This month Horizon looks at the latest technology to turn on power in places which are off the grid. We learn about solar power tech that's being used to clean water, bring internet to mobile phones and even sustain temporary housing pods after a disaster. We also hear from Michael Gera, who’s investing in off-grid energy companies in Africa, so that businesses can stay open and children can study after the sun goes down.
A new breed of emergency shelter with built-in solar power, a backpack that gives access to mobile charging and a bag that converts manure into cooking gas are among the new generation of emergency response kits that could help people survive in the wake of a disaster that knocks out their energy supply.
Mini-grids, mobile payments and smart meters are all helping to create an off-grid model of electricity provision in Africa, helped by bottom-up funding and low-cost solar power, according to Michael Gera, managing partner and co-founder of specialist venture capitalist firm Energy Access Ventures (EAV).
It's been 15 years since the euro came into circulation and to mark the occasion Horizon is looking at what the future could have in store for finance. We talk to one economist who says the way to avoid another crisis is to keep banks small and boring, and we explore the effect of alternative local currencies on supporting small businesses. We also delve into some of the technology that could enable us to move to a cashless society, and we look at the growth of the so-called sharing economy, in which people share access to resources.
This December marks one year on from the Paris agreement, where world governments agreed to keep global warming to within 2 degrees Celsius of the average pre-industrial temperature. To mark the occasion, Horizon takes stock of the situation and examines the challenges ahead. We speak to scientists who are mapping a pathway for governments to cut back on emissions, we host a debate on steel - one of Europe’s most polluting industries, and we look the progress of carbon capture and storage. We also interview Professor Hans Joachim Schellnhuber, founder of the Potsdam Institute in Germany, who was the first to propose that 2 degrees should be set as a limit for global warming.
In the province of Limburg, in northeastern Belgium, residents earn points by helping out in the community which they can spend on cinema tickets or trips to the local swimming pool.
The increase is partly driven by climate challenges.
Neuroimaging techniques are helping us read the pictures in our heads.
There is unlimited kinetic energy all around us and harnessing it could change the way we interact with the world, says Dr Gonzalo Murillo.
