#Status as of September, 2025

We 3D printed a pot without heat transfer fins in the 100ml size. Using the a heat gun strapped
to a pipe, we were able to boil water efficiently. This is not a scientific test; it is prelude
to A-B testing. Nonetheless one must sometimes "play" to design the next step.

We attempted first to use a dryer hose, and that was a complete failure; the heat gun was so hot that
it discolored the inside of the dryer hose. It is clear that a great deal of heat was being lost through
the hose, as the discoloration fades of about 3 feet.

By the way, this small pot (we use 100ml standard test size) boils VERY quickly when put over a natural gas
burner. We are learning that the temperature of the heating gas is extremely important.

# Volunteer Opportunities

This project is still active, and the team is looking for additional volunteers with varied experience. Currently, the skillsets and experience that are needed include backgrounds in:

* Heat engineering
* Machining/making/3D printing
* Solid modeling/design

Alternatively, if you are new to the technical field but have interest in:

* Performing rigorous experiments, or
* Managing practical finances.

There is also a place for you on the team. If interested in joining the Ecopot or projects like it, reach out to Inventor Coach [Robert L. Read](read.robert@gmail.com) or Volunteer Coordinator [Miriam Castillo](https://www.linkedin.com/in/cstllgtrrz/). Ultimately, our mission is to further the reach of open-source medical engineering, and invent in the public, for the public. Check out our [Volunteer Page](https://www.pubinv.org/volunteer/) to learn more.
