The revamped model comes under the Glickenhaus Zero initiative. The nomenclature refers to the plan to build vehicles that generate zero emissions, and as we know, hydrogen fuel-cell powerplants produce no carbon-based byproducts. Hydrogen combustion makes water, and so Glickenhaus and company are calling the Hydrogen Boot the “first-ever zero-emissions Baja 1000″ race vehicle. Hydrogen is an interesting proposition for a Baja racer, because the power unit is extremely dense. SCG cites in its hilarious press release that hydrogen has a supremely high power density as compared to gasoline. This means that in applications like the undoubtedly heavy Boot race truck, hydrogen makes more sense than traditional alternative powertrains like batteries.
