Here are this week’s seven cool gadgets. Did you see last week’s edition?

Terrafugia Transition

I wrote about the Terrafugia vehicle back in March of 2006, three years ago. On March 5th of this year, a couple of weeks ago, their first working prototype, the Terrafugia Transition, made a successful runway-only flight. I’m really glad to see they managed to get their design built and working!

The Transition has foldable wings that extend and lock into place when it’s time to fly. It changes from a car into an airplane in less than 30 seconds. It has a top speed of 65 mph on the ground and 115 mph in the air. Its approximate fuel economy is 30 mpg, and it can fly about 450 miles on a full tank. Retail price is $194,000.

KOZO Lamps by Design2009

The Jenga Pistol

It’s a coil-action pistol that can be used to knock out Jenga blocks. Watch the video and see, my description is lamer than what this gadget does.

SwitchEasy ThumbTacks

They look like thumbtacks, but they’re microphones for your iPod. So cool! At only $13, I’d grab a couple in a heartbeat, except they won’t work with my 1st generation iPod Touch; they only work with the iPod Nano 4G and iPod Touch 2G.

Collapsible Crutch

This may be one gadget I’d rather not use unless it was absolutely necessary, but let me tell you, if it were necessary, I’d rather be stuck with these. I was on crutches almost 10 years ago because of a knee operation, and I found it annoyingly difficult to get them in and out of the car. These collapsible crutches expand and contract very easily, which makes that task a snap.

D3O

This wonder gel is soft at first touch, but it turns into a solid upon hard impact. It’s already being used in sportswear, and now the British Army has signed a contract with Blue Divine Ltd, the maker of the gel, so it can be used in the helmets of British soldiers. Very cool!

Iglooplay Mod Rocker

Someone tell me why this cool rocker is only made for kids? It’s so nice I’d get one myself. It’s made by ModernNursery of molded plywood, and can take up to 450 lbs of weight.
