    Hydrogen generation use and storage.

    or… just buy a base model 3. less cost at purchase than a bmw, audi, mercedez, lexus- about the same price as a new top end toyota suv. to match the cost per mile of operation home charging my model 3- your fuel source would need to be about 35 cents a gallon, assuming your car gets 35mpg. of...

    Hydrogen generation use and storage.

    h2 is about $5 a gallon. that’s the only part of the subject i’m interested in. there is the argument… that it would “get cheaper” if there was better h2 infrastructure, better h2O to h2 conversion tech… blah blah… etc. steam refraction of methane is the cheapest current method, of which, the...

    Boxer Diesel Weight

    there is a guy who put one of these in a 2-seater 'pusher' style aircraft, looks just like the LH-10. here's the specs he emailed to me: 311 Lbs., flight ready 150hp, stock. he is limited to that power level because of his shaft drive extension. i think it has a couple CV joints in it. 4.2...
