Daily Positive (D+), Positive News For A Positive World

Daily Positive (D+) is a not-for-profit media initiative to accumulate, store and publish positive news from all the countries of the world. D+ collects news for each of the 365 days of the year and spreads notable, extraordinary and uplifting information from each culture.

Its mission is to engage global citizens in interesting, thought-provoking dialogue about trending news topics through positive, open concept journalism.

Any registered user of D+ can add and edit news to D+ pages. Each of its news content is curated and researched by international researchers, independent journalists and community contributors.

D+ is also synonymous with different blood groups, such as, A+ and B+. Blood is the essential substance of life as is positivity. D+ aims to ensure the circulation of positivity in the world community at a time when it's most needed.

UNIVERSITY OF UTAH ENGINEERS DEVELOP CHIP THAT CONVERTS WASTED HEAT TO USABLE ENERGY
It’s estimated that as much as two-thirds of energy consumed in the U.S. each year is wasted as heat. Take for example, car engines, laptop computers, cellphones, even refrigerators, that heat up with overuse.

Imagine if you could capture the heat they generate and turn it into more energy.

University of Utah mechanical engineering associate professor Mathieu Francoeur has discovered a way to produce more electricity from heat than thought possible by creating a silicon chip, also known as a “device,” that converts more thermal radiation into electricity. His findings were published in the paper, “A Near-Field Radiative Heat Transfer Device,” in the newest issue of Nature Nanotechnology. (More)
