Trying a Dyson Sphere on for Size

Futurist and ethicist George Dvorsky wrote this article about how to build a Dyson Sphere. He makes nanotechnology robots building solar panels in the solar system by totally mining Mercury (and then Venus) for materials sound simple. I like the comment on the article by the guy who asks if mining Mercury - every last bit of it - is ethical. This reminds me to try and find a post on nanomedicine and ehealth - another subject to be considered by futurists and ethicists.

The wireless transmission of electricity from the solar arrays is a vision Nicholas Tesla would be proud of. How better to get the electricity to the Nissan Leafs we will all be driving, without waiting to plug in and recharge.
