It makes sense that scientists can't think in terms of what works on earth when figuring our what would work on another planet. They need to think in terms of that planet and not yours to figure out how to do things using different resources. I think that it's amazing that these scientists figured out how to use carbon dioxide to power an engine. After reading the article, I wanted to learn more about this engine, what it looks like, and how it works in more detail compared to a regular engine.

Oh, and one last thing, I liked that in the article, the authors used an "s" in place of a "z" in a few of the words. Clearly a hint that the article was written by someone outside of the United States.

As the vast majority of humanity understands as common knowledge, our current methods of electrical production are indisputably flawed, as they have great negative repercussions on our environment. Whenever gasoline, a natural fossil fuel found under the Earth's surface, is refined into electricity, a harmful chemical is released in the form of smog. Due to the Earth having a greenhouse-like Ozone layer, this pollution will remain inside our atmosphere, and will continue to significantly raise global temperatures. This will eventually cause thermal extinction of life as we know it, with only the beings most adapted to torrid weather retaining the capability to survive. This new device, the Leidenfrost Engine, is incredibly innovative, sporting some of the most advanced technologies we have developed to date. However, there is one seemingly impassable conundrum which I can see. The Leidenfrost Engine requires a limitless supply of dry ice, and while this resource is abundant on Mars, it's low gravity will result in a lack of pressure inside the engine. This will effect the heat engine by allowing a fair amount of the dry ice vapor to escape (making it ineffective) and therefore stunting the velocity of the rotors (making it inefficient). In other words, the machine is unusable on Earth due to a lack of dry ice, and will not function correctly on Mars because of it's low mass. Thank you for listening! Please respond with any additional information, replies, or rebuttals!

Researchers have conducted research on the making of a new device using the Leidenfrost effect. Life may exist on Mars, and researchers want to follow through on their hypothesis. The Leidenfrost effect is "a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point." This is commonly seen the same way as if water was boiling in a hot pan. Blocks of dry ice are supposedly supposed to levitate above hot surfaces protected with water vapor. The technique has implications for being used in alien environments. Scientists and researchers say this could help build future power stations on mars.

To add off of Owen's last comment, the author is from the UK provided the fact that he/she spelled vapor as such, "vapour."
