Man's Next Migration

Truckbot, a robot with an Android phone for a brain, has been built at a modest cost of just $30. The phone architecture allows Android software programs or apps to control the little tank-like machine.

The Android phone necessarily becomes the brain of the robot needing no external remote control. Due to the Android programming, the robot could “avoid obstacle, recognize faces and voices, pinpoint…

A undiscovered potential within carbon nanotubes has been discovered by scientists to be capable of producing electrical energy proportion to its weight. Thermopower waves create a temperature of 3,000 K from a reactive layer coating on the carbon nanotubes.

The process is said to be able to achieve 100 times greater than an equivalent weight of lithium-ion battery. It uses laser beams to…

Researchers find a new way to use photovoltaic or solar cells adding vertical silicon nanowires. Present solar cells convert solar energy at about 20% efficiency but are only suitable for a large scale deployment.

In an effort to reduce costs in solar electric power, scientists are now focusing on reducing the quantity and quality of silicon being used to create solar cells.…

Remote radio sensors require long-running rechargeable batteries to keep them running. But still, regular maintenance is needed to ensure that the power is stable or if it needs replacement.

Researchers develop new sensors that require no wiring and maintenance for years to come. Siemens call these “energy autarkic radio sensors” which get their energy from their surroundings and only as needed. The…
