Press 'pause' to prevent pregnancy

Everyone likes to daintily skirt around the problem of population when talking about sustainability. It's off-limits and taboo, and the solutions are hard to get everyone to agree on -- though, we at EcoGeek have always maintained that the condom was the most significant environmental innovation in history.

Whilst there are plenty of 'low-tech' solutions to stop conception, there is now a preventative prophylactic in the works apropos for an EcoGeek. A remote control, implanted device will allow users to 'press pause' on their sperm (although it doesn't mention whether a 'rewind' function is in the works).

The device has been developed by Australian scientists and could herald a new dawn of even more convenient contraception for men, which has the potential to keep population growth under control more effectively.

A surgeon inserts a silicon chip into the vas deferens. A key fob sends out RF waves, just like the key to your car. The silicon chip converts the RF into acoustic waves, which in turn induce movement in the material, allowing it to expand and seal the tube. Sending another pulse from the key fob lets the material contract allowing sperm to pass.

However, to avoid 'cross talk' with say, your cordless phone, WiFi or bluetooth devices, ultra-high frequencies are used, combined with sophisticated coding, to make sure that no mistakes can occur.

All they need to do now is integrate a button to turn off the lights so you can save electricity.
