New light technologies are already shipping with the new Google Glass, but what about what you might not see in the video below?

We’re talking about the upcoming liquidmetal technology.

According to a report from Bloomberg, Google is working on a new light source for Glass 2, but there’s no word on when this will be released.

The report states that liquidmetal will be a light source that “is a more efficient and lightweight alternative to the traditional glass lens.”

Google has yet to comment on the rumor, so we won’t know for sure until it happens.
