There's another aspect, which is the shine effect. So , the Anish Kapoor patented black, the least reflective material on earth, had a shine effect of zero, and perfect white, of one... [A]n ocean or a parking lot has almost no shine effect so it absorbs a lot of heat. So the more open ocean... the more parking lots, the more heat is absorbed, whereas fresh snow has a... good shine effect... [T]o give you an idea of how impactful this is, if earth was all ocean we would have an average temperature of 27°C. Today it's 15°C... If 1/3 of the planet was glacial, it would be frozen. So 1% of change in the shine effect of earth is the equivalent of doubling the amount of <chem>CO2</chem> in the atmosphere. So it's also an important factor that... now works against us.

[W]hat was mesmerizing... was this... marvel of modern engineering... was going to be the cleanest waste-to-energy power plant in the world. No toxins coming out of the chimney. So we thought maybe a mountain of trash could become an actual mountain. Our nearest ski slope... is 6 hours away in Isaberg... Sweden... We could put 2/3 of Isaberg's main slope on the roof of the power plant, and so we did. ...The kind of cliff face of the mountain is made out of these gigantic folded raw aluminum bricks that are... planters. ...Raw aluminum so they... reflect the surroundings, so... the building changes color over the course of the day. ...The entire power plant is ...daylit. 50% of the facade is transparent. ...This spring it's going to open the tallest in the world, 300 feet. ...[T]he roof is maybe the most exciting facade. ...[T]he skiing is ...free. It's a public park. If you want to use the lift system, you have to buy a lift pass. It's... designed to... help spread vegetation to the surrounding... post-industrial area. You have hiking paths, different... activity zones. You have... vegetation that changes over the... season. There's more than 400 different trees. ...It's purely indigenous species. If Denmark had mountains this is probably what they would look like. ...[T]he entire roof park has been made for a budget of... $13 million dollars... absurdly inexpensive so everything has... been done with... the least... maintenance and... acquisition cost. ...Maybe the most important material, because Denmark doesn't have enough snow so... we found this Italian company that makes this... mat that has the same friction as a groomed slope. The only problem was that it was... ugly. Also because of the and contraction it had to be split in... 7x7 foot squares. So we sat down... with the company and... managed to develop a... new product... by joining every two circles [holes in the material] in two... directions... This... simple geometric invention... now the standard product of the company, meant that we could have a continuous surface on the... roof... We color-coded it so that the brighter the slope... the less likely... to crash... [E]ventually the grass grows through... [T]he grass... holds the mat to the roof, so eventually it's going to be like skiing on an alpine meadow. ...What is amazing ...it ...shows this ...world-changing power of architecture ...[M]y son is ...never going to remember that there was a time when you couldn't ski on the power plant in Copenhagen ...[F]or him and his entire generation, that's going to be their normal ...the starting point from where they start having crazy ideas about their future. ...A landmark for this ...idea of hedonistic sustainability, that a sustainable city can also be, not just better for the environment, but better for the people living there.

[Y]ou have different kinds of es, 4 of them affected by human activity, and of the 4... carbon dioxide and methane... nirous oxide loop and... F-gases... [I]f you have 610 gigatons of carbon in our vegetation, you have a million times more in the sediments, and that's... what we're releasing by burning fossil fuels. So you have two carbon dioxide loops, one takes millions of years as volcanic activity, but then becomes sequestered in rocks and sand and it's then... sedimented on the ocean floors and it's pushed back through tectonic movement into magma... [T]hen you have a more annual loop, which is... living beings absorbing <chem>CO2</chem> and then... releasing it through respiration, decomposition and... human emissions...

So what are our energy sources? We have 4... the sun, that provides photovoltaics, solar heating, fossil fuels, wind power is all... solar energy; Earth... thermal energy..; the moon, tidal turbine energy... because of gravity; and nuclear energy... So... all the different forms of energy are related... Gravity creates pressure, nuclear activity through fusion provides sunlight. Through sunlight is translating into chemical energy that can... be burned to provide heat, that with an engine can be translated into kinetic movement, that can then be turned into electricity... [O]ver the years we've been... mastering more... of these translations... [A]ny kind of energy source is translation... so a water mill or hydropower is gravity turned into kinetic movement and from there into electricity. Nuclear fission is nucler energy translated into heat and from there into mechanical and electrical. Batteries: from chemical to electrical... [I]f you look at the energy storage vs. batteries... It's not very efficient. 1/2 ton of batteries has the same stored energy as 5 kilos or 10 lbs. of hydrogen.

[T]his... relationship between the pragmatic and the utopian, or... the utilitarian and the . One such example... This is where the Granville bridge touches downtown Vancouver. We got invited to look at turning it into a mostly residential and also educational development. So we just started mapping the constraints. There are setbacks from the streets... from the bridges. The city has a rule that you cannot build residences closer than 30 meters, or a hundred feet to the traffic on the bridge. There's a park where we're not supposed to cast any shadows, and finally we were left with this tiny triangular footprint, almost too small to build. So... we started thinking... If the purpose of the 100 ft setback is a minimum distance, once we get a hundred feet up in the air we can grow the building back, so... the triangular footprint... turns into a rectangle. ...[W]hen you drive over Granville bridge it's... as if someone is pulling a curtain aside, welcoming you to Vancouver.
