    cal≠kcal

    1 gallon gasoline contains 31 million small calories, while the human caloric requirements are given in large calories. 1000 small calories = 1 large calorie. So the calculations are off by a factor of 1000. The confusion stems from the fact that both are commonly referred to as “calories”, for some stupid reason.

    So in reality you would have to drink another gallon in just 2-3 weeks.

    I didn’t do the math, but a person’s got to do more lifting in those 34 years than a car traveling 30 miles at 60 mph carrying 4000 lbs, right?

    So apparently they’re starting to create machines with biological parts. I wonder how long until we get artificial stomachs capable of using anything not explodey or caustic for fuel?

      In order of worst to best case scenario the human body will reject, wear down, or scar around any and all implanted foreign materials or objects. Implants of every type have a shelf life, some long enough to never worry about removal. The best method to secure implants are to bones, but the only nearby bones for the stomach are the hips and spine, with organ cavity linings being problematically in the way for most attachments. For the digestive system it would need to be extremely resistant to corrosion and it would also need to be nontoxic as it would inevitably enter the bloodstream. Even teeth fillings are only rated for about a decade at most.

      So, to be blunt, no such technology exists on this earth nor any speculation on how it ever might.

      Sorry did you mean powering a machine with food? We have those, there is a university somewhere that throws copious amounts of expired mayo into an Anaerobic Digestor which produces fuel for a combustion engine.
