Answer to "What future teardowns should we do?"Keurig drinkworks machine. Unlike the sodastream, this unit still has to be retro fitted for a large CO2 tank. 74g cartridges from Keurig are 7.50 each and make only a handful of drinks. Would love to see a complete teardown with detailed pictures of how the CO2 apparatus is engineered. Nothing to this date exists and a solution needs to be figured out. For anyone that doesn’t know, drinkworks makes alcoholic cocktails just like the coffee versions but for “adult" drinks. Mai Tai, rum punch, mojitos etc. Carbonation capabilities included if the drink requires it. Help up vote this!!!!
