Every summer when I was growing up, I would fly from my home in Canada to visit my grandparents, who lived in Mumbai, India. Now, Canadian summers are pretty mild at best –about 22 degrees Celsius or 72 degrees Fahrenheit is a typical summer’s day, and not too hot. Mumbai, on the other hand, is a hot and humid place well into the 30s Celsius or 90s Fahrenheit. As soon as I’d reach it, I’d ask, “How could anyone live, work or sleep in such weather?” To make things worse, my grandparents didn’t have an air conditioner. And while I tried my very, very best, I was never able to persuade them to get one. But this is changing, and fast.
====================================
English Tips: 5 Tips for self-study speaking English Naturally
====================================

Cooling systems today collectively account for 17 percent of the electricity we use worldwide. This includes everything from the air conditioners I so desperately wanted during my summer vacations, to the refrigeration systems that keep our food safe and cold for us in our supermarkets, to the industrial scale systems that keep our data centers operational. Collectively, these systems account for eight percent of global greenhouse gas emissions.
01:27
But what keeps me up at night is that our energy use for cooling might grow six fold by the year 2050, primarily driven by increasing usage in Asian and African countries. I’ve seen this firsthand. Nearly every apartment in and around my grandmother’s place now has an air conditioner.
And that is, emphatically, a good thing for the health, well-being and productivity of people living in warmer climates. However, one of the most alarming things about climate change is that the warmer our planet gets, the more we’re going to need cooling systems — systems that are themselves large emitters of greenhouse gas emissions.
example: The minister has issued an emphatic rejection of the accusation.
This then has the potential to cause a feedback loop, where cooling systems alone could become one of our biggest sources of greenhouse gases later this century. In the worst case, we might need more than 10 trillion kilowatt-hours of electricity every year, just for cooling, by the year 2100. That’s half our electricity supply today. Just for cooling. But this also point us to an amazing opportunity. A 10 or 20 percent improvement in the efficiency of every cooling system could actually have an enormous impact on our greenhouse gas emissions, both today and later this century. And it could help us avert that worst-case feedback loop.
02:54
I’m a scientist who thinks a lot about light and heat. In particular, how new materials allow us to alter the flow of these basic elements of nature in ways we might have once thought impossible. So, while I always understood the value of cooling during my summer vacations, I actually wound up working on this problem because of an intellectual puzzle that I came across about six years ago. How were ancient peoples able to make ice in desert climates? This is a picture of an ice house, also called a Yakhchal, located in the southwest of Iran. There are ruins of dozens of such structures throughout Iran, with evidence of similar such buildings throughout the rest of the Middle East and all the way to China.
03:42
The people who operated this ice house many centuries ago, would pour water in the pool you see on the left in the early evening hours, as the sun set. And then something amazing happened. Even though the air temperature might be above freezing, say five degrees Celsius or 41 degrees Fahrenheit, the water would freeze.
The ice generated would then be collected in the early morning hours and stored for use in the building you see on the right, all the way through the summer months. You’ve actually likely seen something very similar at play if you’ve ever noticed frost form on the ground on a clear night, even when the air temperature is well above freezing. But wait. How did the water freeze if the air temperature is above freezing? Evaporation could have played an effect, but that’s not enough to actually cause the water to become ice. Something else must have cooled it down.
04:34
Think about a pie cooling on a windowsill. For it to be able to cool down, its heat needs to flow somewhere cooler. Namely, the air that surrounds it. As implausible as it may sound, for that pool of water, its heat is actually flowing to the cold of space.
04:54
How is this possible? Well, that pool of water, like most natural materials, sends out its heat as light. This is a concept known as thermal radiation. In fact, we’re all sending out our heat as infrared light right now, to each other and our surroundings. We can actually visualize this with thermal camera sand the images they produce, like the ones I’m showing you right now. So that pool of water is sending out its heat upward towards the atmosphere. The atmosphere and the molecules in it absorb some of that heat and send it back. That’s actually the greenhouse effect that’s responsible for climate change.
05:32
But here’s the critical thing to understand. Our atmosphere doesn’t absorb all of that heat. If it did, we’d be on a much warmer planet. At certain wavelengths, in particular between eight and 13 microns, our atmosphere has what’s known as a transmission window. This window allows some of the heat that goes up as infrared light to effectively escape, carrying away that pool’s heat. And it can escape to a place that is much, much colder.
The cold of this upper atmosphere and all the way out to outer space, which can be as cold as minus 270 degrees Celsius, or minus 454 degrees Fahrenheit. So that pool of water is able to send out more heat to the sky than the sky sends back to it. And because of that, the pool will cool down below its surroundings’ temperature. This is an effect known as night-sky cooling or radiative cooling. And it’s always been understood by climate scientists and meteorologists as a very important natural phenomenon.
06:40
When I came across all of this, it was towards the end of my PhD at Stanford. And I was amazed by its apparent simplicity as a cooling method, yet really puzzled. Why aren’t we making use of this? Now, scientists and engineers had investigated this idea in previous decades. But there turned out to be at least one big problem. It was called night-sky cooling for a reason. Why? Well, it’s a little thing called the sun. So, for the surface that’s doing the cooling, it needs to be able to face the sky. And during the middle of the day, when we might want something cold the most, unfortunately, that means you’re going to look up to the sun. And the sun heats most materials up enough to completely counteract this cooling effect.
07:28
My colleagues and I spend a lot of our time thinking about how we can structure materials at very small length scales such that they can do new and useful things with light — length scales smaller than the wavelength of light itself. Using insights from this field, known as nano photonics or meta materials research, we realized that there might be a way to make this possible during the day for the first time.
Meta material(n): A meta material is a material engineered to have a property that is not found in nature
07:49
To do this, I designed a multilayer optical material shown here in a microscope image. It’s more than 40 times thinner than a typical human hair. And it’s able to do two things simultaneously. First, it sends its heat out precisely where our atmosphere lets that heat out the best. We targeted the window to space. The second thing it does is it avoids getting heated up by the sun. It’s a very good mirror to sunlight. The first time I tested this was on a rooftop in Stanford that I’m showing you right here. I left the device out for a little while, and I walked up to it after a few minutes, and within seconds, I knew it was working. How? I touched it, and it felt cold.
Microscope (n): /ˈmaɪ.krə.skəʊp/: a device that uses lenses to make very small objects look larger
08:33
(Applause)
08:38
Just to emphasize how weird and counterintuitive this is: this material and others like it will get colder when we take them out of the shade, even though the sun is shining on it. I’m showing you data here from our very first experiment, where that material stayed more than five degrees Celsius, or nine degrees Fahrenheit, colder than the air temperature, even though the sun was shining directly on it.The manufacturing method we used to actually make this material already exists at large volume scales. So I was really excited, because not only do we make something cool, but we might actually have the opportunity to do something real and make it useful. That brings me to the next big question.
09:21
How do you actually save energy with this idea? Well, we believe the most direct way to save energy with this technology is as an efficiency boost for today’s air-conditioning and refrigeration systems. To do this, we’ve built fluid cooling panels, like the ones shown right here. These panels have a similar shape to solar water heaters, except they do the opposite — they cool the water, passively, using our specialized material. These panels can then be integrated with a component almost every cooling system has, called a condenser, to improve the system’s underlying efficiency. Our start-up, SkyCool Systems, has recently completed a field trial in Davis, California, shown right here. In that demonstration, we showed that we could actually improve the efficiency of that cooling system as much as 12 percent in the field.
10:07
Over the next year or two, I’m super excited to see this go to its first commercial-scale pilots in both the air conditioning and refrigeration space. In the future, we might be able to integrate these kinds of panels with higher efficiency building cooling systems to reduce their energy usage by two-thirds.And eventually, we might actually be able to build a cooling system that requires no electricity input at all. As a first step towards that, my colleagues at Stanford and I have shown that you could actually maintain something more than 42 degrees Celsius below the air temperature with better engineering.
10:45
Thank you.
10:46
(Applause)
10:51
So just imagine that — something that is below freezing on a hot summer’s day. So, while I’m very excited about all we can do for cooling, and I think there’s a lot yet to be done, as a scientist, I’m also drawn to a more profound opportunity that I believe this work highlights. We can use the cold darkness of space to improve the efficiency of every energy-related process here on earth. One such process I’d like to highlight are solar cells. They heat up under the sun and become less efficient the hotter they are. In 2015, we showed that with deliberate kinds of microstructures on top of a solar cell, we could take better advantage of this cooling effect to maintain a solar cell passively at a lower temperature. This allows the cell to operate more efficiently. We’re probing these kinds of opportunities further. We’re asking whether we can use the cold of space to help us with water conservation. Or perhaps with off-grid scenarios. Perhaps we could even directly generate power with this cold. There’s a large temperature difference between us here on earth and the cold of space. That difference, at least conceptually, could be used to drive something called a heat engine to generate electricity. Could we then make a nighttime power-generation device that generates useful amounts of electricity when solar cells don’t work? Could we generate light from darkness?
12:23
Central to this ability is being able to manage the thermal radiation that’s all around us. We’re constantly bathed in infrared light; if we could bend it to our will, we could profoundly change the flows of heat and energy that permeate around us every single day. This ability, coupled with the cold darkness of space, points us to a future where we, as a civilization, might be able to more intelligently manage our thermal energy footprint at the very largest scales.
12:57
As we confront climate change, I believe having this ability in our toolkit will prove to be essential. So, the next time you’re walking around outside, yes, do marvel at how the sun is essential to life on earth itself, but don’t forget that the rest of the sky has something to offer us as well.
13:20
Thank you.

AZUZ: There are a whole lot of people in this world who love pandas just because they`re cute. Whether or not you agree with them, you can`t say pandas are graceful, at least not this one at the national zoo. First, he gets stuck and then hilariously covers his head like he`s ashamed, and after a few moments, the inevitable happens.
The zoo says he`s fine, that pandas are built to withstand falls from trees and shortly afterward, he`s up climbing again.
Panda fall, panda go bamboom! May fall he should try a different tree, like one strong as oak, a type less willowy that wouldn`t cause whipping, one more spruce up. There are deciduously better options, someone should have a conifierence with him so he doesn`t get left in the larch.

Next story is about a CNN Hero named Neal Bermas, a businessman who`d traveled the world but was stopped suddenly by something he saw in Vietnam back in 1999. It led him to create STREETS International, an organization that offers help with the career path to threatened people between the ages of 16 and 22. By the end of this year, almost 250 people will have completed the program.
NEAL BERMAS, CNN HERO: I first came to Vietnam almost 20 years ago. There were bands of these four homeless kids on the streets and they were begging for milk, not for money. It touched me in the way that I couldn`t divorce myself from it.
What`s this fish called? Is it sea bass, no?
I`m a classic New Yorker. I`m passionate and I`m full of energy. I also did a lot of consulting for hotels and restaurants.
I knew the opportunities and so I thought, well, we start to build a bridge here in Vietnam. I was just crazy enough to think that I could make that happen and here we are.
Hello, everybody.
CROWD: Hello!
BERMAS: The young people in our program come from the whole country, all kinds of very, very difficult past. We have kids with HIV background, kids from leprosy villages. Some were already been trafficked sometimes more than once.
The banana breads are done.
BERMAS: We offer a structured program for 18 months, either in culinary or hospitality, and a very extensive and important life goes program.
Eating healthy.
English language instruction is a big part of what we do.
UNIDENTIFIED FEMALE: If I have good English, I can talk to the guests.
BERMAS: You`ll do great.
Beautiful.
The flagship eatery is our restaurant. It`s traditional Vietnamese food.
We have a rather large stretch of a campus between the housing where our young people live, our training center, our three different eateries. So, all the kids get a bicycle when they come to the program.
Part of the process of selecting and then getting to know our trainees is we see wherever they`re from.
How is mom?
All the young people in our program come from poverty. Poverty without enough to eat. Poverty without electricity, without plumbing.
UNIDENTIFIED FEMALE: Before, we hungry a lot in my family here.
Mr. Neal, he helps me to know about how to cooking and English, listening. I get a good job so I had get some money for my family now.
BERMAS: She was employee of the year last year. She just finished STREETS a few years ago. It`s an amazing story.
We raised the aspirations of the whole village and the whole village starts to think about, oh, maybe my kid too.
At the end of 18 months, 100 percent of our kids are fully employed, mostly in four and five star international hotels.
There were certainly moments I thought, are you sure you really want to give up the Upper West Side of Manhattan and come live in Vietnam? But, of course, I did and it was probably the best if not certainly the most meaningful decision I made in my adult life.

AZUZ (voice-over): Ten-second trivia:
What is the biggest factor in the price of gasoline (gas)?
Taxes, crude oil, distribution or refining costs?
The cost of crude oil is by far the biggest factor in what you pay for a gallon of gasoline.
CHRISTINE ROMANS, CNNMONEY, CHIEF BUSINESS CORRESPONDENT: Hitting the road? This will likely be the most expensive summer driving season in years. Filling up the tank will cost 14 percent more than last summer. Summer gas already tends to be more expensive, because federal and state laws require cleaner fuel for the busy and hot summer months.
But what else goes into the cost of filling up?
Well, those refining costs and profits are the smallest slice of what you pay at the pump. There`s also the cost of shipping and selling the gas itself and that depends on where you live. So do taxes, they make up about a fifth of the cost of your gasoline. But the biggest factor, it`s the price of crude oil and it`s rising.
AZUZ: There`s several reasons for that. One, the global economy is improving. When that`s at good shape, the demand for oil increases, causing its price to rise.
Two, political instability. Economic trouble in Venezuela, the ongoing civil war in Syria, uncertainty over the Iran nuclear deal, all of these things can cause oil prices to go up.
Three, major exporters of oil are pumping less of it. Some of them like Saudi Arabia want crude prices to be higher. Countries whose economies are dependent on oil sales generally have higher revenues when crude prices go up.
A downside to all of this though is what happens here.
The American Automobile Association says the U.S. national average for a gallon of gas is $2.86. That`s 52 cents higher per gallon than it was a year ago. And though it`s nowhere near the record of $4.11, hit in 2008, gas prices can eventually hurt the U.S. economy if they climb too high.

Great to see you watching as we kick off (start) a new week of CNN 10. Our season runs through Friday, June 1st. So, we have three weeks left on the air, starting today.
And we start today with a by-the-numbers look at the dangerous situation on Hawaii`s big island. That`s where the notoriously active Kilauea volcano has been erupting again for about a week and a half now.
Something to sure look out for while visiting Hawaii.
The first number we have is almost 2,000. It`s how many residents have been evacuated since the volcano started this eruption. Dozens of homes have been destroyed by lava.
Next, 12. That`s the distance in miles away from the crater that ash plumes could cover if an explosive eruption occurs. Scientists expect more of those in the days ahead and new lava flows are also possible.
Two-point-nine million is the estimated cost in dollars that Hawaiian officials expect will be needed to protect residents affected by the eruption and that`s for the next 30 days. U.S. President Donald Trump declared a major disaster in Hawaii on Friday. What does that is free up federal money and resources to help those affected?
Eighteen is the number of fissures, cracks on the ground where lava is seeping or spewing out, all caused by this eruption. Some of the fissures are miles away from Kilauea`s crater itself.
And that last number here is 1924. That`s the year when the Kilauea Volcano last behaved like this, according to some scientists. It was active for about three weeks then, sending ash high into the air and blasting blocks, weighing as much as 14 tons.
Now for a scientific look at how this eruption is playing out beneath the surface.
(BEGIN VIDEOTAPE)
IVAN CABRERA, CNN METEOROLOGIST: This is the layout here of Leilani Estates. There`s the evacuation zone. There are closed roads. The new fissures have impacted the eastern area. So, we`ll continue to monitor that, but this whole area, folks have been taken out of the way with good reason as you can imagine, as these things continue to pop out just every few hours, every day or so.
This is the lake, of course. This is the account (ph) that I`ve been showing you the last few days, noticing that as the lake drained its lava, it went underground and that`s the lava that`s coming up to the fissures. I think again, that`s going to be the main threat.
Notice as this continues to go down over the last several days, and one of our last pictures here, we can`t see the lava anymore. That`s an infrared camera, so the red you`re seeing there, that basically just heats signature here.
So, as that lava drops into the crater and into the basically a water table, let`s talk about what could potentially happen as far as this explosive eruption here as we check in with our volcano. There`s the lava and again what happens is, you get these rocks that will continue to fall down and that will create a blockage. And I don`t have to tell you what happens with the kinds of temperatures we`re seeing in here. We`re talking about temperatures well into 1,500 to 2,000 Celsius, right?
Those rocks blocking that passageway at some point are going to give and once that goes into the water tables as you see there, we`re going to have
watch out — quite an explosion here.
But again, I`m really not too concerned about this. It`s going to be a spectacular eruption when it happens, but I think, Cyril, because they have evacuated people out of the way, these boulders would sometimes can be the size of a school bus are not going to be impacting many folks. This is going to be within a few meters of the crater here and before that happens, you must imagine people will be getting out of the way, and that`s why they
closed the National Volcano Park there on the big island.

The post Learning English words with Cnn Student News: Topic 1 – Volcano first appeared on Helena Daily English.]]>My first call was to the pitcher’s wife. She quickly assented (to agree) to an interview in a bar near the stadium. I had a presentiment that the interview wasn’t going to go smoothly. By the time I arrived, she looked to be drowning her sorrows in her fifth or sixth martini. I asked about her husband’s activities the day he went missing.
She started rambling about their marital problems and how he wasn’t any good to her. When she got to the point, I found out that they’d had a huge fight that morning about an affair he’d been having with the team owner’s daughter. He stormed out of the house, and she hadn’t seen him since.
I decided to circumvent (to go around) the usual routes to meeting Lola McCurvy, the owner’s daughter, by staking out her favoring beauty salon. I don’t like to deal with a lot of personal assistants and such when I need to talk to someone. Miss McCurvy seemed quite incredulous (doubtful) that I would want to speak with her about Thompson.
“Why talk to me? My relationship with George was a transitory (not lasting, temporary) affair. It only lasted for a couple of months. I dumped him over three weeks ago,” she purred.
“What were you doing Monday between 10 am and 8 pm?” I asked.
“If you are asking if I have an alibi (an excusecor explanation), I’m afraid it isn’t a great one. I wasn’t feeling well that day, so I stayed home in bed. My maid came in a couple of times to bring me a cup of tea and a snack.
You can check with her.”
“Oh, I will.”
I’m usually an optimist (a person who looks on the bright side), which is rare for a PI, but I was beginning to doubt whether I’d find Thompson before the playoffs began, and if I did, whether he’d be alive. I was going to have to take decisive (definite, clear) steps to track him down. I needed to interview his teammates one by one starting with the first baseman Hernandez. It was widely known that he and Thompson had a strong aversion to each other. It was going to be a long day.
