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...

I had this idea for a few years and just want to put it out there. There are hepa air filters in homes that are ionic and clean pollutants in the air. So why can't we build one big ionic hepa filter for the air pollution we already have. We can also reuse the oils that are captured as another way conserving. Also if this is too much money maybe we can create smaller versions and put it in the exhaust of our cars. If it works in our home why not in the open air.

Large windfarms generally take up a lot of land and that space on the turbine blades or the top of the generator house retrofitted with flexable solar cells could easily increase the amount of power produced without taking up any more land. Anyone else have any other ideas on increasing the renewable power production on current power installations shout it out.

What happens to the millions of little hotel soaps that are only used once or twice? They are thrown away. Why isn't there a central collection agency that gathers all of the soaps, recycles them into new soaps or distributes them to people in need? The hotels could donate the soaps to the agency, and therefore get a charitable tax break. If the hotel wanted to buy back new (recycled) soaps imprinted with a logo or something fancy, they could pay extra (also to charity).

My idea for state and federal air quality bureaus to get better control of the air quality in their locales would be an engine and transmission replacement program for older vehicles. Many of these vehicles are owned by low and middle income drivers, who cannot afford newer and less polluting autos; replacing the engines of these autos would be an economical way to keep air quality from deteriorating. One suggestion is to provide a certain percentage to car owners, such as 75% of the costs...

Not your normal umbrella, the sensing umbrella will respond to the level of air pollution in the area with a series of LED lights while helping track air quality. The Arduino-equipped sensing umbrella will be able to gather pollution data and upload it to pollution databases, making it possible to generate local pollution indicator maps for smaller regions. The umbrella's LED lights will also provide a more immediate source of information as they will flash and change color...

Although I'm a true fan of recycling, I hate glass containers. There's one in my back yard, and every time someone throws in a bottle, I can hear it in my entire flat. Even worse, there's a bar on the same block where I live, and every morning they dump last night's bottles into the container, I simply fall out of bed. I've spoken to the local trash authorities about this problem, but they say they have experimented with silent glass containers in the past, and that it can't be done. I...

Take advantage of excess electrical production capacity during night-time hours by equipping homes and businesses with large battery systems. This approach has been suggested for electrical cars where the disadvantage is the size of the battery system, but this would be much less of an issue for homes and businesses. Power companies would need to provide a cost incentive to encourage the use of these and the energy storage mode would be best controlled remotely by centralized operation at...

The reservoir in your toilet is much too large for the quantity of water needed to flush out the contents after use. Suppose if everybody put a red brick in the bottom of their reservoir how much water that would save!

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...
