July 4th tour cancelled
The public tour on June 6th was fully booked almost 3 weeks ahead. Not so with our July 4th tour with no bookings as of today…very strange. Attendance at tours is always hard to predict…possibly something to do with the long weekend (but this hasn’t been the case in the past). Anyways, we have decided to take the day off and go kayaking so are going to cancel the tour. We have not been kayaking since our honeymoon over 5 years ago. It time for us to take a day off, pack a picnic and go paddling. Next public tour is August 8th. Booking has begun for this tour and since the Harrowsmith magazine will finally be out this tour is sure to fill up. See tour link on our blog for details.
Anyone have a 100% neoprene sprayskirt to sell. Needs to firmly attach Ann to her solstice kayak…although she has been quite moody lately and I may just drown her.
June has been a very busy month.
Gord has put in long hours researching equipment, reading manuals, installing sensors, setting up dedicated laptops, installing dataloggers, setting up software, and exploring research options. We would like to thank Christina Goodvin (mechanical engineer) for all her engineering help through this process, especially with the solar thermal side of the research. Check out this link to see some data and graphs. Hobolink
The KD2Pro Thermal Properties Analyzer is also giving some good solid data for the mass wall system. R-Value for the pumice cob wall is coming in at 0.93 per inch or for our 22 inch walls this means R-20.43 with a standard deviation of 0.013. This data came from 27 tests of one drilled hole. Now we need to do this 24 more times to make sure that the testing is bullet proof and statistically significant. For the first time in our post university lives our statistics courses are proving useful.
Let the experimentation begin. We are going to make up all kinds of new cob/plaster samples and do the thermal properties testing on them. Way too much fun for us geeky energy nerds.
All of this is keeping us quite busy as we digest all the goings on in the world. Here are a few links we found interesting these past couple of months.
