Alumnus Dr. Donald R. Sadoway (EngSci 7T2, MSE MASc 7T3, PhD 7T7) is the John F. Elliot Professor of Materials Chemistry in the Department of Materials Science & Engineering at the Massachusetts Institute of Technology (MIT).

One of 2012 TIME Magazine’s 100 Most Influential People in the World, Dr. Sadoway is regarded as one of the world’s foremost experts in electrochemical materials engineering for renewable energy storage technologies. Sadoway’s spin-off company, Ambri Inc – established to commercialize his invention – is backed by notable supports like Bill Gates. This spring, he received an honorary degree from his Alma Mater in recognition of his significant contributions to the field and mentoring of countless great minds.

    Hello professor , George Bexis here i have looked at several of your seminars on youtube and my hats off to you and your dedication to solving energy issues we all have to deal with everyday. I am a cable repairman and have been repairing the copper for almost 15 years.
    As you already know bell canada manages a DC power grid to energized its phones , fiber stingers , remotes and so on. we use a battery system to generated Dc power to energize cables upto 10 15 kms but the average being about 1.2 km.
    Its a one way street we power up our DC grid with AC power simple but very costly concept. we have backup generators to supply batteries in case of blackouts . Now that our copper runs are being discarded for the fiber runs this copper is still in place until we get the majority of our customers cut over to fiber .
    I drew up a schematic of reversing the energy from individual homes on existing copper back to the frame at our central office which could possibly provide free energy to charge a large battery source you seem to be working on.
    Because all of our central offices are interconnected with old trunk cables 19 gauge up to 3000 pair copper we can push alot of power around to work on a renewable energy source. I would love to move forward and have direct contact with director of energy Bell Canada..
