H2O

Guys where could i find some tutorial about PICs. Im really into robotics. I need help. Another thing how would I enter MIT? hehehehe.:-)just a follow up question....

Yes the only solution of global warming is planting more young trees. I just want to help the cause thats all. :-D tnx guys.

Calcium sources are abundant in the earth's crust. you could find calcium compounds that are not carbonate based. You could have calcium silicate compounds. use calcium in the process while using silicon in computers.

can anyone help me how to build your own gyrocopter? anything any form any ideas:D

I need some explanation of how it works.....

But u see u can produce Ca(OH)2 by double displacement. they are all ions Ca2+ and OH-. A compound like MgOH or even CuOH could react to CaCl or any combination to produce Ca2+. Ca2+ is the one needed for the transformation. u just need to find Ca2+ in aqueos solution beacause you need the water too. Not all Ca2+ is found in the form of CaOH u know. So no worry to transform CaCO3 to lime stone. My calcium source is diff. i did not get my calcium from burning of chalk(CaCO3).

tetra my source of calcium is CaOH in aqeous solution!!!

half-equation is used in electrochemistry to balance oxidation and reduction reactions.

my friend and I think of a way of teleporting objects in space. This is only possible if strings exist. our idea takes us to build a machine that could determine specific string/blue print of a specific object. then breakdown matter into elementary particles. load them to a laser project them into space with the information of the string. then rebuilds the matter in the place desired. the string answers the problem of putting back matter to its original form. but how much energy is needed? is it even possible? :embarass:

Tetrahedrite--------"That's all well and good, you can use Ca2+ to remove carbonate from water and therefore CO2 from the air. But you have an enormous problem, where do you get the Ca2+ from? Nearly all the easily processable calcium used in industry is obtained from limestone. To obtain the Ca2+ from the limestone you need to release CO2, and thus you're back where you started."------ ---------"Calcium carbonate minus carbon dioxide is either calcium oxide or lime water - where do you take them from?" Borek----------- i think you have an idea of how i transform CO2 to calcium carbonate. the question is the source of your calcium. double displacements could create CaOH in the labaratory. and the rest is highschool chemistry. ps. u just need all the calcium in the world w/ a catch do not produce CaO or CaOH if ur by product is CO2 it just destroy the cause. After that the calcium carbonate is collected. And its all up to u to find some uses for that. Maybe bury them or build a your own pyramid. Well pyramids in egypt are built with limestone u know.

Boss new comer to the site i think as abundant water as it is, fusion reactors are not free energy because the process of harnessing water into a heavy one needs energy too you know.

hello everybody i discovered by myself the process of transforming carbon dioxide into calcium carbonate. and i think this is the solution for problems concerning CO2 emissions in factories. i tested the process and luckily it works!(science project in highschool). Plz rep if you need more info.

i am also baffled by string theory/idea and have questions on my own but i think it was developed by scientist to combine the quantum(small) and relativistic(einstein's,big oh very big) to what they call a "unified theory of the universe". p.s. i dont have enough idea of string theory itself by concept what really string theory is?

liquid helium exhibits 0 viscosity. they are superfluids and I think they are in the form of condensates--maybe bose-einstein condensates

What is String theory? plz. reply:rolleyes:

I think gravity comes from aliens in outer space!!!! hahahahaha!! just joking!! gravity is mainly the attraction of two masses. either small or big. I believe that an object with mass while with respect to the distance between them has gravity. gravitational forces are basic entities of matter along with the nuclear forces and weak, strong forces that govern matter in our universe. basically matter can be derived through energy and i think the energy maybe the reason of the existence of gravity. Example light is a form of a wave--a stream of enegy--but Albert predicted that light could be bent by gravity. I believe that light is no mass but pure energy but exhibits that of a "massly" object. energy could be the reason that gravity exist. ps. im not that intelligent as a scientist, maybe its a misconception but i think there is a slim chance that it could be true.
