Why the Future of Solar Power Is from Space
Posted by James Christian Smith in categories: solar power, space, sustainability
Over seven decades ago in 1941, Isaac Asimov wrote a short story, “Reason” (PDF), in which energy captured from the sun was transmitted via microwave beams to nearby planets from a space station. Flash forward to today, scientists are looking to make that very science fiction dream a reality for Earth.
There has been tremendous research on space-based solar power (SBSP) or space solar power (SSP) since the mid 20th century. Here is a great timeline of the various international studies and projects related to SBSP.

Brilliant iron molecule could provide cheaper solar energy
Posted by Genevieve Klien in categories: solar power, sustainability
For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity. The results indicate that the iron molecule could replace the more expensive and rarer metals used today.
Some photocatalysts and solar cells are based on a technology that involves molecules containing metals, known as metal complexes. The task of the metal complexes in this context is to absorb solar rays and utilise their energy. The metals in these molecules pose a major problem, however, as they are rare and expensive metals, such as the noble metals ruthenium, osmium and iridium.
“Our results now show that by using advanced molecule design, it is possible to replace the rare metals with iron, which is common in the Earth’s crust and therefore cheap,” says Chemistry Professor Kenneth Wärnmark of Lund University in Sweden.

Study unlocks full potential of ‘supermaterial’ graphene
Posted by Genevieve Klien in categories: computing, physics, solar power, sustainability
New research reveals why the “supermaterial” graphene has not transformed electronics as promised, and shows how to double its performance and finally harness its extraordinary potential.
Graphene is the strongest material ever tested. It’s also flexible, transparent and conducts heat and electricity 10 times better than copper.
After graphene research won the Nobel Prize for Physics in 2010 it was hailed as a transformative material for flexible electronics, more powerful computer chips and solar panels, water filters and bio-sensors. But performance has been mixed and industry adoption slow.

Huge, high-flying ‘pseudo-satellite’ will soon take to the skies
Posted by Genevieve Klien in categories: drones, finance, solar power, sustainability
More than an ordinary aerial drone but not quite a satellite, a huge solar-powered airplane with three tails and wings wider than a jumbo jet’s will soon be taking to the skies.
Odysseus, developed by Boeing subsidiary Aurora Flight Sciences of Manassas, Virginia, is one of the largest unpiloted aircraft ever built — and one of the lightest. It has a 243-foot wingspan but weighs less than a small car, the company says. Its six electrically powered propellers will be driven by energy from hundreds of solar panels that cover the aircraft’s exterior or from banks of rechargeable batteries on board, depending on the available sunlight.
With a top speed of 100 miles an hour, Odysseus won’t be very fast. But it’s designed to soar to altitudes above 60,000 feet and stay aloft for months at a time.
