Could power be generated using the temperature difference in venus's atmosphere? On Venus the surface is around 467 degrees Celsius. At the top of the atmosphere it is much cooler, and at around 60 km above the surface the temperature is around 40 to 50 degrees Celsius. This is a large difference, and I think it could be used to generate power. Could one build a structure to harv... (more) |

Would a Dyson sphere be useful as a means of power generation? I have heard people (quite possibly on this site) say that by the time a civilization is able to make Dyson sphere it will be useless to build one for power and energy needs. So, would a civilization which can easily make a Dyson sphere make one for energy production, or would they have already have ... (more) |

highly resistant metal or other material in late 1700s What metal or material could be used to make super high-pressure canisters in the 1700s? It is for use as a fuel or propellant for a piston-driven engine to power vehicles, due to the fact that a gas canister is much lighter than the steam engine used to fill the canister. Bonus Question: To what l... (more) |

What materials and what shapes should be used for struts inside a vacuum airship's envelope? What materials and what shapes should be used for struts inside a vacuum airship's envelope? The vacuum airship is a theoretical dirigible design were you replace the hydrogen/ other lifting gas with a vacuum. The density of air at standard temperature and pressure is 1.28 g/l, so 1 liter of displac... (more) |

Could we move a gas giant by venting its gas? Could humanity move a planet such as Jupiter by forcing it to vent its gas? Assuming we have the technology to do huge mining operations and use these to make some of Jupiter's moons into a huge tube going deep into Jupiter. This tube would carry the gas from the mid area of the planet to space. cou... (more) |

Could an electroreceptor organ work above water? Could a species with an incredibly advanced electroreceptive organ (such as that of a shark) be able to use it above water? The gas-mix in which the sense works must be breathable to humans, and it would be good if it was the same mix as in the earth's atmosphere. (more) |

How could a self contained organic body propel itself in space How could an organic, plant-like, intelligent organism move around space? Assuming that the body is inside a small meteoroid and that outside of the meteoroid is covered in tessellating leaves to gather sunlight, to allow it to survive. Since this organism would have to have to conserve matter an... (more) |
