Person 1: Hi, have you heard about solar engines?

Person 2: No, I haven't. What are they?

Person 1: Solar engines are devices that use solar energy to generate power. They are becoming increasingly popular as a clean and renewable source of energy.

Person 2: That sounds interesting. How do they work?

Person 1: Solar engines work by converting sunlight into electricity using photovoltaic cells. The cells absorb the sunlight and convert it into direct current (DC) electricity, which can be used to power various devices.

Person 2: Wow, that's amazing. Are there any disadvantages to using solar engines?

Person 1: One disadvantage is that they are dependent on sunlight, so they may not work as well on cloudy days or at night. They also require a significant upfront investment, although the long-term savings can be substantial.

Person 2: I see. Do you think solar engines will become more common in the future?

Person 1: Definitely. As technology continues to improve and the cost of solar panels decreases, more and more people will turn to solar energy as a viable alternative to traditional power sources.

Person 2: Thanks for explaining solar engines to me. I'll definitely look into them more.
