I'm working on a black hole battery in my garage.
The only problem is that I can't seem to make it stop sucking. I guess it will end up being a battery for vacuum cleaners only.
Amateurs... You did it too big!!!!
As every kid in 5º year knows, black holes evaporate at a speed inversely proportional to their mass, so a smaller black hole should work for a decent vacuum cleaner. Watch out Hawking radiation, though.
In a (somewhat) more serious note, I find it hard to imagine that someone would create antimatter batteries. Sounds cool and all, and very mass-efficient (E=mc² after all), but it doesn't seem productive to me. I mean, you need such a huge amount of energy to create antimatter today. But for the brighter minds, please, go ahead!
I am not amazed by F1 cars in Monaco. I want to see them driving in the A8 highway: Variable radius corners, negative banking, and extreme narrowings that Tilke has never dreamed off. Oh, yes, and "beautiful" weather tops it all.
