On December 10th in the year 1868, the first traffic signal light was placed into service. The bulky, primitive device employed colored lamps that were fueled by gas for use after dark, and semaphore arms. It required an operator to attend it at all times that it was in use. Twenty three days after that first traffic signal light went into service, it exploded – injuring the police officer who was assigned to run the lights and signals. This unfortunate event brought into question the practicality of implementing traffic signal lights.
Despite the volatility, and ultimately disastrous results, of using the first traffic signal light, stalwart inventors and engineers pursued the idea. As more and more traffic amassed on streets and roadways, the use of stop signs and officers standing on boxes at intersections became less and less practical – and more and more dangerous.
Sometime around 1912 the first electric traffic signal was put into use. These initial units only had red and green lights, however. In 1917 in Salt Lake City, Utah, a series of traffic lights were linked together, thus ‘connecting’ six sequential intersections. This system was operated manually with a single switch.
In 1922 Garrett A. Morgan made application for a patent on a traffic signal light of his own design. The patent was granted the following year. This started the myth that Morgan was the inventor of the traffic light.
Between the time the first traffic lights were introduced, and the early 1960’s many improvements were made, and many experiments conducted. The biggest problem with traffic signals to that point was simply that they were dependent on timers only. East-west traffic would get a green light for 3-minutes, and then a timer would trigger a green light for the north-south traffic – and so on. The lengths of time could be adjusted, but these settings frequently created problems with the flow of traffic.
In the early 1960’s traffic engineers started to implement “inductive loops” to control intersection traffic flow. The loops, which could detect vehicles in specific lanes at intersections controlled the lights’ timers. The inductive loops would switch the lights to accommodate the traffic at hand, based on the time of day. No more sitting at red traffic lights for 2-3-4 or 5 minutes - even if there was no cross-traffic present. Traffic engineers basked in a deluge of praise from drivers.
In the 1970’s technological advances in metallurgy, plastics, and rubber started changing the way vehicles were manufactured – and what they were being manufactured with. No longer was everything from the dashboard to the fenders made of high-iron content steels. It was in conjunction with these advances that the myths of tripping traffic lights began. Since then, it has gotten worse every year as more alloys, plastics, and rubber are used in the construction of vehicles.
It seemed logical that the amount of weight present at an intersection is what would trigger a green light. This is a myth. It also seemed logical that the mass present at an intersection would trigger a green light. This is also a myth. Since people were unable to make traffic lights trip by adding weight, or by having more mass to their vehicles, they started to seek other answers. The last most popular myth is that there is an invisible curtain that, when broken by a vehicle, triggers a green light. It is thought that the curtains only cover a portion of the lane, and if you do not violate the curtain, you don’t get the green light. This is also a myth.
Actually, inductive loop technology is very simple. An inductive loop is nothing but a very large, very weak electromagnet. The term ‘inductive loop’ refers to electromagnets used in industry to detect iron. They are commonly used in numerous industrial applications. They are inexpensive to make, install and maintain.
Inductive loops at traffic lights are created by burying large coils of thin copper wire slightly beneath the road’s surface. The wires are covered with either black tar or rubber. A small current runs through the wire, thus making it into an electromagnet. The loop is connected to a meter which measures changes inside the loop. Magnets react to iron – not plastic or rubber or aluminum. So when enough iron is present within the loop, the traffic light cycles to green.
The vehicles that have the greatest trouble tripping lights are motorcycles and mopeds, followed by small cars and trucks, and then raised 4×4s and SUVs. Drivers of these vehicles often sit undetected at traffic lights wasting fuel, getting rained on, their engines overheating, and their irritation growing.
To positively trigger your green lights, you can drag a bowling ball-sized piece of iron around on the ground – but that won’t work if it’s inside your trunk. That’s too far from the weak sensing field of the loop. In the trunk, you’ll need two or three large iron balls. OR you can install a Signal Sorcerer® traffic light changer http://signalsorcerer.com/.
Signal Sorcerer® traffic light changers use their own technology to make inductive loops detect your vehicle – no matter what size, weight, or mass it is. Simply install the Signal Sorcerer® under your vehicle, and the inductive loops that control traffic lights will detect your vehicle, and give you the green light!

City streets are congested and a kilometer distance would take hours to reach. It might be better to walk than to wait for the green light to turn on only to realize that your vehicle move only several meters. But you cannot walk. It is either scourging hot outside the car or heavily pouring rains. The thing is, there is nowhere to go on land. The only way to go from point A to point B is up there, above your head.
Helicopter is the only way to go if you want to travel fast and more efficient. It cuts off hours of sitting on the car together with thousands of cars around you that share the very same fate like you do.
Now you ask: I don’t own a helicopter, what should it do?
Two words: Helicopter rental.
Helicopter rental is the only solution if you want to escape the long pile up of vehicles on the road. Helicopter rental is the only solution if you want to spend more time on doing more important things than sitting on the backseat of your car.
Helicopter rental gives you the luxury of leaving your hotel room just minutes before your meeting or convention starts. It gives you more time to rest or to take longer shower or eat dinner. Or to simply put it, helicopter rentals provide the only way to always keep you on your schedule.
But this is not the only way to utilize the help of helicopter rental.
If in can you want to get some aerial photography of one place or a survey of a particular territory which would not be possible if done by land, helicopters can be rented as an efficient mean to meet the requirements.
If you are on an urgent business travel or would catch a corporate event and would need to get there as fast as you can, helicopter rental companies will quickly take you to your destination earlier that what you have expected.
If you want to see places up above the sky for mere pleasure, helicopters can be rented.
If you have a special event to hold and would want to make it a little different, for instance wedding, helicopters can be rented as your “bridal chopper”. This would certainly give you better reasons to feel like floating on the air.
Other ways to get helicopter rental would depend on your need. So if you find yourself needing to ride a helicopter for any occasion or reason, contact your nearest helicopter rental company today.

The elements of nature have been created for man alone. Every single need can be acquired and it is present in nature around us. Man only needs to travel and explore the hidden treasures of nature and use them for the fulfillment of his basic needs of life. Something that doesn’t need any searching shines up above in the sky. The sun is the basic source of life on earth. If there was no sun no life would have been possible.
Sun emits light which is known as the solar energy and you may have heard and studied about solar energy being used for thousands of purposes. This energy has been used for heating systems and thermal power plants are run through solar energy and so on. When you read or hear about these things you simply pass on because this is too common.
When it comes to solar powered cars it is very likely that you stop and think for a while. It is a promising future prospect and you wish you live long enough to see only solar powered cars racing down the streets, no running out gas, no waiting at the filling station, no more paying for the petrol. Imagine how quickly you would be able to increase your standard of living.
Solar powered cars have been in existence since the mid of the 19th century. They have been increasing in number year by year and organizations tend to hold solar powered car racing each year and thousands of people invest their money and bet on their solar powered cars. The mechanism of these cars is very simple. The batteries installed in these light bodied cars charge themselves from the solar energy. Then this energy is converted by them into electrical energy thus it helps the motor run.
Now this prospect is very simple or more likely it sounds very simple and trouble free. The sun shines everyday and there doesn’t seem to be any such problem with these cars. But the fact is that the amount of energy stored at a time by these cars enables them to drive at a very slow pace. The road has to be leveled and not steep because that requires even more energy. It will need more powerful batteries and more storage capacity.
Have you never noticed that this is the reason why solar powered cars are small; light weighed, and can carry one person at a time? There are many technical facts that render the concept of these cars as vague.

You’ve likely heard one of those chaos theory statements such as “If a pigeon lands on a statue in Trafalgar Square, and at the same time a tree falls in Yellowstone Park, then it will rain on Mount Kilimanjaro.” Baffling, isn’t it? Well, such is the nature of chaos theory. But higher prices for fuel at the pump are absolutely causing more and more people to sit at traffic lights that won’t change for them. It’s a very direct cause and effect issue – not at all chaos theory.
Unfortunately, people not being able to trigger traffic lights to cycle to green has the effect of causing more gasoline to be consumed/wasted. This raises the demand for fuel, which as we have seen, causes the prices to go up even further. It’s an unattractive loop, to be sure. And let’s not forget about the many other negative aspects of getting stuck at traffic signals that won’t change such as irritation; excessive engine temperatures and overheating; frustration; additional green house gas emissions; excessive engine wear; carbon build-up, and so on.
Let’s take a look at how high gas prices are affecting traffic signals. When regular unleaded gas hit $3 per gallon, with spikes as high as $4 in places around the USA, people started buying smaller means of transportation. Motorcycles, mopeds, small cars, and small trucks, with their miserly fuel behaviors, became much more desirable, and much more common on the streets and highways. It’s a logical occurrence. If you own a vehicle that gets 15 miles per gallon, and you trade for one that gets just 18 miles per gallon, you stand to save hundreds of dollars a year on gas spending.
One of the reasons that smaller cars and trucks are so much more fuel efficient is that they use lightweight, high-tech alloys, plastics, and rubbers to construct them. There is no argument that new materials and construction techniques make today’s vehicles eminently better than those of the past – and certainly more fuel efficient. However, the lack of (1)iron in these modern marvels of transportation makes it a real problem to trigger traffic lights. It’s not the lower weight of these vehicles, it’s actually the lack of iron. This makes it easy to see why motorcyclists, bicyclists, and moped riders have always had difficulty when it comes to triggering green lights. But let me explain further…
Since early in the 1960’s, the overwhelming majority of the controlled traffic signals in the United States are regulated by very large, very weak electromagnets. Electromagnets that are used to sense iron, instead of lift it, are called “inductive loops.” These loops most often appear at controlled intersections as large rectangles (outlined in black) in the road.
Inductive loops, like all magnets, detect iron - not aluminum, rubber, plastic, weight, mass, titanium, etc. Small cars and trucks, as well as motorcycles and mopeds, rarely have enough iron close enough to the ground to cause the inductive loop to detect their presence at the intersection – ergo, the light does not trip. Now for the solution to the problem.
Each Signal Sorcerer® traffic light changer (available at www.signalsorcerer.com) generates and directs a very powerful field that causes the traffic signal controlling inductive loops to detect the vehicle it’s attached to, and initiate a signal cycle change. Signal Sorcerer® traffic light changers have been a must-have motorcycle and moped accessory around the world for years, but now that so many small cars and trucks are on the road, they are becoming the new ‘must-have’ accessory for four-wheeled vehicles.
Signal Sorcerer® traffic light changers install in about two minutes, and require no special tools. Everything needed comes with the each traffic light changer. No electricity, no wiring, no maintenance, a lifetime of service, legal everywhere, EPA compliant, DOT compliant, and the internationally famous Iron Horseman Technologies guarantee of your complete satisfaction.
(1) Iron: ferrite, chemical symbol Fe – used in the making of steels. Ferrite used to be a primary component of steels, but now, with newer, more efficient and stronger materials available, ferrite is rather rare.

I have written many articles and the ones about cars are always the most popular. I know why it is and it is because cars are just a lot of fun. Most of my articles have been about older muscle cars and newer muscle cars and which is better and why. One thing I think I can safely say is, whatever generation you prefer it is better than being a “ricer”.
A “ricer” is one of those import cars you see cruising around the city streets lowered down to the point the body is almost scraping on the ground. They usually have huge fart pipe mufflers sticking out from under the rear bumper. I don’t even really understand the point of those mufflers because they don’t even sound good. A “ricer” usually has a driver that has the back of his seat leaning way back but the driver is somehow sitting up to be able to see and reach the steering wheel. Coming from someone that lives using his common sense the whole idea of these “ricers” make no sense to me.
Why spend all this money on a Honda Civic with teal green paint and no power. Why spend even more money to lower it down, throw wheels on it that probably cost more than the car and then try to be cool by sitting straight up while the back of your seat is nowhere near your body?
While old generation muscle car owners and newer generation owners disagree over which cars are superior I think they tend to agree about the fact that their love of their cars actually makes sense compared to the people driving around those “ricers”.
I personally like both generation of cars. I would love a late 60’s or early 70’s Mopar. I would really love a 69 Z28. I have owned several 87 turbo Buicks. I just bought myself an 87 Chevy IROC with a 350 TPI. They all have their great things about them. When I see any of these classics drive by I usually like to get a good look at them. When a “ricer” drives by I find myself chuckling because they just look so ridiculous to me.
I certainly don’t mean to offend anyone who may drive one of these imports. It is your money and you can spend it however you like. I understand the fascination with cars, it is a guy thing. I just don’t understand why it is a Civic or an Accord. This is not to say some imports are not impressive cars. Toyota Supra’s, Nissan 300 ZX twin turbos, and the new 350Z�s are nice cars. They are excellent performers, great looking, and they handle far better than the American cars I mentioned above. One advantage they certainly have over American cars is their reliability.
But, when I think of buying a high performance car to have some fun in it is the American cars they come to mind first. They have power, looks, and an intimidating presence about them. They also tend to be cheaper, unless you get into the real collectible muscle cars. There is just something to pulling up to a friend and hopping on the gas with the right foot and holding the brake pedal with the left and taking off a few miles of rubber. You can’t get the same effect from a front wheel drive 4 cylinder.
