In this week's World Tech Update we're back at the 2010 Consumer Electronics Show with more news that we didn't get a chance to show you last week. We start the show with new automotive technology from Ford that turns a car into a mobile hotspot and integrates two popular web applications. Tune in to find out what they are.

MSI showed off two prototype dual screen netbooks at the show and they could hit the market by the end of this year. The 10.1-inch and 7-inch devices both have touchscreens, run Windows 7 and have Intel Menlow microprocessors.

Audio company Klipsch debuted its LightSpeaker, a wireless speaker that incorporates an LED light. The light can replace a 65 watt bulb and the speaker has good range, solid bass and good output for its size. Watch World Tech Update for some sample audio.

One of the problems with conventional laptop screens is that they are difficult to see in direct sunlight, but a screen under development by startup Pixel Qi boasts good readability in direct sunlight and very low power consumption. We'll show you one of the first products to use the screen, the Smartpad e-book reader from Notion Ink Design Labs.

At CES this year many of the largest technology companies were boasting their green credentials. Environmental group Greenpeace used CES to launch the latest version of its Guide to Greener Electronics. It praised HP, but criticized Microsoft, Samsung, Dell, Lenovo and LG Electronics.

CES isn't just about electronics and gadgets, but celebrities too and we ran into a few either promoting products or browsing the show floor. In last week's program we showed you Taylor Swift performing at Sony's news conference. In this week's show we have Brooke Shields, Whitney Port, comedian Sinbad and Lady Gaga in her new role as Polaroid's creative director.

World Tech Update is a recap of the week's technology news. To learn more, follow the show on Facebook and Twitter.
