Absolutely.^^^
But if the F1 guys were allowed under the rules to recover some of the spent exhaust gas heat (they recover the exhaust energy with turbos this year) and the spent radiant heat they would have even more power.

A turbocharger sounds like the obvious way to recover exhaust energy and I wonder why this system is better?

Turbo's really don't do much for economy. They allow you to retain economy (out of boost) and still have the option of having power (on boost). My F-150 gets fantastic mileage if I mostly stay out of the boost. But when I spool them up look out! Fuel gets used. It's fast though.
