  • DIY Video: How to build a Homemade Hot Water Off grid Air Heater using Heat Exchanger and a Car Radiator Fan
    This video shows the build of a Homemade Hot Water Air Heater using an old heat exchanger and a car radiator fan.This unit provides near-instant warm air.The Air-Flow: it's adjustable from 10 CFM to 1500 CFM. max breeze 20 Mph! The Temps: With input water temps between 120F to 150F the output air temp ranged from 85F to 110F. *or from heat pump temps up to near furnace temps! easily warms a room or two, maybe more.The heart of the unit is an 8x8 Copper/Aluminum Heat Exchanger., This unit can easily be run straight from a 12v solar panel or battery so it's "off-grid" ready. Simply mounted the fan in front of it,then connected the pipes. then you just connect a small water pump (200-350 gph) to one of the pipes and drop both pipes into a water-filled sink,almost immediately it creates very warm air (in under a minute).

  • DIY Video:How to recycle scrap metal in the backyard by building a simple Mini Metal Foundry from start to finish
    This video shows you how to recycle scrap metal in the backyard, with a homemade, Mini Metal Foundry.Depending on where you get, or find, your materials the cost can range anywhere from $5-$25 per unit. With the materials I used, I was able to make 2 units for under $40 ($20 each).Even on the high end, this is probably one of the cheapest, reliable, backyard foundries that can be made.I used mine to melt soda cans, and extract the aluminum for future metal casting projects. All the soda cans came from a local recycling depot.

  • How to Heat your Home for Free by building Solar Air Heating Collectors that uses no electricity or batteries
    This video series shows step by step the build and installation of a Simple Solar Air Heating Collectors that uses no electricity or batteries made from salvaged materials.The air enters at the center bottom of the collector, where an aluminum baffle spreads the flow across the width of the collector on the glazing side of the screen absorber. The air rises up between the glazing and the absorber, and eventually finds its way through the three layers of screen absorber and flows to the back side of the collector. The air then flows up the back side of the collector to the exit vent located at the top of the collector.
