Recently, watching a bank robbery movie I got an idea that I'm sure will be useful for improvement of all kind of safes either huge walk in banking safes or small personal safes. I would set the safe to open with two or more secret combinations where only one is the real combination which just opens the safe. Other combinations would open the safe too but along with that they would automatically trigger the alarm system. For small models we can integrate a simple wireless card which in...

My idea is to create sportswear with built in flexible electronics to monitor an athlete's biological indicators, like pH levels in sweat, heart rate, or blood pressure, generating data on metabolism or other factors and beaming it wirelessly to a trainer's laptop. The electronics could also simply count the steps to measure the distance traveled or the number of reps completed. Having such a sportswear will remove the need for some clunky external device to record or transmit...

Isn't it great to have a temporary refuge that allows visitors to enjoy the wilderness while preserving the pristine environment? The self-supporting solar powered cabin will designed to be transported by helicopter to the desired area and set up on pipe piers, with minimal impact to the site. The water will be delivered by snow melted by the solar system; appliances will be powered by the solar electric system. There will be a supply of bioethanol available for emergency needs,...

Torque vectoring gears for wind turbines eliminate the need for the twofold conversion process required before the current is fed into the grid. The process of converting the current produced by the turbines into an alternating current of the right frequency results in a loss of almost five percent. To prevent this loss, I suggest developing an active torque-vectoring gear that can operate at exactly 1500 revolutions per minute regardless of the rotational speed of the motor. This...

My idea is to provide fire trucks with a system which is a combination of a conveyor belt and a ladder. It could help firemen move people more quickly from burning buildings. The system will contain rungs on rollers that will slide on tracks. Such a ladder will be able to lower four people to the ground in 4 minutes while the standard time for rescue, using traditional methods, is about 15 minutes.

I suggest using a new method of steel processing which results in an end product that is lighter, stronger, and more environmentally friendly than traditional methods. The process takes only ten seconds, rather than the hours or days of heating in conventional steel plants. The metal is flash heated and then quickly cooled, which alters the microstructure of the steel and results in a product that is 7% stronger and 30% more flexible than traditional steel. And since the...

The idea with that artificial rainbow is fantastic. A rainbow machine has been already created. It uses reclaimed rainwater and sunlight to create rainbow effect. The machine applies jet pumps and custom fountain nozzles to spray water in the air, and then the sunlight shines through to create the rainbow effect.

Why not create piezoelectric artificial trees able to collect rainwater and generate electricity? The tree will be able to use water from rainfall as well as the natural water table as irrigation; wind energy will provide power for the LED lights.

The composition consists of suspension polyvinylchloride, stabilizer and filler. The new idea is to use chemically precipitated chalk as the filler. The composition includes components in the following mass parts: 1. Suspension polyvinylchloride - 100 2. Dioctyl phthalate - 60-120 3. Epoxidized vegetable oil - 10-20 4. Chemically precipitated chalk - 100-200 5. Barium stearate - 0.25-0.5 6. Cadmium stearate - 0.25-0.5 Suggested...

A new alloy is able to convert heat directly into electricity. The alloy, a multiferroic composite of nickel, cobalt, manganese and tin, can quickly and dramatically change from non-magnetic to extremely magnetic when heated only a small amount. When the alloy is located near a rare- earth magnet, a current is produced in a surrounding coil. The new allow could have applications in harvesting waste heat from car exhausts, particularly since many hybrid batteries already have...
