移动能量转换器除了要求高转换效率和低成本外，还要求低质量。我们建议使用使用2d材料（如石墨烯）作为栅电极的热电子转换器。导出它们的比能量输出的最终极限，我们表明，正能量输出可能接近任何热量转化为电能的基本极限。这些转换器可以作为航天器的电源，加上真空外壳，用于电动飞机和汽车的发电。
Mobile energy converters require, in addition to high conversion efficiency and low cost, a low mass. We propose to utilize thermoelectronic converters that use 2D-materials such as graphene for their gate electrodes. Deriving the ultimate limit for their specific energy output, we show that the positive energy output is likely close to the fundamental limit for any conversion of heat into electric power. These converters may be valuable as electric power sources of spacecraft, and with the addition of vacuum enclosures, for power generation in electric planes and cars.
