I view energy storage as the biggest road block to implementing sustainable alternative energies. I want to see this happen, so I'm thinking energy storage is what I should go into. I view it as very versatile, and also as a growing industry. I also think there are inevitable improvements being made, and that will be made. All of this stuff is good. The bad part comes from talking to technicians. I've talked to a few who worked in battery production and they all strongly disliked it due to dealing with nasty chemicals/pollutants. This, though, is common amongst most chemical engineering work I think. I'd also hope to get into battery research rather than purely production. So, input on a good energy storage field to enter?
