The glass table surface contains a special solar cell which creates an electrical current.

It means that the cell doesn't need direct sunlight to work, and can rely on diffused light instead.

Project Daniel is the world's first 3D-printing prosthetic lab.

The founder, Mick Ebeling, tracked down Sudanese teenager - Daniel Omar - who lost both his arms when a bomb went off while he was tending cattle.

Two 3D printers have since been left in the local hospital so more people can receive artificial limbs - for a cost price of about $100.

This billboard in Peru below might look ordinary - but it is actually hard at work attracting and filtering pollution from the sky.

It then returns purified air to the local atmosphere at a rate of 100,000 cubic metres per day.

It would take 1,200 mature trees to do the same.

This building looks like it has been there for generations - but it is the new Sancaklar Mosque in Istanbul.

The designers Emre Arolat Architects were inspired by the fact that a mosque does not have a predefined form, and that anywhere clean may be a prayer room.

Seeming, in part, to defy gravity - the towers of the One Central Park project have transformed Sydney's skyline.

This photo was taken at the Waterbank Campus at Endana Secondary School in Laikipia, Kenya. Each building at the school harvests rainwater.

The football stadium seating - with the rear of the structure shown here - is no exception.

The Ocean Cleanup is inspired by Dutch environmentalist Boyan Slat - who, at the age of 16, encountered more plastic bags than fish in the waters off Greece.

It's a proposal for a network of floating barriers which cause natural currents to push plastics towards a central platform - to then be removed from the water.

These lampshades have been "grown".

Created by Ecovative, they are made out of high-performing biocomposite material - which uses fungal mycelium, the root-like structure of a mushroom.

It means that agricultural waste products can be glued together into products - which can then be returned to the soil as a nutrient at the end of their useful lives.

"Grow it yourself" lampshades - Ecovative, finalist in Designs of the Year 2015

As in previous years, the nominees in the transport section are focused mainly on eco-production and efficiency.
