>>674999>What sort of performance is realistic under more moderate conditions? Could this be worth the weight or is it more meme gear like the biolite?Its a meme /scam
its just far far far to energy inefficient.
compare it to pic related.
This thing is a lot bigger (like half a washing machine)
This thing only Produces ~24L/ a day or 1L /hr of water.
This thing consumes 500 Watts per hour to do so.
This things uses a far superior cooling cycle system.
[Peltiers are like 10 time less efficient compared this liquid based using stuff like R134a]
This thing is bigger and thus has scaling advantages.
so lets calculate.
solar means 12hr of use on a day with perfect sunlight = 12L
make it 10 times smaller to compare it to the bottle system = 1.2L per 12 hours.
therfore 1/10 equal to 50Watts per hour instead of 500W
This leads us to the summary that this system wold produce 100ml water per hour for 50 Watts.
so to get 500 ml water in 10 hour you would need a bit less then 25 Watts for the entire time. looking at amazon this would be a solar panel of 50 cm x 38 cm or 20 x 15 inches big.
BUT this system is 10!!!! fucking times more efficient in heat exchange and condensation then the Peltiers systems used in the bottle. Which once their heat sink gets warm will lose even more efficiency!
So its actually of 10 these solar panel because of the Peltiers inefficiency
Also this is under the products best conditions 40°c and upwards of 90% humidity... sooo like in the fucking rain Forrest
TL:dr i am very very skeptical of the claims, compared to current technology it doesn't add up in the physic department
