Yup. And LEDs just keep getting better, as do batteries and solar panels. With new photovoltaic technologies, we're starting to see some bargains in older-type solar panels, too. Harbor Freight even has some small ones under $30.

Another exciting idea was pioneered in Japan, where they've grown vegetables underground using sunlight piped in through fiberoptic bundles. I didn't think too much about this one until I saw a huge spool of fiberoptic cable for sale cheap at a salvage yard....

I believe in my heart there is a way to coax a glow from a crystal, but I don't know what it is.
