This video shows the build of a simple Homemade Water-Chilled” Radiant Air Cooler! w/motor speed control!.Made with an 8×8 “water-to-air” heat exchanger, small water pump and a 7″ fan. This new design cools air by pumping ice-water (or cold water) thru a water-to-air heat exchanger (copper/aluminum radiator) and then drawing the warm air thru the unit using a 12v radiator fan. the air that is produced is cooled dramatically with no increase in humidity and no need to vent any part of the unit to the outside. the heat is essentially captured into the cold water and the “cold” in the water is released into the room as cold air.

- How to build a Super Efficient Outdoor Wood Stove Heater from an Old Propane BottleThis project goes over the build of an efficient outdoor wood burning stove heater out of an old propane bottle and some scrap metal from the scrapyard. This stove has secondary burn system that helps in combustion of any unburned smoke or fume inside .Almost little to no smoke coming from the flue pipe. The first step is to make sure that the old propane tank is empty. We take the valve at the top by removing the valve protector cage. Fill the tank with water and let it sit for a few hours before we drain the tank and start cutting top and bottom. With the help of a hole saw cutter ,we cut 100mm four inch holes at the top and bottom of the tank . The top hole is for the flue pipe to sit in and the bottom hole is for cleaning the ashes out. We also remove the bottom stand too. Next, we cut a hole for the door for the stove. This is cut as high up to the top of the bottle . The door is made of chequered plate piece . We fit a rectangular pyrex dish glass piece in the middle of the chequered plate that can withstand high temperature with couple of steel bracket pieces. The glass on the door helps us to see how the secondary burn system is working inside the chamber. The door is attached to a frame through hinges. The flue outlet on the top the tank is attached through a flange piece with holes. The door handle is made of a socket wrench. The wrench is bolted to the plate and a small metal piece is welded onto to the frame to which the wrench is pulled to close the door A deflector plate made of small holes is installed inside the stove on the top . We drill 8mm holes around the top of tank and put dome bolts across them. The deflector pipe sits on these bolts. The deflector plate stop the unburned gases exiting out the flue outlet pipe. This encourages the flame that rises, pass through the deflector plate holes into the secondary burn chamber that helps in better combustion. The secondary burn system is made of stainless steel pipes .The air intake section is long enough to get the air coming in to get super heated and move into two sections filled with holes. Since not all gases from the wood combust from the primary air intake, the secondary burn pipe ensures that the air gets super heated before exiting the pre-drilled holes and helps burn the unburned gases rising from the fire before exiting the flue pipe. The secondary air intake pipe coming out of the firebox is welded on the top of the tank with a flange piece. The primary air intake pipe that goes under the door frame is made of a two inch coupler and threaded damper disc. A small metal piece is welded to the coupler with a hole in the middle. The damper disc screws in through the hole that allows us to close and open the intake .
- How to build a Backyard Waste Oil Burner Powered Water Heater to produce Free Hot Water for your HomeThis projects goes over the build of waste oil powered free hot water heater for your home .This converts an old used domestic water heater to run on waste oil, engine oil or cooking oil. With as little as one liter of waste oil, this heater gives twice the heat output than a domestic electric powered water heater .As waste oil is free, this is more economical than running on gas or electric. The setup of this waste oil heater is very simple and easy. We have a waste oil burner that is placed under the domestic water heater. The burner is connected to a blower from a car. This blower is powered by a 12V battery charger . The burner is also connected to a drip feed waste oil pipe through a small pipe. The oil feed from a suspended tank, which gives it a gravity feed dribbles into the inlet pipe on the burner and it is simply blown into the burner by the force of the air from the blower. To control the oil flow ,we have a valve on the oil tank. The cold water comes into through the inlet hose at the bottom of the tank . From there burner just fires the heat up through the center of the heater as it would normally if it was gas fired. The hot water comes out from a outlet hose at the top of the tank. The waste oil burner is made out an old fire extinguisher bottle. The beauty of using extinguisher bottles is you don't have to worry about any flammable gases in them, and the metal seems to be quite durable. Make sure that the air and the fuel enter the bottle at a slight angle in order to create some swirling. This makes sure that the air and the fuel mix and will burn completely. And also that the bottle is kept hot so that the liquid oil will vaporize and the gas will burn. The inlet pipe for the waste oil and the blower is positioned at 25 to 35% of the way up to the bottle. The inlet pipe has a small bend in it so as to promote swirling within the bottle. This is important in keeping the bottle hot and self sustaining. The burner has a clean burn with almost no smoke. The output of the oil burner can be controlled by the amount of waste oil being dripped into the burner and by the amount of air blown into it. This oil gas burner is more powerful than a gas burner and the heat produced can overpower the heat sink threshold of the water heater . A vent line is installed on the system so that any build up pressure can be released. Apart from heating hot water , this set up can be used for space heating , pool heating or garage heating. https://www.youtube.com/watch?v=L4xq_GSjWLI
