Turn Your iPhone Into A Radio Station

How do you turn your iPhone into a radio station? Simple. Use Wahwah. :-)

Many music lovers and mobile sharers have had certainly thought of this idea in the past, but then it seemed technically difficult and legally risky. But things will now change, thanks to Wahwah.fm, an iPhone app that can distribute the real-time music you're listening on your mobile.

Wahwah.fm introduces the concept of listening to your music and broadcasting it at the same time. Pretty cool huh? :-)

With Wahwah.fm you can create your own music radio station by setting what music you are currently playing on your iPhone into public. This way, other wahwah.fm users can tune into your broadcast and hear the exact same music you are listening to.

You can first create playlists from the tracks in your iPhone or SoundCloud, then start the broadcast , listen, and deliver the same music at the same time to others so that they can listen to what you are listen. It's a powerful concept of music sharing.

Want more? The application will also provide a geolocation functionality that will connect directly to broadcasters close to your home for you to monitor what they're listening to.

Sharing functions and comments is also available.This is indeed a very exciting app that I am eager to test, but while it seems like a novel idea, many still raise some questions. From the technical point of view, streaming music over the network using your smartphone requires a good connection and will of course consume bandwidth, something that could be quite unpopular with the telecom operators, which could limit or prohibit this kind of use. They may also find a new way to charge for this option. The other question is it's legality: publicly broadcasting music without paying royalties will raise many legal arguments, which may eventually spin out of control.

In the meantime, treat yourself with this app while it's still available. :-)

Mini-Turbine Uses Blood To Produce Energy?

The title sounds almost like Fantastic Voyage and Innerspace, and if we were close to April 1, you may have doubted the validity of our headline for today. But this project is deadly serious, as it originated from a country renowned for its expertise in precision mechanisms.

The idea is simple: blood flow and pressure are a potential source of energy. Why not then take the good old principle of the dynamo or the water mill, and upon tweaking this idea, why not consider installing a micro-turbine in the body to produce electricity? Hmmm.

No, don not think that the energy produced by this "microturbine" will be enough to charge your iPod or advance your Prius Hybrid on the road, but the energy produced, up to about one milliwatt, can be enough to supply electricity amounting to an equivalent of ten pacemakers. Whoa. This looks promising. Very promising indeed. Imagine this, using a tiny turbine installed in a blood vessel, researchers could generate the microwatts needed to keep implanted medical devices ticking. With proper development, this could then provide a means for patients with pacemakers to get rid of constraints and batteries to become completely autonomous and self-sufficient in energy: How's that for innovation? :-) As the heart beats, it generates power for the patient's device, with its own energy. Potential uses of this energy may be for implanted medical devices like pacemakers, blood pressure sensors, drug-deliver pumps, glucose meters, or neurostimulators, all of which need just a tiny amount of juice to continue operating.

This fantastic concept was presented recently at the International Conference on Medicine and Biology Microctechnologies in Lucerne Switzerland by a team of researchers at the University of Bern. However, it is not without some risks, since its presence in the bloodstream can potentially cause blood clot coagulation. Ther work is not finished for its creators, and there will be many stages of development before the device will be safe and operational for public use.
