Why? June 21, 2006 9:10 AM

I still wonder why energy efficient cars (hybrids) are not yet the dominant part of sales?  [ send green star]

You might be right May 09, 2006 12:26 AM

I guess it is a mix of all these reasons which hinder a faster development. We know well that even in conventional technology there is much better efficiency possible specifically by also building lighter cars and engines. Also consumers often do not accept easily new concepts - this also hinders them to become common good!  [ send green star]
 
Corrupt governments... April 26, 2006 5:42 AM

I feel that the environmentally-friendly technology will never be produced on a massive scale as our governments will never let the revenue-earning oil imports be cut off totally. In addition to the revenue earned from taxes, the government also collects revenue oil companies, so a major political revamp is necessary. Correct my facts if I'm wrong please, I'm only a 16 year-old student and not very well-read on the on-goings of the environmental movement.  [ send green star]  [ accepted]

Thanks for the invite.

Here is a little something I read the other day.

I always listen to coast to coast www.coasttocoastam.com on the xm and followed a link to this :

Researchers in Washington state are working on a generator that might replace internal combustion engines in hybrid electric vehicles. It would give these vehicles a much greater driving range than solar powered cars while nearly eliminating hydrocarbon and carbon monoxide emissions. And because the device operates at relatively low temperatures, it's not expected to produce oxides of nitrogen (NOx).

Developed at Western Washington University's Vehicle Research Institute and X Crystals of Issaquah, Wash., the patented device is a ten-inch-long generator dubbed the Midnight Sun. A burner inside the the generator ignites a mixture of air and natural gas, heating a ceramic tube to more than 1,400C; in effect, the tube becomes a tiny sun. Super-efficient but expensive gallium antimonide solar cells are arrayed around the glowing core to convert thermal energy into electricity that could power a car and charge its batteries. Because the natural-gas generator burns fuel continuously, carbon monoxide and hydrocarbon emissions would be one-fiftieth those of vehicles with internal-combustion engines.

The researchers have already built a prototype of the Midnight Sun that is powerful enough to operate a small television. The next step is to construct an eight-burner generator that will be installed in the university's Viking 23 vehicle. While the car could operate strictly on natural gas, it's intended to run primarily on battery power. The Midnight Sun generator is a backup system designed primarily for recharging the batteries and for long trips.

The generator will produce 20 kilowatts, giving the car the horsepower of an early Volkswagen Beetle. Running on the generator alone, the vehicle could maintain a speed of 60 mph on level ground, but it would need help from the batteries in order to climb hills at that pace.

The primary obstacle to commercialization is the expense of the gallium antimonide solar cells: They currently cost about $300 apiece, and hundreds are required for each of the eight burners in the Viking 23 car. The generator could soon be cost-effective enough to be used in cabins, motor homes, and boats, however. In these applications, the Midnight Sun would serve as a co-generator, providing electricity as well as space heating.--Dawn Stover

Thank you Francois January 05, 2006 7:50 PM

for the invitation.  I wish I could take public transportation to work but can't because of the nature of my job.  I am very hopeful that I can afford to buy a hybrid later this year.

Hello Francois, Thank you for the invite.

You know the USA doesn't want fuel efficient vehicles. That would mean that our greedy oil tycoons, including our president wouldn't be able to drain us of our hard earned dollar, which keeps them extremely rich. Don't mean to sound negative, but it is the truth.

Re-Activation on Demand!!! YAY! January 02, 2006 12:26 PM

This thread deserves reactivation... a subject well-worth discussion! My daughter is actively pursuing this topic... I will share with her at my next available opportunity, and let her know about this group! Thank you, Francois!  [ send green star]  [ accepted]
 
EFFICIENT CARS October 08, 2005 8:52 AM

Energy-save with "Pac Car II" --- The ETH Zurich Swiss hydrogen vehicle sets up world record The hydrogen vehicle "Pac Car II" sets up a world record for energy efficiency the 26-June-2005. The world record was performed on a round circuit in the French Ladoux With only 1,07 gram of hydrogen. If converted into a litre of gasoline it drove a 5384 kilometers distance. The 1-Liter-record is considerable even if it is based on the projection of the achievement during an one-hour travel. The 30 kilograms light car is equipped with a fuel - cell which gains electricity from transforming hydrogen into water and with it propels two electric motors. As only emission this vehicle produces pure water. With its low energy consumption the vehicle could drive once around the earth using just eight liters gasoline. http://dingo.care2.com/pictures/c2c/galleries/albums/3/315430781/Graphs_etc/Pac-Car%20II.jpg  [ send green star]
