It seems a reasonable question and of course the answer is yes, there is a chance we could do something about this. The same technology that helps power Philae is readily available here on earth. Nearly every time I go into B&Q or my local garden centre there is a stack of solar powered lights in the discount section being offered at knock down prices, you can't give them away. The issue is not can we do something about the problem but will we do something about it? Are we prepared to invest the same commitment and resources that delivered Philae to 67P to addressing some of the basic needs in our world? Needs like clean water, basic sanitation, health care and renewable energy. Let's face it, it's not rocket science (or rocket surgery as one of the muppets on The Apprentice last night blurted out).
