quantum dots are just nano crystals. some of the possible advances could arise in photovoltaics(solar panels), Light Emitting Diodes.. i think some research is being done on quantum dot displays for electronics. as for their use in solar panels, applying Q-dots allows for a wider spectrum of light to be absorbed by the panel, which would increase its output and efficiency. maybe also used in the newly researched optical transistors.. wonderful technologies. you should try to keep up to date with the lasted if your an electrical engineering student because technology advances exponentially. good luck in your studies

heres a nice presentation on them.

Q-dots are great for research. i have tons of journals and research papers on them.. dig deep.

i am not an expert in magnetohydrodynamics but it seems like either there is a very complex arrangement of super weak magnets underneath that ferrofluid( because simple magnetic field shapes change the ferrofluid shape in a different distinct, recognizable way http://en.wikipedia.org/wiki/Ferrofluid#mediaviewer/File:Ferrofluid_Magnet_under_glass_edit.jpg) or it is a combination of a weak magnetic field and the surface tension of the fluid itself creating this effect. this would be an interesting thing to figure out on a computer simulation program.

you could have a modular design and send out sections of the "planet" rather than building and sending out the whole thing at once. you could have many expandable, interconnected pods that will eventually form the larger whole.

after the foundation was built, then a larger infrastructure could be assembled. other modules could be sent with "self sustained" biosphere or a small version like that of the aquaponics system http://theaquaponicsource.com/what-is-aquaponics/

this system could be used for CO2 filtering, food, and fuel for the "planet" to run on. (rocket engines and generators)

other modules could later be sent up with communications and computer systems, and others.

personally i think it would be better to build a structure like this on a small moon or large astroid then it could be transformed into navigable "planet."

the population count would still be small, but larger than the 3 or 4 of the ISS

Algae grows faster than anything else, and it will grow in salt and soda water. It can be pressed into pellets, and used to fire a power plant. However, wind and PV solar should be used with algae pellets to take up the slack when wend and PV do not provide power. Also, liquid metal batteries can be made large enough to store energy from wind and solar to help with transients as generation changes from wind and/or PV to pellet fired power plants.

I agree with this. If a well balanced system is designed, similar to an aquaponics system, you can get a stable and more diverse output with algae like electricity, livestock feed, bioplastics, fertilizer for land restoration, etc..

One could use local sources of initial nutrition for the algae, similar to the fish waste fertilizing the vegetation in an aquaponics system.

The algae will massively multiply, then will be harvested, dried, and pressed for the extraction of biodiesel to run a generators. and the waste byproduct which is the algae remains could be either used as feedstock, fertilizer, or can be used for a biomass burning plant to generate more energy.

wasn't too sure where to post this, I thought engineering complimented it best.

 

If we were to sustain life on a vessel in space, what would be the most practical method to feed ourselves? I would assume livestock be out of the picture. With resources at much less availability than on a celestial body and ventilation not as free as a biosphere, what would be the most practical method? Corn, roots, moss, maybe even chemically synthetic minerals? What would be the most efficient way to feed ourselves in space? Growing crops and harvesting them? Livestock?

 

 

how about micro propagation? growing various vegetation in vitro. growing plants in this manner results in a faster growth rate, which is pretty important in space. you do not want to wait 4 months for strawberries to grow, when the same strawberries can grow from explant samples to fully hardened plantlets in just 3 weeks.

oh the virtual reality goggles?

They seem entertaining. Maybe a bit nauseating after a while haha i can only assume.

i think the Obama Care RFID controversy is a perfect example of memetics forming, evolving, and then delivering to everyone an idea that strings the cords of society, because society helps for it haha

oh im sorry i didnt elaborate a bit. i was just pointing out the advancements in the technology. just implying that this could potentially be used in implantable technologies like for example TV or visual data being stream directly into the brain. \

as for finding it scary, could you explain a little more? i get your take on orwellianism, but it that the only thing you are scared of in this technology? (or in technology in general for that matter?)

yeah thats what i was thinking. brain to machine interfaces are advancing very quickly

these scientist were able to reconstruct neuronal activities in the visual cortex into viewable images on a computer screen.

Yup I can do this.

This http://nationalreport.net/rfid-chip-now-being-issued-in-hanna-wyoming-as-part-of-new-obamacare-plan/ is scary

im not really getting the opinions. just links to other peoples opinions. lets take it back to basics shall we?

"On the occasion of every act ask yourself, how is this with respects to me?"- Aurelius.

why should i fear this technology? (it seems that is what you are implying)

and why do i care?(i ask with the most respect)

orwellianism can be seen in todays technologies.

 

Can these behaviors be seen with todays technologies?

you should have started protesting once the mobile cellular phone first entered the world because the provider of the services knows who, when, and where it is being using.

its called cellular geolocation.

by the way, that 1984 is my all time favorite book haha

hello all,

I'm new to the forum world. I wanted to start off with this topic of implantable CONSUMER electronics (not medical).

i feel like there would be lots of controversy similar to the whole RFID scare of obama care.

1) what are the ethical implications? (i have a very practical and technical sense of perception so i cannot think to deep when it comes to ethics of the technology. i would really appreciate outside opinions haha)

2)From an objective point of view, how would the "assimilated" human with enhanced capabilities (ex: seamless access to data, fully integrated health system-implanted medical diagnostics., enhanced perceptions, etc.) change society or human behavior? can these behaviors be seen with todays technologies?

who here would actually do it? (if pain and money were not obstacles ?)

3)what are some technical challenges and possible remedies for them?

4) features anyone? haha
