"I am here today because I believe algae can be a solution...I'm convinced someone here will break the code. The exciting part is to see over 600 people in this room solving the problem. In fact, someone out there may have already solved it and I just don't know yet."

Just a thought or a warning if you will.

Non-stop selecting an algae that grows faster will result in a super fast breeds of algae species wich inevitably will be released in the oceans around the world. Wich once in the open can pontenitally clog the oceans.

We have example of that with an algae that was selected for small aquarium than sold all over the world. The problems begun when the owners had to clean their aquariums by dumping all the content into the sea/rivers. Thus spreading this algae all over the world. I cant remember the name.

I see this potential threat here.

Again, there are significant technological hurdles to be overcome before this technology is ready for market. It would be helpful for RE World to drill into those tech questions to report on the progress being made in overcoming those hurdles.

One question is how to process wastes in-situ so that the algae don't choke and die on their own waste products?

re: comment 1

Your concerns can not be hand waved away.
However, keep in mind a highly selected species developed under specific and constantly controled conditions, will not have the same properties living in the wild.
For billions of years indigenous algae were also subjected to non stop selection. Those that grow fastest take over the pond.

I agree with you to some extend. But man-made selection have proven to be far superior than the natural selection. Also as with the most of the crops this algae will be selected (and maybe genetically modified) to be resistant to illnesses and parasites.

Also the current overfishing can help the growth of these super-algae species.

I watched an NG movie about such algae that was poisonous to all kinds of ocean snails and was intentionally selected this way so it can survive the home aquariums. Later was released in the open. And the problems began.

Same concerns as of the genetically modified plants should be used here but with greater concerns since most of the ocean is excellent example of "not in my backyard" problem. As we can see it with the overfishing.

I believe that the fast spreading Rock Slime(new England) is now considered an invasive species.

Growing other species may now require permits and isolated habitat.

Of course, any such species would have to be kept within highly controlled areas and boundaries with stringent protocols in place to prevent it from escaping to the oceans. As long as strict laws and methods are developed and upheld, I think it sounds wonderful.

It can be easily solve the concerns expressed in this. The algae can be broken down and used to other purpose such as methane for energy production and other useful chemicals.

Therefore, people who are concerned about the wastes should rest in peace.

Hi

I would like to tell you about Nualgi.
This is a micro nutrient that causes blooms of algae.
It can be used to grow Green Algae for biodiesel or Diatom Algae for cleaning up polluted lakes, rivers and oceans.
Just 1 kg is required for 4 million litres of water, so its very economical.
Diatom Algae are consumed by zooplankton and these by fish, so there is no residue.

If Nualgi is used - human waste, animal waste and fertilizer runoff and CO2 can be converted into food or fuel in any waterbody.

Please see my blog www.nualgi.blogspot.com for more information.

How about burning or electrocuting the waste?

Based on the previous comment, it seems that this will be one industry that must be regulated as carefully as the nuclear industry. Perhaps the algae plants can be located way out in the desert, like certain places in Nevada where the dry washes never reach the sea.

I understand concern for evasive species. But I believe if we stick with a species that is indigenous to that area. We would be capable of relpacing the chemicals that we use from carbon based fuels.
What I believe is that we can grow the chemicals and by doing so replace the oxygen in the atmosphere. They are like a filter for CO2. A cattalic converter for stationary carbon burning heat and power generators.
I believe if we grow the species that is native to the enviroment but in a hyper state. It I is posable to grow certain chemicals for pharmacies, plastics, vitamins,fish food, animal food,and fuel.
