为了使蓝杆菌51142更有效的工作，伦兹建议对其进行基因改造，使其包含更有效的氢化酶，以减少氢的损失。

51142 work better, Lenz suggests genetically modifying the bacterium to contain a more efficient hydrogenase enzyme, so less hydrogen is lost.

锂离子电池能保持电量。同锂氢电池每个月损失20%的电量相比，锂离子电池组每个月仅损失5%的电量。

Theyhold their charge. A lithium-ion battery pack loses only about 5 percent of itscharge per month, compared to a 20 percent loss per month for NiMH batteries.
