查尔斯·米勒建议，尝试基因工程在光感大肠杆菌里基因物质，而不是在利用可以进行光合作用的蓝藻的基因的犹他州立大学代表队说，最终目标应该是制造以成本更低的疫苗和藻类为基础的“绿色”燃料，不像大肠杆菌那样，蓝藻只需要水和阳光的生存来源，而不是碳水化合物。
Miller says the ultimate goal is to make it cheaper to produce vaccines and algae-based "green" fuels. Unlike e. coli, cyanobacteria only need water and sunlight to survive instead of a carbon source.

从2000年到2007年，以农产品为基础的生物燃料生产增长了两倍以上，现在已经占到世界运输燃料消费量的近2%。
Biofuel production based on agricultural commodities increased more than threefold from 2000 to 2007, and now covers nearly two percent of the world's consumption of transport fuels.
在现实世界里，氢动力汽车迄今为止尚未获得成功，其部分原因是缺乏续加燃料的基础设施、成本过高以及最近偏好电动车的政策摆向。
Hydrogen cars have so far enjoyed little real-world success, due in part to a lack of charging infrastructure, cost and - more recently - a political swing towards electric cars.
美国的交通基础设施亟需全面翻修，同时也存在很多优秀项目能够提高能源利用效率或增加替代燃料资源。
America's transport infrastructure is in need of overhaul (see article), and many worthy projects exist that could boost energy efficiency or alternative fuel sources.
这是以大多超大质量黑洞形成过程与恒星质量的黑洞的形成过程类似的假设为基础的。 这种黑洞的形成通常在大质量恒星的生命过程的最终阶段（用尽了用于核聚变的所有燃料的时期）。
This was based on the assumption that SMBHs form in a similar way to stellar-mass black holes, marking the final phase in the lifespan of massive stars that have exhausted all their fuel for fusion.
为成功制造这种生物燃料，科学家只能对大自然母亲进行改造。 他们可以在现有微生物品种的基础上进行筛选，甚至人工制造全新的微生物品种。
Scientists will have to improve on Mother Nature to make a successful biofuel, tinkering with existing microorganisms or even building brand-new ones.
