    I bet the rubber belt has jumped off the pulleys. I have a radio and a flashlight with the same problem. Suspect the rubber belt has stretched and will not stay on. I called Freeplay and they do not support the older models anymore. There should be a belt available that would fix this problem. Maybe an electronics drive belt, or possibly an o-ring that would fit.

    That's exactly the problem w/mine. The drive belt is stretched and slips like this when the unit is fully wound. Try 30 turns and see if it helps. I will look at McMaster-Carr. they have many esoteric items and have saved me many times.

The Freeplay isn't really designed as a crank and play for long term. Stick it in the sun on a sunny day and let the internal battery charge fully, it'll work much longer.

The drive mechanism has failed. try this. ensure it is fully unwound. then open it. then look for some part of the drive gears or belt that has broken or has slipped off. caution, you MUST ensure it is fully unwound prior to opening it.

Should we commandeer all the worlds golf courses and turn them into Wind Turbine farms?


Money Talks... putting in a Turbine Farm is not a cheap proposition.
I would need to sell the electricity and pay off the infrastructure, let alone the enviromental impact, and the regulations they require... and the permits... and the lobbyists who are pro Nucleur and Pro Coal... and Natural Gas
you cannot put up a turbine just anywhere... you need a 5 year study of the "Wind" favorability
I have experience of this tug of events... unless you have a buyer of turbine electricity who is willing to pay the higher price...think about the "not in my backyard". thought process... i'ts not just Trump...

Laser Lidar Guidance Adds Power to Wind Turbines The wind industry may soon be...


Laser Lidar Guidance Adds Power to Wind Turbines

The wind industry may soon be dependent on a different kind of environmental awareness that has more to do with lasers than ecology.
A new laser pointer 100mw system that can be mounted on wind turbines allows them to prepare for the wind rushing toward their blades.

The lasers act like sonar for the wind, bouncing off microscopically small particulates and back to a fiber optic detector. That data is fed to an on-board processor that generates a three-dimensional view of the wind speed and direction. Subtle adjustments in the turbine blade's angle to the window allows it to capture more energy and protect itself in case of strong gusts.
The startup company that developed the Vindicator system, Catch the Wind, recently deployed a wind unit on a Nebraska Public Power District turbine. It increased the production of the unit (.pdf) by more than 10 percent, according to the company's white paper. If those numbers held across the nations' 35 gigawatts of installed wind capacity, the laser lidar (Light Detection and Ranging) sensors could add more than 3.5 gigawatts of wind capacity without adding a single additional turbine.
"This is what they call disruptive technology," said William Fetzer, vice president of business development for Catch the Wind. "There are roughly 80,000 to 90,000 wind turbines out in the world, and they don't have this technology."
Wind farms are only as good as their data. There have been revolutions in assessing wind resources over long time-scales, but the short-term gustiness of the wind has remained a problem.
Current wind turbines rely on wind-measuring instruments known as anemometers that are mounted to the back of the turbine's gear-housing unit, called a nacelle. The data from the wind is fed to a computer that optimizes the blades' configuration to capture the most energy from the wind.

In many cases, cup anemometers, which took their current form in the 1930s, are still used. They work well enough, but have to be positioned behind the blades, which subjects them to turbulence. And, importantly, they can only tell you how fast the wind was blowing after it passed. That doesn't help you with a freak gust of wind or any of the odd behavior that renewable energy developers have caught the wind exhibiting.
Fort Felker, director of the National Renewable Energy Laboratory's National Wind Technology Center, said he saw great potential in laser pointer 200mw lidar and similar sound-wave-based systems generally.
"Once you have a detailed knowledge of the coming wind, there are a lot of opportunities," said Felker told Wired.com.
While he estimates the amount of energy that could be captured is below Catch the Wind's 10 percent, he said the systems could really help reduce the wear-and-tear on machines caused by strong winds hitting improperly positioned blades.
"Researchers have already demonstrated that substantial reduction of loads is certainly possible," Felker said.
laser lidar, despite first being demonstrated for wind measurement in the 1970s, has been slow to catch on. The systems have been too expensive.
"Widespread deployment of the technique has so far been hampered by the expense and complexity of laser lidar systems," a 2005 NREL research report found. "However, the recent development of laser lidar systems based on optical fiber and components from the telecommunications industry promises large improvements in cost, compactness, and reliability so that it becomes viable to consider the deployment of such systems on large wind turbines."
Now, even the most venerable R&D testing group in the world, the Danish National Laboratory for Sustainable Energy's Ris?e wind outfit, is working on a turbine-mounted laser lidar system, though they only claim a 5 percent increase in electricity production.

Catch the Wind grew out of a small-business grant that the company's predecessor, Optical Air Data Systems, received from the U.S. military. They developed a laser lidar system for helicopters working in the dusty Iraq and Afghanistan terrain. The company developed their rugged and relatively lightweight laser lidar systems by marrying aerospace knowledge with emerging telecommunications tech like better fiber optic cables and laser pointer 300mw diodes.
Still, Catch the Wind may have a tough road ahead. The energy industry is notoriously risk averse. Besides, wind electricity in many places is already cheaper than wholesale electricity prices.
Erin Edholm, a representative for National Wind, a wind-farm developer that's put in more than 4,000 megawatts of turbines, said that the company's wind resource assessment team "has not used [laser lidar] or considered using it to date."
But that doesn't dim the hopes of Catch the Wind's Fetzer for the company's ultimate success.
"When you do disruptive technologies, it takes time," Fetzer said. "People don't believe that things are as bad as they are until they can see what we can do."
It helps that they don't need the wind turbine manufacturers to incorporate their technology to jump start their business. They've got what's known as a "bolt-on" solution, meaning it can be attached to existing turbines. They don't need manufacturers to incorporate their product to sell it to wind farms.
Still, some wind farmers may worry that the warranties they have on their turbines would be voided by adding a laser lidar system. Fetzer said Catch the Wind is working out the warranty issues.
General Electric, which is the largest wind turbine manufacturer in the United States, is not using or developing laser lidar specifically, either. Catch the Wind did recently sell one of their machines to a large, unnamed turbine manufacturer.
Though Catch the Wind is not discussing pricing for their products, Fetzer maintains that their customers will make their money back in the three-to-five year range that he says wind developers are looking for. The 2005 NREL report calculated a preliminary cost for a generic laser lidar system of less than $95,000, once production was up and running.
The development of controls for capturing the most energy from the wind has been a constant theme in wind energy research. But it's not always the company that develops the technology that reaps the rewards from its commercialization. Wind turbines in the 1980s struggled mightily to convert the wind's gusty capriciousness into steady rotary power.
At the time, the turbine's rotor had to turn at a constant rate. Researchers realized that their machines could operate over a larger range of speeds if the rotor could speed up or slow down in response to the wind, but they would need power electronics to translate the power into electricity suitable for the grid.

A multimillion dollar R&D program launched by laser pointer U.S. Windpower and the Electric Power Research Institute to commercialize a variable-speed rotor resulted in a mostly defective turbine design that helped push U.S. Windpower out of business. The variable-speed rotor went on to become a standard part of wind turbine designs.
Catch the Wind obviously is hoping not to suffer the same fate. They are exploring a variety of business models including sharing the revenue from the extra power they say their systems can generate. If they don't generate any more electricity, the wind turbine owner doesn't pay anything. If they do, Catch the Wind gets half the take.

How does a wind turbine work?


A Wind turbine operates on a simple principle .The energy in the wind turns 2 or 3 propellor like blades around a rotor .The rotor is connected to the main shaft which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most wind energy.

When driving at highway speeds & there is a cross wind with rainy conditions; the wipers vibrate which creats a noise(loud noise, can not hear the radio or other ocupants talking).


Try, to find the type of wiper arms that have the wind deflector
built on it. The theory is the deflector is set at an angle that
the wind puts pressure on the wiper to push the blade to the
windshield??

OR the wiper arm hold down spring is just worn out
