J-Innovators:
A Super-Realistic Dinosaur Suit!

Today's Takumi has invented a set of amazing dinosaur suits. They seem so real, and their lifelike movement is the key. There's actually a person inside each suit operating it. The suits may be large-one is 6 meters long and 2.3 meters tall-but their movements are incredibly precise. They can turn 360 degrees, swing their tails around, and close their jaws just inches short of biting you! And this precise motion isn't controlled by fancy, cutting-edge technology-just clever physics. Michelle Yamamoto ventures into the workshop where these dinosaurs are born. You don't want to miss this J-Innovators!

Science News Watch:
The World's Thinnest Solar Battery

Koichi Kitazawa, today's Science Watcher, is a superconductivity specialist, and an expert on everything electrical. He became interested in the development of the world's thinnest and lightest solar battery yet. Only 1.8 microns thick, it is the result of a joint research project done by the University of Tokyo and a university in Australia. How did this research group create the world's thinnest solar battery? Even expert Kitazawa is astounded by how they did it!

The Leading Edge:
Tapping Waste Heat to Produce Electricity

Heat-generating objects are all around us, from personal computers and televisions to cars and factories! This heat represents an enormous amount of energy, but most of it goes unused, a huge waste. Efforts to capture this heat, and generate power from it, are now in the spotlight. One key to these efforts is the Seebeck effect: a phenomenon where a difference in temperature can generate electrical power. We will explain this effect in detail, and introduce research in Japan that is generating thermal power using a related, but different, scientific principle. The fascinating new method that uses this principle generates electricity using electrical insulators. Join us as we investigate the great potential of thermal power generation. It is using everything from industrial waste heat to the heat from our own bodies to create a more eco-friendly future.
