PARA 2 - On second thought, that can't be right. If for example it costs $1 to build a normal single today then half the cost is $.50. A NXT tandem using some parts in common but with an additional layer has to use more total parts so has to cost more, say 1.30. Knock off 35% for today's efficiency nr and you are left with $.75 which is not $.50 above. The tandem doubles power/efficiency but is not 50% cheaper than today's single sell.
