When will someone design a homebrew widget.
Think of it. A small aluminum tablet that contains beer gas with 2 membranes. One designed to disolve upon contact with liquid and carbonate the beer. The other designed to burst during the sudden drop in pressure when opening the bottle releasing a "Big" stream (cause everybody knows hombrewers spray big streams

) of beer gas creating that creamy head.
Oh yea and make it affordable too.
When we get this done then maybe we can move on to cold fusion or something.
