Hyundai rolls out 27 heavy-duty hydrogen trucks in Germany
Electric and Hydrogen trucks today struggle because <i>a truck needs a huge amount of energy to go somewhere</i>.<p>If that energy could be reduced, the problem would be far easier.<p>Here is a free idea for anyone working on this problem:<p>Make it more aerodynamic.  EU trucks today have flat fronts and flat back.  They&#x27;re super aero-inefficient.  US is better but not much.   The flat front and back are primarily to meet maximum length regulations, which are to allow them to navigate small streets.    Bypass all this by having an <i>inflatable</i> front and back that auto-inflate to make a pointed front and back when going over 40 mph on a straight road.   Use the same kind of construction as a SUP-paddleboard - ie. 15 psi air and thousands of cords for shape.   When the truck slows down, have the whole lot deflate to leave a flat front&#x2F;back.<p>This will ~halve energy requirements for long distance trucking, which, considering fuel&#x2F;energy is ~30% of the cost of shipping goods, is a massive financial win, as well as being good for the environment!<p>The main barriers will be regulatory.  You&#x27;ll have to persuade lots of government agencies to let you run trials of such things on the road.  Trucks have pretty strict regulations, and you can bet &#x27;stick a massive inflatable on the front&#x27; is going to mean you can&#x27;t meet some of them, so will need exceptions to those regulations.   That in turn will mean your truck can only drive in some states or regions, which will reduce its utility.
