Just a decade ago most of us wouldn’t have dreamed we’d live to see driverless cars whisking people around, but things are changing fast and analysts now think they will be common by 2020 and account for the majority of cars on the road by 2040.

Solar roadways used to be just a concept, but Scott and Julie Brusaw have built them to withstand the weight and wear of trucks and heavy traffic, while producing electricity. Now the question is whether they can raise enough money to set up mass production…
With electronic equipment and gadgets the fastest growing waste stream in many countries, how to deal with so-called “e-waste” may in fact be one of the most pressing environmental problems of the 21st century.
