An electric fish generates an electric field using an electric organ, modified from muscles in its tail. The field is called weak if it is only enough to detect prey, and strong if it is powerful enough to stun or kill. The field may be in brief pulses, as in the elephantfishes, or a continuous wave, as in the knifefishes.
As almost all electric cars have regenerative braking brake pads can be used less frequently than in non-electric cars, and may thus sometimes produce less particulate pollution than brakes in non-electric cars. [9] [10] Also, some electric cars may have a combination of drum brakes and disc brakes, and drum brakes are known to cause less ...
President Biden has said there's "no turning back" on the transition to zero-emissions vehicles, but skeptics say hopes that electric cars will stave off climate change are overly optimistic.
Extreme E is an international off-road racing series with environmentalism at its forefront. The series sees drivers race the all electric SUV Spark Odyssey 21 in remote locations specifically chosen to highlight climate change, while adopting legacy projects that provide environmental and social support.

Electric organ discharges are two types, pulse and wave, and vary both by species and by function. Electric fish have evolved many specialised behaviours. The predatory African sharptooth catfish eavesdrops on its weakly electric mormyrid prey to locate it when hunting, driving the prey fish to develop electric signals that are harder to detect.
A group of climate change activists poured quarts of oil on the floor and on at least one electric vehicle at the opening day of the New York International Auto Show on Saturday morning.
For example, a horse can sniff the air to detect pheromones but a fish which is surrounded by water will need a different method to detect chemicals. Aquatic animals can communicate through various signal modalities including visual, auditory, tactile, chemical and electrical signals. Communication using any of these forms requires specialised ...
