Energy Conservation - Parking Lots Printer Friendly Version
Have you ever seen the city lights at night ... noise pollution right? Well what about all the costs associated with those lights? Think of all those huge parking lots that have giant lights glowing all night long ... why? Now the facility owners and management will tell you it's about security, which is vaguely reasonable. However, they only need to be on when someone is there.
IDEA: Add motion sensors to all those light poles so that when someone moves in the area at night, the lights come on, but otherwise it is peacefully dark and quiet. Given the spacing of these poles typically should create a "grid" that would light an area with any activity - security maintained. Plus the cost savings from electrical conservation.
Reward: Credit for expressing the idea.

Highway power Printer Friendly Version
The wind off of cars on the highway should be able to be harnessed in a positive manner. Why couldn't we put wind turbines down the middle of the highway so that air generated from passing vehicles could in turn power something such as the highway lights?

Algae for Life Printer Friendly Version
There's many people that think CO2 is bad, but what they don't know is that there are things in nature that have to have CO2 to survive. Did you know that algae consumes more CO2 than trees and the toxins let off by coal burning factories are nutrients to some algae's? The nutrients that the algae then produces can fight and prevent malnutrition and when dried, the algae becomes biomass and can be burned like coal for energy with no emissions. I propose that all coal burning factories, by law, should have to implement this concept to their industry.
