Oil is found in relatively few places, and its energy density, pumpability and ease of use in internal-combustion engines makes it particularly well suited as a transportation fuel.
These devices, which work by combining hydrogen with oxygen from the air to produce electricity, are popular candidates to replace internal-combustion engines in road vehicles.
"We really and truly expect that fuel cells are going to double the fuel efficiency of the best internal combustion engines and in some cases triple it, " Roan said.
Methane can be used in any application we need done, including powering internal combustion engines -it can even be used in catalytic fuel cells.
Now, it's true that amazing gains are being made in the efficiency of internal combustion engines, both gas and diesel: direct injection, cylinder deactivation, stop-start, eco-mode throttle mapping, to name a few of the recent applied technologies.
Dr. Vladimir Kliatzkin, a scientist with more than 40 years of experience in energy production and accumulation systems for aviation, internal combustion engines and hybrid systems, originally developed the innovative wind-power technology and is currently commercializing various applications incorporating the technology through WinFlex.
Technologies such as internal combustion engines and gas turbines will continue to improve gradually in efficiency but they are familiar and developed.
High-efficiency internal combustion engines combined with lightweight materials can dramatically increase fuel efficiency in cars and trucks.
FORBES: Solar-Powered Cars? Clean Energy Hype Needs a Sober Dose Of Reality
With the loss of inefficient internal combustion engines along with the use of heat-pumps and better insulation in the building sector etc.
Instead, I leaned in farther in a panicked attempt to find the nearest sidewalk and escape the internal-combustion engines threatening to crush me from behind.
