There will be an opportunity to find diet food, different national dishes, etc. The prices will be specified by sellers but they will always be able to feed other people even for free. Buyers will use...

Why not throw out your wires and charging mats and charge your phone wirelessly, just by setting it near the laptop? The laptop will charge the user's mobile device through a pair of transmitters, one each built into the laptop and phone.

The fish finder sonar orb will pair with a smart phone to scan beneath the water, letting you know the best place to sink a hook. The fish finder will be able to withstand depths up to 120 feet and have a Bluetooth range of 150 feet. Once tied to a line and submerged, the waterproof orb will use sonar waves to gather information about temperature, depth, and the locations of the fish. The information will then be sent to the phone in the form of a depth chart image, with...

Most people who are color blind do see some color but are unable to differentiate between red and green, which is the most common form of color blindness. New sunglasses feature a proprietary coating that compensates for red-green CVD by reducing the transmission of certain wavelengths of light, which allows the red and green wavelengths to stand out. The sunglasses will not work for people who can see no...

Why not combine photovoltaic panels with OLED's to create panels that can be adjusted to face the sun as well as create designs or messages on the sides of buildings? The panels will be made of aluminum and stainless steel. During the day, the panels will be adjusted to maximize solar energy absorption while at night they will be flipped to allow the OLED screens to provide light for interior rooms or media playback.

Why not develop a robotic golf caddy that will happily carry the user's clubs and never expect a tip? The robot will be programmed to follow an individual, moving at walking speed and automatically stopping when the user stops, or it will be driven by remote control. Lightweight and foldable, it will be able to travel inclines as much as 30 degrees and carry up to 45 pounds.
