The idea is to create a flashlight that can use any number of almost any type of battery, ensuring you're never left in the dark. The flashlight will accommodate AAA, AA, C or D batteries. The batteries will be loaded into a container that can be rotated to select the battery or turn the flashlight off and on. The more batteries loaded into the device the longer it will operate, with the maximum run-time estimated at 86 hours.

A new range of Wi-Fi SD memory cards adds wireless capability to any compatible digital camera, letting photographers review and share images instantly on smartphones or tablets. The Wi-Fi SD cards feature a SDHC class 10 speed rating and are available in either 16 or 32 GB capacities, which is a larger capacity than any other currently available model. The cards include Direct Share Mode, in which the card's own wireless signal communicates with a mobile device, and Internet Mode,...

The skies will get a bit safer for birds with the wind turbine, which will use no blades at all. The turbine will capture up to 80 percent of the wind's kinetic energy (current turbines only capture about 30 percent). Instead of spinning blades, the wind will be harnessed by a sail that will move in a non-rotational back and forth motion. The motion will then be converted to a hydraulic pressure that can either be stored or instantly converted to electricity via a hydraulic motor...

In an effort to re-use the million of tons of building rubble produced each year, a way to recycle concrete with lightning was found. The lightning bolts of a short duration are more likely to pass through a solid. The idea is to produce lightning bolts and direct them to the concrete. As the lightning follows the path of least resistance, it separates the material into its fundamental components. A concrete recycling plant using the lightning method could be a reality in as...

Replacing lithium with sugar could create stronger, long-lasting batteries with more energy storage capabilities. The idea is to heat sucrose to as high as 2,700 °F in an oxygen-free atmosphere. This process, called pyrolysis, results in a hard carbon powder that can be embedded in a sodium-ion battery to create a storage capacity 20 percent greater than conventional hard carbon.

The door-free refrigerator concept will save energy by not refrigerating empty areas. The refrigerator concept will replace the door with a honeycomb wall of hexagonal chambers. Each chamber will be covered by a plate that will move aside when an item is inserted, exposing the item to the system of refrigerated pins. Since only areas with objects in them will be refrigerated, this refrigerator will use less energy than conventional ones. And since the items stay in sight, there...

The new device makes cycling safer, and perhaps more stylish, by putting the rearview mirror on the rider's wrist. The device features a small convex mirror attached to a small, metal, snap bracelet. To use, the cyclist simply lifts their wrist to check the street behind. The wrist mirror is safer to use because it eliminates the impulse to turn the wheel to check behind while also providing a wider field of view.

The counter will attach to IV bags to instantly measure the amount of liquid being dispensed per hour, replacing the more expensive fluid dosing pumps that some remote hospitals are unable to obtain. In poor areas and disaster locations, medical personnel must often count each IV drop manually in order to estimate the dosage being delivered. To reduce this demand on staff, the device will clip easily to the IV tube and count the drops by measuring the changes in light between a LED...

A tiny blood sugar sensor able to continuously monitor the glucose level of sweat or tears could mean the end of daily finger pricking for diabetes management. The new sensor will measure only 0.5 x 2.0 millimeters and can be worn on the patient's body, where it will take glucose samples from sweat or tears. Because it will require only 100 micro amperes to operate, it can be used continuously for months at a time. The device will also feature a wireless system able to...

The Life Light lifesaver ring can be seen even at night, making it easier for both rescuers and victims to find. A combination marker buoy and lifesaver ring, the Life Light concept was designed to be more environmentally friendly while also remaining practical. The ring's stand is easy to install but difficult to remove, with a flared tip that opens when pulled upward from the sand, and the integrated LED lights ensure the ring is easy to find at night.
