A greener cup of tea

We’re always being told not to waste fuel, so here’s a way that saving a gram or two can make a real difference – to us if not to the planet. Exchanging gas bottles can be a hassle, so try counting how many strokes on the hand or foot pump it takes to fill a mug, then use exactly the right amount in the kettle. Overfilling wastes a surprising amount over the weeks. If you’re unlucky enough not to have a manual pump in the galley, count how many seconds the job takes on the electric one instead. The secret benefit of the manual pump is that you can give it a simple in-line filter and know your tea will taste great every time. It’ll last for ages if you keep it for drinking and use the power pump for washing up.
