Flyte Levitating LED Lightbulb Is Awesome


What do you get when you combine the power of electromagnetic induction, and uh, magnets? You get the Flyte LED Lightbulb, of course. Much like the wireless smartphone chargers you see today, this LED bulb is powered from a distance through the magic of electromagnetic induction. But the added flair in this product is that the entire bulb and housing levitate above their base, slowly rotating. The base is plugged into an outlet and some electromagnets keep the bulb in place, while powering the LED. 5V of power are sent through the air, which is enough to generate a modest 60 Lumens. At $249 it’s on the very pricey side, but think of the amazed looks on your guests’ faces and maybe you’ll think it’s worth it.

OhGizmo! Review – Powermat Wireless Charging System For The iPhone 4

Powermat Wireless Charging System For The iPhone 4 (Image property OhGizmo!)
By Andrew Liszewski

Back in July we reviewed a handful of Powermat accessories, including their Receiver Hard Case for the iPhone 3G & 3GS. While we liked the convenience of being able to just set the iPhone down and have it start charging, it came at the cost of a fairly bulky case plagued by an inductive coil on the back that stuck out like a sore thumb.

But half a year later not only do we have a new and improved iPhone, but also a new and improved Powermat case to go with it. And let’s just say ‘improved’ is an understatement. From our own testing we found that Powermat has addressed most of the issues with their case designed for the 3G & 3GS, and left us with a wireless charging solution for the iPhone 4 with minimal compromises. More after the jump.

OhGizmo! Review – Powermat Wireless Charging Solutions

As we inch closer to the promise of a wireless world, the holy grail of cutting the cords, wireless power, still eludes us. WiFi, Bluetooth and cellular technologies have replaced network and other cables, and while they’re not perfect, they continue to improve every year. But truly wireless power, like being able to walk into a room and have your devices start charging automatically, is still something you only hear about in laboratories and R&D facilities. So for the time being inductive charging systems, like those offered by Powermat, are the best ‘wireless’ power solutions that consumers can actually get their hands on.

The idea is pretty simple. An induction coil on a ‘base station’ plugged into the wall uses electricity to create an alternating electromagnetic field, while another induction coil on a device converts that same electromagnetic field back into electrical current which charges the battery. The technology only works across a very short distance, but it does away with the need for a direct electrical contact, meaning you don’t have to physically plug anything in, just place the devices near each other. While it’s not exactly the wireless power solution everyone dreams about, it’s still a far more convenient alternative to charging cables. The technology is still in its infancy though, at least in consumer-ready products like those from Powermat, and there’s still a few speed bumps that will have to be overcome before they become a must-have accessory in my opinion.

Haier HDTV Is Completely Wireless, May Or May Not Render You Sterile


By Evan Ackerman

This TV from Haier (I guess they’re an electronics company or something) doesn’t just feature wireless HD… It’s totally, completely wireless. Wireless power, folks. What does it take to transmit 3 gigs per second of 60hz 1080p plus 100 watts of electricity? A gigantic antenna is what, as you can see right in front of the distracting jerk with the ponytail who got in the background of my shot:


We talked to the Haier reps about just what exactly would happen if you got in between the antenna and the TV, and while they said that it was perfectly safe, I’m going to assume that that’s just PR-speak for, “it’ll definitely turn you into a super hero while giving you some form of cancer.” We have no information on when you’d find something like this in your house, but the wireless HD probably won’t be available before 2011, about the same time as non-chafing lead underpants.
