Do/will You Go by the Porch/street Light Rule for Your Kids?

I had never heard of this rule, but it sounds like something I will use with my daughter

Do/will You Go by the Porch/street Light Rule for Your Kids? 1

1. Is there a drop-in LED replacement bulb for a high pressure sodium street light?

You can probably ask the people down at you local hardware store or Home Depot for ideas, but I am assuming that what you are asking for does not exist, as it would probably be cheaper and less complicated to simply replace the entire light fixture than it would be to design a retro fitted LED bulb for every application. ===edit==- Is not the high pressure sodium bulb more energy efficient that an LED light anyway? I am just wondering why (other than the ugly, unnatural color) you would want to replace it anyway.

2. How do you make a street light turn green after it's been red for 20 minutes?

I usually stare at the light with one eye shut and give it the finger. It does not change any faster but it feels like it does

3. What to do when jogging and stopped at a street light?

keep jogging.. forget about the lights, pretend you do not see them, or maybe you can jog fast enough not to get hit by a car

4. When you were a kid did you often break the street light rule?

Well, it comes to a point where even though someone is breaking the law you still do not have the right to kill them if they have no intent of killing you first. Bad driving does not make an excuse for you to drive even worse. You have the responsibility to avoid an accident whenever possible, not just gun it and hope the other side does not die as a result. It could be your own death too. If police wo not keep order then perhaps it's time to grab attention in other ways. Put the camera in your car, but do not go out of your way to hit others. Vigilantism is going to only land you in jail, but do what you want. You can make videos and make sure people who can make a difference do see them. I fully understand your frustrations. I live in the Dallas area where people drive like lunatics and i get so mad, but I am not going to put my own life in even further jeopardy by going to extremes and ignoring others faults and arrogance in the name of taking law into my own hands. I go nuts when I hve to wait in line like everyone else in traffic then some clown decides to drive all the way around everyone in the curb lanes then expect everyone to just stop and let them in. The maddening part is they always do! It's the only time I tailgate to keep them from getting in front and I've gone as far as driving in both lanes half way into the curb and half way in the lane to keep them from cutting, but I wo not gun it to keep them from doing so. I wo not endanger them or others to make a statement. You could move even though you do not feel you should have to, but if nothing is done you might have to. Hitting others or simply ignoring the obvious will eventually get you killed

5. i hate the street light?

nicely, in specific circumstances it purely is going off by means of itself yet different circumstances whilst your making a astonishing turn and u DONT provide up, then u get referred to.. yet u did provide up so as this is rather weird and wonderful why it would nevertheless take your image. yet dont project, i dont think of it gets a value tag.

6. why does the street light in front of my house keep turning on and off every few minutes?

it is a new light ive changed it and it still keeps going off and on

7. How does the stop and go street light know when a car is waiting?

Some just change on the basis of the current time. Some have pressure sensors under the road. It can be really annoying if you are waiting for the light to change, but you have not triggered the pressure sensor.

Street lamp is a necessary part of every part of the street, with a primary function is to provide comfort to the driver and pedestrian. Street lamp also has a security function that is to prevent accidents and criminality. On the other hand, from environmental and economical perspectives, solar street lamp is better than the traditional street lamp, since the traditional technology uses far more energy during its operational life [1], [2].Solar street lamp is a lamp that utilizes solar cell to obtain electrical energy during the daylight hour by solar radiation and then stored in the battery [3], [4]. At night, the energy saved in the battery is used to provide light on the street. Generally, there are two types of solar street lamps: (a) unintegrated lamp; (b) fully-integrated lamp, as shown in Figure 1. Unintegrated lamp is a lamp which are each component, i.e. lamp, solar cell, controller, and battery, separate from each other, as shown in Figure 1(a). However, the lack of this type of solar street lamp is in need of a complicated installation. Different from un-integrated lamp, fully-integrated lamp has integrated all the components of each lamp, as shown in Figure 1(b). The fully integrated lamp causes easier installation, although the component price of this type is expensive [5].Semi-integrated lamp (Figure 1c) tries to overcome both problems that is expensive and complicated installation. Semi-integrated solar street lamp only integrated solar cell, controller, and battery, while lamp is separated using cable. This configuration makes semi integrated lamp cheaper and easier for installation that is suitable for rural area.Why arenu2019t solar cells used much in producing voltage?The current delivering capacity is the issue. Combination of the good quality cells could probably deliver the high currents required, but setting a solar plant may cost more than the conventional plants.However, solar cells are used in low current circuits quite many panels of solar cells i need to produce enough electricity for running a house's devises and machinesIt depends on what you want to run. There are systems out there that will run your entire house "off the grid" with very few panels. In this situation you can have as few as one panel up to 3 or 4 to run the whole house. Then there are panels that will only run things like a small appliance or cell charger. It really depends on your needs and your budget. The bigger and more expensive the systemWhat happens to solar cells in water (or in anything other than air)?This causes a drop in efficiency. For single junction cells, which are very tolerant to changes in spectrum, the drop will be much less than for multi junction solar cells which are designed for particular spectral conditions.The IV characteristic will change because the surface resistance will decrease causing a leak current. This will also reduce efficient.Reflection occurs at the interface between materials of different refractive index. Semiconductor have a high index, say around 3.5, so the reflection is high. For these reasons solar cells have surface antireflection treatment which tries to place a materials of intermediate index between the surface and air (#1). If you place this in water you will skew this behaviour away from the design specification. (#1) the details here are quite fascinating, I slightly over simplified this pointWhat is the cost of solar cells compared to the cost of fossil fuels?That's a very complex question, and somewhat of a moving target. Solar cells are getting cheaper. However, it's not really a direct comparison. If I buy a solar cell, it produces a kilowatt hour, continuously -- as long as the somewhat less. If I dig a gallon of oil out of the ground, refine it (which takes energy), it's use up. I think the best comparison would be to take the expected lifespan of a solar cell and calculate the cost of a kilowatt hour, including the cost of the solar panels, installation, etc., etc. my guess is that the solar panels would be much cheaper.besides batteries or solar cells or fuel cells, or generators what else is there that can produce high voltageYou are correct a nuclear power plant = a coal powered power plant with the boiler replaced by a nuclear reactor. Yes we can create electricity through other means, but we can not do it without electrons. A thermocouple can also be added to generate electricity by inserting two dissimilar metals in the reactor pool, but that would just create more radioactive elements to mess around with. A fusion reactor will probably be used to boil water to turn a generator as well. Electrons are the source of electricity without an electron there is no electricity. So you can not create electricity that way. A nuclear reaction passes neutrons around and creates neutron radiation; the electrons and protons are not altered or affected in any way. Instead they reform smaller radioactive elements through the process of atomic decay. A generator spins a coil of wire in a magnetic field to create electricity and beyond chemical reactions (batteries) and solar cells we do not know of any way to create electricity. Is there another source of high voltage; yes, lightning. Lightning is static electricity created by the clouds moving across the earth. It is the same force that creates a spark when you rub your feet on a shag carpet and touch a door knob. If you run a huge thermocouple into the volcanic earth and then cool the other ends in the artic atmosphere then you can create electricity, but the people in Iceland prefer to use the steam created to run conventional generators; they get more power that way.
