It’s well over a decade since Amazon launched its Prime delivery service; in fact it was 2007 when the company first introduced us to unlimited next-day shipping on what was at the time almost a million products.
But in 13 years, we have seen little change. That is, until recently. Many areas now offer same-day delivery, but behind closed doors Amazon had been working on an ambitious plan to realise almost instant delivery. The goal? Just 30 minutes, from the click of the ‘order now’ button to the tangible products, in our hands.
Every delivery company can agree that the final mile or so of a product’s journey is the most expensive. As it leaves a shipping container, and steps away from the lorry’s vessel, it enters the smallest vehicle yet – vans, and sometimes cars. Rather than carrying millions of products, a driver can now only carry a few dozen. Employing thousands of drivers comes at incredible cost to shipping companies.
Is cash still king? The coronavirus pandemic may cause a drastic decline in cash usage due to the risk of contamination. The unprecedented surge in the demand for contactless payment has also shown outstanding performances for major companies offering cashless payment methods, like Apple, Square and Paypal. Could covid-19 signal the end of cash in the United States and can the U.S. really function without physical currency?
Hyundai says it will introduce an electric vehicle-only platform early next year that will use its own battery technology to cut production time and costs.
What if our buildings produced more energy than they used? From the United States to Hong Kong, these projects prove it can be done.
A zero-energy building (ZE), also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), net zero building is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site,[1][2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels.
Google Maps has taken on competitors like MapQuest, Yahoo and Apple. But after a decade of investing, collecting data and billions of images through Street View, Google has over a billion monthly users. It updated tens of thousands of times a day and has mapped more than 220 countries and territories. Here’s a look at how Google came to dominate maps.
The 2021 Toyota Mirai is the second generation of zero emission hydrogen fuel cell electric sedan.
One of the principal aims for the new 2021 Mirai has been to give the car a stronger emotional appeal, making it a car that people will be attracted to by its looks and the way it drives, as well its eco-performance. The new GA-L platform and Toyota’s advances in FCEV technologies have made this possible. Toyota’s new fuel cell stack and fuel cell power converter (FCPC) have been developed specifically for use with the GA-L platform.
The designers have been able to bring all the elements together in the stack frame (including the water pumps, intercooler, air conditioning and air compressors and the hydrogen recirculation pump) with each part made smaller and lighter, while at the same time improving performance. The stack case itself has been made smaller by using Friction Stir Welding, reducing the gap between the fuel cell and casing.
The new Mirai is equipped with lithium-ion high-voltage battery in place of the current model’s nickel-metal hydride unit. Although smaller in size, it is more energy-dense, giving higher output and superior environmental performance. Containing 84 cells, it has a 310.8 rated voltage compared to 244.8, and a 4.0 Ah capacity, versus 6.5 Ah. Overall weight has been reduced from 46.9 to 44.6 kg. The output has improved from 25.5 kW x 10 seconds to 31.5 kW x 10 seconds.
The battery’s smaller dimensions have allowed it to be positioned behind the rear seats, avoiding intrusion in the load compartment. An optimised air-cooling path has been designed, with discreet inlets either side of the rear seats. The environmental benefit of driving the Toyota Mirai go beyond zero emissions to “negative emissions” – the car effectively cleans the air as it moves. A Toyota innovation, a catalyst-type filter is incorporated in the air intake.
As air is drawn into the vehicle to supply the fuel cell, an electric charge on the non-woven fabric filter element captures microscopic particles of pollutants, including sulphur dioxide (SO2), nitrous oxides (NOx) and PM 2.5 particulates. The system is effective in removing 90 to 100% of particles between 0 and 2.5 microns in diameter from the air as it passes into the fuel cell system.
There’s a lot of buzz around self-driving cars, but autonomous-driving technology could revolutionize a different industry first — construction. That industry hasn’t changed much over the last several decades, according to some experts, making it an ideal candidate for automation.
“The way we build today is largely unchanged from the way we used to build 50 years ago,” said Gaurav Kikani, vice president of Built Robotics. “Within two years, I think we’re really going to turn the corner, and you’re going to see an explosion of robotics being used on construction sites.”
The industry is also faced with a labor shortage that the Covid-19 pandemic has further complicated. “Covid is making people step back and say, ‘hey, the way we’ve been doing things for a long time is just not sustainable,’” said Kevin Albert, founder and CEO of Canvas. “It is just a wake-up call for the industry.”
Canvas is one of several companies working on autonomous construction technology. Big players like Caterpillar and Komatsu, and start-ups like SafeAI and Built Robotics, see value in using autonomous machines to accelerate construction projects. The mining industry was one of the first to employ the use of self-driving tech.
Caterpillar began its first autonomy program more than 30 years ago. The company now has the largest fleet of autonomous haul trucks. Caterpillar says it’s hauled 2 billion metric tons in just over six years. Built Robotics is a San Francisco-based start-up founded by an ex-Google engineer that already has machinery out in the field. It’s automated several pieces of equipment, such as bulldozers and excavators.
“You can now collapse your construction timeline so you can knock out work overnight so that it’s ready for your human workers in the morning to speed them along,” Kikani said. SafeAI is another Silicon Valley start-up. It recently teamed up with Obayashi for a pilot program. It’s been retrofitting equipment like dump trucks, bulldozers and loaders. Robots are also helping inside.
San Francisco-based Canvas created an autonomous machine for finishing drywall and has worked on projects like the San Francisco International Airport and Chase Arena. Humans work alongside its robotic system. “Drywall is very hard work on the body,” Albert said. “And we’ve seen that 1 out of every 4 workers has to end their career early because of injuries. This will create longer careers for people and also enable people to join the trades that haven’t had access before.”
The construction industry is one of the largest sectors in the global economy, with about $10 trillion spent each year. That spending accounts for 13% of the world’s GDP, even though the sector’s annual productivity growth has only increased 1% over the past 20 years. According to McKinsey & Co., $1.6 trillion of additional value could be created through higher productivity, and autonomy would help the industry achieve that.

The Pentagon is the headquarters building of the United States Department of Defense. As a symbol of the U.S. military, the phrase The Pentagon is also often used as a metonym for the Department of Defense and its leadership.
The Pentagon is the world’s largest office building, with about 6,500,000 square feet (150 acres; 0.60 km2) of floor space, of which 3,700,000 sq ft (85 acres; 0.34 km2) are used as offices.[7][8] Some 23,000 military and civilian employees,[8] and another 3,000 non-defense support personnel, work in the Pentagon. It has five sides, five floors above ground, two basement levels, and five ring corridors per floor with a total of 17.5 miles (28.2 km)[8] of corridors. The central five-acre (2.0 ha) pentagonal plaza is nicknamed “ground zero” on the presumption that it would be a prime target in a nuclear war.
Every legacy has a compelling origin. The soon-to-be-launched Landsat 9 is the intellectual and technical product of eight generations of Landsat missions, spanning nearly 50 years.
Episode One answers the question “why?” Why did the specific years between 1962 and 1972 call for a such a mission? Why did leadership across agencies commit to its fruition? Why was the knowledge it could reveal important to the advancing study of earth science?
In this episode, we’re introduced to William Pecora and Stewart Udall, two men who propelled the project into reality, as well as Virginia Norwood who breathed life into new technology. Like any worthwhile endeavor, Landsat encountered its fair share of resistance. Episode one explores how those challenges were overcome with the launch of Landsat 1, signifying a bold step into a new paradigm.
