Thanks for sharing, that was an interesting read.. I wonder if endurance is an issue since each cell is so much smaller? Failing that, it may be price-fixing between competitors (which is illegal but sometimes happens).. It is surprising that nobody has brought this to market yet (that I am aware of) which makes me think its either leaving out critical issues/problems (e.g. endurance) or it is a conspiracy by market leaders to keep the pricing at current high-margin levels.
Sooner or later, if the technology actually delivers on its promises, someone will get greedy and undercut everyone else and flood the market with these.
