{News link in this Forum about germanium being used to treble the current handling capacity of transistors] (IBM research)or reduce the power needs for a given purpose.

I have a 41 year old battery radio in my bathroom.

The circuit board is huge with discrete germanium transistors, sausage sized resistors and capacitors. Long ago the epicyclic tuning dial suffered from perished rubber and is secured with BluTack. The oscillator transistor has been replaced and the battery is a stack of rechargeable AA cells.

In the intervening years the silicon transistor took over and I (at least) thought germanium old hat! Yes they were less wasteful with battery power than their successors. And now a hybrid seems to be in the offing. What next?
