I invented a camera that has an exposure time of one hundred years and the camera works in the simplest possible terms, because anything more complicated is more likely to break down in one way or another. It's a pinhole camera that lets in very low light and instead of exposing film, which is going to spoil within a matter of days or weeks, I'm using ordinary black paper.

It isn't a matter of hope. It's a matter of - between the options of trying nothing and trying something, let's try something but let's also be very thoughtful about what that something is.

Take the self-driving car and the smartphone and put those together and think about how to manage a smart grid because suddenly you have all of this data coming from those two mechanisms that allow for a much higher level of allocating energy much more efficiently.

Let's not be optimistic in the irreversibly irresponsible way that tends to happen with the crazies of geo-engineering. But let's talk about what sorts of changes we can make.

I don't know whether what I do is art. But making things out in the world and having as many conversations as possible.

My work is very eclectic. I write books that range from writing fiction, writing fable where I am very directly trying to imagine alternate worlds, to writing about [Buckminster] Fuller who was the ultimate world man creating all sorts of alternate worlds and believing that they were imminent to my own work of - for instance, a project that I've been working on for some year and a half, two years now that continues to evolve has been what I call Deep Time Photography.

[Buckminster Fuller] started talking about it far enough afterwards, an audience that was far enough from when they - when the air flow and the Zephyr and these cars in the time period that were made by mainstream automakers. It was far enough in the future, far enough after that point that nobody really bothered to fact-check.
