Why? They have more fuel on board now than with these pods. It's all about the container.
Can anyone equate how much CNG would be equal to the current 100kg gasoline by volume? Is it roughly 1:1?
It'snot about the volume of fuel, its about it being pressurized. That means that your regulation into engine becomes a weak point, and if there is a fire we will be putting track workers and drivers in a position where there is pressurized canisters of fuel.
Fuel cells are bladders in a rigid structure. They are essentially invincible. Even when torn from the vehicle only fuel in the outfeed hose is released on track. It self seals.
NOt just that, but storage. Remember Williams garage fire? What about an impact from a rolled car on something?
It just seems like once you introduce pressurized canisters (being put in hastily at a pit stop) your F1 car becoming a large exploding bomb is no longer zero.
