Discussion Overview

The discussion centers around the concept of Air HES (Air Hydroelectric Station), a proposed new type of power plant currently in the research stage. Participants explore the potential for generating green electricity and clean drinking water, as well as the technical challenges and feasibility of the project.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express optimism about Air HES providing a source of green electricity and clean water if experiments succeed.
  • One participant critiques the clarity and correctness of the website's language, suggesting that it undermines the project's credibility.
  • Concerns are raised about the feasibility of the proposed water flow rates, with one participant questioning the estimated speeds and suggesting that flow losses may be higher than anticipated.
  • Another participant proposes conducting experiments with a specific tube length to verify flow rates and recommends using fluid dynamics equations for better estimates.
  • Discussion includes calculations related to the lifting capacity of a hydrogen balloon, with participants referencing external sources to clarify the necessary balloon size for lifting specific weights.
  • One participant points out that the lift provided by hydrogen is lower than initially stated, emphasizing the need for a larger balloon to achieve the desired lift.

Areas of Agreement / Disagreement

Participants express a mix of support and skepticism regarding the Air HES concept. There is disagreement on the technical details, particularly concerning fluid dynamics and the lifting capacity of balloons, indicating that the discussion remains unresolved.

Contextual Notes

Participants reference specific calculations and external sources, but there are unresolved assumptions regarding the technical feasibility of the Air HES and the accuracy of the lifting calculations for hydrogen balloons.

Air HES is air hydroelectric station. It is a new type of power plants which is now in research stage. If the experiments will succeed, people all around the World will get a source of completely green electricity and also clean drinking water (even in deserts and so on).

There is no "above-mentioned Swiss HPS". (You should have an editor find and fix all your errors.)

And 450 mph sounds like a really extraordinary speed for water to be passing through a 3 mm tube over a distance of 2 to 3 kilometers.

I think your flow loses are going to be higher than you've estimated.

I would do an experiment with a 30 foot long, 3 mm tube, and check flow rates before I invested more. Or better yet, find the relevant fluid dynamics equations. They will give you ball park numbers. And best yet, they're free!
 
Balloon 500 m3 raises 500 kg

If you look at this site you balloon would need to be larger.

A balloon containing hydrogen of 500 m3 would lift only about 200 kg from the site.

Have you been looking at the graph for hydrogen? The lift is 1.03 kg/m^3
according to that site.

Since the pressure of air is lower at an altitude, the air won't weigh as much.
You won't need more helium, because that expands as well, but the balloon
itself needs to be bigger
