Science Future: Portable Power


Science fiction inspires the world around us. It inspires our future. To discover these influences, we look to the future of science, to Science Future. The Science Future series presents the bleeding edge of scientific discovery and links it back to science fiction in order to discuss these influences and speculate on the future of science fiction.

Portable Power

Mobile and ubiquitous computing is one of the hot spots of commercial research and it has been slowly invading our science fiction for years. Almost every one can refer to at least one person, if not themselves, who carries the internet around in their pocket and nearly every space faring race seems to have easy access to huge databases of information just by saying or thinking the word “Computer”.  Today, most lunch-break trivia arguments can be settled, if not very quickly, before the bill has arrived. That is until the battery runs out. Even to the most casual user of digital devices, occasionally having to disconnect ourselves from our external memory and constant updates, to let our little glowing boxes recharge, causes anguish.

Batteries by Tomblois (CC BY-NC-SA 2.0)What would help alleviate this pain and suffering? Maybe if it didn’t take so long to recharge a battery. Researchers at the University of Illinois at Urbana-Champaign have found a way to use nanomaterials to recreate battery cathodes at a nano-scale that can charge up to 100 times faster than current commercial batteries but still power your netbook just fine. It helps explain why we never really see our protagonists pulling out their hyperspace coms and cursing that they forgot to leave it on the charger over night.

You still need to get power from somewhere, however, and some scientists at MIT have delved into biotechnology and developed an artificial leaf that will absorb a gallon of water and bright sunlight and produce enough electricity to power a house in a developing country for an entire day. The leaf works by simulating a form of photosynthesis, where in it breaks down water into hydrogen and oxygen and then uses those two elements to produce electricity. Imagine spaceships sailing through the solar system covered in artificial leaves that not only power our ships but also camouflage them in case they fly through a space forest.

If you’re not big into the flora fashion, Doctors at GeorgeTech have created one of the first commercially viable nanogenerators. That is to say they’ve created a flexible chip about the a quarter of the size of a stamp that generates electricity through simple movement. It does this by taking advantage of a nanowire property known as piezoelectric, or the ability to generate electrical fields when mechanically strained. Research suggests that five of these chips can output the same amount of power as a AA battery. Combined with the batteries above, this means that joggers and outdoor enthusiasts never have to worry about being disconnected from the internet ever again! Not a lot science fiction authors saw that one coming.

So does this mean that the lack of plugs, chargers, and batteries in our science fiction has been author oversight or author foresight? Science fiction likes it technological gadgets from laser rifles to portable shield generators to omni-tools but rarely do we see a person of the future angry over forgetting to charge their light sword. Ubiquitous energy seems to be the theme of the future and it’s fiction. But the issue of power has many reprocussions. Science is bringing us a future of full of miniaturized safe energy to help power our increasingly mobile lifestyles in a decreasingly large world. This might lead to stories that focus on the dehumanization, re-humanization, or even digitalization of human society. Either way power will always be an important part of science fiction even if most of science fiction chooses to ignore it.
