A UK company has launched a new device that allows users to cut-off their water supply at the flick of a switch, drastically reducing wasteage and giving a significant boost to water conservation efforts.
Instead of scrabbling around looking for the stopcock, the new Surestop device allows users cut supply instantly, saving water loss, and consequent damage, whilst giving householders direct control over water consumption.
Now the company hopes to expand into areas crippled by drought, where water conservation is a pressing priority.

Go on, admit it - how many times have you forgotten to water your houseplants? Maybe you’ve even left some of them so long they’ve withered away to nothing. In fact, the chances are that if a plant could talk the thing they’d be most likely to say would be WATER ME!
Well, thanks to a new device, your long-suffering plants will now be able to do just that. What’s that you say - a talking houseplant? Well, not exactly, but thanks to researchers at New York University’s interactive telecommunications program plants will now be able to to tell owners when they need water or if they’ve had too much via the social networking service Twitter.

Tremont Electric has launched a portable energy generator that allows users to charge handheld electronic devices simply by going for a walk.
The nPower PEG, launched at last week’s 2009 CES event, works on the principle of electromagnetic induction to create a 100% renewable energy source for everything from iPods to mobile phones. To get a charge, users simply connect the PEG to their mobile device and lay it vertically, either against their hip, or in a bag, while they go for a walk or a run.

A team of designers have created solar power generating sunglasses capable of charging portable electronic devices on-the-go.
The SIG, or ’self-energy converting sunglasses,’ contain integrated dye-solar cells and can be simply connected to the power jack in an iPod or PSP, allowing devices to be charged without the need to hook up to the mains supply.

A UK engineer has invented a device that harnesses wave power to pump sea water uphill, from where it can flow downhill to create hydroelectricity, raising hopes of a cheap, abundant source of renewable energy.
In trials, the device, called the Searaser, has pumped water more than 160ft above sea level, using little more than the natural motion of the waves. There are now plans for a much larger version, capable of pumping to a height of more than 650ft.
Inventor Alvin Smith reckons that each full-size device would be able to pump enough water to supply electricity to 470 homes. He also calculates that a fleet of 43,000 could generate enough power for a staggering 20 million households.
