Transparent solar collector to turn skyscrapers into power plants

We may soon be able to create electricity using the screens of our phones, windows in buildings and any other clear surface.

Researchers have created a ‘transparent’ surface that can capture light and convert it into electricity using solar technology.

The team, from Michigan State University, developed organic molecules that are able to take in waves of sunlight which are not visible to the human eye.

It is the first time that a transparent solar concentrator has been created.

Richard Lunt who worked on the research, said that the unique nature of the transparency means we may be able to incorporate it into our everyday lives and create energy from clear surfaces.

“It opens a lot of area to deploy solar energy in a non-intrusive way,” Lunt said. “It can be used on tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader. Ultimately we want to make solar harvesting surfaces that you do not even know are there.”

As the materials used do not absorb or emit any light that can be seen by the human eye, this means they appear transparent when we look at them.

Instead they rely on infrared light, which is guided to the edge of the material where it is converted to electricity by solar cells.

“No one wants to sit behind colored glass,” explained Lunt. “It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent.

“We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then ‘glow’ at another wavelength in the infrared.”

However the future for the technology isn’t yet crystal clear as work needs to be done on improving the energy-producing efficiency.

Currently its solar conversion rate lies close to one percent, but the researchers believe they will be able to get it close to five percent when everything has been fully optimised.

At present coloured variations of the concentrator have efficiency levels of around seven percent.

Russia announces testing of country-wide drone control network, paving way for commercial boom

Roscosmos, the Russian space agency, has announced that it will begin testing a vast drone control network that will run across the nation.

The network, which is based on the country’s extensive existing satellite system, will allow small UAVs to safely operate in massive numbers within Russian airspace.

Once established, it will likely lead to an explosion in the commercial use of drones in the country, with drone deliveries in particular becoming viable on an unprecedented scale.

The announcement was made at Navitech 2017 in Moscow yesterday by experts from Russian Space Systems, a space hardware company owned by Roscosmos. Outlining the details of the system, they said that testing would begin this year, but did not provide a precise date for its start.

Each drone in the network will follow a route determined by the system, with ground-based infrastructure continuously receiving real-time data about its location and flight parameters.

This will immediately be processed and disseminated across the network, to ensure that large numbers of drones can be safely flown at any time, without interfering with both each other and traditional airspace traffic.

The network will not require the establishment of major new infrastructure, as all data will be transmitted through a combination of existing systems: FM transmitters, the country’s established cellular communication systems and GLONASS, Russia’s global satellite navigation system, which has provided 100% coverage of the country since 2011.

The system will also provide real-time data about no-fly zones, allowing routes to be adjusted immediately in response to changing information, and will offer a “platform of integrated applications” to UAV operators, content providers and insurance companies.

Roscosmos believes that the system will significantly reduce operating costs for drone owners by limiting the risks involved with running a commercial drone operation, as well as creating the conditions for new industries to emerge.

Among the industries the space agency expects to blossom through the adoption of the network are drone insurance, cloud software that would increase the capabilities of drones and what it calls “convenient services” – a term that likely refers to drone deliveries.

If the platform does deliver on this hope, it is likely Russia would become the first country with an extensive drone delivery network, realising a dream that was first brought to prominence by Amazon back in 2013. However, the US-based company is unlikely to become the main player in the Russian market, having as yet shown little interest in the country for its Prime Air operations.

As with many countries, drone deliveries are currently a rare occurrence in Russia, with notable exceptions including DoDo Pizza, a Syktyvkar-based company that began delivering pizzas to local residents back in 2014.

NFL players’ union signs historic deal that will enable players to sell their own performance data and make them “healthier and wealthier”

The NFL players association (NFLPA) has signed a landmark deal with human performance company WHOOP that will give players access to, ownership of and the option to sell their individual health data.

All current and future NFL players will be issued with a WHOOP Strap 2.0, which allows them to, without interference from their clubs, monitor their own performance, recovery and sleep.

WHOOP’s strap contains five sensors that measure data 100 times per second and automatically transmit it to accompanying mobile and web apps. WHOOP has also developed a Team Dashboard, which it says has “27 levels of privacy to ensure sharing data is completely secure and comfortable for all parties involved”.

“Our mission at WHOOP is to empower athletes. This partnership with the NFLPA is truly the first of its kind in that athletes will finally become both healthier and wealthier by collecting, controlling, and ultimately having the ability to sell their own health and performance data,” said Will Ahmed, founder and CEO at WHOOP.

“We applaud the NFLPA’s vision and share its commitment to work with athletes to better monitor their recovery and enable longer careers.”

The partnership between the NFLPA and WHOOP is the first of its kind and was secured through the OneTeam Collective, which is an initiative designed to give companies like WHOOP the opportunity to leverage the NFLPA’s exclusive player rights.

WHOOP has hinted at seeking further partnerships with players’ unions in future.

In addition to owning their own data, as part of the agreement NFL players can design custom licensed bands for the WHOOP Strap, which will be made available commercially and allow players to further monetise the arrangement between the two parties.

“Every day, NFL players produce data that can translate into physiological and financial opportunities. We see partnering with WHOOP as the first step in harnessing this exciting technology,” said Ahmad Nassar, President of NFL Players Inc.

“We are excited to have WHOOP and its innovative, holistic monitoring technology serve as our first OneTeam Collective deal. Together, we’re paving the way towards a new frontier where athletes are empowered by data.”

Along with the commercial opportunities WHOOP will offer players, the partnership also promises to help players optimise training and recovery, improve performance and reduce injuries.

The NFLPA and WHOOP will both study the effects travel, sleep, scheduling and injuries have on recovery and generate reports for players aimed at boosting athletic performance.

“WHOOP and the NFLPA are putting the power of data directly in the players’ hands. I want to recover faster, avoid injuries, and have a longer career. This partnership has the potential to contribute to my health, which is imperative to my career in football,” said Russell Okung of the Los Angeles Chargers.
