Israeli solar thermal collectors made like honeycombs trap more heat from the sun to heat homes in cold countries like Germany.
Israel is the land of milk and honey –– and solar hot water heaters. Practically every roof in Israel is fitted with a solar thermal collector to warm water for endless hot showers and hot water for the kitchen sink. Taking the idea of solar thermal hot water heaters to the next level is Tigi Solar, a new Israeli company that was inspired by the busy bee.
The inside of Tigi’s solar energy collector looks like a honeycomb. This unique shape helps collect more sun power more efficiently than regular solar collectors –– so efficiently that boiling hot water made from the sun can even be piped in to heat homes.
