I’ve had this idea for a while. Looks like rch beat me to it.
-It uses similar tech to bathroom urinals, so the water is only on when you’re close to it, saving water.
-You’re free to step away and lather and the water will cut off, conserving it. You really only use the water for initial wetting and then rinsing.
-Also, this design will use the pressure of the water and the water running through the connector to recharge itself.
-The user can position the beam exactly where they want it to be.
-The beam probably wouldn’t be visible until the steam runs through it like in the spy movies. But it would be nice if it could leave a light on the floor where it hits in the beginning so that there’s and indication of where the beam is.
I didn’t do any form development, etc…it’s just to get the idea out and to practice with this new digital sketching stuff.
