@Stlaind - Usually the maximum energy (for the design) has been taken from the turbine exhaust. If there were worthwhile heat to remove, another turbine stage would be added.

@rleerm - I didn't even watch. Comments like yours saved me. :-)

@maxjtj31 - Both valves open for a bit. This was done in WWII by the Germans.

Is it legal to add rotating blades to the axle hubs? Death Race!

@Strait_Raider - And then there is the problem of sealing the hydrogen. That's a big problem in handling hydrogen. Single proton/electron atoms sneak through the smallest danged imperfections in seals.

@cherriberri8373 - We live in a reality where race rules dictate what happens. Physics don't limit the car acceleration and top speeds. Rules do. Accept that or be disappointed. The premise of the video is a big "what if" there were no rules. People clicking the link expect physics to be the limiter. It's not. The video immediately establishes new rules. So, the video is a self-contradiction and thus a disappointment for many.

@infinitesimotel - Name one game that doesn't have rules. There would no longer be a game. It would be life in anarchy.

@Idiomatick - Sooner or later someone else would you take you on with the same strategy and your season would end in a big bang.

Right? 300 lbs of force on the brakes? WTF? Well, at least that will lighten the load on the driver's groin belts, so there is motivation to push on those pedals!

That teaching assumes that attempts to turn the car have the same tire performance limits as the attempts to slow it down. In other words, it assumes all else is equal. As the video points out, all else is not equal. Turning while braking does add the need for some lateral frictional force, but braking while turning adds the ability to deliver more force through the front tires (and less through the rear) by adding downforce on the front and outside tires. So, the relationship of all the forces is not so cut-and-dry.

@pinkace - Who says it is better to do only one at a time? I didn't. The video didn't. Why? If do one at a time, you get each one for less distance/time for each function and that maybe a suboptimal choice. An braking action while turning with diminishing radius is probably optimal, but will require variable braking and turning. Braking before the turn makes you take longer to get to the turn and you will get through the turn slower as well. So, while braking during the turn might require a larger turn radius and thus longer distance to get through the turn, you will get there sooner and (apparently) out sooner. Believe the pros, unless you can beat them. Unless you've done numerical simulations on the matter and driven your solution in competition, don't assume your primitive separation of the two functions is optimal. The pros have their own experts AND experience.

The problem for that might become making a profitable and recurring race. A few highly-funded teams could drive out the others. Fewer race teams = less interest from fans = less revenue. Additionally, less revenue = smaller prize money. Smaller prize money = lower quality team effort = lower quality fan enjoyment = declining fan revenue.
