Giant fans are sucking in fresh air from the Swiss Alps and Iceland's frozen interior, capturing the carbon dioxide and turning it into fizzy drinks or burying it deep underground. Tom Heap gets up close to the extraordinary Climeworks device at the Science Museum in London and talks to the team that's developed it to ask if they've designed the solution to climate change or created a potent symbol of our failure to cut carbon emissions? Dr Tamsin Edwards of King's College London joins Tom to crunch the numbers.

Why use gas or electricity to heat your water when the power of the sun will do it for free? Faisal Ghani, a young Bangladeshi-Australian engineer, has invented a deceptively simple glass pyramid that takes cold water in at the bottom and supplies hot water from the top. He believes it can bring cheap, hot water to every home around the Equator. In the first of a new series packed with carbon-busting ideas Tom Heap visits Faisal at his Dundee production line to hear about his plans to bring hot showers to the world. Climate scientist, Dr Tamsin Edwards of King's College, London, helps Tom calculate just how much carbon hot water from the sun can save.
