Recent tests of a metal-coated graphite power source promise low-cost thrust
and electricity for satellites and other space vehicles. Here's the scenario:
Conventional booster rockets launch the vehicle into low-earth orbit. Deployment of inflatable mirrors then focuses sunlight into a solar engine, heating liquid hydrogen fuel. Escaping through a nozzle, the expanded gas "thrusts" the payload from low-earth to geosynchronous orbit in 30 days or less with twice the efficiency of chemical propulsion systems.
On-orbit, the solar engine stays with the satellite, turning trapped solar heat into electricity. Because it replaces batteries and solar arrays, the "integrated solar upper stage" cuts payload weight and launch costs.

Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
