This sounded real familiar, so I went and dug up the last one of these I heard of.
The ZPM Nocturn was supposed to be a $400 espresso machine that used a fancy thermoblock instead of a boiler to save costs (cheap espresso machines use thermoblocks, but the kickstarter claimed that their design was better enough to compete with a boiler).
This is straight from their kickstarter page: [1]
> There are basically two kinds of home espresso machines on the market today. The affordable models have no good mechanism of temperature or pressure control. These machines can’t pull consistent shots. So if you're serious about espresso, you’ll need one of the higher-end machines - they make great coffee, but they also start around $700.
> [...]
> Our machine will retail for around $400, but it's available to you guys on Kickstarter for only $200!
That was in 2012. Today, they still seem to be at the preorder stage, but their machine is now $800. [2]
