This video shows you how to build a Mini Hydrogen Generator / Water to fuel Generator using materials that is easily available around your house.This is achieved by Electrolysis which is an electro-chemical process whereby which hydrogen and oxygen are disassociated from water.By means of electrical influence using simple water one can get gas, and gather in into a special container and use this gas (hydrogen) for power supply of engines or other appliances.It is preferred not to use salt as electrolyte it will release chlorine gas.You can use sodium hydroxide, which can be bought as a “drain opener” at lowes or home depot, you could probably use any type of hydroxide though.
- How to Generate Emergency Off Grid Power using a Car Alternator and an exercise bike.This project goes into the build of a DIY pedal powered generator out of an old car alternator and a bike. This generator is useful for powering your devices and gadgets in case of an emergency or grid down scenario. The materials you need to build this generator are bike, MDF for base plinth, magnetic trainer stand for bike, Alternator, drive belt, 12V battery, cable connectors, 12V socket, multimeter, screwdriver, insulation tape. The rear end the bike and rest of the components are mounted on a one inch thick MDF board. This has a good amount of stability that keeps it away from moving around. We add an extension bit on the front. The extra height there just compensates for the fact that the back wheel is in a stand. The alternator is mounted nice and secure onto the base using brackets. Bolts connect the alternator to the brackets and screw the brackets down to the base. Once you are pedaling, and you have got electrical load in the circuit, there is quite a bit of force pulling the alternator forwards. So it does need to be really securely bolted down. Make sure that the wheel of the bike is in line with the alternator pulley .With any wheel, we have rim bed and the rim walls. Here what we need is a drive belt that fits purely in the rim bed. Make sure you measure the internal width of the rim bed . Also measure the width and depth of the alternator pulley grooves and get a belt that fits accordingly . Also make sure you have got a belt that is long enough because a typical drive belt that is used in a car is not going to be long enough because it is only made to go around a pulley on the engine. The car alternator used here has three wires coming out of them .It has a main power thick output wire, it supplies main power to the devices. Then there is two small cables, one for voltage sensing and the other for field coil ignition. The voltage sensing wire goes straight to the 12V lead acid battery in our case. To get the alternator generating power you first need to apply a small voltage through the field coil and that is because an alternator doesn't have any permanent magnets in it. The way that any generating device works is moving either electrical charges through a stationary magnetic field or moving a magnetic field around a charge. So the field coil inside the alternator is attached to the field coil ignition cable, and putting a voltage generates the magnetic field, which enables the alternator to generate power when you turn the shaft via the drive belt. You don't need to keep applying a voltage to it as it's running, because it will generate its own power. The negative from the alternator is connected to the negative of the battery. The positive connection from the alternator is connected to the positive of the battery. The third connection coming from the alternator is the field coil activator .This is connected to a switch .The connection goes back to the alternator to active the field coil. A standard cigarette lighter socket is connected to the battery terminals. It will draw power off the battery first, and once you start charging power, because the alternator is connected into that, it is going to draw it from the alternator, and the alternator will simultaneously power whatever is connected into that socket, and recharge the battery. The alternator used here has voltage tolerance of 11 to 14V . A Modular splitter is connected to the cig power socket to charge multiple devices. Make sure that the plug comes with a fuse or whatever you plug in needs to be rated to the right power for what you are going to charge . To run alternating current devices, we connect a 150W Power inverter to the circuit. The alternator actually generate alternating current. But its got a rectification circuitry built into it, which changes it to DC. The inverter changes the the DC output from the alternator to AC. Finally ,we add a master switch that switches the battery on.The Power switch stops any drain from the battery through the field coil . The switch also connects the multi sockets that charges various devices. It isolates the battery from the circuit. It isolates the alternator from the circuit, and it isolates the remote switch and the battery from the field coil completely. The AC generating device like an alternator have a minimum speed of operation in which they are stable. So do check for your alternator, what is the recommended minimum speed for it. If you spend it below that speed, what happens is because of the way it works, you get a periodically varying force which acts as a resistance to your pedaling. https://www.youtube.com/watch?v=_Hx1ptv6RKI
- DIY Video : How to heat your garage the Inexpensive way by building an Outdoor Stove with Heat ExchangerThis project goes over the build of an inexpensive garage heater using DIY outdoor barrel stove with a heat exchanger. This outdoor setup is safe because you dont want the stove inside the garage to catch fire if you are working with any flammable gas. We use a 30 gallon drum for the stove. The access doors and legs are purchased from the local store. The heater exchanger is made out of four inch steel pipe .We take couple of 4 foot pipe and weld them together using another small pipe. This pipe goes inside the firebox and connects to the chimney pipes. The pipe should be thick enough that it can withstand the heat of the fire without sagging or bending. This pipe heat exchanger adds positive pressure . Removable hatches are made on one side of the stoves to connect the 2 four inch aluminum flex chimney pipes from the outside barrel to the garage. Inside the garage we place a 4 inch exhaust fan blower that sucks the colder air from the floor and blows it through one of the flex chimney pipe into the stove. The blower is actually a hydroponics duct exhaust fan purchased from Ebay. The cold air gets pushed into the stove and moves through the heat exchanger steel pipe , gets heated and then moves out through the second chimney flex pipe and back into the garage. The hot air from the stove moves into the garage through the second pipe. In order to get more hot air, we also add a drip fed waste oil system to the outdoor stove . The oil gets dripped slowly from a tank into a frying pan on top of the stove .You can add cotton rags and let it drip into there and it just keeps burning like a wick. The combination of both wood and waste oil produce better fire . If the stove gets too hot, you can turn of the oil or use oil only to maintaining the temperature. You can put an insulated shack around the stove to minimize the heat loss. https://www.youtube.com/watch?v=fn4CerxpNug
- DIY Video:How To Turn Your Old Fan Into An Airconditioner AC for cheap.This project shows you how can take an old table fan and convert it into a simple ,cheap and easy to make homemade AC . The materials needed for the this project are a table fan, 75 gallon per hour fountain pump with valve to control the water flow, multi purpose zip ties ,two 3/8th inch transparent PVC Pipe tube, 15 foot quarter inch copper tube,two hose clamps. Unhook the locks if any and remove the screen of the fan. Take the copper coil and wind them across the rims of the fan .Secure them tight on the screen using multi purpose ties. Add the screen back to the fan body and then adjust the two ends of the copper coil by bending them to face the back of the fan and secure them using ties. Two 3/8 transparent vinyl PVC pipes are connected to the copper tube ends using hose clamps. We attach the fountain pump to the end of the vinyl PVC tube that goes straight into our cooler. The recirculated water coming from the other end of the tube goes straight back into the cooler bag. The cooler bag is filled with ice packs and water. The water pump is submerged into the bottom of the bag with ice and water over it. The water which is pumped with the help of the fountain pump gets recycled through the vinyl and the copper pipe and moves back into the bag, so you dont need to add more water .Both the pump and fan can be connected to solar generator in case if you want to make the system portable . https://www.youtube.com/watch?v=5NuvzWaBulw
