Suppose we could move gloriously and quietly along in our own comfortable car compartment some 20 feet high between the trees, yet with no engine running, no fossil fuel use, no greenhouse gas emissions, and no need to watch the road (Fig. 1). Or, we could zip along in channels dug just below...

A solution to growing petroleum imports and continuing urban air-pollution problems is the use of clean-burning nonpetroleum fuels in motor vehicles. Methanol is widely viewed as the most attractive candidate for transportation fuel of the future. We examine how methanol gained this preeminent...

A generalized framework is presented for analyzing the relative attractiveness of biomass fuel production investments on a disaggregate level, using a systems approach to integrate sitespecific considerations. A model based on this approach may be used to site and size prospective biomass fuel...

Quality of and access to medical care are strongly related to the medical basket, the set of services covered under the national health insurance system. Various health systems offer institutional solutions to cover services that are not included in the basket in rare cases. In Israel, patients...

China is currently experiencing accelerated urbanization, with total urban population accounting for 52.6% of the country's total population in 2012. The next 10 years is foreseen to be characterized by the rural-to-urban migration of more than 300 million citizens. The consequent pressure on...

This paper addresses the policy challenges of adjusting established regulations to accommodate evolving and new technologies. We examine energy and emissions regulations for older petroleum powered vehicles and newer plug-in electric vehicles. Until now, vehicle regulations across the world have...

The use of biofuels can increase land competition, leading to global land use change (LUC). LUC poses risks such as increased greenhouse gas emissions and food prices. The magnitude of the risk is uncertain, but could be significant. Given these uncertainties and risks, we suggest that...

A survey of vehicle owners was conducted in New York State and California to explore the potential target market for methanol in the household sector. Data were colleted on revealed and reported premium gasoline purchase behavior and willingness to pay for cleaner fuels and more power. We found...
