A heat pipe system should be able to handle what your load. The advantage of heat pipes over many other heat-dissipation mechanisms is their great efficiency in transferring heat. A pipe one in...
The planet could have wildly inconsistent gravity. Gravity on Earth is non uniform, though it's hard to tell because of the variations are slight. But if this planet had a large super dense mas...
Since it is specifically for one set of wires, and carbon monoxide is caused by burning, then this set of wires could have a coating that is slowly burning when the power is on. It could be an insu...
There are (at least) four species that we know of that actually photosynthesize for energy Sea Slugs borrow genes from the algae that they eat through horizontal genetic transfer, and incorporate ...
Unpredictable weather with lots of microbursts, wind shear, tornados, and other unfavorable winds. Wind shear is one of the most dangerous things for an aircraft. Thankfully they are generally r...
Did a little reading and I think what you're looking for is the corona effect. This is caused when the voltage is high enough to cause ionization in the air surrounding the line, which is caused "...
Cut a road into the canyon walls. In order to build stuff on Mars, they are going to need a lot of heavy earth moving equipment. Simply start digging/mining along the edge of the canyon, and mak...
Maybe if the magic/technology let them move the orbit out a ways during the red giant phase, and then in much closer as it became a white dwarf
I think it depends on what orbit it is at. For instance if it is at a low orbit and spun up to create artificial gravity, then once the ring is broken the remaining pieces will fly away by their ow...
A lot of these answers talk about how colors and shapes can mean different things based on region. But if it's a standard schema across all robots, then that doesn't matter as much, because people...
So having a man made island that can sink and float isn't hard by having buyancy chambers like a submarine, and having force fields to keep the water at bay could keep it dry and habitable even whe...
Late answer, just found this article: Nasa Proposes Magnetic Shield For Mars The important bit from the article: Ask scientists why Mars is cold and dead and they'll usually point to the dea...
Couple possibilities: Photonic Matter - It is possible to take photons (light), which are massless, and bind them together so they behave as if they have mass. It may even be possible to arrange t...
I think if the planet had an atmosphere that was very thick to keep heat in at ground level, heavy in hydrogen and helium, with a very strong magnetic field to keep solar rays from knocking them aw...
So you set it up like a drug trial. First phase is really small, maybe 10 people to get dosing figured out. Maybe use some underprivileged people who would like a place to sleep and some money. If ...
You might not want them following you home You never know what you might run into out in the deep of space. If you come across a new civilization that would pose an imminent threat to humanity, su...
There is one way that we know of that can make this happen, which is tidal energy. Jupiter's moons Ganymede and Europa both have a lot of water, as does Saturn's moon Enceladus. As they orbit thei...
Keeping it on mars, one easy reason is flooding. If they are there teraforming, things start to warm up, a lot of permafrost will melt. That water has to go somewhere, and the most likely place is ...
So wind wise, you'd have Hadley cells that extend around the planet. Basically hot dry air on the sunward side would cause the air to heat up, rise, and make a low pressure area. Meanwhile on the f...
So start with a planet that is mostly made of a metal with a low melting point, say lead. It's set close enough to a star that during the day the surface becomes liquid, but it also has a low rotat...
Use the vacuum to help cool the ship. Specifically, have several enclosed/mostly enclosed spaces that are transparent to IR and that is pumped to a vacuum. Use water to absorb the heat, and then sp...
So I think a two prong attack. First prong is to remove all the defenses, and an easy way to do that is with EMP's. Launch nukes on SCUDS from container ships 25 miles up over the continents and...
Learned behaviour. Like staking an elephant or Pavlov's dogs. When the dragon was young and more fragile it had a bad experience with some trappers who thought it would be fun to hurt it with fire...
So in general terms, if the planet was like Earth in size and atmosphere, but had an orbit of .8 AU's instead of 1 AU, then the planet would have an average surface temperature of Kelvin: 322, Cels...
Start with pulsar planet like the ones that formed around the pulsar Lich, but a little further out and tidally locked so that it becomes something like a hot eyeball world: Set the planet at ...
