@BroDrillard @Paultron I'm thinking a float with a solenoid and a steam-kettle chamber. So the system always has water ready to dump into the steamer, but it doesn't load above peak (think on-counter Keurig type system). From there it's just dumping into the steam chamber which you could rig as undersized outlets on a metal container. You want more surface area and small amount of water so that it heats quickly. I think pre heating before it hits the steam chamber itself, possibly a double heater situation. I'm thinking like an instant-on faucet level water heater or something from a steam cleaner for commercial grade. Delivery would be the hardest part. Disorganized rambling here.
