I'm excited for the new hydrogen engine that Toyota is developing. It solves the oil and polution problem and it's still the same good old combustion engine we are used to.,(reply>), they are building a hydrgon COMBUSTION engine? ok interesting. i only knew of hydrogen fuel cell electric cars. would be interesting to see a comparison of these two for efficiency.<br><br>but then's the question: where do you get your hydrogen from? :),(reply>), @Golag Is watching you Yeah, the solution is building more trains.<br>too bad Warren Buffett will never electrify his lines.,(reply>), Im sorry to say but I don't think Hydrogen is going to work out either, it's not as clean as they say it is.<br><br>Best solution would be a combination of new car engines and sadly building more trains and driving less cars in general.
