What is the Narcis monturiol medal?
BSE Director Teresa Garcia-Milà (UPF and BSE) has been awarded the Narcís Monturiol Medal by the Generalitat de Catalunya. The medals recognize outstanding achievements of individuals contributing to scientific and technological progress in Catalonia.
What was the first submarine ever built?
The first practical submarine was built in 1620 by Cornelis Drebbel under the employ of King James I. A leather-covered 12-oar rowboat, Drebbel’s submarine was reinforced with iron to withstand water pressure, and was functional, submerged to a depth of fifteen feet beneath the River Thames.
Did Spain invent the submarine?
Isaac Peral y Caballero (1 June 1851, in Cartagena – 22 May 1895, in Berlin), was a Spanish engineer, naval officer and designer of the Peral Submarine. He joined the Spanish navy in 1866, and developed the first electric-powered submarine which was launched in 1888.
How deep could the first submarines go?
It successfully navigated at depths of 12 to 15 feet below the surface and stayed submerged for three hours, traveling from Westminster to Greenwich and back. Legend has it that Drebbel even took James in this submarine on a test dive which would have made him the first monarch to travel underwater.
How did old submarines get oxygen?
How Did Early Submarines Get Oxygen? By using saltpeter, peroxide, or liquid oxygen for chemical reactions, WWII era submarined relied on a plethora of old-world systems and processes. Submarines also incorporated air exchange systems as a means to store and transfer liquid oxygen.
How do they get oxygen in submarines?
Oxygen onboard a submarine is released either through compressed tanks, an oxygen generator, or by some form of an ‘oxygen canister’ that works by electrolysis. Oxygen is either periodically released throughout the day at specific time intervals or whenever the computerized system detects a reduction in oxygen levels.
Who invented the first submarine?

When was the first electric submarine?
Peral was the first successful full electric battery-powered submarine, built by the Spanish engineer and sailor Isaac Peral for the Spanish Navy, in Arsenal de la Carraca (Navantia now). The first fully capable military submarine, she was launched 8 September 1888.
Do submarines have WIFI?
To connect with terrestrial technologies, the nodes communicate with gateway buoys on the water’s surface, linking to the above-sea internet via cellular networks or satellites. Still, undersea broadband is a way off, due to the low data rates.
What is the temperature inside a submarine?
around 30-35 degrees
Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.
Why do submarines get hot?
The metal of the submarine conducts internal heat to the surrounding water. So, submarines must be electrically heated to maintain a comfortable temperature for the crew. The electrical power for the heaters comes from the nuclear reactor, diesel engine, or batteries (emergency).
