The idea is to launch floating islands in lakes in an effort to improve water conditions and restore natural habitats. The islands will be made up of non-toxic recycled plastics injected with an inert polyurethane foam for buoyancy, and will act as floating treatment wetlands. The islands will mimic a concentrated wetland, eliminating algae blooms and problematic nutrients while encouraging bird and insect populations.

A solar paint can be made in large enough quantities to be eventually used as an alternative to silicon-based solar cells. The paint is made up of titanium dioxide particles coated with either cadmium sulfide or cadmium selenide. The coated TiO2 particles were suspended in an alcohol-water mixture to create a paste that created electricity when it was applied to a transparent conducting material and exposed to light.

A new bicycle made out of folded sheet metal will be stronger, lighter, and cheaper to produce than the conventional bike frame, and it will be folded by hand. The bicycle frame will be based on a patented system, which will include a method of cutting perforations into pieces of sheet metal and will allow the metal to be folded by hand. The folded sheets will then be riveted or glued together to from the desired object.

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...

We should be able to creat ultra light sound proofiing material by now, incredibly thin but able to dampen sound waves.

Why not use the single celled algae to experiment with extracting lipids from it and using the lipids to make biodiesel. Because algae grows very quickly and does not require much land, it can provide a more continuous source of material at a lesser cost than conventional plants.

The idea is to create a way to make foam from paper mill waste, simultaneously reducing waste and creating a useful product. Some of the finer waste fibers from paper making are excellent feed-stock for nano-crystalline cellulose (NCC). Why not develop a method of processing the NCC into composite foams by adding a furan resin to the unprocessed foam. Paper mills create millions of tons of waste product annually, much of which could be re-used in this new method of foam...

The idea is to create a new body fluid testing device, made of paper and designed with the medical needs of developing nations in mind. The paper will be based around the idea of using origami properties to create a three-dimensional microfluidic biosensor that can be shipped flat and easily put together. A printer will be used to deposit a hydrophobic material into tiny canyons on the paper, which will guide the fluid samples to reagents. The reagents will then react by changing...

The new bottle is supposed to encourage environmental awareness by allowing the user to keep track of how many plastic bottles they have saved from the landfill. The bottle features a stainless steel canister with an integrated, rubberized dial that lets the user mark off each plastic bottle saved at each refill. It also includes an iPhone app that can translate the saved plastic bottles into oil savings or allow the user to track progress collectively with friends.

A new method of manufacturing blue jeans is making them greener while saving energy and materials. The advanced denim process will reduce the amount of water necessary to make a pair of jeans by up to 92 percent while also generating 87 percent less cotton waste, and producing less greenhouse gasses and waste-water. The process will use a single dyeing vat and replace conventional indigo dyes with eco-advanced liquid sulfur dyes that will require only one sugar-based reducing...
