The reading material gives three constraint conditions demonstrating that humans can’t make a permanent human presence on Venus. However, the speaker is opposite this opinion with three corresponding reasons, offering a solving method that we can build the presence over 50 kilometers above its surface.

First and foremost, the reading passage pointed out that the atmospheric pressure on Venus’s surface is quite high, nearly more than 90 times greater than that on Earth. Despite this fact, as the speaker says, the pressure in the place of 50 kilometers high is not that great but almost normal pressure on Earth. Therefore, there would be no worry that machines might be crushed and broken as mentioned in the reading passage.

The second condition is the lack of water and oxygen on Venus. This argument is also opposed by the speaker with the solution that we can use chemical materials in Venus’ atmosphere to produce water and oxygen, despite the truth that there are only nitrogen, sulfuric acid and carbon dioxide in its atmosphere.

As for the final problem, which is that Venus could only get a little bit of sunlight, blocked both by the thick clouds and carbon dioxide, the presence in the height of 50 kilometers also makes it not a problem anymore—the height is above the clouds, so it can acquire sunlight both directly from the sun with little reflection and from the clouds’ reflection. Thus, solar power cells can survive and produce even more electricity for humans to use.
