science 2 - empowering technologies
should we find ways to use technology to spread out different kinds of social burdens,
from when people commute to work to when they eat their meals?
eg: the rise of online streaming services such as Netflix and BBC iPlayer have meant that the nation won’t simultaneously get out of their sofas to put a kettle on the stove
technology can fragment social experiences and it may soon cause some concern.
applications can help make sure we stick to those clocks more (i.e a meal scheduling app or a reminder to start commuting), but they won’t change it instantly or on such a wide scale.
autonomously powered batteries (ones that work off changes in the temperature or even ambient radio signals).
“British” plug look different than a “European” plug—where did these differences originate, and does it mean the electricity behind them is different, too?
learn the difference between alternating and direct current, and between adapters and converters.
future of batteries,
IoT - internet of things -
battery technology, which uses freeze-dried bacteria.
Does the calculation change if the creatures are dead? - excellent argument that we’re using their remains to benefit the rest of intelligent life
Would it be different if the bacteria were horses, or tardigrades?
is it acceptable to use living creatures to generate electricity, or is this a form of exploitation?
making the battery as small and as safe as possible.
One company called Ionic Materials (how fitting) is experimenting with an
ionically-conductive plastic that is also fire-retardant
(finally a solution to those nasty explosions of phone batteries on planes
Another solution for safety lies in the electrolyte, which some are beginning to test for the best materials. ).
One such solution lies in Silicon as a substitute material for the anode. According to Sila Nanotechnologies, “an atom of silicon can store 20 times more lithium can atoms of carbon”.
how would better power sources affect our everyday lives?
or would they have impacts on access to technology for, say, underprivileged populations?
make our phones last longer between charges??
something to fear?
Is it ever safe to depend on a technology that can sometimes be dangerous? eg: exploding batteries
We can never expect a product to be released with no safety hazards whatsoever, granted there are processes to ensure that products launch with as little safety hazards as possible; but even those cannot guarantee a product is free of danger.
We have always depended on dangerous technologies and we see no problem in doing so.
where to go after wireless charging.??
we may soon live in world without cables, reliant on all sorts of wireless devices that may one day fail us.
wireless charging utilises electromagnetic induction. This process means that when the back of the phone touches the charger, an induction coil creates an alternating electromagnetic field, which the receiver coil in the phone converts into electricity to feed into the battery.
anode | cathode | electrolyte | capacity | discharge
Innovation and danger walk hand in hand together, we simply need to find a way to separate the two.
the ethical side ?? when we’ve been exploiting animals for their power for centuries.
