It all depends on the size, physical fitness and hydration of the person in question, but it’s possible to sweat buckets before heatstroke sets in and we pass out. After all, there are about three million sweat glands on the human body (the highest concentration is on our palms), and the average person aggressively working out perspires about 0.7 to 1.5 liters per hour. Theoretically, if we were attached to a treadmill and pumped full of liquids, it’s possible to keep sweating forever.
Tiny organisms such as algae offer great promise for a clean energy future by creating biofuels or even hydrogen, if only scientists can figure out how to use them in a cost-efficient way. A startup named Joule Unlimited has hit upon a possible solution, with a genetically tailored organism that sweats out its fuel and lives on to continue making more, New York Times reports. The company broke ground recently on a Texas pilot plant that will house the single-cell plant organisms in flat structures resembling solar panels facing the sun.
A sensor that measures electrolyte levels in real-time could help athletes optimize on the go

The Biotex Sensor
Gatorade goes to great lengths to determine if "It" is in you. Sweat patches slapped on Maria Sharapova and Tiger Woods provide before and after snapshots of electrolyte levels and sweat rate. But, what about during competition? Swiss company Biotex is developing a garment with wireless sensors embedded in the lower back to provide real-time values for similar metrics. Hydrophilic and hydrophobic material draws the sweat into flexible sensors just two millimeters thick and a few square centimeters. Data can be stored for future analysis or transmitted to wireless phones or PDAs so athletes know to hit the water fountain before it's too late.
"It's like driving a car around town, if you don't watch your gas gauge it will be too late and you'll be empty," said Project Coordinator Jean Luprano. "You need to know whether to slow down or if you can go faster."
Start with water. Add chlorine, sweat and urine. What you get may be a soup of nasty byproducts

Do you smell chlorine when you swim in an indoor pool? Maybe it's not chlorine after all.
Researchers at Purdue University have identified "volatile disinfection byproducts" that can form when chlorine in pool water reacts with sweat and urine. When enough of these byproducts form, they can cause problems for breathing, skin and eyes.
