  • 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).

  • How to build a Simple Homemade OFF GRID Refrigerator from easily available materials
    This video shows the build of an OFF GRID Refrigerator from cheap and easy to find materials.This design uses both the cooling effect of evaporation, and two water cooled condenser coil's. The fridge is shown using both a water ram pump at the end, and an electric pump powered by 12 volt/solar, it only uses 8 watts an hour using electric.There is an air gap between the sheet and the wall of the fridge because the water running down the sheet wont evaporate as well and that the water temp is not as low as the evaporative temp so the water touching the cooler could increase the temps and limit some of the potential cooling. If the power goes out and the fridge doesn’t keep things cool anymore – what other options do we have? If you are trying to live off grid and have no power source – how can you keep food and certain medicines cool and usable for longer?Then this Offgrid Refrigerator  is the answer.
