09:05 Warnings that big uptake of solar panels will increase cost of power for those who don't have them

09:30 You've heard of 3D printers ..now comes 3D bar-codes!

The global market in counterfeit goods, is estimated to be worth  $2.6 billion every year and over half of pharmaceuticals sold online are thought to be counterfeit. Engineering company Sofmat, is developing 3D bar-codes, invisible to the naked eye, to help stop this lucrative global market.

The codes consist of a series of small indentations with precise, slightly different depths, allowing for billions of different combinations. With four pins making holes at 36 possible heights, the team can produce 1.7 million codes. Next they want to step up to a six-pin system, with more height variation, which will allow 14 billion variations. The Sofmat team hope to launch their barcodes in November 2016. Phillip Harrison is Sofmat's managing director
