Interesting. Great idea. But I'm curious about a lot of elements of this campaign. What is the amount of reduction in CO2 emissions? Is this product "street legal?" Is there an affect on performance? What is the marketing plan – I don't necessarily see many people paying $60 every two months for a product when it doesn't actually do anything they would immediately notice. So is the plan then to get the product noticed and then get big auto on board to incorporate elements of it into cars?
