I have a couple of those new-fangled light bulbs with ribbon LEDs,

Impressive. They use very little power. I'm sure it wouldn't take much
for the technophobes in Brussels to think that the elements in a
toaster could be replaced by such a ribbon LED, thereby saving
megawatts across Europe.

No, no, np. The life of LEDs is too long that the manufacturers won't
stand for the lack of repeat sales. First you introduce energy saving
CFL toasters, then when people complain about the sickly colour and
lukewarm toast that won't melt butter you back-track a little to allow
eco-halogen toasters, only later do you introduce a series of 850nm,
940nm, 1050nm etc LED toasters and finally LASER toasters ...
