| | DailyTech - BMW to Unveil Hydrogen 7, Decline BLUETEC Diesels at LA Auto Show (Site not responding. Last check: ) |
 | | The control system in BMW Hydrogen 7 gives priority to the use of hydrogen; and should one of the two types of fuel be fully consumed, the system will automatically switch over to the other type of fuel. |
 | | By using hydrogen produced from water and renewable energy, such as wind, sun or hydropower, in an internal combustion engine, the car's emissions in hydrogen mode are essentially nothing but vapor, allowing the water cycle to start again. |
 | | The advantage of hydrogen over electric is that you can use both on the same engine, and don't need to carry heavy batteries around (and remember that lithium batteries will die after about 4 years, and are very expensive to replace, not to mention hard to recycle). |
