This is an amazing concept and while the Dastardly & Custard lemon-powered torch is only an idea, the Japanese have invented a water-powered torch. It is called “The NoPoPo Mini Lantern” and is only $38. I won’t blind you with science (you can blind yourself with the ‘read more’ link), but the fact it will run for up to ten years is awesome. Particularly handy in the UK with all the rain! References: currentFiled In: |
