5. Adjustable Glasses
British inventor Josh Silver began working on eyeglasses that can be tuned by the wearer in 1985. His goal is to bring better vision to a billion people worldwide who cannot afford, or don’t have access to, an optometrist. He has devised a pair of glasses which rely on the principle that the fatter a lens the more powerful it becomes. Inside the device’s tough plastic lenses are two clear circular sacs filled with fluid, each of which is connected to a small syringe attached to either arm of the spectacles.
The wearer adjusts a dial on the syringe to add or reduce amount of fluid in the membrane, thus changing the power of the lens. When the wearer is happy with the strength of each lens the membrane is sealed by twisting a small screw, and the syringes removed. The principle is so simple, the team has discovered that with very little guidance people are perfectly capable of creating glasses to their own prescription.
Silver’s goal is to distribute a billion pairs of his adaptive glasses to poor people by 2020 .
Already, 30,000 pairs have been given out in 15 countries. Her hope is to get the cost of manufacturing each pair down to a dollar each.
4. Non-electrical Refrigerator
Mohammed Bah Abba made a really cool invention, which won a Rolex Award of $100,000 –a refrigerator than runs without electricity. Here’s how it works. You take a smaller pot and put it inside a larger pot. Fill the space in between them with wet sand, and cover the top with a wet cloth. When the water evaporates, it pulls the heat out with it, making the inside cold. It’s a natural, cheap, easy-to-make refrigerator.
Evaporative fridges are a relatively well-tested, proven, low-tech approach to cooling. They can cool products, food and beverages at about 15-20 C below ambient temperatures. They are most appropriate in hot, dry (not humid) climates.
3. Amphibious Bike
Li Weiguo is the man who designed and built this floating bicycle, and the girl riding it is his daughter Li Jin. His amphibious bicycle has eight water buckets that act as pontoons and adjustable vane wheels that provide the driving power. It might not look as good as other custom made bikes, but at least you can ride it on water and land alike, and that’s the whole point. The amphibious bike was presented on May 30 2009, in Wuhan, Hubei Province, China.
2. Eye-contact mirror for web cam
“Here is looking at you, Kid” by Berlin-based artist Aram Bartholl, is a low-tech way of fixing the annoying aspect of video conferencing where participants are not making “eye-contact” through their web cameras. Rather than looking at the camera, the typical person stares at their screen, thus not making eye contact with the person they are chatting with. The device is made of a mirror, some glass with mirror foil, and a piece of cardboard, in order to mimic what a teleprompter does to text for a TV news anchor. The result allows the viewer’s eye contact to connect with the person and a final manufacturer fix might be to integrate the camera behind the LCD screen so that you can actually look directly at the other person.
1. Moped Cone
This invention, despite of its simple brilliance and usability (the Swedish Army had tons of these for their motorcycle messengers in the day), was overrun by newer technology – like the motorcycle helmet with covering visor. The moped cone over time infiltrated into civilian life, and although it was mocked and ridiculed it was pretty smart in its simplicity. When riding a moped or motorcycle in the winter, and as long as you kept a reasonable speed, the cone helped form a cushion of warm air in front of your face, preventing the cold winter air from entering and deep-freezing your face. This surely saved a lot of noses from frostbite. In the summer the cone would prevent raindrops or insects from hitting your face, but as far as we can remember they were mostly used in the winter.
