Is the name "Tesla" anathema to mainstream science? This goes for both the scientists and the reporters who write their stories. You would think none of them has ever heard of Nikola Tesla (save the NYT article). Why, if you read the above articles about wireless electricity you would walk away thinking this was a radical new concept! It's not.

Nikola Tesla imagined, developed and repeatedly demonstrated wireless technology one hundred years ago! In case you don't know who Nikola Tesla is... reach over and turn the light off... then turn it back on... now think of where that power came from. It came from the mind of Nikola Tesla. He invented alternating current. He designed and built the first AC power-generating station at Niagara Falls. He invented the radio. He discovered VLF waves. He... well, he did a lot of other things for which people today still refuse to give him credit (as evidenced by the absence of his name in the above articles).

So what is wireless energy? It is the transmission of electrical power without the use of wires... and it's very old technology that has been waiting for a century to be put to practical use. It involves resonance. This is best described by thinking of two similar instruments and how one will resonate when the other is played. The same is true with electricity. Take two identical copper coils, one transmitting and the other attached to, say, a light bulb. Place them a few feet apart. Activate the transmitter attached to the one coil and the bulb attached to the other coil will light up. The waves produced by the one coil cause the second coil to resonate with the same energy... thus producing electricity.

The first practical use I saw was a "charging pad" for cell phones and PDAs. While all wireless charging is not resonant it still is one method being used.

Practical Use?

I could go on... both on this technology and on the man who invented it a century ago. You can read all about both above. What I do want is to tell you how this can be used.

• First consider (go read) my previous post on supercapacitors.
  
• Now consider wireless power transmission stations along highways... remember that it takes seconds to charge a supercapacitor.
  
• What do you have? You have a technology that eliminates the need to stop and fill up (recharge) your car. You just keep driving!
  

Keep your eyes on this technology. Especially resonant tech as it shows the most promise for transmitting over distance... and that's where the real practicality is.

The Supercapacitors Are Coming!

One technology quietly making its way back into the limelight despite the lack of press is the capacitor. Capacitors have been around for over 250 years and have changed little since their invention. However today, with new technologies, capacitors are about to make a bound into the forefront.

I'm seeing these new capacitors grouped into two categories... supercapacitors and ultracapacitors. Now some of you are going to say, "These are the same thing!" and that's exactly what wikipedia says. But I don't think I agree.

Ultracapacitors are basically the same old capacitor technology but with more layers to create more storage capacity. Ultracapacitors are already making their way into everyday use. Zenn Cars is close to releasing its first ultracapacitor cars. These capacitors will pack up to ten times as much charge as conventional car batteries.

Supercapacitors seem to be different. A group at MIT are perfecting supercapacitors. They use carbon nanotubes to create the storage capacity. If claims are true these supercapacitors will provide even more power than the aforementioned ultracapacitors.


See if you can imagine this capacitor in your car

• All the power of a battery.
• A full charge in minutes or less... no different filling up my gas tank except I plug it into an outlet to charge.
• Will not lose its capacity over time like a battery.
• No harmful chemicals to dispose of or gases to blow up... just carbon.

That sounds great doesn't it? Let's hope the big motor companies don't find a way to delay the inevitable. The only drawback is that so much has been invested in current technologies it will be awhile before these capacitors hit their stride.

Hydrogen from seawater is a good idea!!

Of late I have been seeing greater numbers of articles with newer ways to extract hydrogen for use as a fuel. Many of these are very promising. For instance, Australia has an idea that it can provide 100% of its country's energy needs using hydrogen extracted from water by means of solar energy within the next ten years.

Next there's John Kanzius, who has found a way to use radio waves to extract hydrogen from seawater. He makes no claims as to the payback but simply that he has found a simple way to extract the hydrogen from seawater... leaving oxygen and salt as a byproduct.

I won't go into detail on these technologies as you can easily research them on Google. What I do want to discuss is the apparent lack of foresight and outside-the-box thinking by Internet posters. One poster said "Hydrogen makes no sense as a fuel EXACTLY because it takes more energy for us to produce it RIGHT NOW, than it gives us back RIGHT NOW."

Let me make this point. My body is one of the most efficient mechanisms (if not the most) for storing and using energy known. However, it is not 100% efficient... meaning it is NOT a perpetual motion machine. But you don't see me giving up on my body do you? uh... hardly. I take advantage of energy stored in the food I eat to keep me going. That's what we're talking about here.

My point? Just because something is not a perpetual motion/energy device in no way means it is unusable. 90% of the posts poo pooing the hydrogen-from-seawater device argue that it takes more energy to create the hydrogen than you get from the hydrogen. So what??? Does it not take more energy to charge any battery than you get from that battery? Of course it does. The benefit is that you have stored energy.

So, all of those who can't get past that mental block need to just go away and let the rest of us solve the problems.

How To Mass Produce Hydrogen TODAY

• Find an unused offshore oil platform - offshore but close to shore
• Deploy a number of existing technologies to produce electricity (wave energy, tidal energy, solar energy).
• Use the electricity to (1) power the radio wave emitter and (2) Pipe the hydrogen to the shore to be stored.

I know... you're saying, "So it still takes more energy to extract the hydrogen than the hydrogen itself provides!" aren't you? You are absolutely right. However, if that's what you're thinking you've missed the fuel-cell-powered bus altogether!!

Now, instead of having only the electricity generated by the various technologies, you have hydrogen to use in fuel cells for whatever you want and you can keep it indefinitely until you're ready to use it.

So, the next time you techno-nerds want to show how smart you are... think twice. It's not about "perpetual motion" and it's not about "perpetual energy". It's about "free Energy"! And there is more than enough on this planet to meet our needs for much longer than we (humans) will be here.
