Yet another “stealth” start-up came out of hiding today with a big Silicon Valley funding.

That would be Transphorm, a power conversion technology company, that has raised $20 million more in a Series C financing led by Google Ventures and including Kleiner Perkins, Foundation Capital and Lux Capital.

That adds to $18 million already raised.

Said the Transphorm about its goals:

“Inefficient electric power conversion results in hundreds of terawatts of lost energy across the electrical grid, equivalent to 318 coal-fired power plants and costing the U.S. economy $40 billion a year. Leveraging breakthroughs in modern materials and a world-class team, Transphorm’s ultra-efficient and cost-competitive power modules eliminate up to 90 percent of all electric conversion losses.”

Here’s the official press release:

Transphorm emerges from stealth to redefine energy efficiency

Company backed by $38 million from leading venture capital firms Kleiner Perkins, Google Ventures, Foundation Capital, and Lux Capital

New approach to electric power conversion eliminates multi-billion dollar efficiency losses

Mountain View, Calif. February 23, 2011–Transphorm Inc., redefining energy efficiency with the most efficient and compact power conversion technology, emerges from stealth mode today at a private event at Google Ventures. The company announced it completed a $20 million Series C financing led by Google Ventures, with participation from existing venture investors Kleiner Perkins Caufield & Byers, Foundation Capital and Lux Capital. This brings the total capital raised from all rounds to $38 million.

Inefficient electric power conversion results in hundreds of terawatts of lost energy across the electrical grid, equivalent to 318 coal-fired power plants and costing the U.S. economy $40 billion a year. Leveraging breakthroughs in modern materials and a world-class team, Transphorm’s ultra-efficient and cost-competitive power modules eliminate up to 90 percent of all electric conversion losses. From HVACs to hybrids, from servers to solar panels, Transphorm enables significant energy savings across the grid.

“We founded Transphorm to re-imagine what enhanced efficiency in the generation and use of electrical energy can do for our economy,” said Umesh Mishra, CEO of Transphorm. “Why put up with needless energy waste in every electrical system and device, when we can quickly and cost-effectively design products that are inherently energy efficient? Transphorm’s next-generation power modules cut waste, increase efficiency, reduce system size and simplify overall product design.”

“Since we deliver a complete solution from the original materials through to the final modules, we are in a position to rapidly innovate and deliver product in quick response to demand,” said Primit Parikh, President of Transphorm. “We look forward to helping our partners open a new era in ultra-efficient and compact power conversion.”

Founded by the experienced entrepreneurial team of Umesh Mishra and Primit Parikh, Transphorm boasts world-class engineers as well as top business and manufacturing executives who will guide the commercialization of Transphorm’s technology.

“Solving the enormous problem of power waste will create immediate, long-term shared value for Transphorm’s customers and investors,” said Randy Komisar, partner, Kleiner Perkins Caufield & Byers. “It was imperative for our firm to get behind Transphorm because it is the first company with a viable, commercial-scale solution to energy losses associated with high-voltage power conversion.”

Transphorm delivers custom-designed power modules that are easy to embed in virtually any electrical system, from consumer electronics products, to industrial motor drives, to inverters for solar panels and electric vehicles, and sells these modules to power equipment manufacturers. The company will unveil its first product at the upcoming APEC conference, taking place in Fort Worth, Tex. from Mar. 6 -10, 2011.

“We recognize the need to innovate to uncover new opportunities for optimal energy efficiency,” said Toshihiro Sawa, Managing Director, Technology & Development Division of Yaskawa Electric Corporation. “The time is right to develop power conversion technologies that can cut power waste and reduce excess heat, and Transphorm provides a viable solution today.”

“It is imperative that power conversion efficiency be increased both to cut unnecessary losses and to save energy, but also to reduce waste heat which has negative impact on volume, weight, cost and reliability,” said Dr. Leo Casey, CTO, Satcon Corporation. “The innovations made by Transphorm offer an attractive solution to this problem.”

Last month, the company rolled out a revamped version of Myspace, which is owned by News Corp., publisher of the Wall Street Journal. I’ve been testing it to see what has changed and if it’s worth using. Its interface is cleaner than the old version of Myspace and I found it easy to navigate. It’s also inviting for non-members or people who’ve long-since given up on Myspace. But I can’t definitely say I like it enough to add it to my large list of social networks.

Step one of this site’s rehab was a new focus. Myspace (myspace.com) was redesigned to serve as a source of information about entertainment. People who use it can follow five categories—TV, music, movies, celebrities and comedy—that include more than 100,000 topics. News about these topics comes from sites all over the Web and is arranged on users’ home pages to show loads of information at a glance. A Discovery tab at the top of the page shows content related to trends on Myspace makes suggestions based on a user’s preferences and taste. A spokesman said the Myspace topics can be expanded, but for now, if you’re fonder of, say, books, theater or hard news, Myspace won’t be a good fit.

Step two for Myspace included making nice with its old competitor. It now works with Facebook Connect to pull in people’s Facebook “likes” and interests, which automatically generate customized Myspace pages for new users.

The final step of the Myspace redesign was its emphasis on music. The site still contains one of the largest Web music catalogs that plays full versions of songs for anyone who visits Myspace. New versions of band profile pages look more organized. And all artists with band profiles will have ReverbNation’s FanReach email product integrated into their profile to help them create targeted email campaigns for fans.

Was Myspace’s rehabilitation worth the effort? I’ve been using it for a week and it has taught me a lot more than I knew about things I care about. I had no idea that one of my favorite TV shows, TNT’s “The Closer,” recently said that 2011 would be its last season. Nor did I know that Anthony Bourdain blogs about his role as a judge on “Top Chef Masters.” These items and others appeared on my Home page after I performed the process that the Myspace site refers to as a Facebook Mashup.

The Facebook Mashup does a few things automatically for you, in addition to generating a Myspace page filled with topic-related news. A playlist is created in the Music section of your page that contains artists whom you “like” on Facebook (or whom you indicated while setting up an account). And the Videos section of the Myspace page will reflect your tastes in a list of Followed Channels related to your Facebook preferences.

The Home page can be seen in one of three views—List, Grid or Play—and icons at the top of the screen let users toggle among these views. My favorite was Grid View in the Full Grid View format, visible by clicking a small box at the top of the page.

Some of the content displayed on my Home page was mixed up. For example, a tile representing the story about Mr. Bourdain’s blog (originally posted on Celebrifi.com) displayed with it a photo of actor Tom Cruise, who wasn’t mentioned in that post. Another Tom, Tom Colicchio, chef and a “Top Chef Masters” judge, was mentioned in the post, but that doesn’t explain the mix-up.

Anything that falls into the 100,000 plus topics of Myspace’s realm can be found via a search box in the top right corner of the page, but this box is confusingly labeled, “Search People.” Though Myspace still allows users to search for and friend one another, the label on this search box is puzzling, given the greater reach of the site.

You can watch video content from Hulu.com (of which News Corp. is part owner) without jumping to a new page. And videos also come from other sources like TMZ and the NFL.

Users can earn recognition badges—icons that show up on their page—for their involvement on Myspace, and can become curators of topics, awarded on the basis of users’ involvement and how much other people respond to their activity.

This week, a Myspace mobile app was launched in Apple’s App Store, and an Android app is due out next year.

Myspace successfully reinvented itself in a way that could very well get people using it again, but Facebook’s more personalized social network may be more valuable than a rich library of entertainment content.

The video shows the evolution of tablets, beginning with the hieroglyphs of ancient Egypt, which offered good graphics but weighed a little too much for good portability. Other stops on the journey include the Ten Commandments–”Excellent durability, but zero flexibility (can’t edit)”–and the 1989 Grid tablet, with its 20-megabyte hard drive.

From there, Motorola starts taking swipes at the current competition, including the iPad, which it calls a “giant iPhone,” and the Galaxy Tab, which it says is “Android OS, but Android OS for a phone.”

As for Motorola’s tablet, it is shrouded, but a buzzing bee next to a Motorola logo would seem to confirm its use of Honeycomb, the version of Android being explicitly developed for tablets. The video ends with the text “CES 2011.”

Google’s Andy Rubin showed a prototype Honeycomb-based Motorola tablet at last month’s D: Dive Into Mobile conference. He said the device was based on an Nvidia Tegra processor, but shared few other technical details. (If you missed the talk, there’s a video of Rubin’s presentation here).

In a backstage interview with Mobilized, Rubin confirmed that Honeycomb is specifically aimed at tablets, tweaking the Android interface to be better suited to running on larger devices and take advantage of the added screen real estate.

Because by 2020 it’s likely to have been erased entirely. That’s the word from the Pew Internet & American Life Project, whose recent “Future of the Internet III” study suggests that the dawn of the mobile phone as a “primary” Internet connection will essentially obliterate the boundaries between work and home. Fifty-six percent of the Pew survey’s respondents agreed that by 2020 the formalized delineation of social, personal, and work time will have disappeared. “The 9-to-5 approach will disappear completely, with few exceptions,” ICANN Board member Roberto Gaetano told Pew. “The current separation between ‘work time’ and ‘free time’ is a byproduct of the industrial revolution, and is bound to disappear with it.”

So 12 years from now our work lives will be our lives entire?

That’s an unsettling thought. But if we’re always connected, always on the grid, then what’s to stop it from coming to pass? What’s to stop “the expansion of the work to encompass all time and all space,” as Nick Carr described it in his comments to Pew researchers. A reassertion of the same boundaries we’re seeing erased, I imagine. Otherwise we may have this to look forward to…

Said Benjamin Ben-Baruch, senior market intelligence consultant and applied sociologist for Aquent: “In 2020…a myth will develop that outside of formally scheduled activities, work and play can be seamlessly integrated in most of these workers’ lives. Employers will attempt to convince us that this is a net positive for people because we will be able to blend personal/professional duties…. However the reality will be quite different. Because we can be surveilled whenever we are ‘connected’ and especially because we can be surveilled whenever we are connected using our employer-provided devices, we can and will be controlled. Our employers will gain even more control over work-time discipline and over our lives and will be able to force even more productive working hours from us. Our lives will in fact be increasingly controlled by those who provide us with the devices that will have become increasingly necessary for us in both our work and personal lives as well as those who own and control the networks and network sites that we use and visit. Some companies will try to distinguish themselves as companies that do not actually use their power to watch and control us–but most companies will do the ‘fiscally responsible’ thing of using available technology to assert control.”
