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.
