  • Thank you for taking ten minutes for CNN Student News, I'm Carl Azuz.

  • First up the sun broke through yesterday over South Carolina,

  • a welcome sight to many people there

  • after a rainy weather system parked itself

  • over the state last week and drenched it.

  • It could be awhile before the soaked parts of the southeastern state dry out.

  • Some rivers there which have already flooded

  • might not hit their highest points for another two weeks.

  • This is being described as a thousand year storm.

  • Meaning there is a one in a thousand chance

  • this would happen in any given year.

  • Nature has had to find ways to cope.

  • Experts say fire- ants can band together to create a floating raft

  • like this one until they find dry ground.

  • The effects of the flooding on people are even more visible.

  • Officials in South Carolina waking up to lingering fears

  • that more catastrophic flooding

  • and new dam breaches could be on the way.

  • From the river's standpoint, we haven't hit the worst of it yet.

  • Nine dams failing. Buckling under the pressure of historic rains,

  • some areas seeing more than 20 inches.

  • The deluge to blame for more than a dozen deaths in the Carolinas.

  • Just because the rain stops does not mean that we are out of the woods.

  • This road collapsed in Lugath.

  • Claiming the life of a man driving with a female passenger.

  • The vehicle careening through barricades, she survived.

  • Pulled from the overturned wreckage amid rushing water.

  • In Richville, a chilling rescue of a different kind.

  • Flood waters unearthing caskets from a nearby cemetery.

  • That's somebody's family out there.

  • We gotta show respect. This is respect. We gotta respect the dead.

  • This man risking his own life venturing into waist- deep water

  • pushing a casket to shore. In the hard hit area of downtown Columbia.

  • The Congaree River peaking to the highest its been in decades.

  • Covering interstate roads, leaving homes under water

  • and washing out bridges.

  • Now at least six nearby states sending emergency workers

  • into South Carolina for added flood relief.

  • So far 1, 300 National Guard members are on duty.

  • Crews in Blackhawk helicopters leading state wide rescue efforts.

  • It's sad because people have lost their businesses,

  • they've lost homes and it effected everybody across the board.

  • It did not discriminate.

  • The devastation prompting President Obama

  • to declare South Carolina a major disaster area.

  • Ordering federal aid.

  • A vaccine currently being tested is showing a lot of promise

  • against the deadly ebola virus.

  • The worst outbreak in history started in March of 2014,

  • three countries in West Africa, Guinea, Liberia and Sierra Leone were the hardest hit.

  • And last year at this time, the first cases in the U. S. were being treated.

  • After people who traveled to West Africa or come in contact with those who had,

  • contracted the virus.

  • Now, a new vaccine is inspiring hope in the fight against Ebola.

  • Ebola is one of the deadliest diseases in the world.

  • Certain strains can kill 90 % of those who catch it.

  • More than 11, 000 people have died from the virus.

  • And its infected more than 28, 000.

  • As devastating as this disease is,

  • its also inspired one of the more extraordinary achievements in medical history.

  • During the largest ebola epidemic ever, spanning from Liberia to Atlanta.

  • The World Health Organization set out to develop the first vaccine for ebola.

  • Coordinating a massive international group of scientists

  • and drug companies, the WHO seemingly managed the impossible.

  • Cutting through regulatory red tape,

  • the group collaborated to fast track the vaccine.

  • What usually takes a decade or more, this took just 12 months.

  • We tend to see rapid development from places like Silicone Valley.

  • Tech giants holding all night hack- a- thons to fix a problem.

  • But rarely do we see this type of speed from the medical community.

  • But the hope is that the WHO has provided a blueprint

  • for accelerating drug trials in research.

  • So the medical community can react quickly the next time a killer virus strikes.

  • There are no vaccines for some of the most dangerous pathogens,

  • that spread very quickly through the air. Think SARS.

  • But after Ebola, we may be one step closer to preparing for such an outbreak.

  • We're starting today's call of the roll in the Pine Tree state.

  • That's the nickname for Maine.

  • And from its largest city, Portland,

  • we heard from the Lions of Lincoln Middle School.

  • Not too far from Salt Lake City, Utah,

  • there's a city named American Fork,

  • and we're shouting out to Seagulls today from Dan Peterson School.

  • And in the nation of Myanmar, also known as Burma,

  • it's great to see our viewers at Yangon International School.

  • It's in the city of Yangon.

  • As gas prices have gone lower in the US,

  • it has generally meant lower sales for electric cars.

  • More Americans have been going with gasoline- powered engines.

  • Part of the reason?

  • Most electrics, with exception of the more expensive Tesla brand,

  • don't go that far on a charge.

  • A gas- powered car can drive more than 300 miles on a full tank of gas.

  • Most electrics can't go 100 miles before needing to recharge.

  • What if the roads themselves could charge them? It's practically instinct.

  • The light comes on and you search for the nearest gas station.

  • Every once in awhile panic sets in. But we usually know fuel is close by.

  • The problem? Oil is not sustainable.

  • A solution. Electric, but it has its physical limitations.

  • The biggest challenge right now is what we call range anxiety.

  • It means people are really worried about this new technology

  • and they feel like they`re stranded at some point, right? Battery is empty and they can`t go any further.

  • Right. And that is often the number one reason why they will not buy an electric vehicle.

  • This technology could completely revolutionize that.

  • The technology Klaus is referring to is called dynamic wireless charging.

  • It works just like the wireless internet,

  • but instead of getting you online, it charges your car as you drive.

  • The Oakridge National Laboratory is a transportation testing facility

  • run by the US Government.

  • Their mission is to solve the world's transportation problems,

  • and that means convincing automakers, consumers,

  • and tax payers that it's worth it to rip up America's interstates.

  • How do you retrofit roads to become wireless charging stations?

  • One of the current scenarios is that the coils

  • would actually be embedded in the roadway.

  • So this is the part that would be placed into the roadway

  • or placed in the parking opportunity. So this would embedded in the road?

  • You'd actually have it flush at ground level. Okay.

  • So this one would be on the underside of the vehicle.

  • And as the vehicle drives anywhere,

  • it would be free from any debris or any possible impact.

  • And then this one would be the one that's embedded in the vehicles,

  • or the roadway system. What would be the power source of these pads?

  • Well I've seen different scenario and options play out,

  • and one of those is a solar array.

  • To utilize land that's available next to the roadways as you drive down the freeway.

  • Oakridge isn't the only place experimenting with dynamic wireless charging.

  • At least ten other countries across the globe

  • are toying with using high tech coils in the roadways.

  • The cost for installing these wireless charging stations,

  • what dollar amount are we talking here?

  • If you assume that it costs about $ 2 million per mile to put it into the highway.

  • It would be about $ 80 billion

  • and you would have the entire interstate

  • system equipped with like electrified HOV lanes.

  • And that now enables you to always leave the interstate

  • with a full tank of electricity in your battery. What's the biggest hurdle?

  • I'd say the biggest hurdle is really getting some hardware

  • in different vehicles and showcasing the interoperability of systems

  • and highlighting to the consumers that it's safe and that it's semi- autonomous.

  • There's not a whole lot of interaction.

  • If you're considering an electric vehicle,

  • if there are more opportunities to charge up easily,

  • vehicles can become cheaper because the batteries themselves are a little bit smaller.

  • At Thompson's Farm in Naches, Washington,

  • tis the season for hayrides, tree ripened apples, fresh fried donuts,

  • and firing pumpkins out of a cannon.

  • Farmer John Thompson custom created this uncommon contraption

  • that's become his main attraction.

  • It uses pressurized air to launch pumpkins almost a mile away.

  • He calls it his pride and joy and uses it for target practice,

  • as well as simply proving to the world that some pumpkins actually can fly.

  • If anything can draw a crowd, that cannon.

  • There's no charge to see it, proving there is such a thing as a free lunch.

  • Maybe it stems from the farmer's good nature.

  • Maybe he just does it for the greater gourd.

  • I'm Carl Azuz, we always enjoy a little pun- kin on CNN Student News.
