The Greening of Architecture
Nader Tehrani: Well you’re asking somebody who is a green architect as a citizen, but I’m not an expert of green architecture. I’m also one of the people that thinking that most architects are using the banner of green architecture as a kind of soup de jour. I think it is a serious issue. I think that we need to think about questions of policy, questions of production in a way that is sustainable, but not everything has direct architectural consequences and one needs to remember that we are not talking about formal determinism here. We are not talking about a direct consequentiality about a green principle and the actual form of a piece of architecture. Imagine if you will you make a great piece of green building if you like, a great piece of architecture that is also a green building you know on Route 128. What is the consequence of that building when the entire planning principles of the United States in a way cultivate an attitude about sprawl? So the question of sustainability and the green movement needs to deal with the potentials of its impact on planning, urban design and architecture as a larger political effort, the architectural consequences of which have been around for centuries. Very basic principles of a building’s orientation to the sun, the way it collects heat, the way it stores heat, the way it expels heat at night, these are well documented techniques that go back centuries and centuries. I think there are many ways of engaging the green movement, part of them through new technologies and part of them through… actually an elimination of the very technologies that we so rely on today. The building that we are in right now, the room that we’re in has no windows and requires a mechanical system to make it breathe. Most buildings probably don’t need that and it depends on how we design them, but that is not an excuse not to research technologies that would advance the way that buildings work in new ways and new forms, but the linking, the direct link of determinism between form and function, between form and performance, between form and the greening movement is a myth that we also need to overcome.
Question: Where are people working to create a more sustainable dynamic?
Nader Tehrani: I mean I think the mere decision to invest in our inner cities is one of those efforts. The idea that through more density, through less public transport… Excuse me, through less driving and more public transport, through ways of congesting if you like, our social, personal, institutional and daily lives that achieves that. We don’t need to cultivate that kind of thing in an ever expanding domain you know in the suburbs, so sure. I think that that is one way that we are already doing it, but that is not enough.
"Green" architecture is a kind of "soup du jour" at many firms, but the push to create sustainable buildings is an important movement.

Scientists have found evidence of hot springs near sites where ancient hominids settled, long before the control of fire.
Finances can be a stressor, regardless of tax bracket. Here are tips for making better money decisions.
- Whether you have a lot of money or a lot of debt, it matters how you handle your personal finances. A crucial step when it comes to saving is to reassess your relationship with money and to learn to adopt a broader, more logical point of view.
- In this video, social innovator and activist Vicki Robin, psychologist Daniel Kahneman, Harvard Business School professor Michael Norton, and author Bruce Feiler offer advice on achieving financial independence, learning to control your emotions, spending smarter, and teaching children about money.
- It all starts with education and understanding. The more you know about how money works, the better you will be at avoiding mistakes and the easier it will be to take control of your financial circumstances.
Astronomers spot an object heading into Earth orbit.

Identifying 2020 SO<p>The first clue 2020 SO isn't your ordinary asteroid is its exceptionally low velocity. It's traveling much more slowly that a typical asteroid — their <a href="https://www.lpi.usra.edu/exploration/training/illustrations/craterMechanics/" target="_blank">average rate of travel</a> <a href="https://www.lpi.usra.edu/exploration/training/illustrations/craterMechanics/" target="_blank" rel="noopener noreferrer"></a>is 18 kilometers (58,000 feet) per second. Even <a href="https://en.wikipedia.org/wiki/Moon_rock" target="_blank">moon rocks</a> sent careening into Earth orbit by impacts on the lunar surface outpace pokey 2020 SO.</p><p>For another thing, 2020 SO has an orbital path very similar to Earth's, lasting about one Earth year. It's also just slightly less circular than our own orbit, from which it's barely tilted off-axis.</p><p>So, what is it? <a href="https://cneos.jpl.nasa.gov/ca/" target="_blank">NASA estimates</a> that the object has dimensions very reminiscent of a discarded Centaur rocket stage from the <a href="https://en.wikipedia.org/wiki/Surveyor_2" target="_blank" rel="noopener noreferrer">Surveyor 2 mission</a> that landed an unmanned craft on the moon. Back in the day, rocket stages were jettisoned as craft were aimed toward their desired position. This stuff, if released high enough, remains in space. It appears that this Centaur rocket, launched in September 1966, is now making its way back homeward, at least for a little bit.</p><p>When 2020 SO arrives at its closest point in December, the rocket is expected to be about 50,000 kilometers from Earth. Its next closest approach is much further: 220,000 kilometers, in February 2010.</p><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQzMDk3NC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyODg1MTQ1MX0.HGknDwqp0GmeuczKY_AS7vrPG7KMFUc_XO95tNoI2xo/img.jpg?width=980" id="e5cda" class="rm-shortcode" data-rm-shortcode-id="85eb1f790d8c3ee5b261f7ba13eaa5e1" data-rm-shortcode-name="rebelmouse-image" alt="Centaur rocket stage" />

What we may be able to learn<p>Earthly space programs being as young as they are, scientists would love to know what's happened to our rocket during a half century in space.</p><p>While 2020 SO won't get close enough to drop into our atmosphere, its slow progress has scientists hopeful that they'll still get some kind of a decent look at it.</p><p>Spectroscopy may be able to reveal what the rocket's surface is like now — has any of its paint survived, for example? Of course, being out in space, it's likely to have been hit by lots of dust and micrometeorites, so the current state of its surfaces is also of interest. Experts are curious to know how reflective the rocket is at this point, valuable information that can help planners of future long-term missions anticipate how well a craft out in space for extended periods will remain able to reflect sunlight.</p>
The electric car manufacturer says updates to its battery design and manufacturing process will help lower production costs.
- The high cost of batteries is the main reason why electric vehicles cost more than gas-powered cars.
- At the company's 'Battery Day' event on Tuesday, Tesla announced a new battery design that will give its cars more power and a longer range.
- The success of Tesla's plan depends on its ability to scale up production.

Tesla<p>It's unclear when Tesla will stop using cobalt, or when it will stop sourcing its batteries from Panasonic. But Tesla claims that its new battery design and manufacturing changes will allow it to cut the cost per kilowatt-hour in half. If Tesla can successfully scale up production, the company could hit its goal of $100 per kilowatt-hour sooner than expected.</p><p>Hitting that mark could usher in the electric-car revolution, considering $100 per kilowatt-hour is <a href="https://www.greentechmedia.com/articles/read/How-Soon-Can-Tesla-Get-Battery-Cell-Cost-Below-100-per-Kilowatt-Hour" target="_blank" rel="noopener noreferrer">generally regarded as the threshold</a> the industry needs to reach in order to make electric vehicles cost competitive with gas-powered cars. </p><p>A $25,000 electric car would also be Tesla's cheapest offering by far. The company had previously promised a $35,000 car, but only offered one at that price for a limited time. Tesla's website says its Model 3, its cheapest car, starts at about <a href="https://www.industryweek.com/leadership/article/22027923/tesla-declines-as-model-3-price-cut-renews-demand-concerns" target="_blank">$39,000.</a></p>

Tesla<p>To be sure, Musk is known for promising big on his projects, but not always following through on the promised timetable. But despite having an "insanely hard" 2020, as Musk said, Tesla's had a good past couple years.<br></p><p style="margin-left: 20px;">"In 2019, we had 50% growth," Musk said at the event. "And I think we'll do really pretty well in 2020, probably somewhere between 30 to 40 percent growth, despite a lot of very difficult circumstances."</p>
