Should not be entered very often (once per hour let's say? max every 30 min).</div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;"><br></div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;">The hexayurt structure sounds really nice, I wonder
if anyone has experience with that concept and would be willing to help out - either theoretically with the design or practically, both the best.</div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;"><br></div><div><font size="2">I wonder Arjen if I understand correctly that the structure of the yurt should be doubled.

It looks like that the orga is not super excited about the idea of small sea of liquid nitrogen (probably Terminator 2 exposure in an early childhood) I wonder about the bottle of the pressed CO2 which you suggested mclien. If we insulate the
structure how much would we need for the initial cooling of hexayurt of 10 square meter floor projection and 2 m high (lets say in the middle) any ideas? Does someone knows some good hexayurt calculator, Arjen, Walter? I'm not sure what is the situation in the area with the used insulation material but I'm bit afraid that Dutch are bit to organized to leave such "mess" around. </font></div><div><font size="2"><br></font></div><div><font size="2">Anyone knows about used air-conditioning unit? Cheaper/free best ... How much could used air-con cost in Holland or Belgium/Germany? </font></div><div><font size="2"><br></font></div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;">Well I hope that I went over the major points. I will be present on the camp ground since it opens, so 23/24th of July, ready to start to work on this project. I should be in the area already around one week before (Amsterdam).
It would be great to have help from someone to make a proper build up proposal, I have never done hexayurt before so ...</div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;"><br></div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;">Sincerely from Jeju,</div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;"><br></div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;"><span style="font-size:10pt;">Frantisek Algoldor Apfelbeck</span></div></span></div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;"><br></div><div style="font-family: 'bookman old style', 'new york', times, serif; font-size: 10pt;">biotechnologist&kvasir and hacker</div><br><br><div style="font-family: 'bookman old style', 'new york', times, serif; font-size:
