全球粮食供应的大幅扩张将需要与绿色革命具有类似影响的新进展。终极海洋牧场设想通过海洋热能转换（OTEC）的方式，通过人工上涌深海营养物质来提高公海生物生产力；食品将通过综合“浮动放牧平台”的管理而衍生，这也可以增强大气二氧化碳的固存和光带的净氧气产量。一些必要的技术已经存在；有些必须加以发展。将需要将这一概念商业化；这反过来又需要尽可能充分地整合创造价值的活动。根据典型的生态参数和一些只能通过研究来评估的假设，我们估计，一个假设的10兆瓦OTEC工厂的抽水能力每年可以生产大约330万美元的水产食品。这不是一个很大的投资回报，但它先于研究和工程开发；将生成其他值。粮食问题的紧迫性和缺乏消除障碍表明需要进一步评估这一概念。
Significant expansion of global food supply will require new advancements of similar impact to the green revolution. The Ultimate Ocean Ranch envisions enhancement of open-sea biological productivity through artificial upwelling of deep-ocean nutrients by means of ocean thermal energy conversion (OTEC); food products will be derived by management of integrated "floating grazing platforms", which could also enhance atmospheric carbon dioxide sequestration and net oxygen production in the photic zone. Some of the required technologies exist; some must be developed. Commercialization of the concept will be required; this in turn will require the fullest possible integration of value-generating activities. We estimate, from typical ecological parameters and from some assumptions that can only be evaluated through research, that about $3.3 M in aquatic food products could be produced annually from the water-pumping capability of a hypothetical 10-MW OTEC plant. This is not a large return on investment, but it precedes research and engineering development; other values will be generated. The urgency of the food problem and the lack of nullifying obstacles indicates further evaluation of this concept.
