Wireless Electricity and in future wirelessly charging your cellphone is that possible?

Yes the ad shows us a conceptual video about a family that is charging their electronic devices wirelessly. As most of you would have guessed by now the company sanctified by MDB Capital is Energous (WATT) eventually that same video could be found on Energous website too. Now that we are pretty sure the stock Nick Hodge is hyping in this teaser ad is WATT. Let’s look at the technology and its financial repercussions on WATT.

Wireless charging can easily be misunderstood for inductive charging. Inductive charging by the way is already working technology it uses an electromagnetic field to transfer energy between two objects. Electric current is typically transferred through an inductive coupling to a device, which can use that energy to charge batteries. It’s one of the best disruptive technologies available in the mobile world today as most device manufacturers have already adapted this technology.

What the heck is Energous doing with wireless charging?
Well, I think I have to scroll for more hints from the Energous website. Here’s what they have for us.

Works like Wi-Fi
A WattUp™ transmitter, or Power Router, sends energy via a radio frequency (RF) signal to your WattUp-enabled electronic devices when requested. A WattUp receiver in each device converts that signal into battery power.
The entire system is software controlled, so it’s intelligent and customizable to your needs and environment. And, because it’s designed to work invisibly in the background, WattUp makes low battery anxiety a thing of the past.

It looks fascinating what ensues is a little different proposition from Energous (WATT) as they seem to be doing something different from others. In fact Energous is trying to develop unified standards for wireless charging to take care of compatibility issues and they are really distinct in a (still in the test bed) category of wirelessly charging through (RF) signals. I am not sure if they refer Wi-Fi just to call the technology or of it’s exactly like a Wi-Fi connection between the charger and the device that gets the power. I am clueless really.

What it boils down to is this while everyone loves to own a product like this. I presume it has to be built into every device that uses it. It perhaps has to have a power receiver chip in it that works with Energous power network.  So that’s a big ecosystem. I think without associations from big device manufacturers such as Samsung or Apple it isn’t going to see the light of the day.  In fact it’s all about getting the technology to general masses, getting finances for the project, keeping investors involved, and most importantly in a proper timeline.

So much of that is in a very much obfuscated environment it seems the stock is already sold on the CES presentation and the news last month. There’s no judicious way to value the shares of the company, other than the cash reserves they have to sustain the current spending on R&D from the recent IPO, as most of the time it’s the press releases that drive the stock price, it turns out very risky to naïve shareholders when either the technology or the associations with the prospective partners go wrong.

I don’t mean that they aren’t going to get any partnerships in place, hence setting a new standard for wirelessly charging your devices as they seem to be in a very different niche, as others are using inductive charging mats. And this charging method is still a prototype that obviously works if their presentation video is to be relied upon.

If you have any of your own musings on Energous (WATT) do share them with us through the comment box below.

Disclosure: I don’t have any positions in any stocks mentioned herein, and no plans to initiate any in the near future.

    There may be problems with this concept. Note below:

    RF (electromagnetic) energy diminishes as 1/r^2 where r is the distance between the transmitter and the receiver. The transmitter transmits the charging energy to the device that requires charging.

    Thus, if you need 1 watt to charge your device when it is one foot from the charging transmitters then you will need to transmit 100 watts to charge the same device when the device is 10 feet from the transmitter.

    If such large amounts (in excess of10 watts) are transmitted continuously then:
    (1) the FCC may have to approve or license the transmitter,
    (2) human health/biological effects should be evaluated when continually exposed
    to the RF energy field
    (3) the system is highly inefficient when a large amounts of energy is transmitted
    and very little reaches its target, the battery to be charged.

      That is exactly why Apple and Samsung haven’t adopted the technology and there are many other repercussions to be looked at. Yet it’s a long way to go before the technology is adapted by the mainstream players.
