Generates its own electricity

These fans generate their own electricity using the heat from a stove. The fan acts like a large heat sink, drawing heat from the stove up through the aluminium base. Half way up the base is a  peltier  cooler. The temperature difference between the bottom and top of the base causes the  peltier  cooler to produce low voltage electricity. This powers the electric fan which blows warm air around the room. Suitable for an Aga or wood/oil burning stove.  What are the advantages of using it? Stoves are good a  radiating the heat, but can sometimes leave parts of the room cold while, closer to the stove is lovely and warm. You may find yourself sitting closer to the stove just to keep warm. Theecofan  helps to reduce this problem by blowing warm air around the room. The ecofan  is a best seller in narrow boats where one end of the boat can be hot (by the stove) and the other end cold.  Note:  The fan will run slowly on a hot radiator or on top of a hot cup of tea/coffee, which makes it ideal for class room  demonstrations.  The Peltier-Seebeck effect The peltier  cooler in  this fan uses the Peltier-Seebeck effect. In 1821, Thomas Johann Seebeck discovered that a solid metal bar that had a large temperature difference between the two ends produced an electric current. In 1834 Jean Peltier  took this discovery further by observing that two different metals or semiconductors that are connected in a particular way (Peltier junctions) could act as a heat pump if electricity was passed across them. In other words heat would be pumped from one side to the other, creating one cool side and one hot side. Peltier coolers are often called thermo-electric coolers (TEC).

our  experiments we used the  Heat Powered Stove Fan  (pictured above)  This is a 23 x 20.5cm fan in a satin black finish which is designed to sit on top of the stove  The fan  stand comprises two parts - the base which heats up on the stove, and the top which has fins so that it cools quickly. A peltier  module  is sandwiched between the top and the base and generates electricity  when there is a temperature  difference between the top and base. This electricity powers the motor which drives the fan. It is almost impossible to conduct true scientific experiments in a real world situation with this type of fan. It is impossible to completely thermally isolate a room from the rest of the house while the rest of the house is being heated (or not being heated), and while the temperature outside is changing. It is also extremely difficult to maintain the stove at a constant temperature - therefore, while it is possible to run the stove with and without the fan and collect data, it is difficult to say for sure whether the room heated up more quickly or whether less fuel was used to heat the room to a certain temperature when the fan is used compared to when it is not.

The Experiment We decided to run the following experiment. Using a 4kW rated  multi-fuel stove  in a room which is 3m x 4m x 2.8m (high) we set up an accurate digital  temperature logger  at a height of 1.2 metres  at the wall opposite the stove (3.2m from the stove). This would then record the temperature felt by people sitting in their usual position on the sofa. We would perform this experiment in the evening as the outside temperature was going down, and leave all other heating off in the house so we know its temperature was falling too. We would then get the stove burning with the stove fan  not in place, and fill it with wood. We would watch the temperature rise as the stove got hotter and hotter and circulated hot air around the room. Then later as the fuel in the stove is partially consumed and the stove starts to cool, when the temperature measured at the thermometer  starts to level off or drop, we would then put the fan on top of the stove. If the fan works we would expect to see a spike upwards in temperature, and if so, since the outdoor ambient temperature is going down, the stove is cooling , and the rest of the house is cooling , we would know that the effect was due solely to our stove fan .
