I wish I knew what you were talking about - but don't try to explain,
I'd

Interesting article in todays New Scientist suggest that further research
into tungsten filaments is showing that 50% efficiency may be possible -
as
opposed to 25% for fluorescents.

I have posted the article at

http://nanohelix.tripod.com/ns.jpg

I went to it eagerly.

I can't read it :-(

What's more, I can't convert it into a readable form :-((
