39 results about "Effects of global warming" patented technology

The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases. There is a broad scientific consensus that climate change is occurring, and that human activities are the primary driver. Many impacts of climate change have already been observed, including extreme weather events, glacier retreat, changes in the timing of seasonal events (e.g., earlier flowering of plants), changes in agricultural productivity, sea level rise, and declines in Arctic sea ice extent.

This spark plug eliminates misfire and improves gas mileage, peaks engine performance, horsepower, and increases the RPM range, while utilizing and enhancing current ignition systems. In addition, this spark plug serves as a low emission device that reduces the effects of global warming, acid rain, and smog via greatly reduced emissions through vastly improved fuel combustion within all internal combustion engines by operating at a 24:1 air-to-fuel ratio. This unique spark plug is comprised of an elongated or non-elongated body with an electrical connector at one end. An absolute aerodynamic semispherical dome or sphere electrode is secured to the other end of the body. At least one absolute aerodynamic semicircular electrode is also secured to the body adjacent to the dome or sphere electrode such that the semicircular electrode has its inner surface equidistantly spaced from the dome or sphere electrode's surface. The electrodes can be fabricated from various metals, alloys, and / or precious metals and can also be coated with various metals, alloys, and / or precious metals. Alternate embodiments of the invention include two, three or four or more semicircular electrodes, all of which have a surface equidistantly spaced from the aerodynamic semispherical dome or sphere electrode along its complete arc length.
