"Market collapse". If only.

Full tank of what? A car? Truck? Semi? A generator? A Jerry can? Obviously petrol is better. You can always charge your phone in a vehicle or generator. If it's a generator, you could also power a home. You could also sell the gas for much cheaper by constantly siphoning it.
Anyone picking a charged phone is a fool I tell you, a fool! I'd be rich with my unlimited petrol.
Well, it's sort of possible to compress large things into small sizes. But I don't think it would work for this situation.
There are things called ".zip bombs". Where an otherwise small file, when unpacked, can take up a large amount of space.
A famous example of a zip bomb is titled 42.zip, which is a zip file of unknown authorship consisting of 42 kilobytes of compressed data, containing five layers of nested zip files in sets of 16, each bottom-layer archive containing a 4.3-gigabyte file for a total of 4.5 petabytes of uncompressed data.
Nothing. Anyone who uses the Death note cannot go to heaven or hell. That would basically confirm the existence of heaven and hell. My understanding is that heaven is infinite. Nothing in this finite world would be worth risking infinity in paradise. I would take it, chat with a god of death, ask many questions, and then decline.
FYI, this is the Beaverton y'all. It's satire.
