They are portable road ‘matrix’ signs with self contained power packs – usually solar panels & battery -or for more long term use , a diesel generator. They have a radio link to the area police traffic office so they can be updated as necessary to inform of delays or diversions ahead

As far as the person who said that solar lights are only good for accent lights, I am assuming they have never bothered to buy quality fixtures. With solar, you get what you pay for.

Solar shed lights would be great, or solar panels that you could use to charge radios, etc. Solar sheds lights are easy to install and use and they are bright, last for 3-4 hours continuously on one charge. You mount the solar panels on the roof or a sunny side of the barn. Then, you drill holes to connect the solar panels to the solar lights inside. Good shed lights come with materials that seal the area where the cord connects through the wall or roof. See below for a few options that are well worth the money.

There are also portable solar lamps that you can move indoors after they charge. And yes, we sell them but we also use them quite efficiently. Feel free to call us and we’ll try to work out a deal for you. Rechargeable lights are also good, but you would have to bring them with you each time you hang out.

Hey Chris, Homer is correct in that the device you speak of does not extract free energy from thin air. It has been called the Tesla Coil, Tesla Generator, and lately the Tesla Unlimited Energy Device. The device is a receiver. What Tesla was trying to get at was that energy can be pumped into both the earth and the atmosphere, transmitted over long distances and picked back up at the receiver to be used for whatever purposes were desired. This free energy has to be produced and put into the atmosphere first, purportedly by a power company. It isn’t free, but the problem is it can be pirated at any location with the use of another Tesla Coil, which means less of it is now available for the receiving coil that may have been originally built to receive the energy in the first place. It’s like a bank using a high power cannon to blast dollar bills into the air that are carried on the wind until someone on a tall hill reaches up and grabs them as they drift by. It isn’t free money, it’s the banks, and they’re going to want someone to pay for it. The dollar bills do not occur naturally as a result of atmospheric movement, they have to be put there first, same as Teslas free energy.

Well in the end, we do transmit energy over long distances, with the use of a wire, and then anyone willing to pay for some of it can hook their wire to the long wire with a meter to keep track of how much they are using so the electric company can pay their bills too. You don’t have to get your power from them however, we don’t. Our home generates its power from the wind and sun, now that is free energy. While solar photovoltiac panels have only been around 50 years or so, wind power dates back to the 3rd century, even before Tesla showed up with his building sized lightning producing hairbrush. You don’t have to be a physicist to make a wind turbine or a solar panel work either, we put ours in ourselves 10 years ago and it still works fine today.

UFOTV.com has an interesting video on this Tesla Unlimited Free Energy, how anyone can build a receivier and extract energy from the atmosphere for free. They are also publishers of videos and MP3 downloads on such proven scientific endeavors as, “Inside the Alien Mind,” and, “Unknown UFO’s today.” If that’s the source of your research, check and see if you can finish their latest MP3 download before the next ship lands in the desert. I found it interesting that this Tesla device can be built with common substances and ordinary tools by anyone handy, while at the same time claiming the notes on its construction were somehow mysteriously absconded with. If we don’t have the notes, how do we know what the thing is made out of?

If you want to learn more about Tesla energy transmission, check out Wikipedia, or physicsforums.com, they have a pretty good discussion on the system and how it actually works. If you want free energy instead, check out solar and wind at some of the sources below, we did years ago, it’s how we got to where we are today. Good luck Chris, and take care, Rudydoo

Hey Cat, Gatorbait has a good resource listed there, AWEA, or American Wind Energy Association. To cut to the chase, most modern turbines today never make it past 25% efficiency, regardless of how hard the wind is blowing or what their design speed is.

First, the highest efficiency that can be attained by any wind conversion technology was discovered by Albert Betz, it is called the Betz Limit, which is 59%. Once you begin extracting this level of energy out of the wind, the direction of the wind is altered nearly 90 degrees and moved outward, which destroys its ability to push the blade around on the next pass. You can read about it at the link below, there is a fair amount a calculus involved. A really well designed blade operating at its ideal wind and rpm speed today might reach the upper 30’s, or maybe low 40’s, but this says nothing for the efficiency of the generator or gearbox. There is also the fact that a small amount of power is used operating the controls of the machine, like unfeathering blades, turning the unit into the wind (this is done with a motor on the large utility sized machines instead of a tail), and the fact that some of these controls operate when the wind is not blowing, waiting for the moment it does.

To boil it down, on a good day, you might see 25% from a good turbine overall. That might not sound like much, but consider some of our mainstay techology efficiencies today: Incadescent light bulb 4%, gasoline car, 24%, solar electric, or photovoltiac, panels, 13%. There is plenty of energy in a passing column of air to make electricity from one large turbine to run an entire village, and once you build and install one of these devices, you never have to feed it again. This is why all the power companies are busy putting them up, they make so much more sense than coal or natural gas once you get just a few years down the road. The fact that they operate cleaner is exciting, but is really a side note to why companies are spending so much money on them today. I’ll list some sources and links below for you to check out.

One word of caution, in the 11 or so years we’ve been powering our home with the wind and sun and teaching renewable energy seminars at the local schools, I’ve found that there are 3 things in vast supply in the area, sun, wind, and missinformation. It is amazing to me how many people will weigh in on a topic like this never having laid a hand on a turbine our a panel. Stick with the sources below, and rely on your own research and intuition instead of asking hacks like us online for advice on renewable energy, you’ll be better informed in the end. Take care Cat Man, Rudydoo

From a Wikipedia Article:
The aerodynamics of a horizontal-axis wind turbine are not straightforward. The air flow at the blades is not the same as the airflow far away from the turbine. The very nature of the way in which energy is extracted from the air also causes air to be deflected by the turbine. In addition the aerodynamics of a wind turbine at the rotor surface exhibit phenomena that are rarely seen in other aerodynamic fields.

In 1919 the physicist Albert Betz showed that for a hypothetical ideal wind-energy extraction machine, the fundamental laws of conservation of mass and energy allowed no more than 16/27 (59.3%) of the kinetic energy of the wind to be captured. This Betz’ law limit can be approached by modern turbine designs which may reach 70 to 80% of this theoretical limit.
