The experimenters on alt.coffee who took temperature measurements of the Silvia discovered that when the heating-element light is off (which means it's ready to pull a shot of espresso), the temperature can vary by as much as 40 degrees. This amount of variation makes consistently good espresso a nearly impossible dream. But because the Silvia had so many other good qualities (including ease of tinkering), the alt.coffee gang decided not to abandon the machine. Instead, they compensated for the shortcoming by developing the temperature surfing technique Glanville had taught me.

I don't know what is up with Gizmodo but they have been focused on the coffee lately. This time they modify an espresso machine to give a better cup of espresso. Go the previous link to check out the full details.
