Moon Sensitive Street Lamps Could Save Gigawatts


We don't keep streetlights on when the viagra online france sun is up, so why do we keep them on when the full moon is out? Metropolis Magazine held a Next Generation design contest, looking for designs focused on energy, and the winner was the "lunar resonant streetlamp."

The lamp dims itself depending on how much light the moon is putting out, saving energy and http://cambridgeacademyaz.com/buy-cialis-in-new-zealand providing a consistent amount of levitra and diarrhea light. If the moon is beaming, it'll hold back, but if it is a new moon, or cloudy then the lights will be on full blast  Each lamp contains a photo-cell sensitive enough to detect subtle changes in moonlight. In addition they use LED lights instead of regular bulbs. All together, the lamps use 95% less power than regular streetlamps.  A nation wide switch to these lights would literally save gigawatts.

We can't help but think it would be awesome to have these in our own house. If only our lights knew when they didn't need to be on. I never liked light switches anyway.

And on Motorways?
written by Steve Bailey, May 03, 2007
I think one of the best energy-saving initiatives regarding lighting would be to switch off all street-lighting on http://www.velikibrat.us/soft-tab-levitra motorways (Highways) after a certain time, as they won't be heavily used and it also adds to light pollution. Having street lighting on all night is a relatively recent thing and I'm not sure it's strictly necessary (aside from pedestrian areas, and perhaps accident blackspots).

light-sensors at home would only work in combination with motion-sensors, otherwise they would always be on in the dark even if nobody was there. and light switches will be necessary to turn of the light when you want it to be off (for whatever reason)

as for the levitra cheap fast sensors in streetlights: I love the idea. last night I was trying to go to sleep and the moon was shining into my room and I was surprised at the amount of light it put off! but do the production (and environmental) costs of making and installing all those cells weigh up to the advantages?

"but do the production (and environmental) costs of making and installing all those cells weigh up to the advantages? "

With this idea you really dont need a very large cell at all. You arent trying to generate electricity from moon light, you are only trying to determine if there is cheap viagra moon light. The photovoltaic cells would be smaller than a cell phone and http://medicamentosseguros.com/levitra-femele relatively cheap.

I also like your idea of the motion sensor. I was trying to think of the best way to levitra soft determine if there was a car on the road, but I think that might be the simplest. I was thinking of www.kachinwomen.com either sound detector or IR scanner. If it senses something it will light up the click now canadian healthcare lights for a 1/4 mile or something. We'll let the experts determine the best distance it should be.

lighting designs
written by maxmsf, May 06, 2007
There were a few other submissions to this contest that were also very cool and related to lighting. One was Brightwalk which is a shoe that emits light as the wearer walks/runs, another I liked as PowerLeap which I think is a floor that lights up as people are walking on it.

To be honest

I have no idea why this hasn't already been done.
It's a known fact that a lot of power goes to light at night, and it's not always necessary.
You don't need to be Einstein to think about it..

i agree completly

but my query is when exactly were the light sensitive lamps we have now, were invented?

ideal for street lighting. Is this only a concept or have anyone already implemented ? if yes where can we get those sensors

Nice but more can be done with em

Someone commented on why This has'nt been done before Is cause The electrical components were To big back Then To be used, Now That electrical components have Gotten much smaller and will continue To Get even smaller makes This much more possible, And also was'nt There someThing bout That These street lights could also be charged by The sun and moon or powered by The moon when It's lighted? And another Thing why Is It just street lights and not also security lights?
