Space Exploration: Moon Landing & Dragon, Falcon and SpaceX | Trajectory | Free Documentary



Trajectory: Milestones in Space Exploration — Episode 10: Moon Landing; Dragon, Falcon & SpaceX and Gaia | Space Documentary
Today, although a cloud of satellites surrounds the planet, many records set during the early decades of space exploration remain unsurpassed. It's more than forty years since the last man walked on the moon and the world no longer has a reusable spacecraft. Trajectory looks at milestones in space exploration along with the latest scientific and commercial developments.
Space Milestones:
— To The Moon: The Apollo program achieves its major objective.
— Dragon, Falcon & SpaceX: New directions in re-usable spacecraft.
— Gaia: Mapping our galaxy in unprecedented detail.

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 truth about graphene — what's the hold up?



Go to brilliant.org/Undecided you can sign up for free. And also, the first 200 people will get 20% off their annual premium membership. The truth about graphene. Ever since it was first discovered in 2004, graphene has been hailed as one of the most important breakthroughs in materials since the plastics revolution more than a century ago. The early predictions were that graphene would almost immediately enable the kinds of products and technologies that we're used to seeing in sci-fi movies. Cut to more than a decade and a half later and that still hasn't happened. Not even close. With opinions split between people overhyping graphene or calling it a massive disappointment, it's time we got to the truth of what is really happening with this so-called 'wonder material'.

Китайский ЭЛЕКТРОМОБИЛЬ. КАК КУПИТЬ? Обзор BYD e6/URBAN ELECTRIC



Всем привет, это Степан Мостовой! Вы на моем канале URBAN ELECTRIC, посвященном электрокарам. В этом видео я попробую ответить на популярный вопрос среди вас, подписчики. А именно: «Как купить электрокар в Китае? Как привезти его из Китая в Украину, Россию, Белорусь, Казахстан и т.д.?». А еще возьму интервью у владельца китайского электромобиля BYD e6. BYD в свое время очень хотели зайти на рынок Гонконга, но их опередила Toyota. Тогда модель e6 разошлась среди «своих». Именно таким «своим» и оказался мой герой. Хотите знать подробности этой истории — бегом смотреть видео!
