From Greg Borrowman
Although Don Gilmour’s invention of an electronically self-tuning piano has merit, I shudder to think of the amount of energy that would be wasted if it catches on (7 December, p 20). The idea of every one of the thousands of new pianos being sold consuming 500 to 600 watts of electricity every time they are played is abhorrent in these environmentally conscious times. For some pianists, their monthly power bill might well exceed the cost of having the piano tuned frequently enough to keep it in tune.
