This Video shows the build of a Solar Evacuated Thermal Vacuum Water Pump works by harnessing the energy of the sun in the day time and then uses the cold of night to create a vacuum in the system that is used to pump water. This is a working prototype of an idea on how to pump water from stagnant water sources cheaply using no moving part.By using the sun’s energy to generate both a pressure and a vacuum cycle we create a very efficient water pump, that has only two simple moving parts. This pump was able to move one gallon every cycle to 8 feet high, by creating artificial day/night cycles the pump could move about 1 gallon every 30 minutes of sunlight, or about 12 to 20 gallons a day.

This video shows the build of a Simple Pex Coil Solar Thermal Water Heater.asy DIY! No Soldering, Clamps, Crimp Rings, Glues, Unions, or that expensive crimping tool! in my design it’s just 2 push-to-fit “shark-bite” connectors! (located outside of collector) and because it’s all one piece of tube, the unit has no potential internal leak points.PEX is sturdy, tough and rigid. water temp rating range… 33F to 185F-200F (93°C) water! …and if temps hit or fall below 32F (0°C) it’s freeze damage resistant! it’ll freeze but doesn’t break. the connectors are made to last at least 25 years and pipe is rated 50+ years.

This Video shows the build of a Homemade 12VDC Mini Box Fan! w/motor speed control!Powered with a 12v battery or 12v solar panel! Made Sturdy and is SUPER POWERFUL! pushes more air than a fan twice its size.Ithas a whopping 1500 CFM air-flow volume with wind speeds measuring in at over 20 MPH! (32 kph) and with the motor control switch you can set it to run at any of 100 different speeds! .Great for off-grid use, camping, emergencies or everyday use. tip: run it from a cars’ 12v cigarette lighter plug.

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.

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 8×8 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).

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.

This video shows the generation of Unlimited hot water 100% Off the Grid without electricity by converting an old propane tank to burn underwater as an immersion heater for a lot of hot water.Here,I use a homemade underwater wood stove to make a lot of hot water in a relatively short time.I also make use of the waste heat to cook breakfast.Almost 75-80 gallons of hot water in 1 hour with wood.Really a great way to heat a lot of water.

This video shows the build of a redneck style off grid wood burning heat exchange we use to heat our house in the winter. It will keep your home warm without electricity, or using the furnace. The air comes in through the front, where there is a lot of spaces along the bottom of the barrel, then gets heated and rises through the duct in to the house.Here,the air from the house does not go into the exchanger, it only pushes warm air into the house.

This video shows the build of a $100K worth WaterJet Cutter for about $200 using a cheap pressure washer.Waterjet is the ultimate machine tool, no matter the application.This is because its a Cold Cutting Process which means no heat or stress is imparted into your cut materials.Also you can take the part directly off of the cutting table, no secondary finishing required.Also it eliminates slag deformation and dross waste – unfortunate effects found in plasma and laser cutting processes.

This Video shows the build of a DIY Solar Heat Pump System .An air source heat pump consists of an evaporator coil, a condenser, two fans, a compressor, and plumbing lines containing a refrigerant. In simple terms, during the winter the large fan in the outdoor unit pulls cool outdoor air through the evaporator coil which causes the refrigerant inside to absorb what’s called ‘latent heat’ from that air, and then begins to boil and evaporate . Once the refrigerant is up to temperature, it passes through the condenser coil/heat exchanger where indoor air also passes through the condenser’s fins to absorb the heat from the refrigerant and deliver it where it’s needed.A heat pump is essentially an air conditioner working in reverse. Instead of pumping heat from indoors to outdoors, it’s pumping heat in reverse.
