It uses
solar cells and a Peltier cooler to condense
water. I've seen a diagram of it before. If you look at the
photo in the link you'll see it has
solar cells on each side. Small ones at that.. When riding the bike the legs will shade the solar cells.
I suspect the 1/2 liter/hr may be a bit of
marketing hype. Probably more like 1-2 oz per hour in high humidity areas, as most of the time one side's solar cell or both would be shaded.
