2 . Last Thursday, the world’s first self-driving, electric container ship made its first trip to Oslo, Norway. The ship’s owners aim to cut pollution by transporting large quantities of products by water on the southern coastal of Norway instead of by truck.
The ship, called the Yara Burkeland, is owned by Yara, a company that makes fertilizer (肥料). The company wanted to develop a zero-emission (零排放的) ship that was completely self-driving. Yara worked with a ship-building company called Vard and the technology company Kongsberg to develop the ship. The company says that in the future everything, including loading and unloading the ship, will be handled completely automatically.
The Yara Birkeland can carry 120 large containers like those pulled by trucks. But the ship is fully electric and is powered by batteries. The company says the ship has roughly as many batteries as 100 electric cars. The electricity that will be used to recharge the batteries is from renewable hydroelectric (水力发电) sources, so there’s no pollution at all.
The Yara Birkeland won’t usually be going to Oslo, and it won’t be traveling far, either. It will travel along a regular route from Yara’s factory in Porsgrunn up to the port in Brevik. By road, that’s a distance of about 14 kilometers. Yara normally uses diesel-powered (柴油动力的) trucks to move fertilizer between these locations.
Now, with the Yara Birkeland moving huge amounts of fertilizer by water, the company expects to suspend 40,000 yearly trips by diesel-powered trucks. That will prevent about one million kilograms of carbon emissions every year.
In the future, as an autonomous ship, the Yara Birkeland is expected to operate without any human involved. Yara plans to spend the next two years improving and testing the ship. But, as with many autonomous cars, the ship will continue to have humans watching over even if it is driving by itself.

9 . Traveling by train can be a romantic way to see the world. Here are some fantastic train trips to add to your travel bucket list.
Qinghai-Tibet Railway
Where it goes: Xining to Lhasa
How long it takes: 20 hours and 55 minutes
Why not start with the world’s highest train ride? The gorgeous 1,215-mile journey only makes seven stops as it passes through four different biological community. Booking between April and November bodes for better weather, though the stunning views of grasslands, wetlands, mountains and deserts are always breathtaking.
Eurostar
Where it goes: London to/ from Paris
How long it takes: Two hours and 15 minutes
Eurostar is a popular way for folks to get from London to Paris, but it has another draw that makes it a great bucket-list train trip. For 20 minutes, you’ll actually be riding 150 feet underwater through the famed English Channel. Trains leave from St. Pancras/King’s Cross in London and arrive in Gare du Nord [ in Paris].
Orient Express
Where it goes: Paris to Istanbul ( original route)
The Orient Express is one of the most famous train journeys in history, with movies and murder- mystery novels undoubtedly adding to its mystery and fascination. You can still ride its original route — all of which is included in a Eurail Global Pass.
Trans-Siberian Railway
Where it goes: Moscow to Vladivostok
How long it takes: Seven days
The Trans-Siberian Railway is another historically famous railroad that should be on your bucket list. It’s also the world’s longest continuous railway, clocking in at 5,772 miles from Moscow to Vladivostok, Russia. Along the way, you’ll pass through eight times zones and have plenty of time to see the beautiful Russian countryside.

10 . When you walk on a sandy beach, it takes more energy than walking down a sidewalk—because the weight of your body pushes into the sand. It turns out that the same thing is true for vehicles driving on roads.
“The weight of the vehicles creates a very shallow indentation in the pavement—and it makes it such that it's continuously driving up a very shallow hill,” said Jeremy Gregory, a scientist at M. I. T...He modeled with his teammates how much energy could be saved-and greenhouse gases avoided—by simply hardening the nation's roads and highways.
And they found that hardening 10 percent of the nation's roads every year could prevent emissions equal to 440 megatons of carbon dioxide over the next 5 decades—that amount is equal to how much CO, you'd spare the planet by keeping a billion barrels of oil in the ground or by growing 7 billion trees for a decade. It reduces 0.5% of projected transportation emissions over that time period.
As for how to harden roads, Gregory says you could combine small amounts of certain fiber with high technology into paving materials. Or you could pave with specially-made concrete, which is harder than ordinary construction materials.
This system could also be a way to shave carbon emissions without some of the usual barriers. “Usually, when it comes to reducing emissions in the transportation department, you're talking about changing policies related to vehicles and also driver behavior, which involves millions and millions of people—as opposed to changing the way we design and preserve our pavements. That's just on the order of thousands of people who are working in transportation agencies.” And when it comes to improving our streets and highways-those agencies are where you might say the rubber meets the road.
