The linked website is empty? The ice aid really worth expanding and working out, but you do not have a lot of time. You need to explain well and in detail at least one of the conversion techniques and you need also kind of a business plan for such a plant - hope much will it cost to build one on a cement site, for example, how much will it cost to run it, what it will produce and how you can sell it, etc.

Hallo Anna
Thanks for the encouragement and sorry about the site - the site provider flipped out but I'm assured it will be back on line tomorrow. That does include some supporting numbers, so is linking to that sufficient?
I'm not in a good position to produce a business plan... my chosen career path means I now have no contacts able to advise on financials for something like this. My key argument would be that CCS is being implemented at high cost and pays back nothing - so a plant that offers similar benefits and would probably be at similar cost, but pays back large volumes of food or biofuel and produces life-giving O2 throughout its life must be better. My main site provides more info so I'll sort the link out tomorrow.
Thanks again for the input, I really do appreciate it! :)

UPDATE - work at Purdue Uni http://www.sciencedaily.com/releases/2014/07/140723152023.htm may be suggesting spinach would be a good choice of plant. I'll try and get some mass balance info, if I can I'll add to this.

STOP PRESS! http://t.co/gP3CgKTxtL, airborne water vapour magnifies global warming effects.
And much water vapour comes from burning carbon fuels; the equation for wood combustion (all carbon fuels are broadly similar) is C6H12O6 + 6 O2 = 6 CO2 + 6 H2O
So, it occurs that HCCAS recovers heat from flue streams. Flue streams are water-vapour rich, so when we recover the heat from the flue gas we ALSO condense out LOTS of water. Yes, it'll be acidic with CO2 and contaminated with combustion by-products like sulphur, but it's there and - I think - fairly easily treatable and cleanable. Most importantly, it hasn't gone into the atmosphere.
So we're adding *water vapour scavenging* to HCCAS's other virtues of
- CO2 reduction
- O2 production
- and food/biomass generation.
Not bad.

We have seen much work on growing algae with CO2 waste streams already -- what makes this approach different or novel? We would have also needed to see the key challenges more thoroughly addressed.

The key innovation here is as stated in the proposal; to use plants for CCS not just algae. I hope the judges took time to read this.
