港媒报道，中国通过研制综合电力推进系统解决了为采用常规动力的 002 型航母配备电磁弹射系统的重大难题， 002 型航母的研制和建造将驶入快车道。 海军推进技术的突破将使中国第二艘国产航空母舰在不装备核动力的情况下使用世界上最先进的弹射系统，这克服了舰船发展的巨大瓶颈。综合推进系统(IPS)的发展将使船舶效率更高，允许为电磁弹射器提供更多电力，从而不必使用技术含量较低的蒸汽弹射器。

Marine batteries form one of the main components of marine powerboats. Every powerboat requires power for a starter motor and fuel injector, which is supplied by the powerboat battery. The type of marine powerboat battery is determined based on the frequency of boat use and the number of electrical components present in the powerboat. Since boating activities are seasonal in nature, marine powerboat batteries are made to withstand long periods of inactivity unlike car and truck batteries that are used regularly. Periods of inactivity can cause batteries to discharge power, weakening their energy storing capacity. Deep-cycle batteries are largely preferred for powering marine engines as they store energy for longer periods of time without getting completely discharged when not in use. Deep-cycle batteries are able to discharge about 30% of their capacity without damaging the storage capacity.

Since the last decade, the introduction of new tourist destinations has fueled a revolution in the global tourism industry. With the increase in the number of the tourism service providers, there has been a significant growth in the demand for air travel and a simultaneous rise in the number of aircraft and helicopter. Some countries, such as Australia, France, Spain, South Africa, Hong Kong, Indonesia, the UK, and the US have been the major beneficiaries of global tourism over the years.

Sports bicycles are made to be fast and easy to handle on mountainous, rocky terrains as well as on smooth surfaces such as roads. Advanced technologies and high quality gears and brakes are used for sports bicycles, and wider tires than those used in road bicycles are used for mountain bikes. Apart from being used for sports activities, these bicycles can also be used for regular commuting. The global sports bicycle market is expected to grow steadily at a CAGR of 5.60% during 2016-2021.

Looking at the significant increase in global and regional air travel, the aerospace industry has introduced small airplanes (such as light and ultralight aircraft and motor gliders) for personal and business purposes. Such aircraft are also used in military operations and for freight carriage. Moreover, with the steady growth in the tourism industry and in the number of the tourism service providers, there has been a significant growth in the demand for air travel and a simultaneous rise in the number of light aircraft and helicopters.
