You could, and someone else suggested water as a storage device. Unfortunately I no longer have the unit so I cannot test it out…

How about feeding the heat into a thermal mass like stacked bricks or rocks and getting heat during the day as well as some residual warmth in the evening?

Based on your initial results, do you think you could get a similar effect from half as many cans? My thought is that if you wanted this thing to run further into the evening (or between sunny times during the day), you could have every other row be cans filled with water instead of letting air through them. You’d get the same effect through the air rows (with maybe slightly less airflow overall), but you’d have some charge left over to keep it going after the sun goes down, or if it dips behind some clouds for an hour or two. Just a thought.
