response to alternative fuel were ok but do you know indepth how much $ for solar, hydrogen duhh and extractin

…g? do you know how much you can trust hear-say? as a matter of fact, diesel engines were primarily to run out of vegetable oils, expensive and huge fields to grow unless in Brazil; costly hydrogen duhh to produce; need better batteries and better climate for solar;new oil fields to discover, don’t forget that China wants SUVs and the same standard of living as in USA, hope we don’t go to another war for remnants of petroleum…maybe for now the solution is to apply ALL of this concepts…and do your research…
