Economia Bazata Pe Petrol Optiuni

[jet li]

Nu e nevoie ca petrolul sa se termine cu totul pentru ca un om sa nu-si mai permita sa faca un drum cu masina, fabricile de orice fel sa nu-si mai permita sa produca, si toata economia unei tari dezvoltate sa nu mai functioneze. Consumul depaseste deja productia, preturile vor continua sa creasca, iar resurse noi de petrol nu se mai gasesc, e mai scump pentru o companie petroliera sa caute resurse noi decat sa nu caute,asta pentru ca ce descopera va fi oricum putin
Ce solutii sunt la problema asta ?

Nu stiu daca trebuie sa ne impacientam in privinta asta. Sa nu uitam ca stiinta mai are asi in maneca. Un exemplu ar fi nanotehnologia, care e posibil sa deschida un nou capitol in istoria umanitatii. Pentru cine nu stie, nanotehnologia reprezinta manipularea a atom cu atom, pentru a se creea obiecte/masini/etc. de dimenisunea unor celule. Se spere ca in timp, sa poata fi produse si obiecte la scara macroscopica. E adevarat, pana acum nu s-au reusit cine stie ce, dar se aloca sume uriase cercetarilor, si pentru din ce in ce mai multi savanti este deja o certitudine faptul ca se va reusi si ca va insemna un pas mare pentru umanitate. Daca acest lucru se va intampla, s-ar putea sa nu mai avem nevoie nici de petrol, nici de carbuni sau lemne. Si toate astea ne-ar putea paste in prima jumatate a secolului.

Cele mai fanteziste scenarii sunt :

The first products made from nanomachines will be stronger fibers. Eventually, we will be able to replicate anything, including diamonds, water and food. Famine could be eradicated by machines that fabricate foods to feed the hungry.

In the computer industry, the ability to shrink the size of transistors on silicon microprocessors will soon reach its limits. Nanotechnology will be needed to create a new generation of computer components. Molecular computers could contain storage devices capable of storing trillions of bytes of information in a structure the size of a sugar cube

Nanotechnology may have its biggest impact on the medical industry. Patients will drink fluids containing nanorobots programmed to attack and reconstruct the molecular structure of cancer cells and viruses to make them harmless. There's even speculation that nanorobots could slow or reverse the aging process, and life expectancy could increase significantly. Nanorobots could also be programmed to perform delicate surgeries -- such nanosurgeons could work at a level a thousand times more precise than the sharpest scalpel

Nanotechnology has the potential to have a positive effect on the environment. For instance, airborne nanorobots could be programmed to rebuild the thinning ozone layer. Contaminants could be automatically removed from water sources, and oil spills could be cleaned up instantly. Manufacturing materials using the bottom-up method of nanotechnology also creates less pollution than conventional manufacturing processes. Our dependence on non-renewable resources would diminish with nanotechnology. Many resources could be constructed by nanomachines. Cutting down trees, mining coal or drilling for oil may no longer be necessary. Resources could simply be constructed by nanomachines

Sa fie nanotehnologia doar un vis frumos ?
