Lactose Intolerant Individuals may prove a bonus in Space Missions. Lactose intolerant individuals have huge problems with gas from the inability to process certain dairy products and foods. Therefore such an individual after eating will create gas, methane, which could be used as fuel. There are methane based fuel cell units available and a few companies, which have such portable devices now. And some will be online soon;

Hydrogen can be generated from methane. That lactose intolerant individual maybe much more valuable than once thought. By using this gas as a source needed to run a fuel cell we may also help keep batteries charged in space craft for explorers, army communications personal and for survival situations. The human body has the ability to generate waste and if properly monitored, stored and re-used it may just be enought to keep them alive and powered up.

As NASA explores ways to power up space colonies and allow ways for explorers to survive the deep of space, all options must be left open and maybe some body orfices too? Currently scientists and researchers are trying to figure out ways to recycle and reuse body fluids, human waste and water for long-term space travel? Some day you may wish you were lactose intolerant, but for now keep the hot air coming. Just sit next to the other members of the crew.
