It would be great if someone invented a holographic TV. There everything you see would be projected creating a feeling as if it was actually there.

In an effort to slow coastal erosion, why not develop concrete cylinders that can cancel out up to 90% of a wave's intensity? The cylinders will be hollow with narrow slits in the sides and will cancel out the wave's energy. The cylinders should even be able to handle tsunami waves, and it will be possible that current wave power generation systems could be adapted to the coastal protector technology.

Fingerprints are unique to every human being. I suggest using fingerprints in ATMs. Banks could register a fingerprint in a bank system when opening an account. The whole procedure would be easy and secure if a person went to an ATM, placed his/her thumb on the reader, entered the security code and did his transaction.

I'm sick and tired of the fact that I spend so much time looking for a parking place. My idea is to create a system that will help people to find places for their cars to park. The system will consist of wireless detecting devices placed on the territory of a car park that will check parking places availability and send the information to a single control centre. Then this information will be displayed on information panels or sent to some kind of navigation gadget (similar to a...

The idea is to develop an invisibility cloak that will trap sound waves, preventing the sound from leaving the material. The proof of concept 'cloak' will be a small, thin plate made up of rings of micro-structured polymer material that will resonate at different frequencies. Sound wave vibrations will follow a circular path around the plate, unable to leave the material. The cloak will differ from conventional noise protection devices in that the sound waves will be neither...

Let your friends and family experience life through your eyes with the camera glasses. The glasses will feature a tiny camera in the center able to record audio and 720p video, which will be saved to an SD card. The captured video will then be posted on the video sharing site, which will connect with a number of social media platforms. The glasses will also function as electronically powered sunglasses, with the lens tint able to shift from lighter to darker with the press of a...

This idea can help blind people to gain partial eyesight. There will be a microchip to be implanted onto a patient's eyeball. The patient will wear special glasses with a camera that transmits images to the microchip and fires an electrode under the retina, stimulating the optic nerve.

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.

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...

It seems to be a great idea to create a harness which will allow dogs to be guided remotely and controlled while out of sight. The harness will come with GPS, sensors, and wireless modem allowing handlers to keep track of the dog while issuing commands from a distance. The system will relay the commands to the dog in the form of vibrations or tones that the dog has been trained to recognize.
