Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.

So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don’t we use them for collecting energy?

The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?

The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.

Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.

We just can’t wait to see more of these roads all over the world in the near future.

The young boy saw me, or rather, he saw the car and quickly ran up to me, eager to sell his bunches of bananas and bags of peanuts. Though he appeared to be about twelve, he seemed to have already known the bitterness of life. “Bananas 300 naira. Peanuts 200 naira.” He said in a low voice. I bargained him down to 200 totals for the fruit and nuts. When he agreed, I handed him a 500 naira bill. He didn’t have change, so I told him not to worry. He said thanks and smiled a row of perfect teeth.

When, two weeks later, I saw the boy again, I was more aware of my position in a society where it’s not that uncommon to see a little boy who should be in school standing on the corner selling fruit in the burning sun. My parents had raised me to be aware of the advantage we had been afforded and the responsibility it brought to us.

I pulled over and rolled down my window. He had a bunch of bananas and a bag of peanuts ready. I waved them away. “What’s up?” I asked him.

“I…I don’t have money to buy books for school.” I reached into my pocket and handed him two fresh 500 naira bills. “Will this help?” I asked. He looked around nervously before taking the money. One thousand naira was a lot of money to someone whose family probably made about 5,000 naira or less each year. “Thank you, sir.” he said. “Thank you very much!”

When driving home, I wondered if my little friend actually used the money for schoolbooks. What if he’s a cheat? And then I wondered why I did it. Did I do it to make myself feel better? Was I using him? Later, I realized that I didn’t know his name or the least bit about him, nor did I think to ask.

Over the next six months, I was busy working in a news agency in northern Nigeria. Sometime after I returned, I went out for a drive. When I was about to pull over, the boy suddenly appeared by my window with a big smile ready on his face.

“Oh, gosh! Long time.”

“Are you in school now?” I asked.

He nodded.

“That’s good,” I said. A silence fell as we looked at each other, and then I realized what he wanted. “Here,” I held out a 500 naira bill. “Take this.” He shook his head and stepped back as if hurt. “What’s wrong?” I asked. “It’s a gift.”

He shook his head again and brought his hand from behind his back. His face shone with sweat. He dropped a bunch of bananas and a bag of peanuts in the front seat before he said, “I’ve been waiting to give these to you.”
