Zero Emission Ships

Idea Owner: Jose Luise Gutierrez - Garcia / Roy Wagner The idea is to create a fishing vessel that produces no emission or waste. These fishing vessels would be powered by clean energy like for example solar power. Marethix Industries SAS from France, is the first company launching the concept of zero emissions, zero fossil fuel for fishing boats and could be a great example for this concept....

Slow Mill

Idea Owner: Erwin Croughs Wave energy is one of the cleanest sustainable energy forms and has enormous potential for all oceans around the world. But it is also one of the least developed forms as waves are difficult to harness and have damaging effects on ocean structures. Slow Mill provides the long awaited answers to capturing oscillating motions effectively as well as ways to survive the harsh maritime environment. At the moment a scale model (1:3) is being tested 2 km off the coast of Scheveningen and plans to built the first commercial North Sea prototype are being developed. If current testing produces good results, we might very well have a game changer for the industry on our hands which especially when combined with wind energy, might revolutionize the cost of energy from our oceans.


Idea Owner: Bart Blijerverld The goal of the PolyMore project is to empower local entrepreneurs in Angola to recycle plastic waste in to useful products. Currently, a business model is being developed around two concepts for the recycling of bottles in to fishing nets, soil erosion prevention products, roofing tiles, sinks and gutters. There is local demand for these products so entrepreneurs an set up a self-sustaining businesses with this technology while reducing the amount of plastic waste in their surrounding. The PolyMore project is looking for partners who can help set up te business and a partner to assess any health and safety risks....

Protecting With Nature

Idea Owner: Felipe Leon We want to use certain macro fouling fauna as a coating barrier in order to isolate the target metal from the corrosive environment. In addition to this, the use of mussels will serve as an organic collector system which will increase the organic content in the sediment so that microbial processes will create a sharp redox gradient from which electricity (bio-electricity) can be harvested for cathodic protection. After approval of the concept phase, a prototype of the technology will be tested in typical harbor environments. Main advantages of this idea are more "natural looking" harbor and offshore infrastructure in addition to the low cost of operation (practically self-sustained by natural processes). The possibilities are big, considering that low corrosion damage has been incidentally observed at places were certain biofoulers are present. On the other hand, bioelectricity generated by microbial processes (microbial fuel cells) is a relatively well-studied phenomenon. Bioelectricity might not be realistic for the extensive human consumption but might not be realistic for the extensive human consumption but might be just enough for cathodic protection purposes....

Floating Cathedral

Idea Owner: Menno Broers The Floating Cathedral is a large-scale solution for harnessing wave power, combined with energy storage. The combination enables continuous power output, unique in the market of sustainable energy. It involves: 12 pontoons on the lower end of the construction to move along with the waves, the movement is then used to pump up sea water. The sea water is transferred to the reservoir on the top en of the Cathedral. The water is then situated at a level of approx. 50m. The water will flow back to the sea from the reservoir in a continuous way, while driving a set of hydro turbines. This way, the continuous water flow delivers a continuous power output. The whole construction a very large, approx 350 meter in length; the size of three soccer fields. It delivers approx. 50MW of energy , which is sufficient for 150,000 households. Due to the continuous power output, it also delivers the same output as a wind park with twice the installed power and a footprint of 24km2....
