Science with a Smile:) Could Rhubarb Revolutionize Renewable Energy ?

Rhubard

Flow batteries are rechargeable devices based on specific chemicals in liquids separated by a membrane.  They hold the key to cheap energy storage, especially if their dependence on expensive metals such as platinum and vanadium is reduced. Enter organic compounds called quinones.  Quinones are central to electron transport in photosynthesis (plastoquinone, phylloquinone), and aerobic respiration (ubiquinone). A discovery by Harvard biochemists suggests that quinones similar to those found in rhubarb may unlock the development of cheap flow batteries.

Solar Power Craze on Wall St. Propels Start-Up

Elon MuskBig changes are beginning to stir in solar energy. Heavy hitters such as Elon Musk (founder of SpaceX, Tesla Motors and PayPal) continue to see opportunities to transform the world through business excellence.  And those insights are catching on on Wall Street.  SolarCity is not simply a way to sell solar systems, it is a way to sell the energy itself, making “SolarCity almost like a newfangled utility”. Diane Cardwell and Julie Creswelljan wrote more on this innovation and the appeal it is generating in the New York Times last week. Continue reading “Solar Power Craze on Wall St. Propels Start-Up”

Want to know more about global change and coastal marine ecosystems?

The University of Queensland has opened a free on-line course (1-2 year University level – http://bit.ly/JEnRkV ) on Tropical Coastal Ecosystems and Global Change as part of the edX partnership with Harvard and MIT. This exciting course will introduce the major tropical coastal ecosystems (principally coral reefs, mangroves, sea grass meadows) and will explore the problems and solutions … Continue reading Want to know more about global change and coastal marine ecosystems?

Another record year for Australia

Yet another record passes.  Not only has Australia signalled the go-ahead for the world’s largest coal ports (Abbot Point), it will finish the year with 2013 being its hottest year ever.  Peter Hannam from the SMH puts it all together for us!

Happy New Year!

SMH, ENVIRONMENT EDITOR

2013 will go down as the year that registered Australia’s hottest day, month, season, 12-month period – and, by December 31, the hottest calendar year. Weather geeks have watched records tumble. These tallies include obscure ones, such as the latest autumn day above 45C (Western Australia’s Onslow Airport at 45.6C on March 21), the hottest winter’s day nationally (29.92C , August 31), and even Wednesday this week, with the hottest-ever 9am reading (44.6C, at Eyre weather station near the WA-South Australian border).

“I Got it Wrong on Climate Change—it’s Far, Far Worse”

By , SlatePosted Sunday, Jan. 27, 2013, at 11:11 AM ET

Nicholas Stern, the author of a 2006 report commissioned by the British government on climate change that has been used as a reference ever since, says he now realizes he “underestimated the risks” of rising temperatures. In an interview with the Guardian, Stern, who is one of the world’s leading environmental economists, says that had he known then what he knows now, he would have been “a bit more blunt” about the risks that climate change poses to the economy.

Climate Change Given Prominence in Obama’s Address

By  and , New York Times, Jan 21 2012

WASHINGTON — President Obama made addressing climate change the most prominent policy vow of his second Inaugural Address on Monday, setting in motion what Democrats say will be a deliberately paced but aggressive campaign built around the use of his executive powers to sidestep Congressional opposition.

“We will respond to the threat of climate change, knowing that failure to do so would betray our children and future generations,” Mr. Obama said, at the start of eight full sentences on the subject, more than he devoted to any other specific area. “Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.” Continue reading “Climate Change Given Prominence in Obama’s Address”
