BrainyRedhead's World

Dr. James E. McClenathan (1922-2007), my Pediatric Cardiac Surgeon, will always be my hero, after all he saved my life...

Frog legs dance when salt is sprinkled on them
A frog’s muscles do not succumb to rigor mortis as quickly as most warm-blooded animals which makes it possible for the muscles to move post-mortem if energy is applied to them some how. This can be done either by cooking (heat/energy) or by salting (ions).Salt,also known as NaCl, can work like electricity because it is made up of ions (Sodium and Chlorine to be exact) and ions carry an electrical charge. In living animals, sodium delivers a signal to cause muscles to contract.
The frog legs in the video are fresh so energy (ATP) is still stored in the cells. When the electrical impulse is applied, the legs contract even though the frog is dead!Of course this doesn’t apply to only frog legs!

Green energy from the bottom of the sea
First we got wind turbines to generate energy and now it seems scientists have found a way to tap the energy force of waves….
The device, pictured above, involves two air chambers: as a wave passes over the top of the first chamber, the pressure inside increases, forcing air through a passageway to the second chamber. Inside the passageway is a turbine, so the passing air is actually what generates the electricity. As the wave continues on, it raises the pressure inside the second chamber, pushing the air back through the turbine — importantly, it is a bidirectional turbine — and back into the first chamber. Another wave, another cycle. Repeat.
Find out here how powerful this device can be.
