G'day from downunder

[teraniageoff]

Hi Scientia-ists,

I am an ex-Industrial Arts teacher (US: "shop"), with 4 kids, and live off the grid, in a forest with 9kb/s download onto a mac iBook w 80GbHD. No crocodiles, but I have wrestled a huge goanna trying to steal the figbirds I was rehabilitating...

 

I arrived here looking at Eprida and char links. I make parabolic cookers as a home cottage industry, out of satellite dishes and scrap.

 

I also work with CCAN a climate change/peakoil group, making bigger dishes to 8m dia, from fibreglass, for CST Power at home, and 2minute pizzas. Our demonstration dish is an army akak gun spotlight dish, 36"dia focusing to 3mm, at a temp of >1,500 deg C. It cuts steel and makes magma out of road metal (dolerite?).

 

I am interested in the application of lots of clean, ethical heat to a biomass filled cavity, without oxygen,... and then + NH3 + CO2 + H2O.???

 

Haven't got a clue how to do the cyclonic synthesis of all that, at home, so I need to be pointed in the DIY direction of that process for the organic smallcropper. (preparing snow peas and broccoli beds now)

 

Especially if anyone has tried concentrated solar thermal applied here.

 

 

 

I am an avid reader of energybulletin.net, and it is ahead of google on my toolbar. As a result I haven't go so depressed lately, seeing the jostling for a good oil war, and the IPCC "news", as I've had a few years to go through the Kubler-Ross stages of grieving for the planet and my kids future...

Welcome to our site, we have more people from the down-under bush here. ;)

Hi Scientia-ists,

G'day from hereupper......................enjoy my friend.

Nice intro. It's a pleasure meeting you. ;)

 

 

Welcome. ;)

mean bastards goannas

They might make good eating though

Sounds like something out of James Bond. Where do I get one!

 

The pyrolysis plants keep the gas link closed and re-use gasses for further cooking of char

I will try to find some links. Google "pyrolysis" for starters

Well with Branson offering 25mil we all are now and will all keep it secret

Can't help. Not a DIY person. but keep watching Solar parabolic and Terra preta threads or start a thread of your own.

They will be fine, just tell them to keep their hats on.

Me too the best place

Welcome to hypography, we need more Ozzies the Yanks have no sense of humour B)

[Jay-qu]

Ditto Michael, us aussies are way more entertaining :D - perhaps its just our odd sense of humour though.. B)

 

Perhaps you already found us through the thread on 'solar parabolic ovens' but incase you didnt you may care to take a look at it B)

 

Welcome Geoff

Thanks michaelangelca,

The dish is unobtanium these days. 1/2" slumped glass, 1942, polished mirrored, backed in lead in a frame like the harbour bridge. i am working on lightweight ones. Cost thousands to reproduce. Optics are fun on wet/cloudy day...giant makeup/shaving mirror. A firey at the market sai his brother barbied the sausages on his in darwin.

 

been checking the terra preta thread and found heliopyrolysis and am googling...

 

The advantage of dishes Vs troughs is the concentration ratio gives very high temps that allows losses not to interfere with the high temps and flow rates that you want.

I like Branston's style. A larger than life Terry Pratchett-esque figure.

off to the solar parabolic thread.

cheers

My God he is not only Australian but a Terry Prattchet fan!

Wonders of wonders.

I have just decided I couldn't stand the geeks at his Melbourne Conference- but I was tempted

 

I'm sorry i can't find the pyrolysis links I wanted to send you

You might like to contact Dr. Stephen Joseph at "Best Energies " Somersby NSW and let him know what you are up to.

He is a mad engineer who has invented a great, industrial strength, pyrolysis machine

Thanks Michaelangeilca,

Yes a Pratchett fan from way back. Robyn Williams on acid doing Tolkien I try to say to people, but funnier. Don't tell me he was in melbourne. Might have to join the fan club. Definitely one of the top writers in my life. My son just visited and dropped me off the entire collection in a plakky tub. It's distorting time and space in the lounge room right now... now where's that shelf that leads to Branston's future library...

I guess you've read the globe if you're on this forum.

 

Will try Stephen Jpseph. Went to school with a Stephen Joseph, be funny.

cheers

Was the Globe the science of Diskworld?

TP is coming to Melbourne next month I think

The ozzie site is, I think, "Unseen University."

This is the British newsletter

The fan web site is bizzare!

Yes science of discworld, with every second chapter the science of Roundworld by a scientist (David Cohen?)

By the end I think I knew all science better, but actually preferred discworld thinking. i think humans do it a lot and that is TP's charm, his strangeness and uncertainty, to borrow some quantumese. I mean "The Colour of Magic". How could ANYONE resist that? octarine flavour... mmmmm.

 

Found you a lot on the terra preta thread, and also some disturbing points on pyrolysis pollutants and/but disadvantages of afterburners; getting tricky. Might be easier to just burn off badly..

PS. Amazing that I'm off to "Unseen University"...my alma mater I reckon.
