Discussion Overview
The discussion revolves around the cost of liquid helium and liquid nitrogen, with participants inquiring about prices per gallon and the feasibility of purchasing these substances in smaller quantities. The conversation touches on practical considerations related to buying these materials, particularly in non-bulk amounts.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants inquire about the cost of liquid helium and liquid nitrogen, noting that nitrogen is significantly cheaper.
- There is mention of the price of liquid nitrogen being around a dime per gallon, but this is suggested to be based on high-volume manufacturing prices.
- One participant expresses uncertainty about the availability of purchasing small quantities, stating that one cannot easily buy 10 gallons of liquid nitrogen.
- Another participant references a specific case involving a classroom setting where a person had approximately 10 gallons of liquid nitrogen in a tank.
- There is a suggestion that the cost of helium at institutions like MIT could be relevant, although this point is not fully explored.
Areas of Agreement / Disagreement
Participants generally agree that liquid nitrogen is cheaper than liquid helium, but there is uncertainty regarding the actual prices and the feasibility of purchasing small quantities. The discussion remains unresolved regarding specific costs and purchasing options.
Contextual Notes
Participants do not provide specific prices for liquid helium, and there is a lack of clarity on the conditions under which these gases can be purchased in smaller quantities. The discussion also does not establish a clear understanding of the cost variations based on location or supplier.
