With the voice synthesizer on my Mac "kettle of fish" and "kettle of ghoti"
sound exactly the same. George Bernard Shaw hated English spelling and said
that if you used the same rules of pronunciation and spelling that are used
in the words tough, women, and nation then the word "Fish" should be
spelled as "Ghoti". I guess the good people at Apple remembered Shaw.

If it can't do better than vanilla photovoltaics one can't help but ask if
putting an object larger than a supertanker into geosynchronous orbit is
really worth the gargantuan cost.

I can see that 3am would be a time of low demand, but this would be around
noon.

This problem like all problems is solvable, but it's going to take even
more money and we're already talking about astronomical sums. If we can't
get fusion to work I say fission Thorium reactors are a better long term
solution.
