400 horsepower. Weighs less than a person. The engineering is incredible. The Astron Aerospace H2 Starfire engine proves that hydrogen combustion can outperform traditional gas engines. The technology is here. But there is a catch: The price of the fuel. Right now, filling up a tank with hydrogen costs nearly $200. That kills the innovation before it even hits the road. You cannot have a mass-market revolution with luxury-market fuel prices. This is the problem NewHydrogen solves. While companie
