Charging electric boats in minutes!

Many people like boats powered by electricity. But one of their main disadvantages is the battery charging time. Luckily, this shouldn't be a problem now. Right now, US engineers are on the cusp of a new technological discovery.

One of the main factors affecting charging time is the cable that connects the boat to the charging station. Charging time is limited by cable bandwidth. For faster charging of batteries, it is necessary that a larger current pass through the cable. But increasing the current also increases the amount of heat generated. This, in turn, makes the system more likely to overheat and increase the risk of fire.

Researchers at Purdue University in Indiana, USA, believe they have solved this problem with a new charging cable. In addition to increased bandwidth, the cable is equipped with a cooling system. 

The prototype cable is capable of carrying 4.6 times the amount of current than the fastest chargers. In this case, up to 24.22 kW of heat will be removed. Ultimately, the charging time will depend on the output power of the power supply and the charging cable. The charging rate will also be affected by the power input of the boat's battery. To charge in five minutes, all three components must be rated at 2,500 amps.

Marina in Spain and its vague future

Tomas Maestre Marina's license expires next year. The owners of the Puerto Tomas Maestre wharf in Murcia (Spain) fear that in 10 months, when their concession certificate expires on April 23, 2023, they will be out of work.

Marina Thomas Maestre continues to be the most important port on the entire coast after the cancellation of the Puerto Mayor project. Recall that Puerto Mayor began to build on the Mediterranean coast almost two decades ago.

However, the 50-year-old permit to moor ships in this area will expire in April 2023. Although the Ministry of Public Development has announced its intention to extend the concession, the Association of Mooring Rights Holders is concerned that time is running out and there is no official response from the authorities. 

The association wants the regional ministry to extend the current concession for another 20 years. Thomas Maestra currently employs 35 people and is home to a large number of hotels, as well as commercial and maritime businesses, which will either have to close or continue to operate without the required permit if the certificate is not renewed. If this happens, only three legally licensed marinas will remain in Murcia - Aguilas, Lo Pagan and Mazarron.

New dates for the Paris Boat Show

The Parisian boat show, Salon Nautic, recently announced a change to its originally announced dates. This year the exhibition will be held from 3 to 10 December 2022 and will last eight days instead of nine. Held annually in the Port of Versailles, the Paris Show is France's largest boat show. It is attended by 785 exhibitors and 1300 brands. About 170,000 people attended the show last year.  

So far, no further information about the reasons for the change has been reported. But the French Maritime Industries Federation announced that the French government is offering financial assistance to small and medium-sized companies after the pandemic to encourage their participation in French exhibitions and fairs.

The Paris Boat Show is one of 79 events included in the aid program. According to a press release, this assistance will be offered to small and medium-sized companies to cover 50% of the cost of renting exhibition space at the expense of the state. The corresponding registration fees will also be covered, but not more than 12,500 euros per exhibitor.
