Kelp? and water?

(adam ulbrich) #1

I think kelp could be a industry as it can be used as fuel and food.It could be a power source and an economy for sea steads.

and how would we get water if we were to live in a sea stead just a question.

Farming kelp is a brilliant idea, if the floating platform was a star shape you could have kelp growing on chains linked between them. With regards to clean water that’s easy: desalination by using solar to boil off the steam or use electrolysis to create hydrogen and oxygen. Store and then run them through a fuel cell to create electricity and pure water. When can we start😊


Kelp has been proposed and discussed many times. There is documentation in here on the how/where/whys of it, in many different places, including the archived olf forum.

Topics of interest in the context of Kelp and Water

• pyrolysis - processing of algea to bio fuel |

• LNG | Algea | biofuel | - the oceanic gas industry as the big energy integrator

• Oceanic industries | the big five | ENERGY

• Kelp and other algea will be the base of a carbon neutral fuel industry that is already emerging in form of the LNG gas industry and will replace fossil fuels altogether.

The carbon neutral biofuels will be produced in the vast ocean instead on agriculture land and the existing oceanic LNG industry will be the infrastructure backbone. It is not necessary to read a cristal ball to predict this - the technology frame is already emerging as we speak.

context worth to read:

• Energy buffers | ORES sphere | windpower to gas | gas to power fuel cells |
• Methan to liquid fuel refinery technolgy
• Wave Energy | pelamis | current turbine |

Algea to liquid fuel | waste to liquid fuel | industries require a vast amount of water, heat, and pressure, things that are expensive to produce at land but free delivered by geothermal processes at the mid oceanic ridges - seasteads will definitly exploit these opportunities.

Algae biodiesel?

Kelp has nothing to do with Liquefied Natural Gas.

There are 3 relatively easy ways to make fuel from kelp:

  1. press oils and use them, or convert to Biodiesel
  2. use kelp on biogas digesters, to make biogas/methane
  3. use it in a gasifier, and make CO

sorry i meant algae i dont know why i said kelp just got mixed up


Kelp is Macro Algae. Either way, Wil Ellmer was wrong about it having anything to do with LNG - Liquified Natural Gas.

Processing plant oils into fuel can be easy. Actually, once the liquids are pressed, and separated, the oil can be used (filtered) in diesel engines, as long as it is pre-heated. OR, the remaining pulp can be burned, preferably in a gasifier, to use CO as fuel, to obtain ash, which can be used to make lye, to use making the oil into biodiesel.

This leaves large quantities of glycerine byproduct, which can be added to a biogas digester, to make biogas. Once the volume of necessary ash is obtained (practice will teach that), the remaining pulp can be used as fish food, or fed to a digester, to make more biogas.

Many ways to recover most of the energy from biomass, such as Kelp and micro-algae. How involved you want to get is solely at your discretion.

Appendix 2
Proposed Regulatory Changes
Sections 165 and 165.5, Title 14, CCR
165. Harvesting of Kelp and Other Aquatic Plants.
(a) General License Provisions. Pursuant to the provisions of section 6651 of the
Fish and Game Code, no kelp or other aquatic plants may be harvested for commercial
purposes except under a revocable license issued by the department.
(1) Who Shall be Licensed. Each company or individual harvesting kelp and
other aquatic plants for industrial, human consumption or aquaculture purposes shall
apply each year for a license on forms provided by the department. Application forms
and a list of laws and regulations governing the harvest of kelp and other aquatic plants
are available on request from the department’s Marine Resources Division, 1416 Ninth
Street, SaefamentorGA-95814 Marine Region, 20 Lower Ragsdale Drive. Monterey CA
Beach Los Alamitos, and San Diego.
(2) Cost of License. See Section 6651 of the Fish and Game Code.
(3) Where to Submit Applications. Application forms, together with the $100
license fee, shall be submitted to the department’s Los Alamitos office at 4665
Lampson Avenue. Suite C, Los Alamitos, CA 90720, Long Beach office. 330 Golden
Shore, Suite 50, Long Beach, CA 90802.
(4) License Limitation. All provisions

With a boat kelp can be picked up.
Commercial license fee is $100.

There are open kelp fields for harvesters.
Drying and grounding the kelp can be done.

Now, it is just the question of a customer.
May be San Diego Zoo, Wild Animal Park would be interested.

That’s one part of the question. The bigger more complete question is ‘the market’, because you need more than one customer.

Essentially this is an agricultural business model, even though it’s a wild harvest. By this I mean you have a product that is seasonal (at least it grows more during certain seasons, one should also look into seasonal limitations on the harvesting license and weather patterns that would affect harvesting operations), spoilable, and meant for food/fodder. So the agriculture model fits as well as anything will.

So how many customers are there in the potential market, how many existing and how many potential? Is the market saturated with producers or is there an unsatisfied demand? What is the availability of product- are the existing harvesters taking all of it? Can the amount of kelp growing wild be improved by judicious “cultural practices” at harvest?

Are there grades of kelp that can be sold at a premium? Is there a fall back “commodity” market for excess? What about value-added kelp products (pelletized, bundled, baled, chopped, dyed, ground, sheets)? Can value-added processes be applied asynchronously (e.g. with excess product stored until a period of low demand or during bad weather) or do they require fresh product?

Does shipping cost factor into limiting your market? What are the communication channels for reaching customers? Is it a vertically integrated market or do you use channel partners?

These are some of the questions that would go into creating a business plan for a kelp harvesting business, I would think.

Look for business plan templates aimed directly at this, but don’t limit yourself. Look also for business plans aimed at wild harvest of other items: mushrooms, truffles, ginseng etc. It might give you some ideas on organization and marketing.

Hehe; well; so; all is good here. Thank you for the responses.

May be more about kelp.
It grows in not so deep water, about 50 ft (15 m).
It could grow in deeper water from underwater buoys to surface.
Buoys could be 1 mile apart in a 10 by 10 and/or a 100 by 100 miles matrix.

Kelp can be ground with a meat grinder. There are some industrial meat grinders.
Those are motorized version of 120V ac kind. I guess, the best to get kelp and
grind it right away on the boat, and them possibly dry it right away on boat, and
bring dried ground kelp as a finished product to port for animal feed.

Well, the kelp and the meat grinder works.
I tried it with a manual version. Motorized would be faster.


As with mangrove forests, your kelp beds would function as a Surface Wave Oscillation and Refraction Device … to eliminate the need for “floating breakwaters” (that don’t work under any configuration).

Consequently, a kelp bed surrounding a seastead would protect the seastead from surface waves, as well as provide a potential source of income.

Not to mention … the obvious benefits of establishing a natural wildlife habitat surrounding the seastead.

Keep on presenting your creative ideas, @spark.


Kelp could also be useful in biorefineries, to make polymers and other chemicals usually derived from oil and gas.

(Bob LLewellyn) #22

Not to mention it can be made into oil just like algae can. Oil for cooking or for burning to make heat for cooking, or fuel for our motorboats. In addition kelp fields will keep out pirates, if we ever had any. Can’t use props in kelp fields, have to use hydroplanes or rowboats. Sal Bank, again perfect for farming. Might even add a fish farm?
