Stanford Solar Research: Carbon Dioxide Idea to Create Flexible Panels

Click For Summary

Discussion Overview

The discussion revolves around a proposed method for creating flexible solar panels using carbon extracted from carbon dioxide, as an alternative to the carbon sourced from methane. Participants explore the feasibility, energy requirements, and potential benefits of this approach in the context of solar energy production and environmental impact.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests using carbon extracted from carbon dioxide for solar panel production, proposing it as a synergistic solution to both pollution and energy generation.
  • Another participant points out the significant energy requirements for breaking the bonds in carbon dioxide, indicating that the process may not be feasible without substantial energy input.
  • A different viewpoint emphasizes the need for an electricity-based process to separate carbon from oxygen, questioning the practicality of using fusion as a potential energy source for this separation.
  • One participant provides a quantitative perspective on the energy dynamics, noting that the energy required to break carbon-oxygen bonds exceeds the energy gained from forming oxygen-oxygen bonds, suggesting an overall energy deficit in the proposed process.
  • Another participant discusses the inefficiency of the energy conversion process, highlighting that the energy needed to separate carbon from carbon dioxide would require burning significantly more coal than the energy produced.
  • There is a request for clarification regarding the Stanford University research and references to the relevant papers or reports discussing the solar panels.
  • A participant expresses optimism about the concept, suggesting that the energy produced by the solar panels could eventually offset the energy required for their production, though they also raise concerns about cost-effectiveness and efficiency compared to existing technologies.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and efficiency of using carbon dioxide for solar panel production, with no consensus reached on the practicality of the proposed method or its energy implications.

Contextual Notes

Participants highlight the complexities of energy requirements and efficiency in the proposed carbon extraction process, indicating that assumptions about energy sources and conversion efficiencies are critical to the discussion.

A Standord Solar Research Post about a new Solar Membrane Panel, flexible for a wide variety of uses, (clothing rechargers anyone?), offered that the panel design includes deposition of Carbon atoms extracted from Methane.
My concept went to extracting Carbon Atoms from Carbon Dioxide and using them in the panel, while "freeing" the Oxygen atoms into the atmosphere to aid cooling.
If there is nothing wrong with my chemistry, why hasn't that been done? Too difficult?
It sounds like a "two-fer." using a pollutant and global warming component in a new process that is truly synergistic.

It needs energy, quite a lot of energy.
You would generally get this energy by burning C into CO2 in a coal fired power station!
 
You seem to be explaining an origination process, not an extractive/conversion process.
The objective is to separate the Carbon from the O, so that it can be used in the deposit process of manufacturing Solar panels as outlined by Standord U.
If electricity could be used in the process, then the panels would/could generate their own raw supplies, plus help in cooling.
Why not a fusion process?
 
Making bonds gives off energy, breaking bonds takes energy.

To break each C=O bond in CO2 takes about 805kJ/Mol but you only get back about 500kJ/mol to make the O=O bond so overall the reaction takes energy.

This should be obvious by the fact that C+O2 ->CO2 happens in nature but not the other way around.
 
Or looking at it another way: since the reaction is nearly exactly reversible and the power plant and distribution grid is about 1/3 efficient, you need to burn 3x as much coal (carbon) as you get back by using electricity to separate CO2 into its original carbon and oxygen.

What is Standord U? And please provide references for the papers or reports that talk about these panels.

Sounds like quite a smart concept to me. The energy produced by the solar cells could offset the energy needed to make the cells (over a period of time). Ideally this process could then depend on the electricity produced by the solar panels. Solves two problems in one but it's probably not very cost effective and the cells are probably inefficient, if you were going to invest in a power plant, especially since photovoltaic powerplants are more costly than solar thermal ones, you would be more likely to go for the cheaper technology (existing photovoltaic cells) which is already developed and on the market.
