The scale of need and human suffering around the world, quite often overwhelms us. In reality, it's the simplest of ideas and thoughts which can make a quantum difference in their every day lives.

Sharing a few examples, which are both inspiring and humbling in their simplicity and impact.

1. The Berkeley Darfur Stove

As women trekked for miles, into remote war torn areas from their camps, the simple task of collecting firewood often meant loss of life! The Berkeley Darfur stove is an ingenious mechanism, reducing by half the amount of wood required and the emissions from the burning. 

2. Adlens Adjustable Eyeglasses

Adlens manufactures eyeglasses which can be instantly adjusted to suit the user. They are intended for use where prescription eyeglass fitting is not available and emergency situations where replacement eyeglasses are needed immediately. The polycarbonate lenses are hollow and filled with fluid. Removable adjustment knobs on each lens add or remove fluid to adjust the magnification!

3. Bamboo Bicycles

The goal of the Bamboo Bike Project is to test the feasibility of implementing bamboo bikes as a new form of transportation in Africa.

There are several advantages to making bicycles out of bamboo. Since bamboo is grown locally in Africa, and the manufacturing of bamboo bicycle frames does not require extensive infrastructure (or even electricity), bamboo bicycles have the potential to be a sustainable business that provides local employment even in areas disconnected from power and other facilities. 

However the use of bamboo at a much wider scale even for more developed markets is worth considering, with it's huge environmental benefits, lower cost and larger sustainability impact for the planet!

4. The Hippo Roller

The Hippo Roller makes it extremely easy to collect water in tough rural conditions - up to 5x more water than a single bucket, by simply rolling it along the ground.The Hippo Roller is very user friendly for women, children and physically weak as it makes the transportation of water much less strenuous than traditional methods

5. Disaster communications system

Cell phones are common even in poor countries, but when a natural disaster strikes, the communications networks, these devices rely upon, can fail. Developed in Chile, SiE is a system that encodes text into high-frequency audio tones that can be distributed over broadcast radio waves and received on any smartphone without requiring any internet infrastructure. An app on the phone listens for these tones and transforms them into a text message.

The applications of this technology are enormous in disaster zones across the world!
