Cleaner Cycling

Here's something cool that I found while looking for green household items and gift ideas.
Gaiam's handmade vegetable soap is made with bike power! The unique invention pairs a bicycle power train with a soap-mixing vat allowing the soap-makers to pedal their way through every batch without electricity, synthetic scents or chemical hardeners. The soap is then cured for two months.
I wonder how many soap-makers and how many shifts of cyclists it takes to make a vat of soap.
