Weave a mesh basket like a tea infuser out of channelium with a long chain or wire handle. Put the stone inside the channelium basket. Use the handle to lower and raise the stone into and out of w...
Thermal convection is your friend By heating air in the center you can draw air down from the sides. Because of thermal stacking, thermal power generation towers can be as tall as 1000 meters.
So as others have said, air is a poor conductor of electricity compared to water, and so you would need unrealistic levels of electricity to make this work. Most super powers are essentially magic...
Late answer, but another possibility... The kind of spud guns I've seen around here didn't use compressed air, but instead used a flammable liquid/gas like alcolhol or aerosol hairspray to propel t...
What you're looking for is parthenogenesis. Scientists from Japan have done it with mice, back in 2004 by changing one egg to behave like a sperm cell genetically. With enough genetic engineering ...
Yes they do! We are really close to having this using femtosecond lasers. One cool thing about these projections is that you can actually feel them. Who knows, in a century it could turn into so...
It could be a matter of resources. Missiles are expensive, flak is cheap, and has the added bonus of deflecting lasers. So if one ship can surprise another ship then a missile might take it out, bu...
Your planet could be really low on iron. There is a tree condition called chlorosis that is caused by low iron in the soil, and leads to light green/yellow leaves. It could also be that the PH i...
One effect could be the illusion that the craft is moving backward, as the light from the vehicle being close to you reaches you before the light of the vehicle being further away. This would only ...
This is an addition to Willk's answer; Giant pupils would be a very good start, with the addition that the iris would have to be able to get the pupil small enough to allow function in the dayligh...
The dragons are ruminants with multi-part stomachs. They eat organic material, and in their first stomach burn the material at 800C until it become graphene oxide. In the second stomach the graphe...
Make them sweaty. Bit of background: SpaceX is redesigning their Starship Super Heavy (aka BFR) to be made from stainless steel, and plan to have it sweat as a heat shield. The basic concept is th...
Like sharks replace teeth. The plates can be put on the armor in an overlapping scale pattern, with one plate visible, and another above it, protected by the overlapping scale. If a scale takes a h...
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
So a bit of study has already gone into answering this question. To blow up a planet into tiny rubble Death star style, it would take 2,000,000,000,000,000,000,000,000,000 joules of energy. The ent...
This would not naturally work the way that you describe. Saturn has rings because the ice and rocks that make it orbit the mass of the planet. Without that mass, say if Saturn were to fall into a ...
There are a few things that you'd need to be able to clone a creature. One thing is a sample of intact DNA. If stem cells can be acquired to get it this would be better, as mature cells are specia...
The holes could work similar to a hole tone whistle, which is the principle used for a whistling tea pot. The basic idea is that a stream of air is directed through one hole, and a short distanc...
Going a bit more out there, say the aliens have discovered undeniable proof that the simulation theory is actually true. And they have figured out how to get access to some of the API from inside ...
My first thought was that the saying that we're "99.999% empty space" would easily solve this problem. The atoms would just push each other around a bit, and the parts that intersected the wall wou...
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...
