24-hour solar on demand: an update on Solastor plans for Port Augusta

In June 2016 I reported on the launch of the Solastor 24-hour solar-on-demand project that was planned for Port Augusta in South Australia. At the time of the launch the plan was to have a pilot plant in operation by the end of the year. In November 2016 Solastor advised that they were likely to go ahead with the main project rather than doing the pilot first.

Today I checked in with Steve Hollis, CEO of Solastor, for an update on progress.

Brian:  Your Port Augusta plans outlined in your June 2016 launch were for 1,700 collector tower modules which were expected to generate 110MW in winter and 170MW in summer. Is that still the plan?

Steve:  The proposal is now to stage the project starting with a 100MW power station with 800 modules. This would do just under 50MW for 24 hours in winter and over 70MW in summer. More importantly, it will do 100MW for shorter times per day (peak hours) which is when the need is greatest.

This configuration could (would) be “cut and pasted” 5 times to give 500MW and completely replace the old to power station. Continue reading

Five paradoxes about the state of the media

We are living in a time full of threats – and unprecedented possibilities, especially when it comes to the state of the media. Let’s consider five paradoxes, in no particular order.

Is print dead or reviving?

Rumours of the death of print magazines and newspapers have been circulating for years – but many of us are still here. What’s more, we are seeing signs of a renaissance in independent, alternative print magazines and hyperlocal newspapers.

The internet, that great disrupting technology, has prompted print’s decline, cannibalizing the revenue of publishers. After all, why buy news in print when you get it all for free online? The proportion of readers actually prepared to pay for news online (nine per cent) cannot replace those who used to buy print.1

But the internet has also been amazing for media like ours. In the days before the worldwide web, we never imagined that two million people a year would be reading our content and getting our kind of journalism, rooted in social, economic, global and environmental justice. Continue reading

Snowy Hydro gets a boost, but ‘seawater hydro’ could help South Australia

The federal government has announced a A$2 billion plan to expand the iconic Snowy Hydro scheme. It will carry out a feasibility study into the idea of adding “pumped hydro” storage capacity, which it says could power up to 500,000 homes. The Conversation

Hydro is one of the oldest and most mature electricity generation technologies. And pumped hydro storage – in which water is pumped uphill for later use, rather than simply flowing downriver through a hydro power station – is the dominant form of energy storage globally.

But there are limitations to how much freshwater hydro can be accessed, so it’s worth looking at what alternate approaches are available. One promising prospect is to use seawater instead of rivers. This tactic could potentially help South Australia resolve its highly publicised energy problems. Continue reading

A new model for the future of independent media

It’s a huge day for our colleagues in the New Internationalist office in Oxford UK. That’s where the magazine’s editorial team is based and where New Internationalist books and the famous One World Calendar are produced.

Today they are launching their #factsandheart Community Share Offer. It’s a fascinating new model for the ownership of independent media, and a chance for supporters of the New Internationalist to become co-owners.
