Energy & Electricity in Science : How Is Nuclear Energy Harmful?

Posted by who am I On January - 6 - 2009

Nuclear energy can be harmful when radioactivity is absorbed by cells of the body. Discover how radioactivity can damage bone marrow and red blood cells with information from a science teacher in this free video on nuclear energy and science lessons.

Energy & Electricity in Science : How Does Inertia Work?

Posted by who am I On January - 6 - 2009

Inertia refers to resistance to change or movement, so that the bigger the inertia, the bigger the force needed to be applied to the object. Lear more about inertia as a resistance to changes of movement with information from a science teacher in this free video on mechanics and science lessons.

ABSTRACT
A new ultracapacitor technology from APCT (US-Ukrainian start-up) provides an efficient, low cost means of managing power delivery for applications ranging from hand held devices to hybrid vehicles and power generating systems of all types. When integrated into battery powered devices, the APCT technology can extend battery life by as much as 400%, lowering the cost of batteries and reducing hazardous waste streams. Fast charge/discharge cycling with 95% efficiency improves performance and lowers cost for fuel cell vehicles and hybrid electric automobiles. High energy density and hundreds of thousands of cycles provides critical load leveling…
