Well water

Ever had to hand pump a well?  Hard work and a pain sometimes.  All this energy spent working this level to get a small trickle of water.  Obviously a great invention in a dry climate, but eventual the water table will tapped and we must dig deeper and deeper and deeper.  Trees have found another way to do this.  Through process of hydraulic lift, the roots transport water from greater depth to the upward levels of the sediment.  This effect can be great enough to sustain additional plants which lack the same extensive root systems.  The principles for bringing this water up is the same for and pump and the plant, creating a a force of tension which drives the water upward, against the forces of gravity.  We use the pumping action, plants use the tension created by evapotranspiration.  If we could adopt some sort of wicking system coupled to a evaporating cup of water….well maybe not, but something to think about….

I don’t know if anyone has ever heard one of these, but they sound awesome!  Just saw the end off and sand it down, and go to work.  These shells are probably one of the first musical instruments that were used by early humans.  If you want to take a listen, check out this guy Steve Turre, well known trombonist, and conch player.  The sound of these things is amazing, so much better than anything that has been made of brass.  It would amazing for polymer engineers to figure out how the materials in he shells of these mollusks have such amazing resonance.  Plus the picture of this dude on the beach is just awesome!

Ecosysem services has always been something that interest me.  Understanding and utilizing the functions of natural habitats can provide organisms within more hospitable conditions.  This is something we need to increasingly understand and utilize for our own gain.  Natural wetlands function in removal of nutrients and toxic elements as the water moves through the complex assemblege of plants, animals and organisms.  Current water treatment methods do use microorganism to purify waster water, but  the efficiency of these facilities could work better if modelled after these ecosystems..
