Ceiling Fan Blades

The blades of a ceiling fan make all the difference. The amount of airflow a fan generates depends on the type and size of blades it has. Most ceiling fans have four blades, but they can have as few as three or as many as five. There are several important things that affect the operation, production and lifespan of ceiling fan blades. The length and width of the blades determines how much airflow they can generate. The tilt of the blades also affects the fan's ability to distribute air as well. Another variable in ceiling fan blades is the material used to make them.

Ceiling fans are not measured by the length of the individual blades, but by the total radius of the fan. For example, a 52-inch ceiling fan does not have blades that are 52 inches long, individually. Rather, 52 inches is the total length from the tip of one blade to the tip of the blade opposite it. Ceiling fans usually measure between 30 and 52 inches. Larger fans can generate more airflow, so they are best in big rooms. The width of the blades is also significant. Wide blades can move more air, but they often have greater air resistance and move more slowly than narrow blades.

The blades must be attached to the motor at an angle. Most are attached at an angel between 8- and 15-degrees. The sharper angles produce more airflow at lower speeds. Smaller angles provide less airflow, but they are more energy efficient.

Metal ceiling fan blades can be less expensive than wood blades, but they may not last as long. Wood blades can be treated to withstand corrosion and warping while metal blades can't. Wooden ceiling fan blades also operate more quietly than metal blades.

Ceiling fan blades come in a variety of shapes and colors. Once people know what size they need, they have their choice of which particular design is right for them.

In The News:

Tracking the progress of the third party testing we at PES are coordinating along with U-Plug Products LLC, of their 2 kW U-Plug magnet motor that is a 24"x6" portable cylinder weighing 20 pounds, expected to cost 2,000 USD. We want to run it three times longer (21 hours) than what the best batteries available could provide. (PESWiki; February-April 2016)
Pre-launch video announces a new LENR website coming March 1, 2016 at http://LookingForHeat.com The video is very well done as an entertaining piece that hopefully will go viral. (Free Energy Blog; February 21, 2016)
It's not easy to find a qualified testing agency that is also willing to sign off on something that appears to defy our existing understanding of the laws of physics. U-Plug has agreed to allow for a group of us scientists, including at least 3 PhDs to go test their unit and publish our report. (PESN; February 20, 2016)
So that this is quite clear, this is a test on a Regular Torch. NOT the ELFE flashlight. This is to compare them. 2 x NiMH AA 1.2v Battery's in a Regular Torch with a Halogen Bulb. Load is 2.8v and 0.85amps. (PESN; February 17, 2016)
Video explains the scientific principles behind how the ELFE flashlight harnesses endless free energy from the environment (Earth's magnetic field), which works better in some regions than others. It also shows the insides the torch. Uses the word "antennae," as one of the components. (PESN; February 14, 2016)
"The OPhone contains a capacitor that directly powers our phone. During extensive use this capacitor may become discharged, however this capacitor is being constantly trickle charged by Orbo. So after a period of time the capacitor will be recharged and the phone will be functional again. In essence the phone is charging itself." (Free Energy Blog; February 13, 2016)
The company that has figured out how to harness the earth's magnetic field to produce usable power and has been selling the ELFE flashlight (two more customer reports), is now developing a 3 kW generator. In two weeks, they are holding a business meeting for international distributors. (PESN; February 12, 2016)
Illinois company is gearing up to manufacture a 2 kW (115 volts, 17.3 amps) magnet motor that is load-following, portable, 24"x6" tube, weighing 20 pounds, very quiet, with 3-year warranty but expected to last at least 20 years with zero maintenance. Third-party tested. MSRP 2000 USD, beginning March, 2016, through distributors. (PESWiki; February 11, 2016)
The government agent who worked on this technology five decades ago, that is similar to Professor Steven E. Jones' Joule Ringer, thinks it is conceivable that we could eventually scale this solid state technology up to have a device the size and price of an air conditioner providing 20 kw. (PESWiki; February 9, 2016)
Nagendra Singh in Mumbai, India, informs us that they have built five of these and have two running for customers presently, in the 40 kVA range. "Presently it is too [expensive], costing 3200 USD per kva below 30 kva." (PESWiki; February 8, 2016)
The SunCell is described as a solid state "Sun in a Box." A 200 kW module would weigh around 250 pounds, with energy production cost being around 1 cent/kwh, so return on investment could be ten days. They are expected to be available commercially by Q1, 2017. (PESN; January 6, 2015)
"Today I received my Elfe Flashlight and it works. Time will tell if it meets the claims of automatically recharging, when depleted. If it holds, the claims a real breakthrough in FE technologie would have been accomplished." -- German customer (PESWiki; February 6, 2016)
The phone battery indicator stays near full even with heavy usage throughout the day. (The battery is charged by the internal OCube that pulls energy from the wheelwork of nature, solid state). (PESWiki; February 5, 2016)
The capacity of the Proton-3ND (Proton -3 Nano Diffusion) battery is projected to be 44 times the capacity of lithium batteries. Electric vehicles with these batteries would have more power and much more mileage at no extra charge. (PESN; January 4, 2016)
HH2 water fuel cell creates pure hydrogen off a 9-volt battery. This was a big diesel HH2 cell that was tested on a 16-liter Cat engine for CARB testing; yet it ran on very low amps and a low 9 volts. (PESWiki; February 3, 2016)
A former U.S. Government worker describes his effort to bring to public awareness (by highlighting things presently in the public domain) energy and anti-gravity technologies that the government had operational 50 years ago but has kept from the public. (PESN; February 2, 2016)
Imagine an incandescent bulb that is actually more efficient than LEDs! Well, it actually exists (MIT) and it does so by recycling light. (Free Energy Blog; February 2, 2016)
SMBC-Comics.com has posted a fun spoof on our skeptics. (Free Energy Blog; February 1, 2016)
"OK, so a lot of people are asking what's the difference between an Orbo power cell and traditional batteries." Batteries store energy, Orbo generates energy, then trickle charges a lithium ion battery.] (Free Energy Blog; February 1, 2016)
Mr. Keshe is as misleading in the field of free energy as he is regarding me. That has been my experience the years I've been exposedto his work. He takes something and blows it so far out of proportion that it barely resembles the fact from which it was extrapolated into infinity. He demands: "Close PESWiki now." (PESWiki; January 31, 2016)
They have achieved solid state operation using an electromagnetic pump to spray the molten silver between the electrodes for the 1000/second continuous pulsing for continuous power production. (Free Energy Blog; January 29, 2016)
