How tech can help build communities
Connecting remote places to the world
Almost half the world's population is still without internet access. People in poorer, remote regions lose out – because the repercussions are far greater than not being able to send a few messages. They miss out on opportunities for education, business and development, such as in remote villages in Nepal's Himalaya mountains.

3D-printing houses in eight hours?!
Imagine this: People need shelter and within eight hours, you've 3D-printed a house for them. That's what a professor at the University of Johannesburg is envisioning with his students. That could help solve South Africa's housing crisis, because these 3D printed houses are supposed to be quicker to build and even cheaper than regular brick and mortar homes.
