2022-08-28 06:00:03 The SkyRide is a pedal-powered aerial ride.

This very ride is capable of transporting a person along an 800-foot route. All while controlling its own speed. The speed is controlled by hand brakes, just like a bicycle.

The SkyRide system is currently only designed for aft decks, or more simply, spa decks. Engineers are already developing this creation to move around the mountains.

2022-08-27 11:26:42 Passenger transportation on hydrogen trains started in Germany

Hydrogen trains emit only steam and condensed water and can travel about 1000 km without refueling, each can run on one tank of hydrogen all day. New locomotives are capable of driving the train at speeds of up to 140 km/h. Refueling will be carried out at a special station, which has 64 high pressure tanks (up to 500 bar), six compressors and two fuel pumps. In the future, it is planned to produce hydrogen here "on site" using electrolysis and "green" electricity.

Five trains are already operating on the route, the rest will be added to the fleet at the end of 2022, all of which will replace the diesel variants operating on the transportation network. This will save about 1.6 million liters of diesel fuel and avoid 4,400 tons of carbon dioxide emissions annually.

2022-08-27 06:00:04 Europe plans to get solar power from space - it will be expensive, but very clean

The European Space Agency (ESA) is going to ask for funding for a project of space-based solar power plant.

There are already programs to create space-based solar power plant projects in the U.S., China and Great Britain. Solar power stations on Earth's orbit will always be illuminated by the sun and can continuously produce electricity in an optimal mode. The energy can be transmitted to Earth both by laser beam and in the form of high-frequency radio emission. The European SBSP project will be called Solaris.

According to Frazer-Nash, the European space solar power plant may cost from €149 to €262 billion from 2022 to 2070. The main benefits will come from reduced carbon dioxide emissions and lower operating costs for power plants on Earth.

2022-08-26 14:02:00 American company Ryse Aerotech unveiled the Recon eVTOL manned drone

The Recon eVTOL is an electric vehicle with a vertical takeoff and landing system. The six-propeller multicopter is designed to carry one passenger weighing up to 91 kg. The Ryse Recon is equipped with an aluminum frame and weighs 130 kg. The autonomous flight time is 25 minutes, depending on pilot weight and prevailing wind conditions. Maximum flight speed is 93 km/h and cruising speed is closer to 65 km/h.

According to the developers, Ryse Recon is not intended for city use or commuting. Rather, it is a practical way to explore large areas of land. The device allows you to easily traverse topographically difficult and interesting terrain. So, the Ryse Recon can be used to survey the land, search for lost livestock, or check the condition of the soil.

2022-08-02 18:00:08 Denmark will build the world's first energy island

The world's first energy island will be the size of 18 soccer fields (120,000 square meters), but it is hoped to triple in size. It will serve as the center for 200 giant offshore wind turbines.

It is the largest construction project in Danish history, at an estimated cost of 210 billion kroner ($34 billion). It will supply electricity not only to Danes, but also to the power grids of other neighboring countries. Although these countries have not yet been described, Professor Jakob Ostergaard of the Technical University of Denmark told the BBC that Britain could win, as well as Germany or the Netherlands. Green hydrogen will also be used in shipping, aviation, industry and heavy transport.

The plan is to grow from the original 120,000 square meters to 460,000 square meters.
