Natural gas provides the only proven low-pollution alternative to diesel, the critics say.
You may consider significant differences in noise levels, radiant heat, or dissipated static electrical energy of pollution control alternatives.
Coal-fired power plants are a significant contributor to Australia's greenhouse gas pollution, but alternatives that rely less heavily on fossil fuels are growing.
A three-level hierarchical procedure is proposed for carrying out the identification of waste sources, the generation of pollution prevention alternatives and mathematical optimization.
Government policy and incentives could prod things along, especially given the new administration's ambitious designs to curb pollution, encourage alternative fuels and improve energy efficiency.
Thus, the influence of noise pollution of alternative airport sites on spotted seals (Phoca largha) was analysed by investigating the activity levels of spotted seals in engineering areas in this paper, and scientific results were obtained.
With ties to many other areas of science and engineering, MAE faculty also have a major impact in control and dynamical systems; materials science; satellite technology and propulsion; stability and control of vehicles; robotics; aircraft performance; pollution and alternative fuels; energy conversion and storage; nuclear security; biomechanics; and instrumentation.
We have long-standing interests in all manners of problems across Mechanical and Aerospace Science and Engineering: for example, in space exploration, satellite technology, pollution and alternative fuels, energy usage, battery technology, novel optical systems, propulsion systems, mechanics of fluids and solids, stability and control of vehicles, aircraft performance, and instrumentation.
I think the environmental movement should promote nakedness and idleness as a low-energy, pollution-free alternative to artificial cooling.
If driving your own vehicle is something you don't want to give up, consider saving up for an efficient, low-pollution electric alternative.
