Solar Energy Booming in China

The city of Beijing, China’s second-largest energy consumer, has announced plans to build a “solar street” where buildings, streetlights, and other features will run entirely on energy from the sun. A second pilot project in the city’s Xuanwu Park will introduce solar power for lighting, heating, and refrigeration. .

In a move to cut domestic reliance on coal and oil, the Chinese parliament passed a historic law in February pledging to use renewable energy resources for 10 percent of China’s energy consumption by 2020. The new law includes details on the purchase and use of solar photovoltaics (PV), solar water heating, and renewable energy fuels. In particular, the government will promote the use of solar PV in b

China will bury the earth in waste and its OK because its not the US

I was checking in internet about revenue business,I found the following information.

Silicon energy business

Silicon manufactures and distributes a large selection of residential solar panels, solar cells, lights, fountains, and hot water systems

founder in 2003

Revenue 2005: $1.1 million

Revenue 2008: $5.4million

employees: 35

growth: 390.2%

type:Energy

now is it possible to get those number in real life? with 35 employees got $5.4million? depend of the business but if everything track well is it possible? I found in inc 500 it;s supposed real business.what’s your opinion
ubicated in united states

In an IT biz, absolutely positively possible!

So you don’t have to worry about running out of gas, how about a jet ski motor ran by the suns light. That would be kick butt to travel the oceans around the world by jet ski. You could wear a back pack with C- rations food and salt tablets to drink water plus a 1/5 of everclear when I relax on an inner tube to sleep on the water. To prevent a shark attack, my inner tube will have a fold out cage to be around it. The jet ski will be larger than most with space for the inner tube cage. How about it? Think I could get a patent? I’d sell em for $8000. 8000 miles diameter of earth and my wee wee.

Interesting thought experiment!

On the patent, you can get a patent on just about anything if you just keep narrowing down the claims. However, I would have concerns about the value of the invention.

Some things to think about:

- In a recent Reader’s Digest, two women tried to row across the Atlantic in a specially-designed boat. They failed. The open ocean is nothing to be trifled with. What would a jet ski do in a storm with 30-foot waves?

- To push a bicycle at 10 MPH, you need maybe 100-200 watts. That’s a panel maybe 10-15 square feet. You would have to tow it on a trailer. And the bike is frictionless compared to a jet ski in water. I think it would end up being more of a solar barge – big, flat, not very fast.

I am building an energy efficient house. I’m installing solar panels for water heating, and aerothermic underfloor heating, as well as extra good insulation. I’m now thinking about lighting. Can anyone advise me about the comparative efficiencies of halogen v other light bulbs? The house should benefit from plenty natural light as there are large glass windows.

If you are building right now, look at T5 or T8 fluorescent lamps. The T simply refers tot he diameter of the tube. A T12 is 1" in diameter and a T8 is 8/12 or 2/3" in diameter. If you need point lighting, consider LED’s. Understand though that many of these are monochromatic – they only give off one color. A few LED’s now are polychromatic and produce a more natural color or light. You’ll have to hunt for them though. If you can wait just a while longer organic LED’s or OLEDs will be showing up soon. SOme of these are truely organic but this family of lights is carbon based.

You also mentioned large windows. You will be better served to have your contractor install light shelves. You have probably seen the glare that can come from the sun shining directly in a large window. It makes the rest of the room look dull. A light shelf eliminates this problem. A light shelf lets sunlight come in an upper window that is not directly visible from the floor. Instead the light bounces off of a shelf and upper walls of that room for just a few feet. Then the shelf ends and the light is now diffuse enough that it lights all parts of your room equally.

Sky lights with short tunnels in your ceilings work much the same way. You can also add light tubes to your house. These light tubes collect sunlight from your roof just like a sky light. That light though is trapped inside a shiny metal tube. You can extend these tubes all the way down to a basement if you want. A diffuser on the end of the tube glows just like an electric lamp when the sun is shining.

I would not consider halogen or other types of lamps. Many of them are not made for residential use. When they are, the quality of light is often poor. Look underneath a halogen or a mercury vapor lamp and yu’ll see the color distortion.

For instance, if we built homes with solar panels to turn light into electricity, an we do this on a large scale, what effect does that have on the environment that normally would absorb that energy?

Actually, it supon us to judge whether the energy used up is taken as GOOD or WASTED…
but our (humans) point electric energy is not considered as harmfull…<for more clarification contact me>

And then call it Arctic City and break the record for the largest population center north of the Arctic Circle?

And have it look like a HUGE Las Vegas, only with Polar Bears sharing the streets and LOTS of beers? And make a metro transit underground system made out of ice?

And use artificial solar light technology to make it daylight in winter.

To build a big city you need a big population or a lot of money or both.
If you want an alternative to Las Vegas, go to Dubai, its like Vegas on steriods with none of the sleaze.
There would also be concerns about the cost to the environment, it costs a lot to keep people warm in the arctic, and transport costs to get food and supplies to the city.
canada is also experiencing a labour shortage so they don’t have the workforce to construct this city.

I have four large sealed led solar batteries I use for lighting. I have a backup charger to keep them filled, but one night I left it on all night and forgot and the next morning they were warm not hot and bubbling. The reading said 15v so did I damage them or will they be ok? they still read 12v at this time.

they should be ok the excess charge only lasts till the batteries cool down you do need to put a charge limiter on the charger to prevent overchargeing the could blow up. the limiter detects the full charge and stops putting more in. it should be built into your charger if not get one or build one. your life will be easier.

I have done some research but am somewhat clueless. I was checking out solar floodlights and see that they tend to be 10 to 20 watts Quartz lights. That sounds like it could not light up a small bathroom. let alone a backyard?!? I have a large size backyard and want to put 2 sensored floodlights back there. I want to have decent lighting and keep the electric bill from skyrocketing. Can solar floodlights light well? Should I go with a halogen? Help please.

I would put halogens and use the 500 watt bulbs they will light your backyard up like day light. But they should be able to be switched off. The reason is if you are relaxing outside at night you don’t want them going off. Word of advice the more expensive fixtures are better. The one I got at Home Depot were $79 but there warrantied for life and heavy duty.

We are renting a 1400 sqft home built in the 1950′s. I want to be as energy conscious as possible, but it seems impossible in this old house that was built long before anyone even thought about conserving energy. I know we can seal the windows, we’ve already replaced all light bulbs with CFL’s. We don’t have the money for large solar panels and even then we can install anything because we are just renting. Are there any portable solar panels that we can put in the backyard or something? Any advice on how to conserve energy would be great!

you could use solar panels but their all expensive. houses in the 50′s were not built that great so before you deal with the electricity I would deal with the insulation and window issue. A lot of houses from that period would use sawdust for insulation. work on sealing everything in the house and then go on to electricity
