Ideas:

- Flat plexiglass enclosure with insulation around tubes, calculate volume of tubes and use spreadsheet to estimate flow ratios and standing water time.  Allow whiteboarding to be done on enclosure.

- "cups brewed" counter, digital screen for flow, temp, watt-hour counters

- pull heater and connect more powerful kettle heater, use with large resivour for high "peak times" capacity

- solenoid connection fitted to kitchen sink, detects and fills low room temp res.

A system with a large "at temp" and "room temp" res's could be used to build a scaled up dispenser for coffee pots.  Push button, 4-8 cups out, auto filling feeder tank, insulated preheating tank, popping off fresh pots and dirty filters.

Or scale it down, reduce the sizes of tubes between tanks, change dispensing settings to run on continuous flow on/off switch.  Now it's a handheld hot water tap with a pushbutton interface, that can hold a kcup and dispense into a travel mug on the road.  Use a cheap drill as the new enclosure base?  Adjustable settings thru menu interface?

Excited to see project logs
