10 Most Dangerous Staircases in The World (PHOTOS)

Dangerous Train Routes In The World… 😳 😘❤️

Also read:

As you climb these steps, make sure to watch where you step. Here are some of the most spectacular and dangerous staircases in the world. Stairs have been built for a very long time to aid in the ascent of heights and to lessen the amount of work that is required for this. However, in other regions of the world, stairs are so terrible that they appear to be nothing more than a series of corridors going to the underworld.

The Half Dome Cable Route is a scary walk that goes for 13 km and takes you to an altitude of about 4,800 ft. Before, because the trail was hard, there weren’t as many people on it, but now there are about 800 people on it every day. This hiking trail takes you to the Vernal and Nevada Falls, then into Yosemite Valley, and finally to the Half Dome.

One of the most impressive examples of architecture in the world can be seen in the unfinished church designed by the illustrious architect Antoni Gaudi’s vision for this Roman Catholic Church included the canopy of a nearby forest serving as the structure’s roof. The stairs are built so that they wind around a wall on one side and have no handrail on the other side. So, you should climb at your own risk.

Novel Smart Solar-Powered Freezer Truck Unveiled in Hong Kong

The transport sector is a significant contributor to greenhouse gas emissions in Hong Kong, accounting for 19% of total emissions. Supporting the development of green transport can help reduce air pollutant emissions. The Hong Kong Polytechnic University (PolyU) is committed to promoting research into green technologies to support Hong Kong’s goal of reducing the City’s total carbon emissions from the 2005 level by half before 2035 and achieving carbon neutrality before 2050.

A research team led by Prof. Eric Cheng, Professor of the Department of Electrical and Electronic Engineering at PolyU, received support from the “Innovation and Technology Support Program (Mid-stream, theme-based)” last June for the research project “Smart Refrigeration Truck Development Program—Power, Solar and Intelligence Method for Logistics and Storage.” The project is aimed at promoting the transformation of freezer trucks from traditional fuel driven freezer system to smart electric driven and strengthening the wider adoption of solar energy.

After one year, the PolyU team has successfully developed a novel freezer truck that supports a solar-powered freezer system and features vehicle-connected power storage and sharing technology. The project has received staunch support from the government, academia and industry, including from Sunlight Eco-tech Limited, Advanced Sunlight Pty Limited from Australia, and the Electrical and Mechanical Services Department.

Research team designs biomimetic vision system based on praying mantis eyes

Self-driving cars occasionally crash because their visual systems can’t always process static or slow-moving objects in 3D space. In that regard, they’re like the monocular vision of many insects, whose compound eyes provide great motion-tracking and a wide field of view but poor depth perception.

Except for the praying mantis.

A praying mantis’s field of view also overlaps between its left and right eyes, creating binocular vision with depth perception in 3D space.

Cylinder sails promise up to 90% fuel consumption cut for cargo ships

Looking like a set of bridge supports that were accidentally installed on a cargo ship, a new wind-driven system by startup CoFlow Jet promises to reduce ship fuel costs by up to 90% using stationary cylinders with no moving parts.

Between rising fuel costs and increasing government mandates requiring shipping companies to go carbon neutral by 2050, there’s a strong push to increase the efficiency of cargo ships while reducing their emissions. One way of doing this is to take a page from the history books and readopt sails to harness the wind.

On the surface, that makes sense. Sails have been propelling ships all over the world for millennia and were still used for commercial transport until after the Second World War. However, there are two problems with sails that have pushed them out of the cargo market for all except the most local of niches.

Air Taxi Company is Exploring a Hydrogen-Powered Aircraft

An electric air taxi startup is developing an aircraft powered by tomorrow’s fuel: hydrogen. The concept is a hydrogen-powered version of its vertical takeoff and landing aircraft. This fueling power could enable longer routes between cities.

The electric air taxi startup Joby is known for its electric vertical takeoff and landing aircraft (eVOTL) or an air taxi. The company is testing sustainable fuel instead of a battery to power this vehicle. Hydrogen fuel cells are already used in cars, trucks, and industrial equipment. However, using the fuel in aircraft is a game changer. For example, the aviation industry faces much pressure due to its greenhouse gas emissions. Google even added an emissions tracker when looking for a flight.

The company announced that it successfully flew a 523-mile demonstration flight using its one-of-a-kind hydrogen air taxi. The aircraft was tested last month in California and involved a converted prototype of one of its eVOTL aircraft already in development. It’s equipped with a hydrogen fuel cell and hydrogen-electric propulsion. And get this: the only emission is a trail of water vapor.

BHP’s Spence copper mine in Chile now fully autonomous

BHP’s (ASX, NYSE: BHP) Spence copper mine in Chile has celebrated three months of being the company’s first fully autonomous operation, a status reached in April after a two-year journey that included converting its trucks fleet and drilling rigs.

Spence, which produced 249,000 tonnes of copper last year, is BHP’s second largest copper mine behind Escondida, the world’s biggest copper operation. In the three months to July 29, the copper operation has moved 80 million tonnes of material without any safety incidents, surpassing the production plan to date, BHP said.
