ТОП 10 — Самые МОЩНЫЕ Маслкары и их РЕАЛЬНЫЕ Лошадиные Силы
Всё ВРАНЬЁ!!! Американские маслкары не обладали той мощностью, о которой все говорят!!! Mustang BOSS 429 не имел 375 л.с. под капотом!!! 426 HEMI никогда не выдавал 425 лошадей!!!
Могучие моторы этих, и многих других выдающихся машин золотой эры американских маслкаров на самом деле были ЕЩЕ МОЩНЕЕ!!!
Смотрите на канале АвтоТРЕНДЫ новое видео, посвященное 10 самым мощным классическим двигателям V8 с учетом реального количества лошадиных сил, которым они обладали…

What if your electric car could travel 1000 miles on a single charge, charge in 10 minutes, and last for 1 million miles?
Today just about every electric car uses lithium ion batteries. They’re pretty good, but ultimately are heavy and have long charging times for the amount of energy they can store.
According to Elon Musk, battery modules are the main limiting factor in electric vehicle life. In 2019 he said the Tesla Model 3 drive unit is rated for 1 million miles, but the battery isn’t as long lasting.
To handle the predicted demand explosion for electric vehicles over the coming decades, we’ll need to create a breakthrough battery that is cheaper, longer lasting, more durable, and more efficient. We must also address the issues of political and environmental sustainability to ensure batteries remain tenable in an increasingly electric future.
Over 80% of world’s lithium deposits are found in China, and current technology also relies heavily on cobalt, an element mostly found in the Democratic Republic of Congo.
After Tesla’s recent battery day, where Elon Musk announced a larger, tabless 4680 battery cell with improved energy density, greater ease of manufacturing, and lower cost. The world’s attention is now more focused on batteries than ever before, but Tesla isn’t the only show in town.
Lithium air batteries. Metal air batteries have been around for a while. You might find a little zinc air button cell in a hearing aid, for example, but scaled up aluminum and lithium air chemistries are also promising for the automotive and aerospace industries. The potential for lightweight batteries with high energy storage makes this battery technology promising. Lithium air batteries could have a maximum theoretical specific energy of 3,460 W h/kg, almost 10 times more than lithium ion. NASA researchers have also been investigating lithium air batteries for use in aircraft. This technology still has a long way to go before your take your next business trip is in an electric plane.
Nanotech Batteries. Nanotechnology has been a buzzword for several decades, but is now finding applications in everything from nanoelectronics to biomedical engineering, and body armor to extra-slippery clothing irons. Nanomaterials make use of particles and structures 1-100 nanometers in size, essentially one size up from the molecular scale. Carbon nanostructures also show great promise. Graphene is one of the most exciting of these. Amprius go one stage further with their anodes of ‘100% silicon nanowire’. The maker claims that they can achieve 500 Wh/kg which is in the range suitable for enabling electric aircraft in partnership with Airbus. Nanomaterial research is promising
Lithium sulphur batteries are one emerging technology that can offer greatly improved energy densities compared to lithium-ion. The theoretical maximum specific energy of this chemistry is 2,567 Wh/kg compared to lithium ion’s 350 Wh/kg maximum.
Solid state electrolytes. A common theme in emerging technologies so far has been researchers’ desire to develop solid state electrolytes. These would replace flammable organic liquids with stable, crystalline or glassy-state solids, or polymer-base. It is hoped that using these solid electrolytes would enable the use of metallic lithium electrodes to provide higher output voltages and allow for increased energy density. Panasonic have also been looking into solid state electrolytes. It is notable that Tesla have been partnered with Panasonic in their existing lithium-ion manufacturing capacity, but it is Toyota who have publicly announced their collaboration with Panasonic to develop next generation solid state batteries.
Samsung too are working on solid state batteries.
Dual carbon batteries. Two carbon electrodes and a non-toxic electrolyte with the ability to extract more power than from conventional lithium ion, and their ability to charge 20 times faster, and these lithium-ion variants could be the future for electric vehicles.
Better batteries are also important for the advancement of stationary storage from renewable energy sources such as solar power. Tesla is also making headway into this sector, with products like the powerwall home battery, and powerpack commercial energy storage products.
The technologies discussed in this video could have huge implications on different battery powered transportation options besides just electric cars. Imagine the potential in everything from electric bikes to electric scooters and electric boats to electric airplanes. Consumer electronics also stand to experience vast improvements in battery life in devices such as smart phones, laptops, cameras, and more. The future is electric!

Приветствую вас на своем канале, посвященному опытам по неорганической и органической химии! Здесь вы сможете найти множество химических опытов, в каждом из которых присутствуют объяснения, которые будут понятны даже самым далеким от химии людям. В своих видео опытах я также указываю формулы, которые помогут вам понять суть химических реакций и превращений. Если у вас в школе были проблемы в восприятии трудных химических реакций и формул, то некоторые из моих видео вы сможете использовать в качестве самоучителя по химии. Также, некоторые опыты из моих видео можно будет повторить дома, конечно же, с соблюдением всех правил безопасности. Многие из опытов, которые приведены в моих видео, показывают детям и используют в качестве классических демонстрационных опытов для школьников или студентов. Каждый опыт максимально понятно объяснит вам происходящее, химия теперь доступна для всех, включая настоящих чайников!

Annual Malcolm Haines Memorial Concert
Colin Lawson clarinet

Abe Buckoke guest narrator
The Revolutionary Drawing Room is a flexible group performing repertoire of the late eighteenth and early nineteenth centuries, the age of the great European revolutions. They use instruments of the period and aim to bring to audiences the sense of exploration in which composers and players of the time were engaged. Rachel Stott’s ‘Euphonia’ takes its name from a story in Berlioz’s Evenings in the Orchestra, which describes a German city in the year 2344, devoted exclusively to music. Composed during lockdown in spring 2020, ‘Euphonia’ imagines four musicians from this city escaping in a hot air balloon to seek their fortune in London. Reicha’s Clarinet Quintet, a rarely heard gem, demonstrates a winning Classical sensibility and a keen melodic imagination worthy of his most prominent contemporaries.
