The personal value of the Biobot 20 probably depends on the amount of time you can dedicate to creating your own fuel and how much grease your household produces. Four liters of methanol required for refinement costs $3.50 and the sodium hydroxide runs for $0.50. The veggie oil is basically free, so a yield of 15 liters will end up totaling $1 a gallon. Better than current fuel prices and more environmentally friendly, the Biobot may help fuel the alternative transportation revolution.
