Next time your phone runs out of battery, just grab it with your hand.

Researchers have developed a way to turn body heat into electricity meaning your mobile will never go dead again.

Power Felt can keep your phone going for up to 20 per cent longer just through the power of touch.

Wake Forest graduate school student Corey Hewitt holds of a sample of Power Felt. It converts wasted body heat into electric current, and could be used to recharge mobile phones simply by holding them.

Mobile users can even sit on their phones to make the ‘connection’ - passing electricity through their own body to the device.

The technology has been created by Professor David Carroll of Wakeforest University’s Centre for Nanotechnology and Molecular Materials in the US.

He said that it could be the first wave of inexpensive ways to produce electricity that were far more affordable than current renewables such as solar, which was being held back by the high cost.

Power Felt is also extremely versatile and could provide emergency electricity for a radio or a torch meaning it would be vital during power outages.

Professor Carroll said he began his experiments after finding there was no naturally occurring material which was able to conduct electricity in the way he wanted that was affordable and flexible.

Instead he and his team used nanotechnology to put tiny carbon nanotubes into miniscule plastic fibres and made them look like a fabric.

Explaining the mechanism worked, Professor Carroll said: ‘If you grab one end of a bar of metal, the electrons that heat your hand become warm. 

‘As they warm, they seek out the cold spots, which would be the other end of the bar. So (the electrons go) rushing down to the other end of the bar.

The 'power felt' could mean gadgets recharge from the heat generated from human skin - so simple holding one, or even sitting on it, could recharge them.

‘So I have an excess of electrons on one side, and a depletion of excess electrons underneath my hands, so I have a voltage between the two which is called the thermal voltage. And that’s what Power Felt generates.’

Even if there is no big temperature difference Power Felt can still pick up power from noises such as the vibration of the car, he added.

So far he has already made a shirt that charges batteries, but the first way the technology could be used is toys.

Sports clothing could also have a range of gadgets to monitor a person’s performance built into it, all powered by the individual’s own electric charge.

Professor Carroll told News Observer: ‘Kids absolutely love this stuff because you can put it all places and get power. 

‘You run little motors and stuff. ... You can make little toys run. You can make little cars run around from a pad.

‘Those are the fun things, because kids begin to imagine really wild places to start using this. ... they’re interested in how it works, but they’re more interested in what can they do with it. 

‘It seems to be a property of children: ‘Can I put it here, or can I make it do that?’ They kind of want to fiddle with it, and that’s great.

‘There’s loads and loads of science behind this, but that’s not the fun part of Power Felt. The fun part of Power Felt is playing with it.’

HOW TO SEND FAX FROM COMPUTER TO FAX MACHINE -WINDOW XP

Windows XP can send, receive, track, and monitor faxes without an external fax machine. However, the fax component is not installed automatically during Windows setup. This step-by-step article describes how to install, enable, and configure the fax service in Windows XP.

Requirements

· A computer that is running Windows XP and is equipped with a fax modem that is connected to a telephone line

Most modern modems are fax modems. If you are unsure whether your modem can send and receive faxes, see the documentation that was included with your modem.

· The CD that you used to install Windows XP

Notes

· You do not need a separate fax machine to send and receive faxes with Windows XP fax service.
· If you plan to transmit printed material by fax, you must have a scanner. If you plan to create faxes electronically, you do not need a scanner.

Install the fax component

To install the fax component, follow these steps:

1. Click Start, and then click Run.
2. Copy and paste or type the following command in the Open box, and then click OK:

appwiz.cpl

It may take several seconds for your computer to compile a list of programs. The Add or Remove Programs dialog box opens.

3. Click Add/Remove Windows Components to the left of the list of programs to start the Windows Components Wizard. This takes several seconds.

4. In the Components list, click to select the Fax Services check box, and then click Next. Setup installs the fax services.

5. If you are prompted, insert the Windows XP CD, and then click OK.

If the Welcome to Microsoft Windows XP window opens, click the X in the upper-right corner to close it.
6. Click Finish, and then click the X in the upper-right corner of the Add or Remove Programs dialog box to close it.

The fax component of Windows XP should be installed now. If you have problems installing the fax component, go to the "Next Steps" section.

The next step is to configure the fax service. To do this, go to the "Configure the fax service" section.

Configure the fax service

To configure faxing capability in Windows XP, follow these steps:

Step 1: Configure the cover page, select a modem, and enable the fax service to send and receive faxes

a. Click Start, point to All Programs, point to Accessories, point to Communications, point to Fax, and then click Fax Console.

The Fax Configuration Wizard starts.
b. If you are prompted, type the area code or city code of your present location, a carrier code, the number that you must dial first to dial out, and the telephone system that you are using (Tone or Pulse), and then click OK.

If the Phone and Modem Options dialog box is displayed, select your location (if more than one exists), and then click OK.

c. Click Next, type the information that you want to appear on your fax cover page, and then click Next.
d. In the Please select the fax device list, click the modem that you want to use.
e. If you want to disable the ability to send faxes from this computer, click to clear the Enable Send check box.

Note By default, the Enable Send check box is selected.
f. Click to select the Enable Receive check box if you want the computer to receive faxes.

Note When this check box is selected, you can click Manual answer if you do not want the computer to automatically receive faxes. By default, automatic answering is enabled.

g. Click Next.

Step 2: Enter TSID and CSID information and configure printing and storing preferences

a. Type the Transmitting Subscriber Identification (TSID) that you want to use in the TSIDbox.

Note The TSID is mandatory in some areas. This identification information typically appears in the header area of a fax that you receive and can help you recognize the fax machine where the fax originated. The TSID typically includes the sender's fax number and business name.

b. Click Next.
c. Type the Called Subscriber Identification (CSID) that you want in the CSID box.

Note The CSID text that you enter appears on fax machines that send faxes to you. For example, if you enter "123 Fax", a machine that sends you a fax might display the message "Sending a fax to 123 Fax" while sending.

d. Click Next.
e. Click to select the Print it on check box if you want each fax that you receive to be automatically printed. When you select this check box, you can select a specific printer to print the fax.

f. Click to select the Store a copy in a folder check box if you want to archive a copy of each fax. When you select this check box, you can specify the storage location for the fax copy.

g. Click Next.
h. Confirm the configuration settings in the Configuration Summary list, and then click Finish.

The Fax Configuration Wizard closes and the Fax Console window opens. The computer is now configured to send or receive faxes.

We have heard of highways being used as runways in some countries. But this is the first time I have seen roads crossing a runway and road traffic being stopped by a traffic light while an aircraft takes off or lands!
