothesline to producing hybrid electric cars, changes must be made.
