A reusable container to use at restaurants to take leftovers from the restaurant home in. The restaurants could charge a one-time deposit fee for the container that the customer could use each time they visit the participating restaurant(s). This would be an alternative to styrofoam carryout containers, which would reduce the amount of styrofoam carryout containers in landfills. Restaurants could reduce their overhead by not using styrofoam carryout containers, save money and increase...

If we can create huge wind turbines that capture the winds energy for the population then why can we not create a smaller version to attach to our homes? I would rather have a small turbine on my home that would capture and store energy produced by wind than pay an electric company for power. Its cleaner, less expensive, and better for everyone. I think we should spend as much time as it takes to come up with energy saving ideas that depend solely on using our renewable resources such as...

Develop a home recycler which will take all of your recyclable material and crush, grind, reduce, compact and store the material until you are ready to dispose of. I suggest the following criteria: - Items to dispose of - wood, plastic, glass, metals - Must be a system inexpensive enough for the average home - Must be easy to operate and by one person - End product must be ready to dispose of, preferably able to sell the product to local recycling establishment.

The problem to be solved: There are a lot of places where people are supposed not to smoke, e.g. public transportation, McDonalds, cinemas, shopping malls, public toilets, etc. However, there are always smokers they are nuts and do not respect other people's right at all. They simply ignore the rules and keep smoking. For the time being, there is not much we (people don't like passive smoking or don't like the smell) can do. These few culprits smokers can also cause a lot of damages, e.g....

There are many reasons that people pollute so badly but one is sure just lack of perception. Your garbage seems simply to disappear. So, here's the deal. Inside every TV is a mandatory chip that displays an image of the garbage that you produce. At first, it obscures a small part of your TV screen, but over time, more and more is obscured. If you produce less garbage, the TV becomes obscured less quickly. To reduce the garbage, you may perform certain acts such as planting a tree. You...

The air purifier bike concept will let riders clean the air as they ride by filtering out pollutants and creating oxygen. The concept bike will be equipped with an air filter between the handle bars that will screen pollutants and dust and an oxygen-producing "photosynthesis system" that will include a water tank, electric motor and a battery. As the bike is being ridden, air will be forced through the filter and cleaned, allowing fresh air to flow onto the cyclist. The...

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.
