The idea is to use waste bins as mobile power sources, able to power household appliances or party starting speakers and amplifier. The bins will consist of a solar panel, car battery, and inverter. They will be lightweight and mobile, and can be adapted to a variety of uses, and could eventually be used to provide cellular charging stations or sell goods in rural areas.

Oil lamps are still widely used in spite of the fact that they are toxic and not environmentally safe. My idea is to use solar lamps instead of oil lamps. Solar lamps work 6 hours and above; they are available for all people who don't have reliable source of electricity. Solar lamps have changeable solar batteries which are environment-friendly as they are recyclable. Lamps have brightness regulator, they are water- and heat-resistant and can even be used below -4 °F and above 131°F.

Almost everyday I get home and find page after page of ads and coupons in my mailbox. I immediately discard this physical "spam" in the conveniently placed recycle bin, which is full of the same ads that my neighbors in my apartment complex have thrown away. It seems that most people don't even glance at these ads and it is a huge waste of paper (not to mention extremely annoying sifting through to make sure you don't throw any important mail away). I propose initiatives to cut back,...

Create a huge cone shaped Helium balloon with a big funnel like opening in the center. Now place a wind turbine in its center to generate electricity, tie this structure to ground and release it up at a very high altitude to get high-speed winds. Ropes should be tied in such a way that the concave side of the balloon faces the direction of coming wind. The Concave shape will trap more wind and will result in greater efficiency of turbine. At high altitude there is more wind (look at...

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...
