Every other Wednesday we present a new video, so join us to see the truth laid bare…
Machines are evolving 10 million times faster than we are. Are you ready for robots that run our homes, watch our neighborhoods and even fight our wars? One day in the not too distant future, robots will travel to the far reaches of the universe, they will be the first to colonise new worlds. Robots will lead the way in the exploration of deep space.
Robots, machines of our nightmares, or servants of man? In the 1930s film Metropolis the robot was an evil character, it represented our darkest fears. By the 1950s they had become even more sinister and powerful, but over that last few decades our opinions of robots have dramatically changed, they’ve been reinvented as the police force of the future. But can real robots match the exploits of their celluloid cousins?
While the movies were creating ruthless men of steel, real robots were starting their own painful march into the world. Robots are still basic but over the past few decades they have advanced enormously. Before robots can become the masters of the universe, or even the servants of mankind, they need to accomplish one important thing, they need to move around.
This 1999 documentary includes interviews with prominent roboticists and artificial intelligence specialists. Beginning with robot locomotion and historical clips of ingenious experiments from MIT's Leg Laboratory, BigDog's ancestors dynamically walk, hop, trot, and perform impressive gymnastics. To find out the best way for a robot to move around the scientists look to nature. There have been many attempts to copy nature, some successful, others less than perfect.
Some of the robots discussed in this documentary:
Massachusetts Institute of Technology’s Genghis II
Hermes the Hexapod
Micro-robot Cricket
Mine Clearer Ariel
Ambler the Massive Six-legged Planetary Rover
Adaptive Suspension Vehicle
Odetics Inc’s Odex 1

Solar Panels on a Tesla

Solar Panels on a Tesla



Electric cars and solar panels seem like a match made in heaven: free, clean power as long as the sun shines. A self reliant, solar car that’s not dependent on the power grid could recharge sustainably from anywhere you dare to venture.
So, have you ever wondered about bolting solar panels on your Tesla? And why don’t all electric cars come equipped with solar panels for a sleek charge-on-the-go solution? In fact, with improving solar technology and clever ground-up engineering, a few self-charging solar cars are just at the point of coming to market. In this video we’ll delve into the practicalities of solar power for vehicles and have a look at some of the early adopters of this emerging technology.
In 2017, Elon Musk suggested that Tesla would offer optional solar tiles on the roof of the model 3, but later retracted the statement. This was Elon Musk’s idea in 2017 – that car roofs are small and inefficiently angled platforms for viable solar installations, and charging from a home solar installation made more sense. You could even charge at night on stored solar and cheaper off peak electricity. However, Elon might have changed his mind, confirming that the Cybertruck will offer a solar roof option on the truck’s bed.
To understand if a solar car could really work, we need to find out how much solar energy the surface of a car can capture, and how much range that energy will provide under realistic driving conditions.
So let’s take a sedan the size of a Tesla Model S, almost 5 m long and 2 m wide, and put a totally impractical, hypothetical array of solar cells covering the whole plan-view rectangular area of 10 square meters.
When it comes down to it, solar vehicles are all about efficiency. It’s a matter of energy to weight. A practical solar car would really need to be designed from the ground up with reduced weight and low aerodynamic drag, to create a vehicle with more favorable energy density. For as far as electric cars have come in the last decade, the energy density of gasoline is still far greater than lithium ion batteries.
Teams gather each year in Australia to race pure solar cars across the continent from Darwin to Adelaide under the scorching desert sun for the World Solar Challenge. Consistent winners of this class have been the evolving Stella series from the University of Eindhoven, the team from which Lightyear sprang in 2016. Lightyear one reevaluated every component of the car and used lighter materials like aluminum and carbon fiber, to build a lighter vehicle with the best aerodynamic coefficient of any car on the market. Four independently driven in-wheel motors also lower the cars weight, and improve powertrain efficiency.
Sono Motors on the other hand, are starting with a more affordable $29,000 compact solar car designed for urban use. In designing the Scion prototype. Sono’s proudest new technology integrates solar cells into polymer body panels to replace conventional painted metal bodywork.
Toyota has experimented with a demonstration Prius with high efficiency thin-film triple junction cells made by Sharp, and Hanergy Solar, a Chinese manufacturer of thin film panels, have also demonstrated prototype cars with panels that can harvest 8-10 kWh per day and supplied such panels to Aston Martin for their GTE racing car.
Most solar panels rely on cells made from semiconducting silicon crystals, which convert sunlight to electricity at around 15%-19%, but new technologies are in the works to create higher efficiency solar cells utilizing new materials. As the future unfolds, and more cutting edge solar technologies come to market, we can see self charging solar electric vehicles become more and more practical, as cells get more and more efficient. A future cell technology with efficiencies above 50% would be a game changer, and probably make solar cars ubiquitous.
Heavy batteries are a limiting factor in the feasibility of solar cars. A breakthrough battery with more favorable energy to weight characteristics would revolutionize electric transportation, and make solar cars far more realistic.
Promising new technologies that utilize materials like graphene, solid polymers, and ceramics are currently in research and development, and are poised to create the next generation of powerful batteries with higher energy density, greater service life, faster charging, improved safety, and potentially even lower costs.
So should you mount a solar panel on your Tesla to make it a solar tesla? Watch the video to find out.

The Future of Energy Storage - Professor Yet-Ming Chiang, MIT

The Future of Energy Storage — Professor Yet-Ming Chiang, MIT



What have been the key battery technology breakthroughs to get us to where we are now? What are some new opportunities for large-scale energy storage & what's MIT doing? What are some key lessons for startups to be successful in the battery industry?
Energy storage will play an increasingly important role in a decarbonized world. From electric vehicles to grid resiliency, batteries will impact the ultimate success of numerous industries that are critical to a low carbon society. Professor Yet-Ming Chiang, one of the world’s most prominent researchers in energy storage, will give a personal perspective on some of the challenges and opportunities for better and cheaper energy storage.
From a historical perspective, battery performance has improved steadily, but now the divergent needs for batteries in high energy density applications such as EVs (and, coming soon, electric aviation), and those for grid storage, which emphasizes ultra-low cost and earth-abundant materials, are becoming clear. He will give examples of emerging innovations that may address these different needs, including solid-state and other batteries that use alkali metal electrodes, and approaches that make use of the most widely available electroactive elements. The expectation is that the audience will come away with a realistic but exciting roadmap of possible areas of innovation for energy storage.
Finally, he will conclude with his personal experiences in building battery enterprises. Battery technologies are notoriously difficult to scale given high technology risk and high development costs. Yet-Ming will share some of the unique lessons learned at startups he has co-founded, including A123, 24M, and most recently Form Energy.
Prof. Chiang's research focuses on the design, synthesis, and characterization of advanced inorganic materials and related devices. Current topics include new cathode and anode materials for lithium ion batteries, phase transformations in electroactive materials, electrochemical device design, electrochemical-to-mechanical energy conversion, self-assembling colloids, and the stability and defect chemical properties of interfaces in inorganic materials.

ВЫМИРАЮЩИЕ ЖИВОТНЫЕ, КОТОРЫЕ СКОРО БУДУТ ЗАМЕНЕНЫ

ВЫМИРАЮЩИЕ ЖИВОТНЫЕ, КОТОРЫЕ СКОРО БУДУТ ЗАМЕНЕНЫ



Вы наверняка не раз хотя бы отдаленно слышали о том вреде, который наносит нашей планете деятельность человека. Одно из самых серьёзных последствий этого вреда, который выражается прежде всего в изменении климата, — это вымирание животных. По данным ООН, на сегодняшний день около миллиону видов животных грозит исчезновение. Это значит, что их популяция и скорость размножения слишком малы, чтобы рассчитывать на дальнейшее существование вида даже при условии активного вмешательства учёных. Сегодня мы расскажем вам о том, какие же животные в скором времени могут полностью пропасть с лица Земли, и кто их сможет заменить.
