Erectile issue impacts men of all races, and there is with more energetic men starting now having ED. Aging is no longer directly associated with the onset of erectile dysfunction as believed by many. The sexual disorder is in actuality giving a huge impact in a man’s life, and being able to lose manhood untimely is amazingly troublesome and debilitating. To overcome ED problems and help men find their solution to improving their manhood, scientists have developed drugs that will make the lives of ED patients more manageable.
Vardenafil HCl is basically the generic version of the brand Levitra, thus it is sometimes called generic Levitra. Vardenafil HCl is a drug whose mode of action is to allow men with sexual impotence to get a momentary erection so they will be able to have successful sex with their partners. Medical professional consider vardenafil HCl to be safer than the popular ED drug Viagra because you will less likely encounter any visual changes while one vardenafil HCl. In fact, vardenafil is very safe that it can even be used by people with conditions or diseases like diabetes, prostate cancer, hypertension, liver and kidney diseases, multiple sclerosis, and Parkinson’s disease. Despite this, it cannot be said that vardenafil HCl is not without any side effects. Read more…
Hydrogen Buses in London
London is adding ten hydrogen powered buses to its fleet. Mayor Ken Livingstone has contracted US manufacturer ISE Corp to supply the new vehicles, and cites reducing pollution and greenhouse gas emissions as the primary impetus.
"London is now the first city in Europe to commit to a hydrogen bus fleet of this size, which will match traditional diesel buses in terms of performance," Livingstone said.
For £10 million ($20.75 million), London will receive five buses which run on hydrogen fuel cells and another five which burn hydrogen in a traditional engine. These will supplement the existing fleet of 8,000, many of which are diesel hybrids. The mayor’s target is “to have five per cent of all public sector fleet vehicles powered by hydrogen by 2015."
These buses are about eight times more expensive than traditional diesel buses. Mike Weston, Operations Director for London Buses, says that because the hydrogen buses produce no emissions beyond water vapor, they’re worth the extra cost.
While we at Carectomy think that public transportation in general is the bee’s knees, are jealous as hell of the systems in place in European cities, and recognize that alternative fuels can make mass transit an even deeper shade of green, there are some holes and perhaps some greenwashing in London’s bus project. Hydrogen fuel is not currently even close to “zero emissions.” Although the actual vehicle may only be emitting water, how dirty is the power source that separated the hydrogen to begin with (a very energy intensive process)?
Down the road, hydrogen tech may be a wonderfully green endeavor, and perhaps London’s financial support will help that mission along.
