Unlimited Range Electric Vehicles?  GREEN Power from tires! Nikola Tesla

Nikola Tesla created a device for wireless energy transfer using high frequency electromagnetic radio waves over 100 years ago. Ultimately, we will be using wireless transfer of energy to at least charge electric vehicles. Many researchers are proposing to power electric vehicles wirelessly giving us unlimited range. Often suggested is induction using the alternating current in one coil to induce electricity in another coil. This is the same technology that is used in transformers, like the power supply for your laptop battery. It is also used to wirelessly charge mobile devices and has been seen in wireless toothbrush chargers.

Masahiro Hanazawa at Toyota Central R&D Labs and Takashi Ohira at Toyohashi University of Technology speculate that the steel belts in tires can be used for the energy transfer and they are not using coils. Grid-supplied power is “converted into radio frequency (RF) by high-speed inverters implanted along tracks in the road. The RF voltage is applied to a balanced metal track embedded under the surface of the road. The EV picks up the RF voltage via electrical capacitance between the metal and a steel belt installed inside of the tires of the EV.”

Unlike the magnetic energy transfer of coils, RF energy uses a higher frequency electronic circuit. These can be tuned like a radio to a specific frequency. And like radio waves, they are easily transmitted. The electrical leakage is described as “small” and infrastructure would be less expensive than using a magnetic coil system. What is unique to their research is using the steel belts of a tire as a receiver. Tesla would be proud.

A little about us:

WhyGREENPower.org is on a quest to see how far we can push the limits of GREEN Power & technology on a residential home and we ask for your support.  We are a nonprofit & not trying to sell you anything.  We are simply trying to share what we learn about GREEN Power for all to leverage Help us get the word out?  At a minimum, if you wouldn’t mind “following”, forwarding & supporting WhyGREENPower.org on your favorite Social Network, that would be GREATLY appreciated!

What is this all about?:  WhyGREENPower.org shares GREEN alternative energy solutions like solar, wind and other technology to help towards independence from power bills & fuel costs… and even transportation costs.

Who?:  A group of industry GREEN experts have offered their assistance to show that GREEN Power is not onlygood for the earth, but your pocket book as well!

What?:  One of our first projects is to track the progress of one residential home for 12 months to see how far we can takeGREEN Power.  In the first month a savings of 41% was obtained on the first power bill. We will continue to track the progress and share what is learned along the way as we continue to make enhancements and leverage technology.  Did we mention the ROI including all incentives right now is less than 3 years.  Now it’s on to solve for the other 59%!  J

Are we selling anything?:  Simply. No.  Only advocating GREEN Power and sharing what we learn.

Up and coming GREEN!:  So you know about our quest to reduce the power bills.  What you might not know is this fall we will start a separate project to leverage the GREEN Power from the house to charge a electric vehicle (EV). Good bye  $4 dollars a gallon!  Stay tuned. Stay GREEN.

 Have an idea?:  We would love to hear from you.  Have an idea for the a blog post? suggestions@WhyGREENPower.org

Let’s share, learn, and promote GREEN Power!

Your friends at WhyGREENPower.org,

PS – Did you know?:  The federal Tax Code (HR-1424) is offering, through 2016, a 30% Tax Credit on batteries, panels, wiring, and installation costs associated with a GREEN Power purchase.

    fascinating. thank you. it is clear that all electric cars are no longer just an idea. lets support initiatives such as these to become 100 sustainable and focus our energy on cleaning and loving this planet instead of robbing it of all the good it has to offer. thanks to you guys for this great site and for your green efforts we look forward to reading more about your 100% sustainable home.
