The idea is to create a device to project a laser image onto the road in order to make drivers more aware of bicyclists. The device is meant to be mounted on the handlebars of a bike, where it will project a bright green bicycle symbol on the road in front of the cyclist. The symbol will be visible by day or night, and will shine steadily as well as flashing off and on.

Why not create multi-account credit cards? This will eliminate the need to carry a separate card for each account. Such a card will allow a user to select the account to draw from (an active account will be indicated with a small blinking light on the credit card); it will be possible to swipe it just like a regular credit card. The card will also have the built-in battery which is good for 4 years of normal use.

My idea is to create a mobile device which can be used by deaf and hearing-impaired people. I suggest creating a tool which would be integrated to any high-end mobile phone with a video camera. The tool would be based on motion detection technology, i.e. it would be possible to identify American Sign Language (ASL) and transmit video images over cell networks in the US.

An entrepreneur from Arizona decided to use polymers to create a product that literally saves human health, thanks to its cooling properties. He suggested sewing polymers inside the material and creating stylish scarves, which can cool in the hot weather. The principle of the cooling scarf is the following: when it becomes wet, polymers absorb moisture and through the natural process of evaporation create a cooling effect in the area of the carotid arteries, vessels of back and...

Do you still use rake to pick up leaves in your yard? I suggest a new idea how to make your yard clean easily. What about a vacuum with a bag attached which you can place on your back? It could look like an industrial blower but it would pick the leaves up instead of blow them away. It could have either electrical or gas engine. Such a vacuum will definitely save time and make the yard work a little easier.

I often can't remember where I have left the TV remote control and look for it all over the room. So I suggest creating some device which is placed on the TV and makes the remote control beep when I need to find it. The functionality seems to be similar to the one which wireless phones have.

The idea is to develop a new ECG detecting steering wheel. The steering wheel's sensors will detect abnormalities in the driver's heart rhythm, alerting the driver through a display monitor. The system will include a monitor on the in-car navigation system that will display a chart of the driver's heartbeat and electrocardiogram, allowing the driver to keep constant tabs on their heart rhythm.

The idea is to create a backpack mounted rainwater catchment systems that will be portable enough to harvest and clean rainwater, as the weather permits. The rainwater catchment and filtration system will be built using off the shelf components from a standard store. An expandable bag will collect and hold the water, while the built in filtration layers will render it clean enough to drink. It will be worn on the back or stand alone, and will also be used in conjunction with...

The turbine will be easily assembled and pack flat for transport. It will be retrofitted on a roof without the need for a supporting unit, and will be a self-starting turbine, able to cope with variable wind speeds. The turbine design will be adapter to sizes from 1 to 24kW, and its minimal noise will make it both wildlife and neighbor friendly.

I wish I had some kind of an insulin doser inserted in my leg. The doser would check constantly my blood and deliver the right amount of insulin when needed. I would be able to recharge the doser with an injection to it. Such a device can definitely be used for almost any medicament.
