Is this the greatest piano solo?

In 1985 Gordon Sumner aka Sting took several huge risks. With The Police he’d ridden an enormous wave of success, with memorable hits such as Roxanne, Message In A Bottle and Every Breath You Take. Then in 1984 – at the top of their game, The Police broke up, and Sting set about converting his fame to a solo career.

That was risk enough, but he combined that with filming the experience of forming a new band and rehearsals for their premiere concert in Paris. As Sting says in the resulting movie Bring On The Night, most movies about pop bands are made towards the end of their careers when they’ve had years honing their craft as a combo. Filming a nascent band in the early stages of becoming comfortable with each other was truly a leap of faith.

Lindy Hop, Charleston and Shag Dance

If you don’t know the difference between Lindy Hop, Charleston and Shag Dance, well neither do I TBH. But I’m gradually learning a little since one of the jazz bands I play with – Chicos Swing Combo – has been doing gigs for 8-Count.

Their next swing dance event is on Saturday night (April 17th, 2021). Details here.

It’s a blast to play for these shows; I’ve never seen such enthusiasm to get on the dance floor. So much so that between the band’s two sets, they turn on a dance DJ so the Eight Count crowd can just keep on dancing and having a ball. Though the typical age group seems to be 20 to 40s, there are people of all ages and abilities. There’s usually a dance teaching segment or two as well, sometimes aimed at beginners and sometimes for advanced swing steps.

Episode 7 – Battery storage – Tesla Powerwall 2

2020 – Battery options modelling

In the middle of all that work on evacuated tubes, we learned that change was imminent in the SA Government Home Battery Scheme. To qualify for the maximum $6k subsidy, applications had to be lodged by 15th April.

Our modelling indicated that our 21kW PVs were generating enough power to usefully support up to about 55kWh of battery storage, corresponding to 4 x Tesla PowerWall 2 batteries. In cost-benefit terms, a sweet-spot would be with 2 batteries. In the depths of winter in July we’d still generate enough net power to fully charge the batteries for use overnight.

Episode 6 – More evacuated tube solar hot water boosters

Adventures with an environment-conscious inner-urban community

2020

This was the crisis year for so many people – bushfires, COVID, job losses – and it also happened to be the year of our most adventurous emissions-reduction planning, carrying out 2 major projects a few months apart.

Stage 2 solar hot water boosters

The evacuated tube solar hot water boosters we had installed in 2018 were performing well, so it was time to build the second stage. We’d completed the design work in 2019 and had commenced the Development Application (DA) process with the City of Adelaide in September 2019. DA is required by Council if solar collectors are not mounted flat on the roof. After 9 weeks of back and forth, providing additional drawings and details, we finally received Planning Consent in mid-November.

Episode 5 – Finalist – Carbon Neutral Adelaide Awards

Adventures with an environment-conscious inner-urban community

2016 to 2019 – Carbon Neutral Adelaide

Since 2016 we’d had regular contact with the Carbon Neutral Adelaide team, culminating in our carbon emission inventory for the 2017 year. I’d also attended the Carbon Neutral Adelaide Awards nights in 2017 and 2018.

I’d found the Awards nights to be highly motivating. To be in the room with such a mix of corporates, NGOs, SA Government and Adelaide City Council people, all focussed on working more efficiently and will less emissions was memorable and inspirational.

Episode 4 – Major PV upgrade

Adventures with an environment-conscious inner-urban community

2019

For years we’d been tossing around options for increasing our solar performance without losing our high feed-in tariff (56c/kWh) for the 4.8kW PVs that were installed when the Christie Walk community built the Sturt Apartments in 2006.

But by 2019 it became clear that preserving the high feed-in tariff was a false economy. We’d be better off financially and environmentally if we replaced the PVs and inverters with a high performance 21kW system.

Episode 3 – Evacuated tube solar hot water boosters

Adventures with an environment-conscious inner-urban community

May 2018

We started investigating the retrofit option for our hot water system: installing solar collectors as boosters to our existing heat pump hot water. One company stood out as a solid option: RunOnSun, based in the Northern Rivers region of NSW. Their website wouldn’t win a Webby Award for design, but the content is comprehensive and very educational. MD Andrew Butterworth has spent more than a decade applying Sydney University research on evacuated tube solar hot water and finessing it for efficiency and robust performance. The fixings supplied by RunOnSun are robust too; more than adequate to secure the system in cyclone conditions.

We decided to split the retrofit project into two stages. Stage 1 – 60 evacuated solar collector tubes – would be evaluated before moving onto Stage 2 – an additional 48 evacuated tubes.

Episode 2 – Doing a carbon inventory

Adventures with an environment-conscious inner-urban community

November 2017

I received an email inviting me to a meeting with the Carbon Neutral Adelaide team. They were scoping out a number of sites for selection as a possible “Carbon Neutral Showcase Site” and Christie Walk was on the list.

This was very exciting.

An important goal at Christie Walk is to act as a sustainability model, to demonstrate what’s possible, and to motivate others to take action. Close cooperation with Carbon Neutral Adelaide would enhance that outreach work.
