1) Students can keep fit and make a few bob delivering fastfood meals via Deliveroo or Uber Bites. Apparently most of their customers are other students. Deliver two meals and have one delivered to you as payment. Eat after a quick shower. Eat for free- no washing up. Would this be a solution to world hunger? The answer is no- because the maths do not add up. If one food delivery equaled one meal, it might work- but it does not. At least two people provide me with £14, which might be the cost of my meal. But of every one meal I get, two people must pay. This is a mirco picture of why 1/3 of the world is rich, and 2/3s poor.
2) Construct a bridge to encircle the whole world. It would be a complete ring. Then remove all the supports. The bridge would hover in the sky, equally pulled to earth by gravity, but also equally held up by the internal forces in the structure. It would create minimal environmental damage and join the world together as one. (Free too- as it remains in my imagination.)
3) Plant a tree on every grave. This is starting to happen- It's what you opt for at a natural burial site. Young trees need tending, and graveyards often have water points. (Churchyards would be exempted, especially if they already have Yew Trees.)
4) Free Uber. Sign up to a car sharing website that requires everyone to contribute equally. I want to travel to London tomorrow at a particular time. All the people making the same journey can advertise the number of spaces in their car. If they give someone a lift they accrue the equivalent of airmiles. These can be cashed in either with free rides, or other privileges. People who do not have a car pay a low rate. Each driver and passenger get uber-style ratings as a safety check.
