Outside the Ordinary Uses

What are radio waves?If you can’t see it, how do you know it’s there?The difference between radio waves and God:

• Whilst radio waves are invisible to the human eye, they carry everyday information thousands of miles every day, drastically changing the way that we as humans, act.

• Radio waves don’t just have to be used in radio. Whilst radio waves seem to be primarily used in this way, they actually have many different forms in our world – wireless technology in mobile phone to MRI scans and radiotheraphy in hospitals.

• God hasn’t yet cured cancer – radio may well do.

Radio waves work by transmitting information on a specific frequency. If you were to tune a receiver to this frequency, you could then receive whatever information being transmitted by the set.

This PowerPoint presentation covers the uses of radio waves outside of the typical use – listening to them, via an amplifier.

The recent developments in technology mean a lot more can be done with a simple piece of

technology. 5 years you could connect a device to your iPod, which would then transmit radio waves

into the ether – letting you play your music through an analogue radio (as long as you could find a free

wave!).This technology had limitations – if you were

driving along a bumpy road on a cloudy day, it would be very difficult to keep a constant stream from the iPod. Using an FM frequency meant that there would also be difficulties in built up areas.

So what’s changed? Why can we do so much now that we couldn’t before? Why does the Gadget Guy’s in-car pasta maker (in the Toyota advert) get beaten by a car that can pick up music directly – and wirelessly, from a mobile?

Whilst this presentation will focus on a few main uses, there many uses for radio waves, some of which are listed above

Radio – A cure for cancer?

John S. Kanzius (March 1, 1944 – February 18, 2009)

The main issues surrounding cancer cures is the difficulty of destroying the cancer cells – without damaging healthy ones.

Radiation therapy specifically has this issue – but testing and cases show that it can be used to cure cancer. The danger of radiation therapy, and the reason it is so frequently used in conjunction with chemotherapy is the damage to healthy , surrounding healthy cells. This can sometimes cause more damage than help.

John S. Kanzius created the concept of radio waves treating cancer cells. Unlike chemotherapy and radiation therapy, radiotherapy has the potential to treat surrounding cells – and not damaging the healthy ones. This manipulation of radio waves is a massive development for medical science.

Radio – The end of Bees

Scientists say that the end of bees will coincide with the end of the world, but nobody really know what is killing them. Or do they?

A 2010 study by Punjab University has suggested that mobile phone radiation could be what caused the 17% drop between 2009 and 2010 in the population levels of bees. After 3 months of the study the hives population had drastically dropped, and the Queen’s egg production had more than halved.

Because of the way that bees use cryptochrome for navigation. Radio waves used in mobile phone technology could be confusing the bees navigation; it stops the bees being able to sense the earths magnetic field – and as such, confuses their directions.

Radio – Wireless Technology

A computer, mobile (or whatever device used for wireless access) transmits data via a wireless signal through an antennae.

A router is then used to receive and decode this signal from the device. This then connects to the internet using a cabled Ethernet connection.

Wireless technology can be used in many ways. Primarily it allows for wireless internet connection but wireless technology is actually used is much of human technology. A cordless phone, be that landline or mobile uses radio waves and wireless tech. A remote control for a television uses this technology – even a car key uses it to connect to the car’s central locking system, and allow the doors to be unlocked.

Radio – MRI scans

Radio waves use powerful magnets and radio waves to create visual images. Not only can these be used for brain scans, a similar replication of the technology has been used to create the full body scanners now used in some airport securities.

The 2003 Nobel Prize for Medicine was awarded to Paul Lauterbur and Peter Mansfield for this technology, as it can show tumours at an earlier stage than previous technologies.

Cancerous cells and tissues emit the same signals as ordinary, healthy cells. However their signal is emitted for longer – thereby showing which tissue needs therapy and which doesn’t.

Radio – Developing Solar Power

In September 2011 Array Converter announced that they were developing a technology that would better convert solar energy – using radio waves.

Solar energy currently uses inverter technology, switching DC to AC in order for it to be fed into the electronics grid. There are normally about 12 solar panels to every 1 inverter.

By using amplitude modulation, the same technology used in radios, it is hoped that this radio technology can then be used to convert the direct current in the panels into the current used in the grid.

Not only is this technology much cheaper in the long-term, it actually works out fiscally beneficial in the short term. Ordinarily with solar energy, benefits are only reaped far down the line – using amplitude modulation cuts “overall equipment and installation costs”.

Radio – Model Airplanes

All radio controlled toys, such as model cars, planes and boats have four thing in common:

1. The Transmitter2. The Receiver3. The Motor4. The Power Source

The transmitter controls the toy – it works as a remote. This sends the receiver radio waves. The receiver is the circuit board within the toy. This receives the signals from the transmitter and then activates the motor, which creates the motion in the toy – turning the wheels of the car or spinning the propellers on a plane.
