The key component in Nocera and
Kanan's new process is a new catalyst that produces oxygen gas from
water; another catalyst produces valuable hydrogen gas. The new
catalyst consists of cobalt metal, phosphate and an electrode, placed
in water. When electricity — whether from a photovoltaic cell, a wind
turbine or any other source — runs through the electrode, the cobalt
and phosphate form a thin film on the electrode, and oxygen gas is
Combined with another catalyst, such as platinum, that can produce
hydrogen gas from water, the system can duplicate the water splitting
reaction that occurs during photosynthesis.
The new catalyst works at room temperature, in neutral pH water,
and it's easy to set up, Nocera said. "That's why I know this is going
to work. It's so easy to implement," he said.
I hope Mindsensor or Hitech they can build NXT Sensor combo include Compass Sensor,RealTime Clock,Acceleration/Tilt Sensor I think these sensors are important for Robot Navigation. Now I need 3 sensor + 1 port splitter to connect them. It wast a lot of space and the a lot of wire.
Compass Sensor is to set up the Reference Point
Real Time Clock can use to set the Mark Point
Tilt/Acceleration Sensor & Real Time can use to measure distance
A group of scientists at the Delft University of Technology in the
Netherlands have created a small, remote-controlled robot with a camera
attached. The aircraft weighs only .11 ounces and has a four-inch
wingspan. Labeled the DelFly micro air vehicle, the machine flaps its
wings to move around, making it look like a dragonfly.
昨天先把Bluetooth dongle裝上 Notebook 並和NXT 試接 OK 然後把 NXT# Install 到Notebook 內 用ShartpDevelper 2.2 試了一下 除了Com Port name 要重設外 看來還ok. 另外看了一下NXT RobotC有關 Bluetooth Connection 的程式 好像沒那麼容易 這下子有兩個程式要 開發了 PC Side C# BT Data Access & Graphic NXT Side Sensor Data Ouput
