Electric boat
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators.
While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the energy crises of the 1970s, interest in electric boats has been increasing steadily, especially as more efficient solar cells have become available, for the first time making possible motorboats with a theoretically infinite cruise range like sailboats. The first practical solar boat was probably constructed in 1975 in England. The first electric sailboat to complete a round-the-world tour (including a transit of the Panama Canal) using only green technologies is EcoSailingProject.
One of the main benefit of shift to electric from fossil fuelled boats apart from environmental benefit is the low cost of operation. The spread between diesel and electric depends on fuel cost and grid cost in the respective region, but in a place like India this could be factor of ten.
An early electric boat was developed by the German inventor Moritz von Jacobi in 1839 in St Petersburg, Russia. It was a 24-foot (7.3 m) boat which carried 14 passengers at 3 miles per hour (4.8 km/h). It was successfully demonstrated to Emperor Nicholas I of Russia on the Neva River.
It took more than 30 years of battery and motor development before the electric boat became a practical proposition. This method of propulsion enjoyed something of a golden age from about 1880 to 1920, when gasoline-powered outboard motors became the dominant method. Gustave Trouvé, a French electrical engineer, patented a small electric motor in 1880. He initially suggested that the motor could power a set of paddle wheels to propel boats on the water, and later argued for the use of a propeller.
An Austrian émigré to Britain, Anthony Reckenzaun, was instrumental in the development of the first practical electric boats. While working as an engineer for the Electrical Power Storage Company, he undertook much original and pioneering work on various forms of electric traction. In 1882 he designed the first significant electric launch driven by storage batteries, and named the boat Electricity. The boat had a steel hull. It was about 26 feet (7.9 m) long, with a beam of about 5 feet (1.5 m) and a draught of about 2 feet (610 mm). It was fitted with a 22 inches (560 mm) diameter propeller. The batteries and electric equipment were hidden from view beneath the seating area, increasing the space available for the accommodation of passengers. The boats were used for leisure excursions up and down the River Thames and provided a very smooth, clean and quiet trip. The boat could run for six hours and operate at an average speed of 8 miles per hour.
Moritz Immisch established his company in 1882 in partnership with William Keppel, 7th Earl of Albemarle, specializing in the application of electric motors to transportation. The company employed Magnus Volk as a manager in the development of their electric launch department. After 12 months of experimental work starting in 1888 with a randan skiff, the firm commissioned the construction of hulls which they equipped with electrical apparatus. The world's first fleet of electric launches for hire, with a chain of electrical charging stations, was established along the River Thames in the 1880s. An 1893 pleasure map of the Thames shows eight "charging stations for electric launches" between Kew (Strand-on-the-Green) and Reading (Caversham). The company built its headquarters on the island called Platt's Eyot.
From 1889 until just before the First World War the boating season and regattas saw the silent electric boats plying their way up and downstream.
