Pagination comes to Google Docs

(Cross-posted from the Google Docs Blog)

Exactly one year ago, we launched a new version of the Google document editor, created from the ground up to take advantage of the latest capabilities in modern web browsers like Chrome. In particular, we baked in a way of supporting text features that aren't natively included with browsers—for example, we added a ruler for controlling the margins, text that wraps around images to create eye-catching docs and discussions for a more collaborative editing experience.

Today, we're doing another first for web browsers by adding a classic word processing feature—pagination, the ability to see visual pages on your screen. We're also using pagination and some of Chrome's capabilities to improve how printing works in Google Docs. Pagination is rolling out now and should be available to everyone by the end of the day.


Pagination adds visual page breaks while you're editing your documents, so now you can see how many pages of that report you've actually finished. Because we're able to show you individual pages, we can improve the way other features work too: headers now show up at the top of each page instead of just at the top of your doc, manual page breaks actually move text onto a new page and footnotes appear at the bottom of the pages themselves.


If you prefer editing documents with a continuous layout, you can hide page breaks by selecting the "Compact" document view from the "View" menu.


Pagination also changes what's possible with printing in modern browsers. We've worked closely with the Chrome team to implement a recent web standard so we can support a feature called native printing. Before, if you wanted to print your document we'd need to first convert it into a PDF, which you would then need to open and print yourself. With native printing, you can print directly from your browser and the printed document will always exactly match what you see on your screen.

For now, native printing is only available in Google Chrome, but we're hoping other browsers will implement the same web standard so everyone can have the best possible printing experience with Docs.

Pagination and native printing are great examples of how modern browsers are making it possible to take the best parts of the desktop experience and bring them online. Please share your feedback on the Google Docs forum.

Investing in the world’s largest solar power tower plant

Posted: 11 Apr 2011 04:04 PM PDT

We've invested $168 million in an exciting new solar energy power plant being developed by BrightSource Energy in the Mojave Desert in California. Brightsource's Ivanpah Solar Electric Generating System (ISEGS) will generate 392 gross MW of clean, solar energy. That's the equivalent of taking more than 90,000 cars off the road over the lifetime of the plant, projected to be more than 25 years. The investment makes business sense and will help ensure that one of the world's largest solar energy projects is completed.

We need smart capital to transform our energy sector and build a clean energy future. This is our largest investment to date, and we've now invested over $250 million in the clean energy sector. We're excited about Ivanpah because our investment will help deploy a compelling solar energy technology that provides reliable clean energy, with the potential to significantly reduce costs on future projects.

Power towers, which have been successfully demonstrated in the U.S. and abroad at smaller scale, are based on a relatively simple idea. The technology works by using a field of mirrors, called heliostats, to concentrate the sun's rays onto a solar receiver on top of a tower. The solar receiver generates steam, which then spins a traditional turbine and generator to make electricity. Power towers are very efficient because all those mirrors focus a tremendous amount of solar energy onto a small area to produce steam at high pressure and temperature (up to 1000 degrees F). Think about burning a tuft of grass with a magnifying glass, only multiplied by thousands (or the original application: Archimedes' heat ray that allegedly used mirrors to burn enemy ships!).

Several large solar projects are in the works in the sunny Southwest (and around the globe), but Ivanpah will be the first solar power tower system of this scale. The Ivanpah Power Tower will be approximately 450 feet tall and will use 173,000 heliostats, each with two mirrors. The project is being constructed by Bechtel, a major engineering firm. Construction began in October 2010, and is projected to finish in 2013.

The Ivanpah project will also be financed by NRG and with clean energy technology loan guarantees provided by the U.S. Department of Energy. We hope that investing in Ivanpah spurs continued development and deployment of this promising technology while encouraging other companies to make similar investments in renewable energy.
