everything for free. Well, now we
might have something like that in
reality as well. With this latest
development, you can power your low
energy electronic devices for free and for a
very very long time.
Freevolt is the technology that could
absorb energy from the radio waves and
convert it into useful and long lasting
powering source. And since we are not
going to run out of these electromagnetic
radiations anytime soon, this technology
might just be a brilliant piece of
innovation.
Now, this is not the first attempt at
creating a technology of such sort but
efforts had been going on since many
years on this front. Interestingly, there is
an app that helps you see all the wireless
signals flying around you.
The product of the Drayson
Technologies, however, is the first
commercially available technology of such
kind that aims to cut out our energy
dependence on the conventional sources.
The Freevolt system has a multi-band
antenna that extracts energy from the
surrounding within 0.5- 5 Ghz range and
transmits it through an "ultra-efficient"
rectifier which converts this RF energy
into usable DC energy. The DC energy is
stored in a power management module for
later use.
The available Freevolt system can produce
about 100 μW in a location flooded with
RF energy. Now, this energy might sound
too low for your regular electronics, but it
can power the sensor based system of
your home, like a smoke alarm or a low
power security cam.
But, this is just a start. If we are able to
harvest the energy from the
electromagnetic spectrum, with the ever
advancing technology, it shouldn't be a
problem to amplify it to create a
substantial power system.
Drayson is now working on flexible
models of Freevolt to widen scope
beyond sensors and for that the company
is sharing its patents and ready to offer
technical assistance to its takers. Drayson
has also developed CleanSpace, an air
pollution monitor that exclusively works
on Freevolt.
CleanSpace keeps tabs on the air quality
specifically carbon monoxide and
feedbacks the data to your smartphone via
Bluetooth. The app gives you points in the
form of CleanMiles feature that
encourages users to develop a healthy
lifestyle by walking and cycling. To
appreciate your efforts towards reducing
pollution, Drayson allows you to exchange
these earned CleanMiles for gifts by its
partners like Amazon.
The CleanSpace Tag, however, is available
in the UK for now through a crowdfunding
campaign. You can get your own Freevolt
system with CleanSpace for £55.
As for our opinion, the technology seems
quite promising and if escalated to bigger
proportions, it could somewhat be an
immediate solution.
