Discussion Overview

The discussion centers around the interaction between lasers and the ionosphere, exploring the possibility of using lasers to attract stray ions and the potential applications of such interactions. Participants consider theoretical implications and historical references, without reaching a consensus.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the feasibility of attracting stray ions by aiming a laser into the ionosphere.
  • Another participant argues that while lasers can heat and transfer momentum, they do not provide the necessary charge to attract ions, citing various applications of lasers in atmospheric science and communication.
  • A different participant inquires about the possibility of tapping into the electrical potential present within the ionosphere.
  • Another participant seeks clarification on whether the work of Tesla is relevant to the discussion of lasers and the ionosphere.

Areas of Agreement / Disagreement

Participants express differing views on the potential of lasers to interact with ions in the ionosphere, with no consensus reached on the feasibility or implications of such interactions.

Contextual Notes

Participants do not fully explore the assumptions behind the proposed interactions or the specific definitions of terms like "attract" and "tap into," leaving some aspects of the discussion unresolved.

Is it possible to attract stray ions by aiming a laser upwards into the ionosphere?
 
Science news on Phys.org
A laser can heat an object, transfer momentum to an object, interfere with similar sources and disseminate information, but not provide the charge needed to attract ions. Lasers are shone upwards to help reduce of atmospheric diffraction for ground-based telescopes, to measure the distance to the moon, enable earth-based gravitational interferometry, and communicate with satellites.
 
Is it possible to somehow tap into the electrical potential present within the ionosphere?
 
Can someone knowledgeable explain whether the work of Tesla applies here?
