Shining the light on a more sustainable globe

Artificial lighting methods have changed with the invention of new lighting technologies designed to be more energy efficient and to reduce the use of resources. Since electricity has been used as an energy source, incandescent and fluorescent globes and, more recently, light emitting diodes (LEDs) have been used in our ...

It's not a square house

In this interview people talk about how they worked together as part of a community to build their unconventional houses. They describe the influence of Buckminster Fuller, and how they shared ideas and experimented with local building materials. See how they achieved their aim to be self-sufficient and sustainable.

Getting satellite design right

Is it a good idea to build a complex and expensive machine without carefully checking the design first? This animated clip describes some of the steps NASA took during the design review process for the development of a new satellite. Can you think of any other steps in design reviews?

Learning from design 'mistakes'

Finding the solution to a design problem involves generating creative ways to address a need or difficulty. Design is the key and it often involves an engineer. In this clip, explore what an engineer is and what they do, and see an example of how NASA engineers might plan, create and test an idea to fix a space station.
