In the above photo, Google X’s Sarah Price is showing off the original prototype in a slide while sporting the current model, which is way more refined, has a much smaller battery and can still power the glasses for a day. The next prototype — but still an early version — is below.

And finally the current version below that you can see Googlers sporting around the campus and elsewhere (I saw a pair in the wild at a Mission pub this weekend).

Tesla investor Steve Jurvetson — a partner with Draper Fisher Jurvetson — drove off in the very first Model S electric car recently and just published this video and photo to prove it on his Flickr feed.

Jurvetson has had his eye on the first Model S since the concept of the Model S was out there. Back in 2010, Jurvetson told the story to a Chicago Tribune reporter and explained that at a board meeting in early 2009 this happened:

“The policy was that only after the car was officially on sale and the price had been set could anybody reserve a Model S. . . They were about to open the meeting, so without saying a word I whip out my wallet, where I always keep one check, fill it out for the full price of the car, and then toss it across the table. Everyone was stunned.”

Of course, the Model S is now priced at a range from $50,000 to $100,000 (expect Jurvetson’s model to be on the high end of that). Here’s the video of the delivery taken recently and posted yesterday:

Those startups can be a new entrant into an existing market like Apple entering into the music market or a startup, he explained. “We believe strongly that all meaningful change comes from entrepreneurs,” Jurvetson said, adding that he currently he sees much of this change hitting industries that have largely been shielded from such disruptions.

That is reflected in the arc of DFJ’s investments in the last few years. It has shifted from initial forays into IT-related fields such as solar panels which are similar in structure to semiconductor manufacturing and energy management software to new fuels and materials as well as efficiency and lighting. As an example of bringing efficiency to IT, he compared the current centralized server model to a P2P model. With 30,000 servers, a P2P network would mean 700,000 fewer pounds of carbon dioxide, which is like removing 35,000 cars from the road.

Jurvetson spent a considerable amount of time on data center efficiency, highlighting portfolio companies such as PowerAssure which has save one customer 57 percent on their energy costs simply by turning off servers hen they are not needed. Other investments include SeaMicro, a company redesigning servers using Atom chips, which can cut energy costs by 50 percent. Currently data centers use about 3 percent of the world’s total energy consumption.

He concluded the talk with a look ahead at how the advances in computation have helped push the life sciences to a point when companies can test and build synthetic chemicals and fuels that could be the disruption that takes on the trillion-dollar chemicals and petroleum industries. Scientists can now sequence genes very quickly and can use the genetic code to build new organisms  via simulation rather than in the lab. “Biotech 1.0 is slow, like a  lab science, and Version 2.0 is more like computational sciences,” Jurvetson said.
