No other tech firm in history has managed to infiltrate and influence daily life to the same insane extent as search giant Google. The Californian company’s impact on how we work, play, and settle drunken arguments is so well documented it more or less goes without saying. What’s perhaps less well understood is just how vast the company has grown, since deciding it wasn’t satisfied simply being everybody’s omniscient online know-it-all. So today we’re on the search for just what this modern-day behemoth actually does and asking the question – how big is Google?
It’s the first day of CES 2021 and CNET is the place to kick off the tech decade with wall-to-wall coverage from inside the Consumer Electronics Show.

As CES goes online for the first time, we preview the most-anticipated products and trends (and what’s missing) at the world’s biggest tech show.
Learn how our team of engineers took the mid-engine Corvette to the next level. From the development at Nürburgring to brand new architecture and technology.
Fusing athleticism, teamwork, and technology, the monohulls competing for the 36th #AmericasCup are the fastest in the world. It was August 2012 when the sailing world was turned upside down by a 72 foot catamaran flying in the Hauraki Gulf. Emirates Team New Zealand had brought the foils to the America’s Cup and changed the face of top-level yacht racing forever. Since then the increase in performance for America’s Cup boats has been greater than at any point in the 170-year history of the event. Six years later, in 2018, the publication of the AC75 Class rule, marked the beginning of a new sailing era. Nowadays foils are commonplace, but the engineering and sailing techniques needed to get the AC75 to fly are completely different from anything seen before.
Airbus has revealed three concepts for the world’s first zero-emission commercial aircraft which could enter service by 2035. These concepts each represent a different approach to achieving zero-emission flight, exploring various technology pathways and aerodynamic configurations in order to support the company’s ambition of leading the way in the decarbonisation of the entire aviation industry.
All of these concepts rely on hydrogen as a primary power source – an option which Airbus believes holds exceptional promise as a clean aviation fuel and is likely to be a solution for aerospace and many other industries to meet their climate-neutral targets.
The three concepts – all codenamed “ZEROe” – for a first climate neutral zero-emission commercial aircraft include:
•A turbofan design (120-200 passengers) with a range of 2,000+ nautical miles, capable of operating transcontinentally and powered by a modified gas-turbine engine running on hydrogen, rather than jet fuel, through combustion. The liquid hydrogen will be stored and distributed via tanks located behind the rear pressure bulkhead.
• A turboprop design (up to 100 passengers) using a turboprop engine instead of a turbofan and also powered by hydrogen combustion in modified gas-turbine engines, which would be capable of traveling more than 1,000 nautical miles, making it a perfect option for short-haul trips.
• A “blended-wing body” design (up to 200 passengers) concept in which the wings merge with the main body of the aircraft with a range similar to that of the turbofan concept. The exceptionally wide fuselage opens up multiple options for hydrogen storage and distribution, and for cabin layout.
As side hustles go, Elon Musk’s rocket company SpaceX is really quite something. Entirely separate from the humdrum day job at Tesla, where his only real challenge is weaning humanity off the internal combustion engine, Musk’s multi-billion dollar SpaceX operation sets itself no less a target than bringing down the cost of space travel and ultimately helping mankind colonise Mars.
Spoiler alert – firing gigantic rockets into space every other week is not a cheap undertaking. And while there’s no question Elon Musk has a few bucks to his name, his pockets aren’t bottomless. Somehow, all those dazzling launches – and landings – need to pay for themselves. So strap in and get ready for ignition sequence, while we investigate today’s burning question – how does SpaceX make money?
In October this year, influential investment bank Morgan Stanley went on record saying it believed SpaceX would very soon be worth a cool 100 billion dollars.
A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind’s kinetic energy into electrical energy. Wind turbines are manufactured in a wide range of vertical and horizontal axis.
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.
The science required for a helicopter to achieve flight is a lot more complicated than it might seem.
