The system is running great, and our road tests are going well too. The wilskills van has been getting 33% better fuel mileage than our previous van (24mpg), and it is running on 95% biodiesel now (we just haven't run all of the diesel out of it yet).
Our soap is now for sale as well. A 16oz bottle is $4, and it is $6/gal (if you bring in your own container). Refills in the 16oz containers are $2ea. It can be used as a hand soap, laundry detergent, car wash, and shampoo. Contact firstname.lastname@example.org to purchase the soap.
