Energy Efficient Homes: Scott Bergford

Energy Efficient Homes: Scott Bergford

Scott Bergford has spent his entire home building career searching for the balance between energy efficiency and affordability. For nearly 30 years, Scott has worked to build homes that exceed building codes and use little energy to run. He also now retrofits existing homes for greater energy efficiency. Scott feels there is inestimable value in collaboration between new discoveries and proven “traditional” building technologies. Today Scott’s homes are certified to the highest ranking of Built Green ® and Energy Star. Scott Homes is one of the few builders in the nation to achieve “Emerald” certification from NAHB Green program.

Homemade Wind Turbine | Project Guide for Kids

Homemade Wind Turbine | Project Guide for Kids

I have been thinking to make wind turbine (a large horizontal axis one) since I first published a small wind turbine video on youtube and a blog post here a few years back. That video went viral. Then I decided to make one large functional wind turbine. The former didn’t give me even 1.5 volts. I know building a medium sized wind turbine will take a lot of time to complete. But, It didn’t, I’ve Just finished a medium sized wind turbine with only 5 days, 2 hours per day after my regular work. By the way, Here I am going to give you an overview of my experience in making this wind turbine Project.

Make Wind Turbine

1.Propeller Making

A propeller is the most important part of a wind turbine. The propeller is used to convert wind energy to rotational energy. This rotational energy can easily be converted to electricity by coupling it with a dynamo. Wind turbine blade should have appropriate curvature and weight to get maximum efficiency. So, I bought 6mm thick, 8 Inch Heavy duty PVC pipe (). Then I used a hand grinder to cut it into wind turbine blade shape with 1:3:20 ratio.

You can easily make rotor to connect these blades using a Plate washer, Nut, and GI L-clamps.

Take 8 inch, 4mm PVC Pipe

Cut it into blade shape 1:2:30 Ratio as shown in the figure

Smoothen the edges.

Take a 3 Inch washer and weld GI Pieces on It.

Screw PVC blades On it.

2.Turbine base Making

Another important function of a wind turbine is its ability to face the wind automatically. Otherwise, it won’t be able to maximize the wind energy harvesting. This mechanism is called yaw mechanism. It works with the help of a flexible turbine base and a tail. I used a johnson wheel to make this flexible joint.

The tail will help the propeller to face the wind. As a result, we will get maximum output. We can cut aluminum sheet very easily to any shape. Cut it to a proper shape.

Take a Johnson wheel and remove the wheel

Weld it to one side of a 1″ square GI Pipe (1.5m)

Connect bearings in a Piece of GI pipe and Place it on the johnson wheel.

Weld a hose clip on it to fix dynamo.

3. Tail Making

The tail will help the propeller to face the wind. As a result, we will get maximum output. We can cut aluminum sheet very easily to any shape. Cut it to a proper shape.

Cut aluminum sheet into wind turbine tail shape

Screw it on a GI Piece

Fix the tail on Wind turbine Base

SAFETY FIRST APPROACH

Keep in Mind that safety must be the first priority. If you are not familiar with angle Grinder, I strongly recommend you not to use it. In any case, children should not experiment with it. Also, when welding you should wear eye protection glasses, face shield, and hand gloves. Ask professional welders to get your work done. That would be better. I have worked as a welder and wireman two years, so I have some experience it such things. Thank God.

4. Assemble Each Component together

Watch Video Closely to assemble each Component Together. Make sure the crank wheel and flywheel align straight. Then Connect the output to a battery or multimeter. Place the wind turbine outside where the wind blows.

That’s It, make wind turbine Project is ready

New Wind Turbine Technologies

The new wind-lens turbine

A Japanese research group is working on a new technique that could triple the output of wind power generation. Called the wind-lens turbine, it gathers the wind much as a lens concentrates light by means of a special device that is attached around the turbine. So, what could that be? Look forward to this! It’s simpler than you’d think! Tests have already started on turbines out at sea in preparation for practical introduction. Effective use of the wind around Japan’s coasts could far more than satisfy Japan’s electricity needs. We report from the vanguard of this dream new technology.

Free power- How to convert an old washing machine into a water powered generator

I’ve been living off the grid for a few years now, using a converted water powered F&P washing machine motor to generate more than enough power to run all the appliances & hot water I use in my house, as well as powering all the tools I use in my workshop. In that time I’ve saved many thousands of dollars from not having to pay power bills. In this detailed video I’ll show you how it’s done.

I’m told Whirpool Cabrio and Maytag Bravos use the same type of stator motor for those who can’t find this model.

The Inflection Point for Solar Energy | David Galipeau | TEDxBrookings

The Inflection Point for Solar Energy | David Galipeau | TEDxBrookings

This talk was given at a local TEDx event, produced independently of the TED Conferences. Solar energy has been hailed as the future of energy for decades. Finally, solar energy has reached the inflection point where it not only makes technological sense, but also economic sense.

Dr. David W. Galipeau is the Harold Hohbach Professor of Electrical Engineering and the Coordinator of the Center for Advanced Photovoltaics and Sustainable Energy; and Electrical Engineering MS and Ph.D. graduate programs at South Dakota State University. He was also the program lead for the Alternative Power Technology (APT) Program supported by the Department of Defense. While at SDSU, he has been the PI or Co-PI on over forty funded research projects, including twelve major NSF awards for over M and eight SBIR-STTR awards. He has published over 100 research papers, given numerous presentations, and established a spin off business. He was also Co-founder of the Center for Advanced Photovoltaics and Sustainable Energy.
