Why is it hard to harness the immense potential of a super conductor?? Is it the cost involved in manufacturing them or maintaining them?
I have read about superconductors as a part of my curriculum . But this amazing talk made things more clear about superconductors . My question is simple
1.Though this concept started 100 years ago, why have we not yet harnessed them?
2.What were the challenges faced , is it maintaining them in a particular temperature ??
3.Is the cost so high to maintain superconductors in a particularly low temperature or does money play a significant role in harnessing this energy?
I am sure there are physicists and scientists and other folks of science in TED community ,who can throw more light on this.
