Building of the week – the passive solar greenhouse

Generally speaking, eating local food is going to be better for the environment, as it won’t have been transported long distance. There are exceptions though, and among them are out of season salads and Mediterranean vegetables. British growers can now produce crops such as tomatoes all year round, but in winter that relies on extensive […]

Digital currency goes mainstream

Bitcoin is the best known of them today, but the internet has spawned a whole range of digital currencies. Up to now they have been the province of enthusiasts, but central banks are beginning to debate the merits of issuing their own digital money. China have been studying the online currencies and recently announced that […]

A global alliance to fight inequality

I know I keep mentioning things related to the World Economic Forum, but it does seem to kick off the year with a blaze of reports and new ideas – and I haven’t even mentioned the official topic yet, the ‘4th industrial revolution‘.

Making plastic out of greenhouse gases

Greenhouse gases, as we all know, cause climate change. We create CO2, methane, nitrous oxide and so on as we burn fuels in our cars, heat our homes, and generally go about our business – it’s a waste product of modern civilization.

The Solar Revolution, by Steve McKevitt and Tony Ryan

This is a slightly odd book. On the back it says: “The Solar Revolution tells the story of how scientists are working to reconnect us to the ‘solar economy’, harnessing the power of the sun to provide food and energy for a population of 10 billion.” I bought the book on the basis of that […]

More plastic in the sea than fish by 2050

There’s an extraordinary report out from the Ellen MacArthur Foundation this week, part of the flurry of ideas that always accompanies the World Economic Forum.

Did Ikea just admit to peak stuff?

Five years ago Chris Goodall observed that Britain’s materials use was falling. Had we reached ‘peak stuff’, he wondered. As economies develop they reach a saturation point. We need vast quantities of steel and concrete as infrastructure is built, but then demand tails off – possibly. The downward dip in Britain’s consumption of materials was […]
