Did you know that vegetables can be tricked into growing in climates they are not accustomed to? Cool climate vegetables like asparagus are now able to be grown in places as hot as Hawaii. In Hawaii marine engineers have been able to actually convince such vegetables that they’re in cooler climates. That way they grow faster and taste better. What these engineers have been using is very simply cold water. How do they use it? They place pipes in the soil and the cold water flows in through and then cools the air. This stimulates plant growth and enables gardeners in tropical climates to grow crops from cooler climates. Also some of these pipes are exposed to the air and they condense moisture and thus irrigate the garden. What’s especially appealing about this process is that nothing damaging to the environment is being used. Another innovative use for cold ocean water is to cool buildings. Engineers believe that, for example, the entire western coast of the United States could be air-conditioned using seawater. We’ll be back to discuss that possibility after this commercial message.
