Why should you read “Macbeth”? – Brendan Pelsue | TED-Ed

Let’s Begin…

There’s a play so powerful that an old superstition says its name should never be uttered in a theater. A play that begins with witchcraft and ends with a bloody, severed head. A play filled with riddles, prophecies, nightmare visions, and lots of brutal murder. But is it really all that good? Brendan Pelsue explains why you should read (or revisit) “Macbeth.”


The best books on Climate Change Uncertainty – a Five Books interview

recommended by Kate Marvel

‘When we talk about climate change, we sometimes assume people will be swayed by one more graph, one more coherent argument. But that’s not how people work. More facts don’t change minds, and deeply held views don’t always dictate behaviour.’ How, then, to grapple with a future that ‘might be weirder than we realise’? Kate Marvel, Associate Research Scientist at Columbia University and NASA, recommends an essential reading list for those ready to confront climate change and the uncertainties it brings

This Incredible Short Film Looks at the Frightening Potential of Virtual Reality

In this sci-fi short film, we get a dark look at the possible implications of virtual reality, and what happens when the lines between reality and fiction begin to blur.


New Finkel report finds no need to panic about energy storage : RenewEconomy

A new report into energy storage commissioned by chief scientist Alan Finkel highlights the enormous opportunities for storage in Australia, but underlines how little is actually needed over the short to medium term, even at relatively high levels of wind and solar.

The report, The role of Energy Storage in Australia’s Future Energy Supply Mix, funded by Finkel’s office and the Australian Council of Learned Academies (ACOLA), says the required investment in energy security and reliability over the next five-10 years will be minimal (see graph above), even if wind and solar deployment moves far beyond levels contemplated by the Energy Security Board.

The contrast with the ESB modelling – and the attempts by Coalition parties at state and federal level to dismiss high levels of renewable energy as “reckless” – could not be more pronounced.

While the ESB, in arguing for a National Energy Guarantee, speaks of the system threats and urgency to act with a level of “variable” renewables accounting for between 18 and 24 per cent of total generation, this new report says surprisingly little storage may be needed with 35 per cent to 50 per cent wind and solar.


New Discovery Raises Hope for Human Colonization of the Moon

Moon Cave Colonization

In October 2017, Japan’s Selenological and Engineering Explorer probe discovered a massive underground cave on the Moon. The space, which is 100 meters (328 feet) wide and 50 kilometers (31 miles) long, is being touted as a potential location for a lunar station. In fact, some experts are asserting that the best way to live on the Moon is in caves just like the one recently discovered.

Radio waves were used to investigate the cave, after an opening measuring 50 meters by 50 meters (164 feet) was found by the probe. It’s thought to be structurally sound, and could contain deposits of ice and water inside rocks that might be used to produce fuel.


Renewables option $1.3 billion cheaper than keeping Liddell open : RenewEconomy

The Turnbull government’s plan to keep the New South Wales Liddell coal-fired power plant open beyond its use by date would cost upwards of $1.3 billion more than replacing it with a mix of renewables and energy management systems, a new report has found.

The research, conducted by the Institute of Sustainable Futures and commissioned by the Australian Conservation Foundation, is just the latest to illustrate the economic folly of keeping Australia’s oldest coal plant in the national electricity mix, in an age when renewable energy costs and carbon budgets are dwindling.


The report finds that a combination of wind power, demand management and energy efficiency would cost $2.2 billion over five years, compared to a cost of $3.6 billion to keep Liddell open for five years beyond its retirement age.

The AGL Energy owned Liddell – which AGL itself has repeatedly described as unreliable and costly– is slated for closure in 2022, at which time it will have reached the grand old age of 50.
