MIT researchers and scientists, along with Matter Design and CEMEX Global R&D present to us this compelling video. The largest of the blocks weighs 3,900 pounds, but the group easily showcases the ease to which they can be made into single and double story structures.
This same idea can be implemented in areas prone to flooding, as well, and might have huge global impacts in areas where a quick and concise community effort is needed to stem the flow of rising flood waters.
Pretty cool! :) -Fritz
