DIY non-hub builds, the why and how (part-1) Common hub motor kits have a simple construction, which keeps the price low (especially with Chinese mass-production). The low price and easy installation makes them the big seller by a wide margin. However, if you want a build which has unusually good efficiency (so a smaller battery can provide longer range), or…you want unusually good hill-climbing…a non-hub drive system just might be necessary to deliver your goals. Be aware that a non-hub system will by definition be more complex, probably more expensive, and is likely to be noisier. And…the biggest problem is that a non-hub system will be either very expensive (like the EGO, and the M-Drive), or the more affordable drives have issues with longevity and component breakage (Cyclone and GNG). We’re not knocking Cyclone and GNG, they have no way of knowing if a customer is using their kits for light duty or racing…and non-hubs are often about reaching for exceptional performance.
DIY Homemade Tesla Coil Check our facebook page for updates and special offers The aim of this design was to get the highest voltage (or longest arcs) possible from a single self contained unit. Check out the new 1kW Tesla Coil! WARNING: High Voltage Device! This coil operates from 12V or 24V SLA batteries. A pair of car ignition coils are used to provide around 20kV for charging the capacitor bank. Plan your build Before you start cutting into your own grape juice containers and sealing be sure it fits in your car. Find a spot to cram your plastic container into. It needs to be away from direct conact to the motor.
Build an Amazing Tesla CD Turbine Build a real working turbine from recycled CD's! This Tesla CD Turbine is based on the Tesla turbine, which was invented by Nikola Tesla in the early 1900's. Tesla's pumps and motors were unique in that they only used discs, and took advantage of the boundary layer effect. His smallest designs were over 100 horsepower. This Instructable is an introduction to my recently developed Tesla CD Turbine, which is made from CD's, CD spindle, pipe fittings and glue.
Schematic of How to Build a Magnetic Motor There also is this so-called “free energy”, the zero-point energy, proven mathematically by many scientists. My duty as a green optimistic is to collect everything I see someone has struggled explaining and demonstrating, put it in one place and let the people see and comment. Such is the example of this magnetic motor. But there are also “green pessimistic” websites. When they see something out of “common sense” boundaries, they freak out and scream something like”omg, this can’t be real!
Build a 15,000 rpm Tesla Turbine using hard drive platters Here's a project that uses some of those dead hard drives you've got lying around. In the Tesla Turbine, air, steam, oil, or any other fluid is injected at the edge of a series of smooth parallel disks. The fluid spirals inwards and is exhausted through ventilation ports near the center of the disks. A regular blade turbine operates by transferring kinetic energy from the moving fluid to the turbine fan blades. In the Tesla Turbine, the kinetic energy transfer to the edges of the thin platters is very small. Instead, it uses the boundary layer effect, i.e. adhesion between the moving fluid and the rigid disk. DIY Water Turbine construction by HomesteadingSurvivalism Did you know that you can build a HYDRO TURBINE / WATER TURBINE for under $50?

How To Build Cheap Wind Generator using old Floppy Drive WARNING! Before connecting any USB device it is MANDATORY to check polarity and exact voltage (it has to be between 4.9 and 5.3 Volts) on USB connector using multimeter!!! Now we need to make the remaining mechanical parts for the wind generator. We need to prepare a bracket and a turbine (propeller). Bracket can be made out of aluminum tube with 3-4mm diameter. Do not forget to fix it firmly. How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. Window Socket – Solar Energy Powered Socket by Kyuho Song & Boa Oh The Window Socket offers a neat way to harness solar energy and use it as a plug socket. So far we have seen solutions that act as a solar battery backup, but none as a direct plug-in. Simple in design, the plug just attaches to any window and does its job intuitively. Designers: Kyuho Song & Boa Oh
8 Completely Awesome DIY Home Energy Projects Small-scale renewable energy is a must for a sustainable home – but converting your home to clean energy options can carry a huge initial price tag. We’ve scoured the web for some of the most innovative examples of homemade energy solutions to compile a collective list of DIY projects to make your home greener and more energy efficient without costing you a fortune. From solar water heaters and gadget chargers to homemade super-efficient refrigerators, you’ll find links (with instructions) to some of the best projects you can make at home… Homemade Energy-Save Fridge The ‘Ambient Air Fridge’ isn’t quite a year-round green appliance but when things cool down in the winter, this homemade fridge will definitely shave a few dollars off the electric bill!
Hydropower from Reuse Reused: a small stepper motor as found in a printer 2 discarded CD-ROMs a foam tray some long stick (I used a piece of 20mm diameter PVC tube from demolition) a LED one or two tie-wraps a small piece of scrap paper Non-reused: The only non-reused part is the hot melt glue (I recommend the low temp type, especially when working with kids). Tools: scissors, screwdriver to disassemble the printer (not shown), cutting pliers or desoldering tools for (optional, not shown). With a bit of luck the LED can also be found in the discarded printer.
Below sink - Ascot Hygiene Ltd Wijas Perfect below sink water heaters The Wijas water heater is the smallest on the UK market, measuring just 152 x 135 x 72mm. Click here to see how small. These non-vented heaters easily fit under a sink or in a cabinet to provide point of use water heating. They are extremely energy efficient too and you don't waste lots of running water waiting for the hot water to arrive.
