  • So... there will be no jobs unless you build or maintain robots?

  • @usmcboyer you may use robots to build robots. (reprap)

  • We need a better utilization of the INTER-NET. We could use it for approving intentions from the collective democracy, like an on-line congress of sorts.

  • Now those are the kinds of erections I wouldn't mind seeing!

  • what about solar flares if one hits chaos would arise that could easily destroy the society. 

  • @lauris15151 You can guard against solar flares. It's just a matter of keeping all electronic circuits wrapped in a faraday cage. I don't think it'd be that hard.

  • @Nathan173AB r u serious it would! Everything would have to be in faraday cages thats a bit crazy!

  • @lauris15151 Just wrap it in some bronze mesh or some metal foil. That's a faraday cage. Simple.

  • @Nathan173AB 1st the actual faraday cage cant touch the actual electronics or metal parts of the device so it can be practical. i heard something about military protected emp devices that has spare capacitors to store the surges but i am not sure about how it works tho...

  • @lauris15151 It can be done practically. So it can't touch the circuits of the device. So what? Just wrap an insulator between the device and the cage mesh.

  • @Nathan173AB i bet there is way better way how to do it without wasting presiaus materials...

  • @lauris15151 The materials you can use to make a faraday cage are actually quite abundant. Aluminum foil can be used and, aluminum does happen to be the most abundant metal in Earth's crust. But you might be right. Even though it is feasible, there might be simpler solutions

  • @Nathan173AB bauxite is really difficult to make into aluminum coz it requires a lot of energy to make aluminum. Aluminum isnt really abundant at all.

  • @lauris15151

    aluminium isn't abundant??? i would recomend you to search wikipedia in that regard

  • @levogiro aluminum cant be found in its natural form as a metal it is only abundant in other compounds so you wouldn't make a faraday cage out of potassium aluminum sulfate...why is aluminum so expensive these days? because its scarce!! thats why...you need to think!!!

  • @lauris15151

    yeah i know.... i wasn't arguing about in which form is found in nature... just that it IS in nature. Aluminium isn't expensive for its scarcity... it's expensive because to transform those compounds in which Al is found in nature... requires HUGE amounts of energy... and today, energy is quite expensive. You can use Al price as a thermometer of energy prices in fact. And that's because is produced by electrolysis.

  • @levogiro

    and for the same reason that it is energetically demanding to produce (it's a very electropositive, and therefore reactive metal... that's why it's not found in its native form on nature)... it has some of its technically useful properties... the fact that it easily oxidizes is which drives the phenomenon of self pasivation, and what makes it so durable (in contact with air it form a thin layer of very hard oxide wich block the access of oxigen to the rest of the mass of metal).

  • @levogiro i said this before, and it is impossible to find pure natural aluminum so aluminum is scares as a metal this is why it requires so much energy to extract not like iron ore etc.. , the thing is it doesn't mater if its scarce or not it need a lot of energy to extract from ore and that is a difficulty..

  • @lauris15151 I can concede the fact that a metal like gold, platinum, iridium or osmium is expensive on virtue of its low abundance, and that this factor is crucial in determining its value: to extract a given amount of one of such metal requires an extraordinary amount of social labor (which in the last term is which determines the value of a good (something conceptually different from the price of a product in the market)). But case is... having an inexpensive source of energy is equivalent

  • @lauris15151 to have inexpensive aluminium. Its abundance will become a secondary factor determining its value, because compounds of aluminium are ubiquitous in earths crust (being a light metal, it has tended to concentrate in the crust, as heavy metals has tended to concentrate below it).

    Regards!

    PD: Interesting discusion btw :)

  • @levogiro true, still aluminum is expensive product compared to other materials like plastic etc..and this is coz of the difficulty of extracting it from compounds, it can be the most abundant material but still it must be extracted and in this case it requires a lot of energy thats why its abundant but expensive, and thats why its not good metal to make faraday cage for every single electronic device on the face of the planet..

  • @lauris15151

    Totally agree in that. It's not the cheapest of metals. But that's the result of a set of market and technical conditions that can be regarded as an historical accident. As soon as a good energy source appears, aluminium would become cheaper. I really don't know if it's the best option for Faraday cages, should make a little research about that. But I guess that is a good compromise solution having in mind that is a pretty good conductor, and still a lot cheaper that copper.

    Hugs!

  • @levogiro  i think you should research on the ways of protecting the devise from EMP. because military has used these diode like chips that prevent the surges from damaging the electrical equipment, Putting every single piece of wire and electronic devices in Faraday cages is stupid and should not be done as its not efficient and so a lot of material would be wasted.

  • @lauris15151

    why so obsessed with Faraday's cages? o.O? In any case... those diodes you mention are mainly for protection from ESD (Electrostatic Discharge). And yes, its true that also reduces the susceptibility to damages due to EMP, nevertheless they doesn't make them totally immune. Only thing that make an electronic equipment REALLY immune to EMP is a Faraday cage, eliminating ALL field inside it, which could result from EXTERNAL FIELD.

  • @lauris15151

    ... anyway, in any case, Faraday cages in consumer products are not really to protect them from EMP. Sony really doesn't give a crap if your DVD is fried by a high atmosphere nuclear burst, but they care about FCC regulations, which dictate that the apparatuses they make have to comply with certain restrictions regarding electromagnetic emission, in order to avoid interference with other devices. That's the why of FCs in consumer products. A well designed chassis could make the job.

  • @levogiro what u r saying is totally wright, the thing is my first comment was what would if solar spots would cause electro magnetic pulses on earth and all electronics would fail who would fix it.

  • This is the future and hope many of you are open minded enough to see that. Contribute your ideas and please, no politics!

  • Imagine a world where everyone has the same social level, where we all can live at peace, the only way that we can become that ilussion in a reallity in no time, its by working together, by making a huge effort to change, first your ideas, and then the ideas of all people that surround you. Think about it, the future is in our hands, please make it a good future. Ps: excuse my poor english level, but try to understand the real meaning of this message

  • YES!! This is it!

  • 1:21 N E S?? Nintendo Entertainment System??
