Hi all, I am part of a team of students who are on a Product Development and Technology Integration Degree in Denmark. We are developing a greenhouse heat-sink concept and intend to do some prototype testing to determine how efficient such a system will be. We are also developing this as an Open Source product so will share all findings with everyone. At this stage we have built a small greenhouse 2.6m(8.5ft)*0.8m(2.62ft)*1.5m(4.9ft), this will be partitioned so that one side will be a control providing baseline data and the other side will have a heat-sink fitted. We have a several dataloggers with temperature sensors to monitor each greenhouse and the ambient temperature, then we can collate the data over several weeks or more to see how effective the heat-sink system is. We also have a materials testing box to test the thermal conductivity, thermal mass and air flow through each material type. Our aim is to make the entire system Open Source, we also have smaller key goals: · Extended growing season and frost protection for your greenhouse · Keep the cost as low as possible · Easy installation and accessibility of parts · All plans, work instructions, technical documents, electronic design and software will be freely available · Low power system running from Solar and battery back-up · Eco-Friendly by using recyclable materials as much as possible We have devised a very simply questionnaire which will take no more than 1 minute of your time, the questionnaire is designed to aid us in a 'House of Quality' study which determines which factors are most important to the user. The idea is to determine which criteria are most important to you and then place them in an order of importance. Google Forms House of Quality Questionnaire An idea of what the finished product may look like Thank you very much for your time, we are interested in all comments good or bad. Regards, Ant
Hi antscran---I am interested in your project & would like to hear more as it progresses. Will you be posting on Gardenstew or will you have a link to get more info?
