Go USA! The sentiment didn’t exactly help the U.S. Soccer Team this weekend (still reeling), but that’s not the case for Virgina Tech as the winner of this year’s Solar Decathlon Europe. Its entry, called Lumenhaus, is packed with energy efficiency features like walls that maximize ambient lighting and airflow as well as a substructure that makes transport a breeze. Question is, how many of those innovations will meet with widespread adoption? Nonetheless, kudos!
