p>Some people believe that condoms cause AIDS. The argument goes: if you banned condoms, then people would stop

being promiscuous – if people stopped being promiscuous then AIDS would stop spreading.

While this argument has a certain internal logic, it has problems when it ventures out into the real world.

At the risk of getting caught up in a heated discussion about people’s strongly held beliefs, I think it is

worth raising this example. I recently spoke to scientist working for Greenpeace about the process I am proposing in order to understand what their concerns might be. His response was that it was wrong to raise the prospect of methods of removing carbon dioxide from the atmosphere, for fear of people thinking that they did not need to change their behaviour. Only by people changing their behaviour would it be possible to prevent runaway climate change.

There are two flaws in that argument: firstly, it may not prove possible to get people to change their behaviour in the time that we have left and secondly, we may already past the point of no return – we may already

be ‘infected’ with runaway climate change and it is only a matter of time before it becomes apparent.

moral high ground is a co

University’s Smith School of Enterprise and the Environment.

The first half of the seminar was a talk explaining Cquestrate, while the second half was given over to a question and answer session, with some tough and incisive questioning from those attending.

I recorded the first half of the seminar which you can see here:

Although the Cquestrate process is actually fairly simple to understand on a basic level, we’ve had feedback asking for more visual tools help explain what is being investigated. We think this animation does a great job of that.

It was put together by the Birmingham-based Eight Eyed Sea Bass. They’re quite rightly very proud of their work and have written about it on their blog. The audio was provided by The Audio Suite, also based in Birmingham. We’d like to thank them again for their hard work in putting this together.

Cquestrate is continuing to push

forward and develop a process

that could make

a hugely positive impact on the world. There are still areas where help is needed and we could do with more people hearing about our work. Please help

us spread the word.

We’d like to thank the following people for passing the video on already:

industrial or environmental area.

The second is the challenge

of addressing environmental regulations that didn’t forsee introducing large quantities of chemicals to the oceans as being beneficial.

The questions

We believe the questions around intellectual property are pretty much answered. However, the environmental law issues are trickier. We need to know:

1. What legislation (whether it be international, EU/a similar organisation or national) prevents large quantities of chemicals (calcium oxide and/or calcium hydroxide) being added to the
   Continue an after close three product viagra price and look again used my concealers…

   oceans?

2. What steps have been taken to relax those laws to allow the addition chemicals that would have a beneficial effect?

What we need

We’ve contacted some excellent lawyers who have provided a quote for their services in answering these questions. Unfortunately Cquestrate’s initial funding (provided by Shell) won’t cover this cost.

We are looking for:

• An environmental lawyer or team of lawyers; and/or
• A pro bono group who are concerned with climate change/the environment

to take this on as a pro bono opportunity to be conducted in the open-source spirit that Cquestrate has adopted.

We can only offer recognition as a valuable contributor to a project that may just address one of the biggest challenges of our time.

environmentalist would normally recommend – it is

wasteful and generates greenhouse gases – but do not worry because the boats that I have

burnt are metaphorical and not real.

I have resigned from my role as a management consultant at Corven (www.corven.com) and am now working full-time on Cquestrate. I have sufficient funding to take me through until the

end of the year, by which point it should be clearer what the prospects for this process are.

The last few days have seen some really interesting leads emerging, especially around the area of growing

algae. The waste products from the

calcination of the limestone are low grade heat and carbon dioxide, which are two things that algae need, so the process has strong synergies with improving the efficiency of algaculture. Watch this space for more updates.

Use the carbon dioxide generated from the first step of Cquestrate’s process to allow you to grow algae (the availability of carbon dioxide is the rate limiting constraint if you have even a moderate amount of sunlight). Vent off any oxygen generated from photosynthesis and then decompose the algae in anoxic conditions (no oxygen) – this will generate methane. With solar irradiation at 20MJ per m2 per day and an efficiency of converting sunlight to chemical energy of 1%, you are able to generate 730GJ per ha per year. Wholesale prices for methane are ~USD10 per GJ, so you have a per hectare yield of ~USD7,300. Farmers would be delighted with that kind of yield.

Now, it isn’t quite that simple – there are high capital and operational costs involved in growing algae – but there are reasons to believe that producing methane will be far cheaper than producing biodiesel (although biodiesel sells for more). For a start, if you want to produce biodiesel you have to get it out of the algae cells, by breaking down the cell walls

and using solvents, which involves energy and expense. Methane

by contrast is a gas, which will separate out without the need for any expensive processing.

Another benefit is that

algae don’t by choice produce much of the lipids that you need to produce biodiesel. You have to stress the algae, by making the conditions in which they grow abnormal. Photoynthesis yields sugars – the algae then have to go through a series of biochemical steps to convert those sugars into lipids – and each step reduces the overall energy efficiency conversion from sunlight to chemical energy. By contrast, to produce methane all you need to do is to allow the algae to do what they do most naturally – produce sugars – and then allow them to decompose (this is helped by two sets of organisms – the first set

breaks sugars down into acetic acid and the second set breaks acetic acid down into methane and carbon dioxide). The energy efficiency of this decomposition process is, in theory 95%, but in practice is closer to 80%.

Current

projects which seek to produce biodiesel from algae use

the flue gases from power stations as they

are a concentrated source

of carbon dioxide. This means that the algae needs to be grown near the power station and that tends to mean high land prices. Cquestrate’s process can be performed on cheap

land far away from a power station as its source of carbon dioxide is from the calcination of limestone.

be used to help grow algae – either for food or for biofuels. It also allows the growth of

biomass in very dry environments. How so? Think of it this way:

Say you wanted to grow a crop in an arid environment – you haven’t

got much water, so you seal your water and the crop that you are growing inside a greenhouse. Sealing it up stops the water

evaporating away, but as the plants grow they use up all the carbon dioxide in the greenhouse. So you decide to put some fresh air into the greenhouse, but when you do this you have to remove the old air, and when the old air leaves you lose all the

moisture … back to square one – it doesn’t work.

If, however, you have a sealed tank of water and into it you introduce pure carbon dioxide, you are in a much better position. The tank has a transparent lid, so you have sunlight; the water in the tank contains algae – you have everything you need for photosynthesis. Because the tank is sealed you will not lose water by evaporation. (You will need to vent off a small amount of oxygen generated by the photosynthesis, but you will only lose a small amount of moisture because of this).

Some fairly simple chemistry shows that for every kg of sugars that you produce, you need to use 600g of water. Undoubtably, you will lose some more water in the practical application of the process, but the water usage will be less than 10kgs of water for every kg of sugar produced. This sounds like a lot, until you realise that growing crops in really dry places like Egypt requires 1000 kgs of water for every kg of crop produced.

Or to put

it another way, it is possible to grow crops with 1% of current water usage.

So, paradoxically, the way to make the deserts bloom is to heat the right kind of rocks up.

  a?

  and that’s thanks to an excellent article on the German website Jetzt.de

• Within 24 hours of the project launching publicly someone had translated the press release into Spanish.
• Another Spanish article appeared on Neofronteras.com
• Lenta.ru ran an article in Russia
• The French version of Gizmodo featured Cquestrate and there was also a discussion in a French forum
• We’ve also come across mentions in Japanese and Dutch.

As and when I come across articles about Cquestrate they are tagged using delicious and then featured on the Cquestrate links page.

We may get to the stage where it would be useful to have the content on this site translated into as many languages as possible so our international visitors can get the most from Cquestrate. That may be part of

the next phase of the website. If you have any other suggestions to develop the site please use the comments below or go to the dedicated website development page.
