The invention provides an artificial ice substrate that floats on a body of water. The top surface of the artificial ice reflects a portion of the sunlight back away from the earth. The bottom surface has nutrients for enhancing the growth of algae. Several weeks after placement of the artificial ice in the body of water, a ship with harvesting equipment, scrapes the algae off artificial ice and into a collection tank, re-applies nutrients to the underside of the ice substrate, and then deposits the artificial ice back into the lake or ocean. The marine plants are then converter into fuel. Besides creating carbon neutral fuel, this method provides carbon credits by means of reflecting sun energy back into space.
