Ardica Technologies

Ardica Technologies specializes in lightweight, environmentally friendly fuel cells. They are concentrating on developing consumer and commercial wearable heat and power as well as portable soldier power. Several companies are beginning to integrate the technology in to their garments. The heart of the matter is Ardica’s Moshi Power System, which relies on new Lithium Ion battery technology coupled with a micro controller and a wall charger. A technology connector kit is also available which comes with a backpack cable and a three-in-one connector for both running and charging various consumer electronics.

Not only will the system power an on board heater for either eight and-a-half hours on low heat or three hours on high (peak 100 deg), it will also charge ancillary gear such as up to 11 full charges on a cellphone or a whopping 20 on an iPod. Considering the possibilities, the added cost of $35 to $50 per garment is reasonable. However, weight is still an issue. Each Lithium Ion battery weighs half a pound with a total system weight of one pound.

Velcro Alternative?

Tuesday, October 28th, 2008

One of the winners of the last year’s Pop Sci Inventor awards was Leonard Duffy’s “Slidingly Engaging Fastener”. Although Duffy has succeeded in developing a great alternative for Velcro, his original intent was to develop an improvement to the zipper after a bag he was carrying wouldn’t close. The fastener works through a matrix of injection molded “islands” resembling clubs from a deck of cards that lock into one another. Duffy previously won a NASA inventor’s award for a wrap around cast using the fastener that he developed for his sister-in-law when she injured her wrist.

The inventor claims it supports eight times the weight of Velcro, doesn’t lose it’s stickiness and best of all is silent. Unfortunately, no one has picked it up for development yet but it looks like it has potential in the tactical nylon industry.
