Smaller, faster-charging batteries are the answer for affordable and sustainable electric vehicles (EVs) for everyone, everywhere. The ability to quickly refill energy is profoundly important in order to reduce EV cost and demand for critical minerals. In this talk I will present asymmetric temperature modulation (ATM) approach to enabling 10-minute fast charging of energy-dense Li-ion batteries in any temperatures (even at -60°C) while still delivering remarkable cycle life. Recent disastrous events at EV charging stations caused by an arctic blast in Chicago will be given as an example of the dire need for quick energy refill in the extreme cold. Battery fast charging must also work in hot summers along with high-temperature stability of cycling and storage. We shall present novel thermal management concepts for extreme fast charging in both extreme cold and hot conditions. Overall, our development points to a new paradigm of battery design and thermal management without having to trade-off among fast charge, safety, lifetime, and cost.

Electricity is generated at Lamma Power Station located at Po Lo Tsui of Lamma Island. The power station has a total installed capacity of 3,737MW made up of three 250MW coal-fired units, five 350MW coal-fired units, one 55MW gas turbines, four 125MW gas turbines, one 335MW combined cycle unit, one 345MW combined cycle unit, one 800kW wind turbine and one 1MW solar power system. Lamma Power Station provides a safe and reliable supply of electricity for more than 570,000 customers on Hong Kong Island and Lamma Island, and contributes to HK Electric’s world class reliability of more than 99.999%. Following the opening of Hong Kong's first wind power station, Lamma Winds, in 2006, an extension to the power station that burns the more environmentally friendly natural gas became operational the same year. In line with Government policy that aims to increase the use of gas, gas-fired generation has been increased to over 30% of the total output in 2010 when another gas-fired unit was put on use.

This channel contains the complete 8.01x (Physics I: Classical Mechanics), 8.02x (Physics II: Electricity and Magnetism) and 8.03 (Physics III: Vibrations and Waves) lectures as presented by Walter Lewin in the fall of 1999, spring of 2002 and fall of 2004. The 8.01x and 8.02x edX lectures are high resolution (480p) versions of the more commonly seen OCW versions. Some edits were also made by Lewin. 8.03 is the OCW version, also in a 480p resolution. Links to lecture notes, assignments/solutions and exams/solutions are added. Playlists with Help Sessions for 8.01x, 8.02x and 8.03 are also available. They are "mini lectures". The problems discussed in these videos should be apparent after watching the first few minutes. Other playlists show Lewin in various appearances and his Bi-Weekly Physics problems/solutions and several excellent lectures by Feynman and others.

The modern world depends on electricity. It’s a crucial resource, especially in urban areas, but electricity can’t be created, stored, and provided at a later time. The instant it’s produced, it’s used no matter how far apart the producer is from the user. And the infrastructure that makes all this possible is one of humanity’s most important and fascinating engineering achievements: the power grid.

This video continues the series on the power grid by diving deeper into the engineering of large-scale electricity generation. The importance of electricity in our modern world can hardly be overstated. What was a luxury a hundred years ago is now a critical component to the safety, prosperity, and well-being of nearly everyone. Generation is the first step electricity takes on its journey through the power grid, the gigantic machine that delivers energy to millions of people day in and day out. So how does it work?

Untangling the various equipment you might see in an electrical substation. In many ways, the grid is a one-size-fits-all system - a gigantic machine to which we all connect spinning in perfect synchrony across, in some cases, an entire continent. On the other hand, our electricity needs, including when we need it, how much we need, and how reliably it should be delivered vary widely. Substations play a critical role in controlling and protecting the power grid.

Discussing some of the fascinating engineering that goes into overhead electric power transmission lines. In the past, power generating plants were only able to serve their local areas. As power plants grew larger and further away from populated areas, the need for ways to efficiently move electricity over long distances has become more and more important. Stringing power lines across the landscape to connect cities to power plants may seem as simple as connecting an extension cord to an outlet, but the engineering behind these electric superhighways is more complicated and fascinating than you might think.

This video explores the protective systems that keep the power grid from self destructing. We usually think of the power grid in terms of its visible parts: power plants, high-voltage lines, and substations. But, much of the complexity of power grid comes in how we protect it when things go wrong. When your power goes out, it’s easy to be frustrated at the inconvenience, but consider also being thankful that it probably means things are working as designed to protect the grid as a whole and ensure a speedy and cost-effective repair to the fault.
