US Fleet

At 25 mpg, an original Model T would still give you better fuel economy that most vehicles...

Gizmag is always on the lookout for alternative means of powering vehicles and saving precious fossil fuels. But, in truth, the vast majority of us still drive exclusively petrol-powered cars. And the even sadder truth, outlined in a new research from the University of Michigan, is that the average fuel efficiency of a US vehicle has improved only three miles per gallon since the days of the Ford Model T.  Read More

Planning ahead: US electricity generation sources

While the current Wall Street financial crisis has many on edge in regard to the short term future of the economy, Google has displayed some far-sighted corporate leadership in releasing its plan for how to reduce fossil fuel use by 2030. "Clean Energy 2030" is designed to stimulate debate on a range of energy consumption issues and includes proposals to slash vehicle oil consumption and CO2 emissions by 38% and reduce US reliance on fossil fuel-based electricity generation by 88% through a significant boost to solar, wind and geothermal output. Importantly, the report also focusses on the "win-win" potential for this aggressive attack on climate change, citing a figure of $1.0 trillion net savings over the 22-year life of the plan.  Read More

Launched in Florida last week, the company’s flagship tyre inflation solution, the PurigeN98, uses 98% nitrogen to inflate tyres instead of air (78% nitrogen, 20% oxygen), and the basic idea is that if everyone used nitrogen instead of air in their car tyres, the world would be a cleaner, better place, with less petrol, oil and tyre consumption and hence less pollution. That’s true and the more we looked into it, the more using nitrogen makes sense. But will it save anybody any money?  Read More
