But what's your point? It's a news roundup video, with several separate things. Edit:So I guess you mean exactly 5 minutes? Not off to a good start, with the "a very low energy dense gas can, be extracted from a very high energy dense gas" sentence. The two are the highest energy density gases (which is good), and hydrogen is the higher...
By the way, what does rabbiter mean?
Lol, someone who 'rabbits'. More or less, like me.
Rabbiting is a term for saying lots and getting little information. There was a famous song about it long ago here by Chad and Dave. But I'm rabbiting again

Well, rabbit as verb only meant run away to me. And even that I barely heard used. (probably first time was in the Avengers movie. ) So it took some effort to figure.
To me it's more annoying that he does voices, and says nonsensical things, like the sentence I quoted.
As for natural gas reforming. I wonder if anyone actually thought it was clean. I think it's definitely a huge waste to convert to CO2, compared to using it methane directly.
That would entail a significant weight increase. From 160 hp to 500.
Yes and it doesn't sound like they intend to do anything to reduce the weight of the ICE in line with its reduced power output.

From Mr Baretzky
However, he was less sold on hybrids. “I used to illustrate it like this. I’d put a little glass of water on the table, maybe 3cm of water, and point out this is the amount of fuel that has the same energy as the complete hybrid system. It’s ridiculous. 8MJ was the most powerful system, whereas one litre of fuel has around 40 MJ. But you are carrying along all of the complicated system as well.”
All true but it kinda misses the whole point. The hybrid system provides a two-way storage capability.
If you could build a system where - on application of the brakes, the exhaust gases were converted back to fuel and returned to the tank, you wouldn't need the hybrid system.

Although on a circuit racer, it's hard to beat converting braking forces into heat. Friction brakes (10kg?) plus fuel not saved (50kg?) will be lighter than the additional motor and battery. Off throttle fuel savings, if so needed, could be resolved with a stop start system, clutches, engine braking without fuel, etc. We could even reduce brake particulates with a jake brake. And reduced tire particulates from running a lighter car.

Just as a small aside about that, the LMP1 cars at least harvest the front wheels where 70% roughly of the energy is

Makes me think there must be engineers out there that scoff at the idea of braking through a flexible driveshaft, at this echelon of motorsport. The solution less appealing still: hub motors.
