Fuel cell for Mobile phone

The Medis 24-7 Power Pack is portable power system designed to keep your handheld devices operational while you are on the go. The Power Pack has enough power to drive many handheld devices when the battery is nearly depleted and it will also function as a portable charger.

The 24-7 Power Pack provides sufficient energy to provide up to 30 hours of talk time to an average mobile phone or 60-80 hours of play time for an average iPod. The power is sufficient (1 watt)) to operate, and charge, multiple times, a wide range of the standard and advanced portable electronic devices in the market today.

Devices that could benefit from the Medis 24/7 Power Pack incude:

• Most mobile phones, including those with advance features, such as internet, video conferencing or TV on demand
• Dual-mode phones – Power hungry dual mode phones can make calls with either standard cellular technology or connect via WiFi or VoIP
• Smart phones and Blackberries
• iPods and MP3 players
• Hand-held video games
• Most other similar sized devices.

Medis’ power management system provides the capability of servicing a number of different devices.The supplied cable has a standard connector and different connector tips are available for most devices currently in use today.

Shoe Flash Drive Rips of Nike Design

I’m sure Nike won’t appreciate this one. A USB flash drive in the form of an athletic shoe, that obviously has the Nike swoosh on the side. Pop the toe off the shoe and it reveals the USB connector allowing you to plug the show into your USB port. Storage capacity is 1GB.

The shoe drive is compatible with both windows and Mac and measures in at 65mm w x 25mm d x 25mm h. You can buy your own shoe flash drive for about $20. This reminds me of something Maxwell Smart would use, in the remake of Get Smart. The shoe drive comes with a small chain allowing you to use it as a keychain. I wonder if Nike will even bother shutting this thing down for infringing on its trademarks.

MIT students invent bio fuel cell that generates electricity from leaves and grass for $2

A team of student researchers at MIT have developed a device they hope will generate enough electricity to recharge a cell phone in developing nations where electricity is scarce. The device is based on the concept of using biomass to generate electricity.

The device was constructed by five MIT students under the team name BioVolt for the inaugural MIT and Dow Materials Engineering contest held Tuesday, September 25. Team members include Gerado Jose la O’, Andrew Hoy, John Craven, Joseph Walish, Peter Weigele, Jungik Kim and Ethan Crumlin.

The device the team invented for the competition generates electricity from cellulosic biomass. The device is intended to generate enough electricity to charge a cell phone in developing countries. Team members say that the current power output of the device would take about six months to recharge your cell phone.

However, BioVolt is quick to point out that the materials in the device only cost about $2 to obtain and the biomass "fuel" can be found everywhere in nature as leaves and grass clippings. The team members say that multiple units could be connected together to increase power output and that refinements in the design of the device could yield a 100 times increase in efficiency.

The device uses anaerobic organisms to digest the cellulose and converts the material into electricity and water in a microbial fuel cell. The fuel cell contains two sides and in one side the micro-organisms break down the cellulose to component sugars.

According to the BioVolt abstract the sugars are then oxidized by bacteria and the resulting electrons are respired to a graphite anode. Protons are liberated by the oxidation of sugar, which pass through an electrolyte membrane and react with electrons and oxygen in an air cathode, which yields water and completes reactions needed to sustain electrical generation.

The BioVolt team won the first prize in the design contest and took home $5,000. The BioVolt bio fuel cell is similar to the bio fuel cell invented by researchers at Oxford in that the Biovolt cell doesn't require expensive platinum as a catalyst either.

Cool! PMP from China with NES

Folding Chinese PMP rocks NES emulation

Filed under: Portable Audio, Portable Video

It seems like adding a folding screen actually made this PMP larger rather than trimming any size, but other than that, the YDP-G68 pictured here actually seems pretty decent -- you're looking at a 2.8-inch screen, 2GB of internal memory with SD expansion, MP3, WMA, AAC, ASF and MP4 support, FM radio, TV-out, a 1.3 megapixel camera, voice recording, NES emulation, and support for "ten thousand" calendars. No word on price or whether we'll see this bad boy in the States, but seeing as the minimum order is listed as 200 units, you'd better have a lot of sucker friends to get your hands on one.

Delayed shipment

Asus Eee PC Shipments Get Delayed Sourabh Kalantri | Sunday, September 30, 2007 5:55 AM Average Story Rating: Delays and affordable laptops continue to go hand-in-hand; this time Asus wants to improve its Linux-based application suite.

The Eee PC sub-notebooks were initially excepted to make it to retail markets in second-half of September 2007.

Asustek, the makers of the Eee PC laptops, wants to improve its software applications which are bundled with these systems. They've decided to offer improved Linux-based application suite on the Eee PC.

As a result, the official launch of the Eee PC has been postponed. It's interesting to note that the $400 scheme on the OLPC laptops goes live on 12^th November 2007. Under this scheme, US and Canadian buyers have to pay $399 for an XO laptop created for the third world – and for each one sold to them, another will be given for free to a child in a developing nation.

The availability of the Eee PC will more-or-less coincide with these XOs.

The price-tag on the Eee PC by Asustek Computer will continue to remain the same, despite the provision for added software. For more info on the pricing, please refer to our news story here.

Asustek plans to ship 200,000-300,000 Eee PCs by the end of this year.
