Pumping water with no moving parts

Bill takes apart a coffee maker to show how hot water is pumped through it using a “bubble pump.” The use of this pump reflects an engineer’s choice to have only one heating element to lower the cost. We love these videos.

  1. love it, i may need to implement this in a future project

  2. Yes they move water with no parts!!! Oh yah the aquaduct did that, but for 100s of years we’ve had siphons and ways to auto siphon from diff levels of gravity have been achieved. What is cool is the engineers breaks on constraints and cost in design
