I liked this perspective on the Australian bush fires and was moved by the symbol of hope this person had. A longish but worthwhile read.

South Australia wind farms are covering all electricity demand at the moment which is happening more often: Wind Generation is 1,312 MW with Demand 1,161 MW. Exporting close to 500 MW to the other states.

I like the polls - great outlet for a serial lurker such as myself and they might even be accurate - look up "Wisdom of the crowd" or have a look at http://www.abc.net.au/catalyst/stories/4891962.htm

Does any know what has happend to https://robertscribbler.com/ which is giving a domain expired message?

Not sure if this is the right spot to ask this but Robert Scribbler is "a must read" for me along with this site of course.

Thanks Sleepy - interesting to see what people do to keep their towns functioning in cold climates. My kids have never seen snow but have experience plenty of days over 40 C.

I'd be a bit worried about where all the melt water will go  :o

Hey TerryM I'll happily store your ill gotten gains as SolarCoin if you like.  I've only got 20 coins so far which at about 15 US cents is not going to make me rich. But perhaps they'll be like bitcoins and sky rocket in value. Then I can repay your funds and keep the interest :)

Curious if any one else has come across SolarCoin and if it will drive investment in renewables which is the aim of the crypto currency.

Not sure I agree with the guardian article as many EV drivers -myself included like to make as much use of our regenerative braking as possible and barely use our brake pads. I have a Nissan Leaf myself but some models such as the BMW i3 let you come to a complete stop with regenerative braking so no brake pad use (and no particulates emited) at all.   8)

Policy and solutions / Re: Nuclear Power
« on: August 05, 2017, 03:07:11 PM »
I was actually searching for the maximum water temperature for cooling a coal fired power plant and came across this article which I thought was interesting - http://www.world-nuclear.org/information-library/current-and-future-generation/cooling-power-plants.aspx

As we warm up I've been wondering if we might hit limits on being able to cool fossil fuel (and nuclear) power plants but seems the steam cycle has a way to go yet. However efficiency goes down so economics (the mighty dollar always rules) comes into play plus environmental policies thankfully have some limits to stop everything in a local water source being boiled to death by the local power station.

Wow  Neven I so agree with this and have done so for quite some time.

For wages perhaps it could be achieved through a requirement of business / corporate registration, access to markets etc. that the organisation must have a ratio of highest wage level to lowest wage level of no more than 5 times.

I'm not sure how business owners wealth through shares could be managed perhaps a similar ratio for maximum share owned.

Antarctica / Re: Sea Ice Extent around Antarctica
« on: February 08, 2017, 01:09:15 PM »
Thought I'd have a shot at this:

Jaxa Sea Ice Extent for 7/02/2017 is up a little at 2,355,011 km2.

Hope I'm sourcing this correctly from https://ads.nipr.ac.jp/vishop/#/extent

I voted <2 as I see anything below that as essentially zero sea ice and made up from glacier and shelf ice that has broken away.

I put the dogs droppings in the compost which I've heard is a bad idea but I only use the compost on none food areas so I hope it's not an issue.  I've never had a detailed explanation why dog poo is bad in compost. Anyone know why?

Apologies if this has already been posted but I'm half way through reading this (it is longish but a good read so far) and it seems very relevant to this topic.  I find the similarities to Australian politics and society quite profound with our Liberal party a carbon (pun intended) copy of the Republicans and Labour with the Democrats. I vote Greens myself and keep on hoping that more of us will do the same but as usual was disappointed at the last election. Just about everyone I spoke were sick of both the major parties but still voted for them.

I have a look at the NASA Sea Level Change Page now and again and I think the Global Mean Sea Level has moved up from 3.4 to 3.5 since I last looked (but it could be my memory failing :) Also a good article on how persistent low pressure and a change in wind patterns could be having a dramatic local affect on sea levels North Eastern coast of the US.

Here in Adelaide, South Australia the day our last coal fired powerstation was finally switched off - http://reneweconomy.com.au/2016/last-coal-fired-power-generator-in-south-australia-switched-off-88308.

We've had a big storm with associated storm surge 1 meter above the highest high tide.  A bit of an eye opener for some with coastal property of what is just around the corner.

Yah this map is great - I finally know where and what people are talking about - at least a little better anyway. Thanks very much :)

The rest / Re: 2016 Predictions
« on: December 31, 2015, 05:59:11 AM »
Ok here are my predictions for myself which I can be slightly knowledgeable about  ;)

1. My itsy off-grid shed made up of hand me down / cheap ebay purchases of batteries (~60ampHrs), 60 watts solar panels and a 300 watt wind turbine (currently located in the wind shadow of the hours  :-\ will get a serous over haul to become 200 ampHrs battery (probs AGM lead acid as lithium still to pricey) 200 watts solar and the turbine goes up on the roof where it can do something useful.

2. Install a more convenient permanent charging option for my electric car (Nissan Leaf) rather than using the portable charger and extension cords   8)

3. Add 1 to 2 more Kw of roof top solar to my current 3 Kw of grid connected panel to get me in credit on electricity bills rather than just missing out in summer and still paying 200 - 400 (Aussie dollars) in winter.

4. Add grid connected storage similar to /or use a Tesla powerwall (probably a pipe dream and out of budget for me but you never know)

5. Get more serious with my home grown food which is currently a bath tub hydroponics (supports a gold fish, some yabbies, parsley, rocket and a marsh lilly), Numerous pots of fruit trees, herbs and various veges.  Not sure how to scale up as I'm in a small unit but perhaps the hydroponics is the best bang for my buck and space.

Ok and on to the big picture stuff that I have only the skills of a "Master Lurker" to help me with  :o

1. In my neck of the woods (Adelaide - Aus)our nasty season of bush fires will continue and enter the records as the worst to date.  Unfortunately this will include additional loss of life.

2. Antarctic melt season will produce a record mass loss for the ice sheets and another ice sheet will disintegrate perhaps unexpectedly on Eastern Antarctic Ice Sheet.

3. CO2 ppm will hit a record high several time in a row. As will Methane levels

4. El Nino conditions will linger and not fully disappear until June / July bring at least one more massive storm system all the way to the North Pole as we have just had. Giving a record low Arctic sea ice max and the sea ice extent will melt to less that 2 million km/2 so effectively ice free.

5. Most countries will be making very positive noises about taking action on climate change but it will much less than what is needed.
