The Röshults Booster Grill is a charcoal grill where the glow bed is agitated by inaudible infrasound. Infrasound is sound with extremely low frequencies. A human being cannot hear those low frequencies, but still the infrasound can be very powerful. With infra-sound technology, we can control the movements of the molecules in the layers of charcoal. We push them to move faster, making the heat rise and the glow grow stronger. All within seconds.
