An electric fuel cell powered by your own body:CHANNEL YOUR PERSONAL POWER

Here’s a new one. An electric fuel cell 

powered by your own body. We’ll take a look, today on 

Engineering Works!

•  Lightweight, compact devices could power medical devices. 

• Eat a Snickers bar to power up.

                                                         These days, everybody’s looking for new sources of electricity. All our portable electronics  -- iPods, cell phones, laptops -- they all need good batteries to keep playing or talking or 

 calculating. The batteries we have really aren’t that good. They’re not much better than the voltaic pile battery Alessandro Volta invented more than 200 years ago.

Engineering researchers are looking into a new power source. They’re looking, well, into themselves. 

 

It’s pretty simple – and complicated, all at the same time. Imagine a small chip – called a biofuel cell – that uses sugar and oxygen to generate electricity. Now, imagine that biofuel cell is implanted in your arm. The oxygen and sugar is in your blood. Can you see it now? Electricity. It’s always there and always being recharged. Running low on power? Grab a Coke or a candy bar. 

The engineers really aren’t interested in a new way for you to power your iPod. Not yet, anyway. They’re looking for lightweight, compact, dependable ways for astronauts to power things like medical sensors in space. Now, they’re getting ready to send one up in a satellite to see how well it does in orbit. No people. Just tiny tanks of sugar and oxygen. The people will come later, they hope.

Well, our iPod sounds like it’s going flat. Guess we need to grab a Snickers bar. See you next time.  

sony's show for latest gadget with new technology :Sony Expo Showcases Latest Tech

The annual Sony Hawaii Expo was held this week at the Ala Moana Hotel Hibiscus

 Ballroom.    Highlight of this year’s Sony Expo was the desktop Sony OLED flatscreen TV (shown above). The hallmark of this high tech wonder is its small size and crystal clear high definition picture. The screen itself is thinner than a compact disc jewel case.

Another hyped product at the Sony Hawaii Expo is the new Sony Rolly MP3 player. It is a new portable device that is shaped like a little barrel and moves to the beat of the music. The speakers on this device are positioned at both ends and open up with winglike flaps on each end. The device will not be marketed in the U.S. and is aimed only at consumers in Japan. If it were sold in the U.S. the price would be at around $400.

The Sony Rolly MP3 player. Sold only in Japan.

Face recognition “smile” technology for Sony Cybershot cameras were also a new this year. The new Cybershots can sense when a person smiles and fires only at that time. People were happily smiling for the demo at the Sony Cybershot booth. There were many other Cybershot digital still and video cameras that were also on display for consumers to play with.

I was most interested in the small super zoom, SLR-like cameras that I may want to get in an effort to find a capable SLR-like digital camera without all of the weight and bulk.

Last year’s hot product, the Sony Playstation 3 was almost like a has-been this year. Yes, there were displays of the venerable Playstation 3 for people to use, but the crowds around those stations were not very big. Sony is still marketing the Playstation 2 which is still the most popular game console of all time, despite Nintendo running away with the market lead on their new generation Wii product.

I am still interested in perhaps getting a Sony PSP, mainly for the fact that it can surf the web with its wireless internet feature. Another wifi device that was touted last year, the Sony Mylo, was nowhere to be seen this year. Sony still sells the device.

HDTV are the big products Sony is pushing this year as the Expo was dominated by flatscreen high definition sets all over the place. Going hand in hand with that were several Sony Blu-Ray HDTV DVD players. the pictures on the sets and from the players are incredibly clear.

People clamor around the latest Sony digital cameras.

Don’t know if I am ready to sink money in either of these technologies, especially Blu-Ray since it is locked in a format war with the rival HD-DVD. Beta vs. VHS all over again. I’ll wait for the dust to settle on this one.

Overall the Sony Expo was a great little venue to check the latest technology from one of the most popular electronic companies on the face of the earth.

Apple rolls out new iPods, social iTunes

There were few surprises at Apple's annual music event Wednesday, but as usual there are new iPods for the holiday season and a new version of Apple TV.

Here's a quick recap of what Apple CEO Steve Jobs announced Wednesday in San Francisco. Check here for a replay of our live coverage of the event from earlier in the day.

• Apple released a new version of iOS--iOS 4.1--that fixes bugs and brings the previously announced Game Center API for developers to use in building social-networking games. Also, iOS 4.2 will be released later this year, which will unify the software on iPhones and iPads as well as stream music to other devices over Wi-Fi.

• Three new iPods were announced: an iPod Shuffle that ditches the previous no-button style in returning to a more classic look; a smaller iPod Nano that now has a touch screen but can no longer play video; and a thinner iPod Touch that has most of the features first introduced on theiPhone 4. The new iPods will be available next week.

• Apple announced iTunes 10, available immediately, which comes with a new logo and a social music service called Ping that lets you see what your friends are listening to and make comments and recommendations.

• A much cheaper and smaller Apple TV will ship later this month as Apple tries to revive interest in what Jobs has long called "a hobby." It will cost $99, and users can rent HD TV shows from iTunes as well as other partners, such as ABC and Fox. They can also access Netflix's streaming service from the box.
