We always brought crap to eat on field trips, because it was a break from our usual routine. This woman's elevator doesn't go all the way to the top floor.
The real breakthrough would be direct Photocatalysis, the HolyGrail that has been eluding us since it was first described in 1967, known as the Honda/Fujisawa effect. UV light illuminating a Titania cathode connected externally to a platinum anode in water first hydrolyzed water. O2 at the titania electrode and H at the platinum electrode. This looks like self promotion of a more efficient electrolysis for ARPA-E funding.
They probably also killed the Ultrasound washer I saw being developed 15 years ago. Procter and Gamble probably payed the guy off. No soap just water and maybe an added fragrance of your choice.
