Does Anyone Know Anything About the Very Large Dragon Street Lamp in Venice Italy?
got it! it is in Rialto at a corner of a shop (it should sell leather accessories such as purses, belts and bags). It is at the entrance of "Mercerie" the street (calle) that leads you to from Rialto to Saint Mark's. In particular it is in Campo San Salvador where a pillar stands (in memory of a historic event occurred when Venetians were under the Austrians -between 1814 and 1866).1. The wavelength of the blue light given off by a mercury vapor street lamp is 436 nm.?E = h c / wavelength h is Planck's consistent, c is the speed of light in m/s and wavelength could be expressed in meters The E that you calculate is in accordance to photon. So multiply the ensuing volume by technique of Avogadro's volume, and also you are performed2. would You rather be a Street-LAMP or a LAMP-Shade?I would rather be a Lamp Shade, because I would be much safer, than in a Street Lamp3. would You rather be a Street-LAMP or a LAMP-Shade?A street lamp. It's more use in times of need - and it sees more of life4. How much electricity does a street lamp use?This varies greatly. A commonly used lamp is low pressure sodium (the very yellow ones). This would likely be 90w (but there are bigger and smaller) so 0.09 X 24 = about 2 kWH per day. The brighter yellow ones are high pressure sodium and would likely be about 150w (again there are bigger so maybe 250w or 400w). The newer white ones are metal halide and probably about the same power as a high pressure sodium with better light. You may find the odd mercury vapor light (white) in older fittings. So, no real answer unless you know the type of fitting.5.

Outdoor Solar Lights Are Not Working?
yes first you checked that whether you put batteries correctly or not1. solar storms pose a threat to electric grid?The massive magnetic flux acting on a wire induces a current, which, if not shielded against, can cause considerable damage. I am informed that a huge solar storm in the 1800s, before we had an electricity grid, caused sparks to be emitted from circuits which were not even connected, giving electrical shocks to telegraph operators. If this happened to nuclear reactors, it would stop the pumps cooling them, causing disasters on the scale of Fukushima no. 4. solar storms news and articles - Natural News Mar 20, 2012 ... solar storms news and articles. ... Solar storms could bring down modern civilization.2. Why is solar insolation so important?'Solar insolation' is redundant b/c the word 'insolation' is derived from the phrase 'INcoming SOLA radiaTION.' The sun's energy drives the weather...the ocean currents...flora...and fauna. Insolation is so important b/c without it... life on this we know it...would not exist.3. Invalidation of the Solar Nebula Theory?No, it does not , but it does suggest something that had not previously been considered: it's possible for Jovian planets to migrate inwards from where they were originally formed4. what are the different types of solar power?i do not know i did not even know there were different types of solar. or are you just playing with me?5. How can I calculate the rate of power consumption of a solar car along a known route with changes in elevation?Not sure if this approach is in the format you need, but it might help. The work required to go uphill by a height $y$ is$$W=mgy$$where $m$ is mass and $g$ is gravitational acceleration. Assuming mass and gravity are constant, we can differentiate this equation with respect to time to get:$$dotW=mg fracdydt$$we can also use the chain rule to rewrite it as$$dotW=mg fracdydx fracdxdt$$in which $x$ is the horizontal distance traveled. Then, $fracdxdt$ is just velocity, so the equation reduces to $$dotW=mgv fracdydx$$You already have the data for $fracdydx$, so you can factor out the velocity and insert this equation into your first equation for total power consumption:$$P_w = (F_air F_roll mg fracdydx ) cdot v $$6. Is A Solar Dyson Sphere Habitable?I am not a big fan of the spheres and I have no solution for the gravity issue, but I will make a fake answer to make some points about the energy issues that are really bit too long to be comments.Can be anything you want within upper and lower bounds set by engineering and the total energy of the star. There are lots more variables than trivial models assume since the structure of the sphere is realistically more complex. There is no one-to-one connection to the temperature of the inner shell. You can use insulation to make the outer shell cooler than the inner shell. You can use heat pumps powered by photoelectrics to make it hotter. Or more robustly simply connect it to hot areas of the inner shell. Yes, I said hot areas, there is no reason why areas of the inner shell must all have the same temperature. You can give different areas different albedo. Or simply link different areas on the inner surface to areas of variable size on the outer surface. If areas A and B on the inner surface have the same area but the outer shell radiator A is connected to has ten times the area of the radiator B is connected to, A will be cooler. The sphere is not, cannot be, made from homogeneous mass, it has structure. Since the temperatures of inner and outer shell are not directly linked, you can use insulation to make the sphere habitable at a distance higher than usual or cooling to make it habitable closer. So you do not need to worry about what the insolation or habitability of a planet at that radius would be. For example if the sphere is larger, you can replace parts of the inner surface with mirrors reflecting light to the inhabited parts. If smaller you might give the inhabited parts higher albedo, so that radiation is reflected to the uninhabited parts.There is no known way to get a comfortable gravity to the inner (or outer) surface. Nor should there be. a Dyson sphere is not a habitat, it is an energy collector. You should build your spin gravity habitats separately and just use the power collected by the sphere to power them. Or just use planets. Technology needed for a Dyson sphere should allow building planets. And the mass needed would allow building lots of them. Just because having six planets on the same orbit is not stable, does not mean you can not make it so. It would be easier than building a Dyson sphere. And making the planets habitable would be much easier. Like I said in the beginning this was not really an attempt to give an answer. Just some comments too long to fit into actual comments. You should not expect any of what I said to be true or accurate. Just some food for thought.

Ok, Let Me Make It Clearer, What Light Can You Use to Charge Solar Lights? Besides the Sun.?
The key thing is blast as many watts at the solar cells as you can. The colour you want varies with the type of solar cell, with maximum sensitivity ranging from infrared to ultraviolet. Many solar cells are most sensitive to blue light. Would it not be easier to hotwire the lights for an external charger? I know it's not what you asked, but it's what I would do.1. Any solar lights give off yellow light?Hi. Yes. Many have a yellow LED. We have a dozen in our yard purchased from Walmart2. Do solar lights for the outside home really work and do they last?Solar lights work fine. Mine, from Walmart, are 3 years old and still going. BUT solar is not for you. They do not give off anywhere near enough lighting for your purpose. They are decoration only. You need wired lighting.3. How long do solar lights stay on?It depends on the type of lights you have. Accent lights will stay on all night with a few hours of sun, and often into the next cloudy/rainy night if the battery has stored sun. Lamps and Lamp posts are the same thing. You want to make sure you get good ones though, and look for ones with Lithium-Ion batteries. There are also decorative lights that stay on, such as lanterns or floating lights for pools. And floodlights/security spot lights that can stay on up to 2 minutes every time the go on for up to 100 times a night, or for up to 8-10 hours continuously.4. Solar pergolas, gazebos & patio covers: A quick guideWhen you think of solar power for the home, solar panels on the roof is what immediately comes to mind. But there are many other places you can put your panels to produce solar energy for your home. Some of the more popular alternatives available in 2021 are ground-mounted solar panels and solar carports. Another approach is to go for solar structures on the patio or in the garden, which are often referred to as 'solar pergolas' or 'solar gazebos.' Read on to learn exactly what solar pergolas and solar gazebos are and whether they make sense for you. What are solar pergolas, solar gazebos, and solar patio covers? They all refer to solar-energy producing structures built on your outdoor patio or backyard. They can be built upon existing structures on your property, or be custom-built with solar energy production in mind. You could use a small structure if you are just looking for enough energy to power outdoor lighting. But with a bigger setup, you could place enough solar panels for a 5 kW solar system or even a 10 kW solar system. A system of that size is usually enough to power your house as well as sell excess electricity back to the grid. Are solar lights and solar umbrellas different from solar pergolas, solar gazebos and solar patio covers? Yes, they are. You have probably seen solar lights and solar umbrellas, which are popular in people's backyards these days. Solar lights are smaller devices that use solar cells, which are either built-in or attached as a small accompanying unit. The cells charge an internal battery during the day and then power lights at night. There are many different types: solar path lights, solar spotlights, solar ambient lights, etc. Solar umbrellas, meanwhile, are patio umbrellas with inbuilt solar cells that power attached lights and sometimes even a USB charging station. Solar lights and solar umbrellas have limited power-producing capacity are not built-up structures like solar pergolas, gazebos and patio covers. Which is better? Rooftop solar vs. solar pergolas, gazebos and patio covers For most houses, the rooftop is the place with maximum surface area and highest exposure to the sun. It is usually also convenient to mount solar panels there, as minimal construction or modification is required. These factors are why roof-mounted solar panels have remained the most popular option for homeowners. However, in many instances, your roof might not the right place to put your panels. Here are some of them: Space constraints: Your roof does not have space for the number of solar panels your require. (Not what this figure is? Calculate the sq. ft. required for solar panels here). Shade: Obstructions like surrounding buildings or trees might block direct sunlight from hitting your roof. Unfavorable angle or positioning: You will not produce maximum power unless your roof faces south. The roof angle, or pitch, also needs to be at the right level (30 to 45 degrees) to work best. Aesthetics: Maybe you just do not like the way they would look on top of your house... Ground-mounted solar panels are one alternative to consider. But they have one big disadvantage: they require substantial amounts of real estate, space that you can not use for anything else. This is where the solar pergola, solar gazebo or solar patio cover-as well as the solar carport- enter the picture. They are all dual-use structures, so they are more space efficient than a ground-mounted setup. You might already have one of these structures out back, which you might easily be able to adapt or modify to hold solar panels. Otherwise, if you are building one of these structures from ground-up, you can go for a designed-for-purpose structure that looks looks great and is optimized for maximum solar energy production. Of course, opting for a whole new structure means adding construction costs to the cost of solar panels. Solar pergolas, gazebos, and patio covers are just one of the routes you can take to go solar. If you can not or do not want to put solar panels on your roof, you could use them in order to gain all the benefits from going solar. To see if they are right for you, find a local solar installer who can assess your property and provide recommendations.
Low Voltage Solar Lighting Has a Bright Future with ...
In today's day and age, one of the important things that people are starting to recognize is the idea of energy efficiency. More and more appliances, vehicles, household items, etc. are touting the label of being energy efficient. This benefits not only the owner of the appliances, but the world as a whole. Therefore, companies such as have begun to offer a wide range of landscape lighting options that are low voltage and/or solar powered. These lights can offer both plenty of illumination for any given area as well as the freedom to be without wires and the ability to save money. Furthermore, there many of the solar powered lights that are offered by have LED bulbs which, in turn, use far less energy than is normally consumed by traditional has solar lights that come in a variety of shapes and sizes. They are very attractive and can match with any style of outdoor décor. There are some that are lamppost style while others are cap lights that can be mounted to fence posts, guard rails, etc. These options allow the solar panels to receive plenty of light in order to charge the batteries for use during the nighttime hours. With the increase of technology in recent years, solar landscape lights that are offered by can last all night with the charge that is accumulated throughout the day. This is a vast improvement from some of the first solar lights that would only last a few hours at the most.One of the things that people may scoff at when looking at the solar landscape lights from is the initial price. The solar lights range in price from about $180 to $360 depending upon the model. However, when the cost of powering the light is taken into account, the price becomes much more attractive. This is because solar lights require no further investment after their initial purchase. There is nothing to pay for other than the light itself. It is also useful in the fact that there are no wires that run the risk of being damaged and must then be replaced.That leads to another benefit of solar powered landscape lighting. Since they are totally independent of any outside power sources, the setup and installation is incredibly easy. The only thing that must be ensured is that the light is located in an area where it can receive plenty of sunlight throughout the day. If the style that is purchased is a cap light, it should be mounted securely to whatever it is placed upon. However, there are no wires or batteries that need to be plugged in. This means that the owner is at liberty to place the lights wherever it is desired. This freedom of location is one of the biggest benefits to using solar powered landscape lighting.While they may initially cost more than a traditional light, there are many benefits to having solar powered landscape lights that can surpass the cost. USALight has several attractive options available for those who want to use solar power for their landscape lighting needs.
Would You Rather Be a Street-LAMP Or a LAMP-Shade?
neither...I AM a disco strobe light! Ill make you all epileptic =)1. A street lamp weighs 150 N. It is supported by two wires that form an angle of 120 degrees with each other..?Any system...let me repeat...any system that is not accelerating (or decelerating) has balanced forces acting on it so that the net force (f) is exactly zero. This results because f = ma = 0 if and only if a = 0 for a mass m. OK your weight W = 150 N is not accelerating, in fact it is static; so there is no motion whatsoever. So f = 0 = ma for the system, which includes the weight and the two wires. This means that something is canceling out the weight because f = ma = W - F = 0; where F is that "something" canceling the weight (W). The only "something" you've defined for your system is the forces pulling up by the attached wires. Since there are two wires, each one has a share of that upward force. By "upward" we mean vertical force acting in a direction opposite of the weight (W). As there are 120 deg between the two wires, the vertical force for both wires is W cos(60) = Fv and for each individual wire, it's Fv/2 = (W/2) cos(60). Similarly, the horizontal force on each wire is Fh = (W/2) sin(60). Since the vertical and horizontal forces form a right angle for each wire, the force along each wire, the tension, is T = sqrt(Fv^2 Fh^2). And, by substitution, T = sqrt((W/2)^2 cos(60)^2 (W/2)^2 sin(60)^2) = sqrt[(W/2)^2 [sin(60)^2 cos(60)^] = sqrt((W/2)^2) = W/2. a. Thus, the tension (T) in each wire is one half the weight of the street lamp = W/2. b. Following the same line or reasoning used to find the tension at 120 deg, we see that the angle makes no difference because sin(deg)^2 con(deg)^2 = 1.0 no matter what deg is. Tension, therefore, will still be W/2 in each wire with 90 deg between them. The important thing to remember is that, if the system is not accelerating or decelerating, the net force on it is zero. So all the forces acting on it will cancel out.2. The ‘Street lamp charger' is coming - BenderThe concept, of charging electric cars directly off roadside lighting (street lamps), is as simple as it is smart. Requests for the street lamp variant of the 'Berlin' charging point are coming in thick and fast. "The integration of power sockets in existing infrastructure like street lamps [...]" is a "[...] fundamentally available technical solution". This prompts the authors of Germany's nationwide call for financial funding to set up a charging infrastructure as part of the 'Immediate Clean Air Programme 2017 to 2020' [Sofortprogramm Saubere Luft 2017 bis on 4 January this year. The Ministry employees are also thinking along the right lines with their depiction of 'Street lamp charging' as a low-cost charging infrastructure, and they further reason: "At present, affordable charging facilities are absent in many applications, at places where people park for extended periods and could charge their vehicles, for example overnight. This prevents those affected from being able to consider electric vehicles as a genuine alternative form of mobility. One example of this would be users who either do not have access to a fixed parking space or who are not able to equip the one they have with a charging point". The Berlin start-up and partner of Bender GmbH & Co. KG, ebee smart technologies GmbH, would have to formulate its founding myth in a similar way. In fact, the vision right from day one of this manufacturer of charging infrastructure, founded back in 2011, was to use the electrical infrastructure already in the public domain for the charging of electric vehicles. What has emerged from this is the 'Berlin' charging point, developed and sold by ebee. Its slimline hardware enables it to be fitted to street lamps quickly and easily, as well as to walls, pillars or to 'urban furniture'.3. The wavelength of the blue light given off by a mercury vapor street lamp is 436 nm. What is the frequency of?E = h c / wavelength h is Planck's consistent, c is the speed of sunshine in m/s and wavelength will be expressed in meters The E that you calculate is in accordance to photon. So multiply the consequent quantity by technique of technique of Avogadro's quantity, and also you are finished
