Gas & Oil problems – we are facing the same problems today as we did in 1973, and we had the same answers then

Tuesday, March 9th, 2010

…So in 1973, we said we should get off dependency to foreign oil and drill in our own land. We said we needed more technology like battery cars, hydrogen and ethenol, nuclear, wind, solar, yet today we are still facing the same old problem with the same old solutions. Eventually, back in 1973, we [...]

what is the best alternative to substitute petroleum without big effort to modify current machines?

Wednesday, December 9th, 2009

Most of current machine need petroleum for energy resource but the petroleum deposit currently becoming smaller from day to day. Many new alternative energy is prepared to replace it such as ethanol, hydrogen, etc. But to replace or modify current machines to fit with those new energy will cost much.

How are we going to live when we run out of petroleum?

Monday, August 17th, 2009

Given that the petroleum is finish, probably in 20 years and that there seams not to be an affordable and realistic alternative for it (sorry for those who have blind fate in science: neither biofuels or hydrogen will save us). What do you believe that ours live will look like when air and car transportation [...]

What is the efficiency of refining petroleum?

Friday, August 7th, 2009

Please show references or proof of your claim. I am looking a percentage of usable energy after refining over total energy before refining.
You know, analogous to the ‘refining’ efficiency of hydrogen from water, 80-94% (6-20% loss due to inefficiencies, heat, etc.).
PLEASE READ
I’ve asked this question twice and have not gotten an answer.
I do not [...]
