  I read it all and even what is stated is mostly wrong UNTIL THE EXACT UNIT IS SPECIFIED. And I'd know because I have to work with this IN ORBIT. I've had this conversation a dozen times in meetings with military and government.

A snickers bar has nearly 5× TNT’s energy per kilogram—TNT merely has the habit of being extremely impatient about releasing it.

  I'm still surprised we haven't figured out a bioreactor you can feed your scrap food and turn it into energy, methane combustion notwithstanding. Like imagine feeding a roomba some sugar and it's set for a few days lol.

    You could probably even power a time machine without needing plutonium.

    But only if said Roomba is unable to find enough sugar on the ground for a few days. Otherwise, it's completely self-sufficient, you just have to leave enough crumbs on the floor.

    Lots of experiments along those lines, actually.

Gasoline, when in liquid form, is not mixed with oxygen and burns, releases energy slowly. In comparison with TNT which is both the fuel and oxidizing agent releases energy very fast, it has detonation velocity of 6,900 m/s. https://en.wikipedia.org/wiki/Table_of_explosive_detonation_velocities https://en.wikipedia.org/wiki/Table_of_explosive_detonation_... There is a way how to use the energy density of gasoline for explosive purposes, Thermobaric weapons. "A fuel–air explosive (FAE) device consists of a container of fuel and two separate explosive charges. After the munition is dropped or fired, the first explosive charge bursts open the container at a predetermined height and disperses the fuel in a cloud that mixes with atmospheric oxygen (the size of the cloud varies with the size of the munition). The cloud of fuel flows around objects and into structures. The second charge then detonates the cloud and creates a massive blast wave." https://en.wikipedia.org/wiki/Thermobaric_weapon https://en.wikipedia.org/wiki/Thermobaric_weapon
