The White steamer'designers developed advances which are more advanced than many present systems in general use. They could be drivable in minutes and many of the vital sub systems were automatic.
If you want to understand what a genius/forward thinker White really was...Jay Leno's garage show on you tube has at least two programs on his White steamer and its advanced systems. One issue had White's granddaughter who speaks about the man while Leno relates how he asked if it were possible for a steam system to be able to do several things. The present "steam experts" told him no...whereupon he simply showed them his White steamer....very embarrased "experts"
