This video shows the complete build of a Portable Rocket Mass Heater. This heater goes together like an erector set and comes apart just as easily. It’s custom mini mass. This heater can save you up to 80% on your heating bills. It is super efficient. This heater is beautiful and built completely from reclaimed and repurposed items. This rocket mass heater is Artistic one of a kind! This rocket mass heater is made with air crete, and is budget friendly, handmade, and better than a wood stove.The advantage of this rocket mass heater is the huge increase in the efficiency of capturing and storing the available heat.
- How to convert an Old Ceiling Fan Motor into a 70W Efficient Single Phase Alternator GeneratorThis project goes over the conversion of an old ceiling fan motor into an single phase alternator .You can't take your standard AC electric motor and spin it and get an electrical current out of it unless you modify it. The ceiling fan motor used here will produce about 70 volts at one amp which is roughly 70 watts. Through a bridge rectifier we can get about 70 watts of power out of it. We start by pulling the cover of the fan. Inside we have a squirrel cage rotor in the middle and 6 coil windings around it. The coil windings are placed in clockwise and anti-clock wise directions inside the stator. Next we remove the circular rotor from the threaded shaft which is attached to it with help of a vice. We attach the shaft with the rotor through it within a vice. With the help of an extra piece of pipe to give leverage, we press them against the rotor and push it away from the rod and pop it off. We are replacing the rotor that we have detached from the shaft with a two inch hex steel bar . It has six sides that matches with the six coils from the stator. With the help of one eighth inch drill bit we cut a hole in the center of our hex bar. We put the hex bar through the shaft and fit them snugly around the threaded area. We take six one half inch neodymium or rare earth magnets and place them along the the 6 sides of the hex bar. We place them in such a manner that the poles of the magnets are opposing each other. For permanent usage, wrap this with a little bit of tape or glue so that they are held in place securely. We place our modified rotor in the middle of the stator and align them such that they fit in tightly. The outer screen is bolted back onto the motor. We can also add second set of magnets to increase the magnetic field of the rotor .This will also bring it closer to the coils on the outside and increase the overall voltage. To convert the alternating current generated by our ceiling fan alternator to direct current, we use a bridge rectifier. It has 4 poles, 2 for connecting our alternating current, the other plus and negative for DC power. https://www.youtube.com/watch?v=k-4IbLOZwnA
