looking for the plans used in Portland Hestia Biogas precursor

Hestia seems to have gone out of business I guess ?  Any one know ?  Before they tried to amrket the pre-made units, they sold the plans for their backyard build.  Does anyone have a copy of these or know how to reach the Hestia people ?  It was built from bricks or cement blocks and had an EPDM cover that would expand and also provide the pressure for the gas, this was a home built design

Hi Debi, is this the one you are looking for?

Looks like they tried to raise funding a few years back - guessing it didn’t play out since the website is now for sale. Bummer!

Yes but there are plans somewhere for that unit

yes, they are out of business. Afaik for a long time. If there are plans somewhere... hmm. I think I put them up some time ago... https://www.biogascentral.net/sites/default/files/downloads/100-dollar-biogas-digester.pdf
