不能使用全天候皆能運作的道路。

are totally cut off for some part of the year.

and they cannot get their goods to market

85 percent of roads are unusable in the wet season.

雨季裏百分之85的道路都是不可用的。

In the U.S. alone, there's more than four million

very expensive to maintain infrastructure,

Can we create a system using today's most advanced technologies

that can allow this part of the world to leapfrog

in the same way they've done with mobile telephones

Many of those nations have excellent telecommunications today

without ever putting copper lines in the ground.

我們能用同樣的方法來處理交通嗎？

Imagine you are in a maternity ward in Mali,

想像你在馬里（非洲國家）的產房，

and have a newborn in need of urgent medication.

Well, you would place a request via mobile phone,

and someone would get the request immediately.

The medication may take days to arrive, though,

We believe we can deliver it within hours

我們相信，利用獨立飛航的工具

with an electric autonomous flying vehicle

This can transport a small payload today, about two kilograms,

over a short distance, about 10 kilometers,

but it's part of a wider network that may cover

同時是一個龐大網絡的一部分，

the entire country, maybe even the entire continent.

大至整個國家，甚至整個大陸。

It's an ultra-flexible, automated logistics network.

它是十分彈性，自動的物流網絡。

It's a network for a transportation of matter.

The first is electric autonomous flying vehicles.

Let's look at each one of those technologies in a bit more detail.

現在，我們詳細地看這些科技。

Eventually, we're going to be using all sorts of vehicles

有朝一日，我們將根據不同的重量和距離

for different payload capacities and different ranges.

今天，我們在用四方的小飛機。

These are able to transport two kilograms

over 10 kilometers in just about 15 minutes.

飛超過10公里運輸2公斤的物資。

Compare this with trying to trespass a bad road

嘗試用車走過凹凸不平的道路，

So they use GPS and other sensors on board

Every vehicle is equipped with an automatic

so these vehicles navigate to those ground stations,

The ground stations are located on safe locations

They secure the most vulnerable part of the mission,

它們鞏固整個任務最脆弱的部分：

They are at known locations on the ground,

so the paths between them are also known,

因此它們中間的路線也是清楚的；

which is very important from a reliability perspective

站在可信性的立場來說，對於整個網絡，

Apart from fulfilling the energy requirements of the vehicles,

commercial hubs where people can take out loads

The last component is the operating system

It monitors weather data from all the ground stations

它掌控來自地下車站的天氣資料，

and optimizes the routes of the vehicles through the system

I want to show you what one of those flights

這是去年夏天我們在海地的航行，
