FREE energy from the air! Sounds like a fantasy, but that is what the entrepreneur and former science minister, Lord Drayson has unveiled at London’s Royal Institution.He claims that a technology called Free-volt can be the power source for the “Internet of things”, allowing low- energy devices, from wearables to sensors, to operate without being plugged in.
The technology involves harvesting radio-frequency energy from existing wireless and broadcast networks, from 4G to digital television. It doesn’t require any extra infrastructure; it doesn’t require us to transmit any extra energy; and it’s recycling the energy which isn’t being used at the moment.
The technology, which has been patented, could now be used by organisations such as supermarkets which are preparing for the next phase of the Internet, where billions of small, cheap sensors are providing Online data about their operations.

New dad, Mark Zuckerberg to give back
LAST Tuesday, Facebook CEO and his wife Priscilla Chan honoured the birth of their daughter, Max, by committing to spend 99 per cent of their Facebook shares, some $45B worth at current prices, on humanitarian projects over the course of their lifetime.
But now, some are raising questions about the unusual structure they have created to transfer their money.
To put it simply, Zuckerberg is not giving 99 per cent of his wealth to charity; he is pledging $45B in Facebook shares to a new private limited liability company (LLC) called ‘The Chan-Zuckerberg Initiative’. Most billionaires, like Bill Gates and Warren Buffet, when they give to charity, give shares or money to a non-profit, a Foundation or a charitable trust. So, why would Zuckerberg choose to disburse his money through an LLC rather than a Foundation? Industry watchers say there are three possible answers: Lobbying, investing and disclosure.
Lobbying
Non-profits are limited in the amount of money they can spend on lobbying, and they cannot give to political campaigns. Zuckerberg’s new LLC can do both of those things, and will likely seek to fund political change. According to the letter to their daughter Zuckerberg and Chan released on Facebook Tuesday, the initiative will participate in policy and shape debates.

Holiday lights, gadgets killing your wi-fi
IF you want super-fast Wi-Fi in your home, you may want to turn off your holiday lights.
While problems with network congestion and infrastructure take most of the blame for slow broadband, devices such as baby monitors and home phones can interfere with your Wi-Fi because they compete for frequency.

Still, the good news is that a few simple changes to the location of the router and other devices can lead to a noticeable improvement in performance.

Here are some tips from the regulator to maximise your Wi-Fi speed:
1. Restart your router: It can do a world of good to restart your router when you’re having connectivity troubles. This allows it to search for a new channel that isn’t being used by other devices.
2. Move your router away from electronic devices: Halogen lamps, electrical dimmer switches, stereo or computer speakers (and Christmas) lights have all been known to cause interference to broadband routers. Keep your router as far away as possible from other electrical devices, as well as those which emit wireless signals such as baby monitors.
3. Move your router to a central part of your home: Walls and furniture can act as obstacles to your Wi-Fi signal. Power cables running through the walls and floor can also create interference. Your best bet is to put your router on a table in the centre of your home, and keep it away from other devices.
