You and a friend walk into a potter's studio, or a shop that sells handmade goods. You gravitate to the beautifully crafted porcelain mug... it is quiet just like you like your mornings. It's light green celadon color is deliciously soft looking, and has a translucent quality about it. You pick it up... oh so comfortable. You look at the price, and you put it back down, and say to yourself, I can't spend $45 on a mug.

As a potter I use quite a bit of electricity to fire my kilns, and that bothers me.  I've always wished I could fire my kilns from the power of the sun using photovoltaics... but thought it was impossible since a kiln fires for about 15 hours using a great deal of electricity during that time period.
