In-case you didnt know, Earth Hour 2010 was on 27th March, 8:30pm. Everywhere around the world, according to their local time, people switch off the lights for 1 hour. 🙂
Toggle on over to Boston.com ‘s Big Picture to see these fascinating switch off the lights. Click on the photos to see the fade out, switch off lights effects. 🙂
Do you know…
1 recycled plastic bottle saves enough energy to light a 60W bulb for 6 hours
And a 22-watt fluorescent light bulb emits the same brightness as a 100-watt incandescent light bulb.
In the 1870’s, Thomas Edison used carbonized bamboo fibre as filament in the development of the light bulb. The carbonized filament he used then still works and is on display at the Smithosionan in Washington D.C.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
Combining metal with acid (like lemon juice) causes a chemical reaction that creates positive and negative particles around each piece of metal. The negative particles will move through the wires from one piece of metal to the other, which causes an electric current. If the reaction is strong enough, it can even power a light bulb!
