It would be interesting to map the number of disaster movies released with the following article extract.  It points out that in the USA shelters and bunkers are undergoing a revival, and it interests me as it’s a possible weak signal of something happening around how people perceive risk.

Radius Engineering in Terrell, Texas, has built underground shelters for more than three decades, and business has never been better, says Walton McCarthy, company president.

The company sells fiberglass shelters that can accommodate 10 to 2,000 adults to live underground for one to five years with power, food, water and filtered air, McCarthy says.

The shelters range from $400,000 to a $41 million facility Radius built and installed underground that is suitable for 750 people, McCarthy says. He declined to disclose the client or location of the shelter.

“We’ve doubled sales every year for five years,” he says.Other shelter manufacturers include Hardened Structures of Colorado and Utah Shelter Systems, which also report increased sales.

In a previous post about crowdsourcing, I highlighted an important point from an HBS Working Knowledge Article:

For user innovation to be a force, the cost of creating a new design must be within the reach of a single user, whose reward is solely the improvement of his or her own experience.

The article referenced the work of Eric von Hippel and the ‘lead-user’ theory of innovation.  This basically states that small groups of people can start new industries, and for corporations to leverage this they need to work with lead users to uncover potential revenue streams.

As an example the article referenced the sport of rodeo kayaking.

It seems there is another example coming through popular culture – longboarding.  As an indicator/weak signal check this quote from an article on the sport in the NYT:

“People are always going to create their own stuff and that’s what’s happening here. These guys are creating skateboarding and reinventing skateboarding.”
