AI Thread Summary
Building a greenhouse in a windy area like North Scotland can benefit from a wind-powered heating element to maintain higher temperatures. While a simple heating element is efficient, using black materials for solar heating could be a cost-effective alternative. Concerns about temperature swings at night can be addressed by incorporating underground heat storage or using stone flooring tiles to retain heat. Additionally, large water troughs can serve as thermal mass to stabilize temperature fluctuations. These methods can enhance the growing season while balancing complexity and cost.

Hello. I'm planning on building a green house in my garden with a wind powered heating element to help sustain higher temperatures. I live in a windy area (North Sotland) so wind prevolance is no problem. Would an element be the best way to this or are there better methods of converting electricity to heat? Any help would be greatly appreciated!

A simple heating element is about as efficient as you can get, although why not use black material and go with a cheap solar approach? Would the day night temperature swings be a problem?
 
Thanks for the reply. Yeah, the idea of the wind turbine was to compesate for night temperatures and to give a longer growing season without wholy depending on solar energy. Maybe an underground heat store could also help out. But i suppose it perhaps unnecessarily adds to complexity and cost.

Stone flooring tiles might be another option. They'll heat up during the day and slowly release their heat overnight.
 
Some gardeners put a big water trough in their greenhouse for the same effect; providing a large thermal mass to even out day/night temperature fluctuations.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
