I liked chemistry at school because it's just like cooking. You put in the right ingredients and you know exactly what you'll get out.
Scientists are looking for simple chemical reactions that could reduce carbon emissions from power stations. One idea uses a mesh of sodium carbonate microcapsules - the mesh reacts with carbon dioxide and water in the air to make baking powder (sodium bicarbonate). It's 40% cheaper than current carbon capturing methods - plus baking power is non-toxic.
It may take a while to make enough of the mesh to be useful, but going back to basics could make a real difference.
