Are laser pointers illegal in Western Australia?
As far as I can see there was a movement for them to be outlawed in Western Australia but I'm not sure if it was accepted and that they are now illegal. So If anyone can answer my question I'd be much abliged as I'm looking into buying one. Usually laser pointers with a power < 5mw is less dangerous for human eyes. And the laws in most countries don't forbid 5mw green laser pointers and 5mw red laser pointers. The laser pointers with IR filter is even better. You can choose beamq low power laser pointer.
Why are blue and green lasers illegal?
All lasers are illegal if they are higher than 5mw green and blue lasers are not illegal if they are 5mw or less.
Are burning lasers illegal?
Yes Lasers are illegal because there is a law about it that a kid killed himself and now they are illegal
How much energy do wind turbines create?
Two 5MW offshore wind turbines were built on the DEWI-OCC test field in Cuxhaven, Germany in December 2006.A:Typically a wind turbine will produce between 5 and 8% of what they are rated for on average. Thus a 5 MWh plant should be able to produce 100,000 KWh each hour they are running. Most currently built systems are rated for 1 MWh in the United States so they typically will produce about 20,000 KWh of actual power. Wind systems are rated for average winds of 28 mph. If the average wind is 14 mph, they produce 10% of rated. If wind goes over 31 mph they produce no power and can consume energy to slow the blades. Feathering of blades does asist on reducing these issues, but doesn't eliminate them. A:A wind turbine in optimal winds generates its plate capacity. For example, a typical 3 MW wind turbine will generate 3 MW of electricity. An outdated but still moderately useful rule-of-thumb was that a megawatt would power a thousand homes; consumption is higher now so it's a little less than that, but still, a single 3 megawatt wind turbine will provide power in optimal winds to power close to 3000 homes. Winds vary, however. A typical jurisdiction will see 30% on average of the plate capacity over the course of a year. Some jurisdictions, such as north-eastern Brazil, have excellent winds and see capacity factors of 50%. Wind turbines are very economically viable at 30% capacity factors and become more profitable at higher factors.Except in very low or very high winds, wind turbines will usually be generating some electricity. They aren't just on or off.These factors are taken into account by grid managers when planning and managing new generation, new transmission and operating the grid.Most industrial wind turbines do take about their faceplate capacity from the grid for a few minutes at startup to get the rotors moving. This is trivial in comparison to hours, days or even weeks of continuous generation. In addition, as one wind turbine in a farm comes on line, it provides power to the very local grid to be used by the other wind turbines; the wind farm will typically boot itself up with significantly less than the number of wind turbines times the faceplate capacity from other sources.A:Every wind turbine has a range of wind speeds, typically 30 to 55 mph, in which it will produce at its rated, or maximum, capacity. If the wind is in the ideal range for a 1.5-MW wind turbine, it will produce power at the rate of 1.5 MW, its rated, or maximum, capacity. At slower wind speeds, however, the production falls off dramatically. Industry estimates project an annual output of 30-40%, but real-world experience shows that annual outputs of 15-30% of capacity are typical.
Why can't we put metal in a microwave oven even though the inside of the microwave is all metal?
The magnetron of the microwave is an extremely powerful transmitter of microwaves at the frequency of 2.45GHz. At this frequency fats and water absorb the energy by means of dielectric heating. The metal inside of the microwave oven will not cause problems since it is earthed and act as a shield, it absorbs any electric field continuously over its relatively large and smooth area. Therefore no charge builds up, because it is earthed. It is so effective as a shield, that it would never leak as much as 10W/m2 at 5cm distance. Most manufacturers would specify leakage at 5mW/m2 as maximum while the magnetron inside produce about 800W of radiative power. Other experiments show that it can reduce a RF signal of 2.4GHz with about 100 times. It is usually unearthed metal objects with sharp points thats cause arcing. The object act as an antenna and accumulates an electric charge from the electric field that is perpendicular to the magnetic field of the electromagnetic field transmitted by the magnetron. The electric charge tends to be more concentrated at sharp points without any path to discharge. Once the charge is large enough and the distance between this charge and the grounded shielding is short enough. The breakdown potential of air is bridged which acts in the same way as lightning does. Once the charge accumulate to a potential difference that exceeds 3MV per meter between the object and the earthed shielding, then the air becomes a conductor due to the great amount of electrons stored in the field around the conductive object. Then the charge on the metal object will discharge towards the shielding which is the shortest path to the ground. Once the most of the electric charge is transferred to the earth, the charge becomes significantly less and to little to continue the breakdown condition. The air becomes an insulator again and the spark is gone. This will be the case until the charge is generated again to a voltage of 3MV per meter. This charge and discharge cycle can happen at fast intervals causing a buzzing or arcing sound. The breakdown potential is not only breaking down the air, but it also has to break down through the painted layer in the inside of the shield. It will be the same as with electronic capacitors that blow as the potential passes the breakdown potential, so would the painted layer of the inside of the microwave oven also burn and be seriously damaged. The temperature in the spark can run up to thousands of degrees centigrade. Another problem can be electric current induced and received in thin foil that will cause heating or even fuse or melt. If a CD or DVD is placed into a microwave oven then the metal coating at the rear side of the disk will most likely melt away not because of the arcing as such, but because of high current flow through the thin metal layer which can even melt the plastic. Not all metal objects in a microwave would actually spark. Some objects such as grills that are specially designed for microwave ovens often is designed to be large and smooth surfaces or even earthed. They would actually work in a microwave oven without problems. Whether the object will spark or not, has much to do with the shape, sharp points, clearance, earthed or not etc. Often aluminum containers may work well in a microwave as long as its sides are smooth and do not touch the sides, while a fork will spark like crazy due to the high charge that is concentrated at the tips. This however is not easy to assume for all metal objects whether it will spark or not. In some cases aluminum foil can be used in a microwave to shield of some parts of food that do not need as much heating. The normal foil is thick enough not to heat up from the current. But then again, wrinkled foil can be very unsafe because of its unevenness and its pointy texture. Therefore I would not recommend to experiment with metal objects in a microwave oven. Stick to the manufacturers specifications. It can cause serious damage to your microwave if the experiment would fail. This is also the reason why we shouldn't use cellular phones at gas stations, although the risk is practically very small that the cell phone will cause nearby metal objects to spark and cause the fuel to ignite, it is theoretically possible in some scenarios to happen. However the microwave oven often is about 300 - 3000 times more powerful than a cell phone transmitter section and therefore the effect of a cell phone has on metal objects are significantly less.

Which is better a 5mw green laser pointer or a 5mw blue laser pointer?
Well I wouldn't say either one is better; it depends on what you want: If you want a visible beam / bright laser get the green one. green can do everything a blue can and more if its limited to 5mw but blue is just cool because its blue. its not better its just expensive I perfer green they can be quite cheap for the type of laser on Ebay. Blue always hangs cheapest around 50$ less if your lucky Blue is always expensive I dunno why but its not better if your comparing 5mw to 5mw, not in my opinion at least the green laser is better you can go all the way to 1000mw's witch is powerful don't go to eBay. you can find what you want on this site here ya go. happy hunting laserpointerpro.com have fun you will be on that page for awhile.

Are green lasers illegal in Pennsylvania?
no, most are not however in the united states, any laser over 5mw i believe must be equipped with a safety key. Laws change over time and do not tacky my word as a positive answer however I believe that any laser under 5mw is legal.
