What would you like to see invented then?
1. Food replicators like on Star Trek - end to world hunger there.
2. Cars that run on cow poo.
3. Football shorts with self-activating springs that throw you back upright if you drop to the floor too dramatically.
4. Seriously - a cure for Alpha-1 would be nice so my friend's son could have a normal childhood. It's a genetic condition affecting the liver and later on the lungs.
