I started Venus Labs http://venuslabs.org/ to research and promote exactly this idea! Join us and we can live in stratospheric penthouses on Venus, rather than basement tunnels on Mars...

A lot of science fiction postulates worlds full of designed creatures - Oryx and Crake, The Windup Girl, etc. Your efforts to revive extinct species could be seen as a stepping stone to that kind of technology. Are you intrigued by the possibilities? What kind of creature would you design?

Adafruit has been doing a lot of interesting stuff around wearable electronics recently, having hired Becky Stern. Do you have a vision for where you want to go with that stuff, how much of your own time is spent on wearables now?

I recently attended the Montreal Mini Maker Faire, had a total blast, you can read about it on my blog: http://www.digitalcrusader.ca/2012/08/montreal-mini-maker-faire.html

Metrix Createspace is just one example of a hackerspace. There are lots more all across the world. To see if there is one in your area, check the hackerspaces.org list. I've been a member at both noisebridge (in San Francisco) and hacklab.to (in Toronto), and it's been a wonderful experience.

I know that you did a lot of travel when you were younger (e.g. backpacking in Asia for years). How important was that for your status as a "Renaissance man"? Would you still recommended extensive travel to young people, or has globalization changed the opportunities?

Some friends and I are the creator of the North Paw compass anklet. You can check out our website at sensebridge, or read all of our hack notes on the noisebridge wiki: compass vibro anket. You can purchase North Paw kits from us for $95, and then you don't have to take Quinn's word for what it's like to wear one :-)

"Name an industry that can produce 1 million new, high-paying jobs over the next three years", challenges BusinessWeek. The obvious answer is Greentech. We need to scale wind and solar power production rapidly, for a whole host of reasons. Currently installed base took decades, and is still only 1% of the electric grid, so clearly there is lots of room to expand... and that's not even counting such opportunities as electric cars.

There is a group of people meeting on Sundays at Noisebridge in San Francisco, to work on devices like this compass belt, check us out here: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.noisebridge.net%2Fwiki%2FCyborg_Group
