REVIEW: AlertMe Starter Energy monitoring kit

In these penny-pinching times we need every bit of help we can get to keep our bills down. Is AlertMe the solution to keeping those electricity bills in check, or a needlessly expensive alternative to switching off the lights before heading on out for the day?

Nokia looking to patent self-recharging phone batteries

Nokia are looking to file a patent for a mechanism that would allow phone batteries to recharge themselves when out and about by collecting the kinetic energy generated by movement. It'd work like this: the heavier components within a phone…

Turbine City concept – Gallery

It gets pretty windy in Norway apparently. Well, windy enough for On Office's idea for a city built within wind turbines not to sound completely ludicrous anyway. The concept here is that with turbines growing in size to accommodate our…

Waterless washing machines to hit the market next year

To be fair, “waterless” is a slight exaggeration, but only slight because a company named Xeros has managed to develop a washing machine that uses just 90% of the water used by a normal houselhold unit.

This utility room game-changer employs reusable nylon polymer beads to wash your undies. They clean the clothes faster, using 30% less energy and each cycle only requires a single drop of detergent too. What’s more, expensive eco-enemy tumble dryers need less time because you’re linen will be less wet too. Therefore saving a few inches more planet. Sounds pretty marvelous really.

The trick has been working out a way to get the beads from your togs at the end of the wash but, now that’s sorted, Xeros reckon they’ll have commerical units in hotels and other such large operations by the end of the year.

And if that hasn’t got your juices flowing green, then check this – if these nylon polymer machines were as standard in the UK, it’d be the equivalent of taking 2 million cars of our roads. Where do I sign up?

Mobile phones and gadgets to charge themselves?

What if you never had to plug any of your gadgets in to charge them ever again? No stray wires running around your walls, no need to remember to pack numerous chargers when going on holiday and of course there are the financial and ecological benefits as well.

Well, this could well become a possibility. Nokia has got their boffins in Cambridge working on a technique whereby a phone can remain in standby mode and effectively charge itself using just ambient radio waves.

I’m no scientist, but I’ve done the research and I understand it as thus:

Waves in the air, such as Wi-Fi, radio, television and so forth can be harnessed and converted into enough juice to power your gadgets.

The system needs a bit more developing though, currently the boffins are only able to gather between three to five milliwatts of power and they need this figure to be more like 50 milliwatts in order for it to work in practice.

If they do manage to master this system, the possibilities are pretty immense. On the flip side, how scary is it that, potentially, there is enough electricity floating about in the air to charge mobile phones? How our brains don’t get frazzled remains a mystery to me.
