  The Manta5 hydrofoil bike will allow you to race on the water at a speed of 20 km / h For the first time, the Manta5 hydrofoil water bike became known at the end of 2017. Its official presentation took place three years later, at the prestigious CES 2020 exhibition. The concept of this water-powered e-bike was developed in New Zealand. Production of one of the models – Manta5 XE-1 is established in China, it was presented last weekend at the Sanctuary Cove International Boat Show. A well-trained rider will be able to use the XE-1 pedal system to accelerate to 22 km / h and arrange an unforgettable 4.5-hour boat trip. The time is determined by the charge of the battery that powers the electric motor, which helps to turn the screw. You can already buy the Manta5 XE-1 in the US, UK, Europe and New Zealand at a price of $ 9,000. It is expected that by 2023, the company will produce several models of hydrofoil water bikes, including racing versions of the Manta5 XE-1 and a special mod...

The idea of robots, swarms of which can dig underground settlements on Mars, is proposed


A team of researchers from the Delft University of Technology has proposed a plan to build residential settlements in the depths of Mars. For excavations, scientists suggest using swarms of robots. Underground settlements, according to scientists, will protect people from micrometeorites, radiation and other potential hazards.


The settlement process will involve excavating the regolith and printing elements of the new habitat on a 3D printer. For the construction on Mars, the university's robotics laboratory chose the shape of a spiral going deep into the Earth. This design will be stable, safe and will take up a minimum of space.


The researchers have only prepared a demonstration of the technology so far; additional work and funding is required for the idea to become the concept of a real mission. The university believes that if successful, robot swarms and 3D-printed habitats will play a key role in the development of the concept of an underground city on Mars.
