RE: The future, reusable paper
This is a great example of the use of the TRIZ problem solving principle of "separation upon condition" where a system or product changes its behavior or properties in response to a change in force or condition... (Read the rest)

The future, reusable paper

At the Gartner Symposium/ITxpo in Las Vegas, Steve Hoover, vice president with Xerox Research Center Webster, shows off a technology being developed in the company's labs that enables people to reuse a piece of paper. The paper contains a photochromic compound that makes ink disappear when hit by direct heat.

Gavin Newsom: We are now looking at harnessing Mother Nature in a very subsistent and significant way.

Kara Tsuboi: San Francisco Mayor Gavin Newsom is referring to two renewable energy programs the city is exploring, Power Tap to the Power of the Ocean.

Mayor Newsom: This is not science fiction; this is not Discovery Channel.

Kara: The first is wave power.

Mayor Newsom: These wave energy platforms exist around the world, so this one truly isn't rocket science. It' just going to require subsidized costs to be invested upfront and demonstrate a capacity to do it again on scale where we can really take advantage of the entire coast.

Kara: Proposed off the city's Ocean Beach the feasibility of this project is currently under review.

Mayor Newsom: So I don't care what the study says, I just want the study to direct us in a better way.

Kara: Even if the reports are negative?

Mayor Newsom: It just gets us to think a little differently, so we can act a little differently. I want to use that information just to make us make a better bad decision, based upon what our critics believe, but a better decision based on what our supporters believe.

Kara: Pacific Gas and Electric Company have already backed a pilot program that could potentially provide two megawatts of electricity, enough to power 1,500 homes.

Mayor Newsom: The vision also really being, replacing all the polluting oil platforms off the coast of California with green wave generating energy platforms.

Kara: The second program under review is Tidal Power.

Mayor Newsom: Just unbelievable untapped energy that comes in, it's like a toilet bowl. Every single day it sort of flushes in, and flushes out.

Kara: Mayor Newsom is referring to a site 600 meters east of the Golden Gate Bridge that can one day house a tidal power device.

Woman: It's very similar to wind turbulence except it's underwater. Because water is so much denser than wind the devices don't have to be as large as the large scale wind devices. So world class tidal current is about four or five knots, and we've got about two to two and a half knots under the Golden Gate Bridge.

Kara: This limited size of tidal power and the overall expense of the device is why a newly released feasibility study does not recommend the city move forward with the Tidal Power Project just yet.

Woman: We're hoping that there would be more potential there.

Kara: Mayor Newsom however, is undeterred.

Mayor Newsom: That's because it's a brand new technology, it's never been done. It's never been scaled commercially in North America. So it's just like solar, until you bring it to scale these new technologies are always going to cost more.

Kara: By the year 2012, San Francisco has set some audacious rules for its renewable energy programs.

Women: Well, our peak power usage in San Francisco is about 950 megawatts. So we're looking at 50 megawatts of that, only, coming from renewables, and that's going to be a big target, a big goal for us to reach.

Mayor Newsom: If we believe in energy independence, and I do, as the paramount for a policy for this country. Rather than subsidizing failed wars overseas, billions may die, I'd rather see a subsidizing more enlightened policies for alternative sources of fuel and energy.
