How would you like to charge your iPod... wirelessly?
That's right. That wasn't a typo. Wirelessly. The stuff of many myths and science fiction novels has actually come to fruition, but has it always been with us all along?
Serbian inventor Nikola Tesla was at the forefront of electricity and how it can work through wireless fields. His first experiments about broadcasting power wirelessly were done way back in 1890. He used work developed by Michael Faraday in 1831 to research the property known as electromagnetic induction. Basically that means that having one wire with flowing electricity near another wire with no flowing electricity causes the electrons in the dead wire to start to move.
It's now 2009. 119 years later and Tesla already has a car named after him, nevermind the whole wireless technology bit. We now have plenty of companies starting to come into the market offering wireless charging bases, and even planning mobile electronics to be wireless in the not so distant future.
Power enthusiast company PowerCast was one of the first companies out with the technology, offering a... wireless christmas tree. Well, not the most practical of applications for wireless power, but it's a start, and at least allowed people who love moving their christmas tree's the freedom to do so.
So how come 119 years later we're just starting to find applications for the technology? That's a question for the inventor/application scenario's. Some people hypothesize that big businesses destroy innovations that could be threatening. Some say that there was no need for innovation of wireless electronics before today's market. Whatever the reason, free-range innovation and adaptability to new solution is what keeps us strong, and our iPod's charged.
