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.
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(Link)
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.

"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.

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.

Under the sign of his "eco-gym," Gimnasio Ecológico Lumen, Manuel de
Arriba Ares has turned the demon of entropy on its head. Making use of
the very waste and byproducts of the modern entropic economy, Arriba has
created a truly practical monument in the form of a supremely low-tech
gymnasium. Its fitness machines, created with a good deal of physical
effort over three years from raw and junked materials such as wood,
rope, and rubber, directly mirror both the design and functionality of
those found within its wasteful counterpart.
Located in the small town of Valdespino de Somoza in the north of Spain, Arriba offers free access for all to this functional work of Art Brut, a wonderful Heath Robinsonesque assemblage constructed from remnants of strollers, boats, bicycles, and automobiles salvaged from neighboring dumps. Helpful signs, painted on the tarnished white remnants of refrigerators, instruct the would-be eco-gymnast on exercises and operation of the intricate machinery, reflecting Arriba's knowledge and experience over many years as a physical education teacher.(Link)
We take running water for granted, but millions of people in the
developing world are forced to carry buckets of water home (sometimes
from miles away). Innovation like this Q Drum rolling container makes
their lives a little easier.

Low-tech scuba dive system
Using a pipe connected to a rudimentary oxygen compressor, divers from
Bangladesh can go as low as 200ft in some of the world's most
fast-flowing rivers.
It's a kind of low-tech scuba diving: the divers use a pipe connected to a compressor which is normally used for blowing up tyres. They go out into the middle of the river on a boat, tie themselves to a rope and dive in. The idea is that if they get into any kind of trouble, they pull on the rope to indicate that there is an emergency.

Batphones (hear amplifier)
The name alone makes these worth writing about: Batphones. The low-tech
hearing aid is an update to simply cupping your hand to your ear. The
side “scoops” channel sound from in front directly into the ear, much as
a satellite dish focusses the signal into the antenna. Matthias Ries'
concept isn't meant to be a replacement for regular hearing aids, but
more as an enhancement for people talking in loud places, or those with a
small amount of hearing loss.

Japanese Hot Tub
No bubbles, no jets, no electricity, nothing to break, just deep hot
water up to your neck. Asians have known for thousands of years the
benefits of sitting alone immersed in hot water. Basically, it is just a
plywood box with a cool Oriental name (Furo). At first glance it seems
like you may have your knees in your mouth, but this is not the case,
due to your natural buoyancy—you feel so good you just don't care. You
get the same benefits of a hot tub, but none of the contamination
consequences, plus you get to be alone and not feel completely
antisocial.
