Bio-Inferno

Imagine how much money you could save if you could heat your greenhouses with oil derived from sawdust. Great Lakes Greenhouse in Leamington, Ontario, tried it without much extra effort to convert its existing boilers, thanks to the resources and know-how of Dynamotive Energy Systems Corp., based in Vancouver, B.C. Great Lakes Greenhouse, a 1.2-million-square-foot operation that grows seedless cucumbers, ran a four-hour combustion test, burning 2 tons of Dynamotive’s BioOil, a product made from forest and agricultural wastes. The operation, which normally uses Bunker C oil (No. 6 fuel oil), was able to burn the BioOil in its own boilers. According to Andrew Kingston, president and CEO of Dynamotive, further testing will be conducted, but he says the result of the combustion test substituting BioOil for a fossil fuel was encouraging. “During the testing, Dynamotive’s BioOil demonstrated very good ignition properties, steady flame characteristics and a low emissions profile,” […]

Can You Afford Free Heat?

A whole lot of progress is happening in alternative fuels these days, all around this great country of ours. The number of growers who have gone from researching to actually installing biomass boilers keeps rising, and the savings are no doubt significant no matter the fuel used. However substantial these savings have been from burning corn, tires, oat pellets, beans and the like may be, all can agree that they cannot compete with free heat.  Underground Sunshine One of the most interesting ideas to bubble to the surface lately has been aquifer heat storage. The diagram below shows how solar energy is being converted into hot water by running it through fine wire (FiWiHex) heat exchangers, and then stored in the ground for heat season. Obviously, your groundwater must be static, not too shallow, etc., but if conditions are right…presto! Free heat.  Feeding The Beast Ben Cecil, propagation and container […]
