The Robo-Fish is designed for constant monitoring of marine pollution, detecting sources of contamination and relaying the information back to shore for real-time updates. The 1.5 meter device is based upon the hydro-dynamic shape and motions of an actual fish, which allows it to maneuver quickly and easily, even in weedy areas. It can detect contaminants with an array of micro-sensors, and, since it is constantly monitoring the area, send an alert immediately if it detects...

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.

We all have seen the mini-weather stations, but we could add a mini-Richter scale for even more fun, reporting your local area's total over all conditions when you call the reporting stations. This data would be collected and help grow an understanding of future predictions of earth quakes everywhere!

For some time we have had the ability to manufacture huge lenses. We also have computers and software that could make this idea happen. For a prototype, why not construct a large glass lens maybe 12 feet in diameter. Mount it about 30-50 feet above the ground. The base would be round and by computer be able to move round and up and down; tracking the sun 365 days of the year. The intense heat created by this large magnifying glass could be focused on some hybrid turbine and or steam...

Since lightnings create a lot of energy, can't that energy somehow be caught and stored for use?

I think the technology is all out there, I would like to see wave farms trapping air into a piping system with a floating collector which compresses and stores the air to be released into turbines creating electricity. If you had an array of high volume low pressure oscilating collectors forcing the air into pipes that bubble up into the floating collector where it is pressuized you can have 24/7 non polluting electricity.

As trees are one of the most efficient "carbon-storers", lowering the emission of greenhouse gases into the atmosphere, and thereby helping to prevent a global climate catastrophe, federal, state and local governments should give tax breaks to those who either plant and/or conserve trees on their properties. This could come in the form of reduced taxes; perhaps a reduced property tax for homeowners whose property has a certain minimum density of trees per 1/4 acre, and reduced taxes...

I moved to the city a couple of years ago, and have noticed how clean the roofs always are. No leafs get up there. Further, from every roof there runs a pipe all the way along the edges of the roof, and to the ground in order to make the rain that ends on the roof go to the ground without pouring down on the windows. My idea is simply to put a little mill inside the pipes that go from the roof to the ground, the mill should run a simple generator in order to produce power. - Since the...

I have an idea about pollution that may really stop industries and the gov't from dumping trash in our backyards! There are countless examples of companies dumping their trash, usually on the poor side of town. I think that all companies and individuals should be ranked by how much trash/waste they produce. This could be done by producing trash cans & dumpsters with sensors that count the amount of mass in the container per week. For liquid waste (which many companies dump liberally...

Like any smokeless cigarette you need only slip your standard cigar or cigarette inside a tube with screens at both ends and one end you light while the other snaps shut for inhaling and could come with an optional filtration system to further make a "So called" safer smoke!
