Paying for the floods: Rail devolution? and a billion dollar cut to solar power
Now that the flood clean up is well under way, governments are looking for ways to pay for all the infrastructure repairs that are needed, while I'm not planning on commenting on the federal government's flood levy I do want to look at some of the cuts.
In SEQ the biggest causality of the floods (so far) has been Cross River Rail, the $8.2B project to put a second rail link from Brisbane city across the river and so massively increase capacity on the "Gold Coast, Beenleigh, Cleveland, Ferny Grove, Airport and Doomben" lines. This project had been seen as essential because the one current north-south rail bridge into the city, the Merivale bridge, is expected to reach capacity by 2016 after which there will be no room for extra peak time services. By delaying the four year long project for several years there is now no way it will be finished by 2016, assuming it is built at all (given that "several" years is a long time in politics). The implications for expanding the SEQ rail network are not good.
The cross river rail was to be the centerpiece of the State Governments long term SEQ transport plan, which ironically, had its main focus on a "rail revolution" and on increasing the sustainability of the transport network.
At the federal level things aren't any better with many the axe falling on many climate change and clean energy programs. While I'm not particularly sad to see the scrapping of "Cash for Clunkers" (an extraordinarily expensive way to reduce greenhouse gas emissions) what you probably didn't know was that this program was "funded" by raiding ~400 million from solar power programs in the first place. Now solar power has been cut again by the tune of another ~500 million. The net result is an almost billion dollar cut to solar power programs. Also cut was 230 million dollars from the Green car fund.
The government appears to be hoping the introduction of a carbon price will mean these clean energy cuts won't matter. This seems naive. Although a carbon price is widely regarded as the cheapest and most effective means to cut carbon we shouldn't consider it a magic bullet. In the short to medium term, even with a carbon price, the first installations of large scale solar will likely require some government assistance in the deployment stage. The Solar Flagships program is designed to do this and is now ~250 million dollars poorer.
Headslapping really begins when we consider the wider implications. Climate change likely played a role in exacerbating and/or increasing the likelihood of these floods. The government response to which has been to cut to climate change mitigation and sustainability programs to pay for the damage. I find myself in agreement with this commenter who said this is "like putting off a hospital visit for a serious wound to pay for some more bandaids".
Obviously hard decisions need to be made to find the money required for the flood recovery, actions, though, say a lot about priorities.
Not happy? You can contact the PM here.
PS: These are my personal opinions.

Foodconnect demonstrates the resilience of local food - business essentially unaffected by the floods
Listen to Foodconnect founder and local food visionary Rob Pekin talk on ABC radio about how Foodconnect was able to keep getting it's fresh fruit and veges from farmers to customers (including by boat and canoe when necessary) during the floods.
Pekin explains how the strong connections between local farmer, Foodconnect and local customer give it the agility and resilience to get food to people when the bigger players can't. Just one more reason to like Foodconnect, along with the benefits of getting fresh food from local farmers who receive a fair wage in return.

Esacalating food prices? Plant some Seeds!
Escalating food prices are a great impetus for us to take some steps towards helping ourselves by having some food in the garden. Its easy, fun and addictive. Just watch those seeds sprout!
We will be having seedlings for sale at our stall at the Moggill markets on Feb 19th, so if you any to spare & share please bring them along or contact Carol cshantal@gmail.com
One of our TT folk, Laura Willet, has taken the plunge and shares the following:
Some simple tips for growing your own
When sowing seed, add 1 teaspoon of epsom salts to the watering can.
This gives the seeds a growing boost. Save those cardboard egg cartons for sowing your seeds.
Save your own seeds. “The Seed Savers Handbook” - Michael & Jude Fanton, is a handy tool.
Save, share and swap seeds with family, friends and neighbours. How many of us throw out or compost seeds from pumpkins, pawpaws, tomatoes, cucumber, to name a few?
Join BOGI - Brisbane Organic Growers Inc. BOGI meets on the 1st Thurdsay of every month at the Peace Hall, 102 McDonald Road, Windsor. Ph: 33573171; www.bogi.org.au
This is a great organization offering organic seeds, gardening books for loan and sale at cheap prices. Guest speakers, every month, speak on different topics, which certainly gets one thinking. Members are very friendly and helpful. Meet some long time members who have been gardening and growing their own for years, and also teaching others. The monthly newsletter is a great source of information and a very good read.
Join a community garden. (Yes Laura, we have been trying to get one locally for quite some time!- Carol)
The BCC website has links to various groups throughout Brisbane. There may be one just around the corner from your place. Like minded people, who are friendly and only too willing to share their knowledge and experiences.
BCC holds free workshops throughout the year on a variety of topics. Composting, worm farming, keeping chickens, growing organically, to name a few. Your local library will have brochures giving dates and venues.
It is very satisfying watching seed you have planted, emerge from the soil and grow into a plant. It is even more satisfying to eat your own, self grown produce.
More importantly, just have a go.
We all start somewhere. Not one of us is born an expert.

Resilience in electricity when the power grid fails
During the recent floods many were without power for 3 or more days. Some are still without. Here are a few ideas you might like to implement depending on your budget.
Five levels of security
1/ Recharge your mobile: In-Car charger <$10.00 or small solar powered charger $40.00 http://www.multipoweredproducts.com.au/products/HYminiSolar-%252d-HYminiS.html
2/ Run a laptop from your car: Cigarette lighter inverter ~$80.00 http://www.excelsiorpower.com.au/prod175.htm
3/ Run a small 12 volt camping fridge: Solar panel (120w) http://stores.ebay.com.au/Bit-Deals, regulator and battery $800.00
4/ Keep your household fridge going: Solar array, regulator, battery bank, inverter
Solar panels (500w) $1500.00 http://www.lowenergydevelopments.com.au/products
Regulator (40 amp) $200.00 (available on ebay)
Battery bank (200 amp hour) $600.00 http://www.excelsiorpower.com.au/prod233.htm
800w pure sine wave inverter $200.00 http://stores.ebay.com.au/POWER-JACK-SHOPPING-CENTER
TOTAL COST $2,500.00
5/ Keep your house running with existing grid- solar system by adding a mini grid.
Add a generator change over switch $200.00
Extra solar panels (200w) $600.00 http://www.lowenergydevelopments.com.au/products
Battery bank (600 amp hour) $1,500.00
Regulator (20 amp) $100.00
800w pure sine wave inverter $200.00
TOTAL COST $2,600.00
Some alternatives:
1/ Buy a generator and use petrol or diesel which may not be available (use a changeover switch and connect up generator to house)
2/ Trade in your existing grid-interactive inverter for a Selectronics hybrid inverter http://www.sppro.com.au/ and battery bank for around $9-10k.
2010: Warmest/Equal Warmest and Wettest year on record
Some of us may have been more preoccupied with flooding but several of the groups of scientists who take the earth's temperature have now reported back on 2010.
NASA reports that 2010 was the warmest year on record (going back to 1880), but so close in temperature to the next warmest year (2005) that the two are in a tie due to the margin of error in their measurements. The NASA graph below shows the steady warming of the climate since the 1970's.
NOAA, (essentially the American equivalent of the BOM) also find 2010 to be tied with 2005 for the warmest year of record. NOAA do more than just temperature though and also reported the interesting finding that 2010 was the wettest year on record globally, which is at least partially attributable to the El Nino and La Nina conditions experienced in 2010.
Both satellite datasets measuring the temperature of the lower atmosphere (which are separate to the surface temperature above) showed 2010 as the 2nd warmest year behind 1998, although again the difference was within the margin or error.
Why do the satellite datasets, but not the surface datasets above show 1998 as being part of the record hottest? I believe this is due to the lower atmosphere being more sensitive to the short term warming effects of El Nino and cooling effects of La Nina. 2010 was mostly dominated by an moderate to strong El Nino, 1998 had a record strong El Nino, whereas the 2005 El Nino was weaker. Given this, it is no surprise 1998 is more prominent in the satellite data. The fact that 2010 essentially tied with 1998 despite a considerably weaker El Nino hints at the growing warming influence of greenhouse gasses.
Overall, despite a bit of jostling for top spot between individual years, the different datasets agree very well and show similar long term warming trends.
And for the future? This prediction is from the head of the NASA group measuring the earth's temperature:

Improving energy efficiency: LED downlights
 |
| A 12V halogen example |
One of the obstacles to replacing them is mine have an electronic transformer creating the 12V DC these things need (a small fraction use AC, and I replaced those, though with LEDs that aren’t that bright).
Last night, one of the 12V models failed again, so I decided it was time to reopen my look at LEDs. Some have appeared on the market that have better electronics and can tolerate electronic transformers, but they aren’t cheap. On one web site with prices, replacing all of mine would cost over $700.
It would probably make more sense in terms of cost to pull all of them out and replace them with sensible fittings but I’d like to explore LED options a bit before going that way.
I will add to this article as I find out more, but if anyone has hints or insights, please post comments.
