Our Built Environment: It Takes Energy

submitted by: nsf

Can we rethink the way buildings use energy? John Ochsendorf, an Associate Professor of Civil and Environmental Engineering and Architecture at MIT, is working with his students to change the way buildings are made and how they consume energy.

Nanotechnology: AFM and SEM Imaging of Titanium Dioxide Nanoparticles

submitted by: cranberrylab

This video was made by students in the CHE230X/ME230X: Nanobiotechnology Laboratory Experience course at Worcester Polytechnic Institute. In this video, students demonstrate AFM and SEM imaging of titanium-dioxide-coated surfaces. This work was funded by the National Science Foundation (EEC 0941746).

LIGHT absolutely does NOT exist.

Light is only the electromagnetic waves of HEAT that hit our retinas and what only our BRAINS then define as Light.

Drive Train Innovations for the Next Generation of Wind Turbines

submitted by: RASEIBoulder
Summary: As tax credits expire for wind energy, the ability to compete with established energy sources is critical. All wind turbine manufacturers are examining their next generation turbines with an eye towards reducing their cost, increasing energy production, and improving reliability. Because the drive train accounts for such a large part of the rotor nacelle assembly cost, it has become a prime target for design change. Drive train innovations which reduce cost, increase energy...

Topological Soft Materials for All-Optic Low Energy Photonics

submitted by: RASEIBoulder
The existing infrastructure for managing the flow of information along the photonic pathways and in our computers is in most segments based on electrically encoded information and the transport of electric charges using the electric force. This process is limiting the speed of signal propagation and is costly in terms of energy dissipation. The predicted worldwide energy consumption of data centers for 2050 is approaching the electric energy generated in the European Union in 2010! It is...

Approaches to Evaluating and Improving Lithium-Ion Battery Safety

submitted by: RASEIBoulder
As lithium-ion battery technologies mature, the size and energy of these systems continues to increase for emerging applications in transportation, grid storage, military use and aerospace. In fact, broadening the application space for lithium-ion batteries from the consumer electronics industries to these emerging markets increases their size from 1-50 Wh batteries for smart phones and laptops to >50 kWh for electric vehicles (EVs) and MWh scale for utility storage systems. As these...
