Aceste link-uri fac parte din categoria optimiste si trebuie tratate ca atare.
Unele sunt serioase, altele pur şi simplu gogoriţe sau mai rău, scrise de nebuni.

All electric vehicles.  Most cars and light trucks worldwide could  be replaced over time with electric cars and trucks.  Lithium-ion  batteries are at the ragged edge of viabiity today, with a bit more  development work and good controller electronics, EV's could be quite  viable, with 300+ mile ranges and performance BETTER than any gas or  diesel engined car.

Cea mai interesantă variantă până în momentul de faţă, cu toate că multe din calcule sunt greşite. Vă rog să citiţi cu atenţie şi referinţele (pentru calcule) care se găsesc în partea de jos a documentului.  Deocamdată sunt doar speculaţii, dar de departe cele mai promiţătoare şi credibile speculaţii. DACĂ preţul poate fi scăzut cum e scris în articol până la 150-200$ pe tonă în loc de 5.000$ / tonă în prezent. Altfel discutăm de echivalentul barilului pe la 500-600 $.   Adică litrul de motorină pe la 300.000-350.000 lei. Un plin de 50 de litri 15.000.000 lei.  
Widescale Biodiesel Production from Algae
Bineînţeles calculele sunt greşite aşa cum puteţi constata  Algae as a biomass source. Condiţiile din laborator nu există în natură. Sau sunt valide pentru un preţ de minim 200$ / baril.

 

Iată cum se sfârşeşte o păcăleală.

Petrol în Canada. 180 miliarde barili. Nu, nu e vorba de petrol convenţional, adică ieftin. Deajuns pentru 6 ani la consumul actual. Destul de mult, dar poate fii extras? Dacă e să credem ce zice Exxon-Mobil e posibil pe la 60$/baril.

Linkul ăsta n-am ştiut unde să-l pun: La optimiste sau pesimiste.
Dresselhaus was chair of a Department of Energy (DOE) panel that issued a 2003 report that found hydrogen fuel cells cost ten times more than gasoline engines. "We know how to make the fuel cell work," Dresselhaus explains. "The problem is to do it at a cost that's reasonable so a consumer would have some interest in buying a vehicle. And right now the cost of hydrogen fuel is a hundred times greater than what the Department of Energy has set as the proper, desirable level for fuel cell operation.
Şi continuă în acelaşi stil: Avem probleme mari, gigantice chiar, dar se vor rezolva. Nu ştim cum, dar aruncăm pisica moartă în curtea nanotehnologiei. Şi concluzionează optimist:
Still, road-tripping in your economy-priced hydrogen car is years away; hydrogen cars are being road tested, but probably won't be affordable for most drivers for at least ten years.

Pig Manure Eyed as Energy
URBANA, Ill. (AP)--A University of Illinois research team is working on turning pig manure into a form of crude oil that could be refined to heat homes or generate electricity. Years of research and fine-tuning are ahead before the idea could be commercially viable, but results so far indicate there might be big benefits for farmers and consumers, lead researcher Yanhui Zhang said.

The two-year experimental project is intended to collect data on biomass feasibility with an eye towards making the energy source efficient and affordable.
Shasta Energy Group is one of the groups involved in the demonstration project.
"A 50 kW gasification unit connected to the grid will be the first of its kind," said Thomas Deerfield, Shasta Energy Group's Biomax 50 project manager. "Part of the project is to smooth out the process of connecting biomass electricity to the grid."

Whacoooo

  For this purpose, may I recomend sodium borohydride as a carrier for
hydrogen.  Fuelcell-electric tractors and trucks are perfectly
feasible with a bit more development, and sodium borohydride/water
solutions are about one quarter as energy dense as gasoline.  Coupled
with the higher efficiencies of fuel-cell electric drivetrains, it is
pretty close to a direct replacement for gasoline/diesel, with the
advantage that the mixture is essentially non-flammable without a
catalyst present. http://gcep.stanford.edu/pdfs/hydrogen_workshop/Wu.pdf

It's specifically about Conoco's process, which the company is apparently pushing agressively.  There are a couple of charts on the page about Conoco's process that show $ / bbl ($23) and process efficiency in bbl / MMCF (122).  I think that's bbl of diesel fuel, since that's what the process is optimized for.  Not sure what that translates to, in terms of energy content of feed vs. product, or whether it accounts for external energy in to the process.

 

http://www.lbl.gov/Science-Articles/Archive/MSD-perfect-solar-cell.html Researchers in Berkeley Lab's Materials Sciences Division (MSD), working with crystal-growing teams at Cornell University and Japan's Ritsumeikan University, have learned that the bandgap of the semiconductor indium nitride is not 2 electron volts (2 eV) as previously thought, but is close to 0.7 eV.
