minus-squarelowspeedchase@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up1·3 months ago I think youre misunderstanding one thing, which is that the ice is a replacement for batteries. No, I understood that. The thermal battery is also far smaller, cheaper, and more robust than a lithium battery and it won’t deteriorate with repeated cycling. The repeated cycling thing is the only advantage I see to this, the ice block will not be smaller than a normal battery array. So while its very niche, it is quite effective for home air conditioning. Is it?
minus-squareMidnight@slrpnk.netlinkfedilinkEnglisharrow-up1·3 months ago Is it? 92kWh/m^3 of energy is a lot of cooling. It’d be hard to not be effective.
minus-squarelowspeedchase@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up1·3 months ago These one ton blocks of ice would provide 12,000 Btu/h of cooling for 24hours. source: https://commons.erau.edu/cgi/viewcontent.cgi?article=3263&context=publication#%3A~%3Atext=These+blocks+of+ice+would%2Cone-ton+block+of+ice. So a block of ice about the size and weight of a car to cool one house… I’m really just not following how any of this is worthy of attention?
minus-squareMidnight@slrpnk.netlinkfedilinkEnglisharrow-up0·3 months ago size and weight of a car blocks of ice measuring 4 ft × 4 ft × 2 ft. This you? Because 32 cubic ft is about the volume of most residential AC units.
minus-squarelowspeedchase@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up1·3 months agolol is that the size of your dwelling? That size (4 ft × 4 ft × 2 ft) get’s you 12k btus which is not enough for any house lol.
