So, in my efforts of talking to everyone I can about this- in hopes that someone may have something helpful to say.... I was talking with this customer at work and he was telling me that he owns a business and that around town his semi-trucks are getting 3/5 MPG and that if there was an hho system for trucks he would pay big money for that.
Now my reaction was- I am way too new at this to be trying it on someone else's means of living! But my question here is, has anyone thought about making one for a large truck like that? Is it even possible?
