One thing that has always bothered me in robot-controlled AI stories is that there is always the assumption that the AI would choose to fight a conflict against humans on Earth, where humans domina...
As we know, solar power is the ultimate source of energy for mankind, and it's the most abundant(I have read that we receive more than 1000 times the energy we currently use, if we were to have a w...
It is some small number of years into the future. We are regularly using beamed energy, as defined in this answer: large arrays of microwave transmitters. We have developed this so that these array...
A generation ship was sent out a long time ago, to colonize a far away planet. However the ship failed to reach its goal due to navigational issues (which also means they didn't have any clue where...
We all know the Kardashev Scale , and the energy output required to get to each level , but what would be the best way to transport those amounts of energy? I have come up with ways to distribute e...
A boundless AI brain could survive on any planet that has some basic metals and power sources, because it could invent new types of transistors from any kinds of chemicals to increase it's knowledg...
To avoid being too broad, I'd like to use the portals for purely altruistic purposes (health, environment, safety), and not for scientific or military acheivement (e.g. - not an instant space eleva...
So the idea is that the world has been destroyed, and an emergency plan to put the rest of humanity on floating cities/islands has been put in place. These islands subsist off of some sort of gener...
For this question I'm assuming a utterly infeasible technological breakthrough suddenly makes wormholes technology possible. However there is a major catch, the 2D "windows" as they're called don't...
Yesterday I was driving at night on an unlit road (nothing nefarious, I swear), and there was a truck behind me with a ridiculous amount of headlamps on, and catching a glimpse of it in my mirror i...
In a world where most grid electricity energy is from solar (with wind, hydro etc only supplying small amounts), you would need to balance out the load somehow. One idea I've had is to use "reverse...
I trust Brandon Sanderson to have done his research - in his book "The Rithmatist" he writes about coiled spring batteries that power a passenger train. I do wonder what could be achieved with a sp...
My Earth is similar to our real Earth, and some scientists have found out a really cheap way to use geothermal energy. Huge generators are built, but one scientist eventually found out that the Ear...
An x-ray binary is a binary star system consisting of a star and a stellar remnant. As matter is ripped from the star and is then accelerated into the neutron star/black hole by its gravity, x-ray...
A race of aliens exists on a distant planet whose biological functioning depends on absorbing a specific type of energy. They have what is essentially an antenna through which they passively absorb...
Is there an energy substance, element, material, natural or artificial resource with attributes such that: When its moved it loses energy. When its intact, untouched and unmoved it contains energy.
Can we harvest the fission energy inside of Earth and produce a energy beam powerful enough to destroy Near Earth Object such as an asteroid? Is this technology probable in the next couple of centu...
Often in science fiction, writers attribute the enormous energy capability of an advanced civilization to Dyson spheres. I've never heard of a detailed schematic of how the energy from the star is ...
Scenario Set in modern day Antarctica, a group of very talented scientists are working on a highly confidential scientific experiment which would one day allow us to manipulate time literally. The...
I've been hearing and reading about that solar flare in 2012 that could have sent us back to the 18th century, by causing huge geomagnetic storms which would have prevented (every?) electricity-bas...
In a type III civilization probably even type II, would have developed solid energy construct resembles force shield which acts like a semi-permeable membrane to allow friend to pass but prohibit s...
Since earthquakes, typhoons, tsunami and many natural disasters were measured or calculated to release more energy than many H-bombs can produce every seconds, can we one day harness this powerful ...
The scenario is that it is a post apocalyptic world where the most of the humans have been eradicated and the sources of energy have been completely depleted. In this scenario, people discover an a...
Scenario: Earth men colonized Alpha Centauri. Barnard's Star is at range. There is a huge fleet of fission bomb pulse propulsion cargo ships. Given Enough time and space they can reach 0.8C. Qu...
Fits into the planetary transfer of energy category...for whatever reason and using whatever means, one planet is used to generate a massive amount of energy, ultimately as electricity. This power...
How feasible would it be to use a huge electron gun to pump electrons from a solar array positioned close to the Sun back to Earth or Mars? My idea is to create a eletrical circuit by means of usi...
It is well known that some organisms can produce electricity. Therefore I think it would not be too much of a stretch to assume that also some plants might have evolved that ability (after all, it ...
Imagine that we live in a setting where there are a trillion humans (see linked question). A bit crowded, I know. Further imagine that at least the entire energy output of the Sun was available to ...
For the longest time growing up with Peak Oil and other such dire predictions, I assumed humanity had just about peaked, in terms of industrial-technological might and capacity to influence its env...
A Dyson Laser would be a spherical swarm megastructure arrangement of robots focusing mirrors directing sunlight towards a particular planet in a system heating it with enough energy to melt it. T...
Instead of trying to tether the Moon, can we somehow harness the Moon's kinetic energy, the same way we do wind? If so, how is this possible?
