A solar power company capable of “printing” colourful glass that can generate electricity from the sun’s energy announced a £2m funding boost on Tuesday.
Oxford Photovoltaics, a spin-off from the University of Oxford, said the investment from clean-tech investors MTI Partners will help its solar glass, which can be dyed almost any colour, take a step closer to the commercial market.
“What we say here is rather than attach [solar] photovoltaics to the building, why not make the building the photovoltaics?” Kevin Arthur, the company’s founder and CEO, told the Guardian. “If you decide to build a building out of glass, then you’ve already decided to pay for the glass. If you add this, you’re adding a very small extra cost. [The solar cell treatment] costs no more than 10% of the cost of the facade.”
These generally cost between £600 and £1,000 per square metre, meaning the new cell treatment wouild cost just £60-£100 extra per square metre.
The technology works by adding a layer of transparent solid-state solar cells at most three microns thick to conventional glass, in order to turn around 12% of the solar energy received into low-carbon electricity. The power can then be exported to the national grid or used for the running of a building.
“Within reason we can print any colour, there’s a wide range of dyes, blues and greens and reds and so on.
A Robot Just Operated On A Human Eye for the First Time
From prostate surgery to gallbladder procedures, robots are already mainstays in the operating room. Now, they’re coming for your eyes.
In 2016, researchers from the University of Oxford’s Nuffield Department of Clinical Neurosciences kicked off a clinical trial to test the PRECEYES Surgical System, a robot designed to perform surgery on the retina, the surface at the back of the eyeball. On Monday, they published the results of their robot-assisted eye surgery trial in the journal Nature Biomedical Engineering.
A surgeon uses a joystick to control the mobile arm of the PRECEYES system. Doctors can attach various instruments to the arm, and because the system is robotic, it doesn’t suffer from any of the slight tremors that plague even the most steady-handed of humans.
For their trial, the researchers enlisted 12 patients that each needed a membrane removed from their retina — a fairly routine procedure, the study authors note. Doctors performed six of their surgeries the traditional way, while each of the others underwent a robot-assisted eye surgery.
The surgeries start with a tiny incision just above the pupil through which the surgeon inserts a flashlight. For the robotic version, the surgeon inserts the robot through an incision less than 1 mm in diameter, a bit below the pupil. It separates the membrane from the retina, then removes the membrane from the eye, exiting through the same hole it entered. In the surgeries conducted without the robot, the surgeon does this manually, using microsurgical instruments while looking through an operating microscope.
All 12 surgeries were successful; in some cases, the robot made the surgeon even more effective than usual, according to an Oxford press release. In a second phase of the trial, surgeons used the robot on three patients to dissolve under-retina hemorrhages that could have led to vision loss. Those surgeries were successful, too.
A robot-assisted eye surgery did take about three times as long as a traditional one, but trial leader Robert MacLaren told New Scientist that was just because the surgeons were unfamiliar with the robot and moved slowly out of caution.
Now that the researchers have evidence that they can use PRECEYES for routine procedures, they’re turning their attention to far more difficult surgeries — maybe even ones that are currently impossible.
“Our next step will be to use the robotic surgical device for precise and minimally traumatic delivery of a gene therapy to the retina, which will be another first-in-man achievement and is set to commence in early 2019,” MacLaren said in the press release.
While doctors can already perform that operation on patients who aren’t able to see at all, their hands aren’t reliable enough to pinpoint specific spots on the retina for patients who still have some vision. MacLaren told New Scientist that PRECEYES might also allow surgeons to directly unblock blood vessels or inject treatments directly into patients’ optic nerves — two operations that are currently impossible.
PRECEYES is one of several robot surgeons in development, and while they generally may not work as quickly as their human counterparts, their precision will reduce the risk and open new doors to different types of surgery never before possible.
The Damaging Effects Of 5G WiFi On Your Health
Wireless radiation is a huge health problem that continues to be ignored and another opportunity for us to gaze into the past of similar occurrences and learn from our mistakes. Take tobacco for example, at one time in history you were considered a fool and ‘crazy’ for speaking up against the big tobacco companies and letting people know that cigarettes compromise our health. Today, science has spoken, and it has spoken for a long time, despite what the corporations put out into the public and the “science” they used to approve these things in the first place.
There doesn’t seem to be much more of a difference between communication companies that sell and manufacture wireless products and services, which, according to hundreds of scientists and countless amounts of publications, are urging authorities to pay closer attention to what wireless radiation is doing to human health.
This is one of the multiple examples where corporate control rules and dictates government policy, policies that favour big corporations at the behest of planet Earth and the rest of the human population. But it’s more so apparent in North America.
In Europe, multiple countries have restrictions on WiFi and have pointed out some disturbing things. France passed a law in 2015 banning WiFi from all nursery schools, the law states that WiFi must be turned off in all elementary schools when it’s not in use. W wired connection if possible, is preferred. Advertisements directing cell phone use towards young children are banned.
An example from Namibia states quite clearly that current so-called “safety” standards don’t protect citizens from long-term health effects, and that the guidelines governing their use do not guarantee adequate protection against the effects of long-term exposure.
Other countries include Belgium, Spain, Israel, Australia, Italy, Switzerland, Germany, Austria, India, Finland, Cyprus and more.
Why are they saying no to WiFi? See for yourself:
You can access hundreds of these scientific papers and read more here, just click on the science section and under each heading, there are links directly to the research. If you click on the drop-down tab, a list of scientific references as documentation appears.
At the same time, we are the ones using this technology. It’s becoming so useful, and so easy to just rely on the corporation like we do with everything else. How ironic is it that we raise money and advocate for cancer, yet support the very things that are contributing to it, on grande scales?
Millions of children and adults in schools around the world spend significant amounts of time around wireless devices and Wi-Fi. Many schools are introducing Bring Your Own Device (BYOD) policies and installing industrial wireless routers for tablets. However, wireless devices expose students and staff to microwave radiation that can impede learning and overall health. Studies have shown that microwave radiation can damage reproductive systems, impact the immune system, alter brain functioning, and may increase cancer risk. Tablets have up to 5 antennae that are constantly emitting short intense bursts of radiation even when not connected to the Internet. Wireless devices in classrooms thus result in multiple sources of wireless radiation exposure. – Environmental Health Trust
The 5G Health Concerns
So, what about 5G? Science already indicates that the current wireless technologies of 2G, 3G and 4G – in use today with our cell phones, computers, and wearable tech. – creates radio frequency exposure which poses a serious health risk to humans, animals and the environment. 5G is the term used to describe the next-generation of mobile networks beyond the 4G LTE mobile networks used today. 5G is intended to be the technology that allows the “Internet of Things” (IOT) to exist and connects all internet connected devices together.
Scientists have been studying the health effects of 5G and wireless radiation and are deeply concerned with their findings and are calling for a stop to the rollout of 5G, as well as a halt to the proposed increase in radio frequency radiation exposure to the public.
Thanks to all of the efforts by various researchers, scientists and more, the world is waking up to this information and it’s actually starting to become talked about within the mainstream. It always seems like such a long process from the point where something is known, to actually mass consensus and action steps being created.
A CBS news report recently emphasized:
The wireless industry is in a race to roll out. The network is supposed to be up to 100 times faster than current data speeds, but it requires cellphone tower equipment to be closer to users than before. Wireless companies in the U.S. say they’ll have to install about 300,000 new antennas – roughly equal to the total number of cell towers built over the past three decades. That’s causing outrage and alarm in some neighbourhoods, as antennas go up around homes.
5G requires the installation of new equipment across the U.S. Every wireless company is working to build its own 5G network. This is worse than cell phone use, and yet, according to government health authorities, “a limited number of studies have shown some evidence of statistical association of cell phone use and brain tumour risks… but most studies have found no association.”
Waiting for high levels of scientific and clinical proof before taking action to prevent well-known risks can lead to very high health and economic costs, as was the case with asbestos, leaded petrol and tobacco.
“Putting it bluntly they are damaging the living cells in our bodies and killing many of us prematurely” (source)
Melissa Arnoldi, who leads AT&T’s efforts, said “if it’s not already in your neighbourhood, it’s coming.” This is quite concerning, she told CBS news that “5G uses high-frequency waves that support faster speeds but don’t travel as far as current wireless frequencies. So instead of relying on large cellphone towers spread far apart, they need “small cell” sites that are much closer together.”
Sometimes I wonder, how is this even allowed to happen? Who are the people which control what type of information with regards to our health gets emphasized, and what doesn’t?
This new 5G equipment is currently being installed in a neighbourhood near you.
I’ll leave you with this TED talk by a Silicon-valley engineer turned technology health advocate, Jeromy Johnson.
You can use a wired connection, which is very fast and in most cases faster than a wireless connection. Minimize your cell phone use, and perhaps look into some devices that may be used to block the biological effects this stuff is, does, and can have on us.
AI is able to identify people through walls

Scientists have used radio signals as well as an artificial intelligence to track individuals through solid walls.
The remarkable new system is able to produce a skeleton-like visualisation of someone moving around behind a wall by using radio waves to build up a basic picture of them.
The technology is so impressive in fact that it can provide a real-time feed of a person’s movements and is even able to identify a specific individual by analyzing their unique gait.
While the system might seem like a major invasion of privacy, for now it is only being used to track and monitor Parkinson’s Disease patients as part of an ongoing medical study.
“We’ve seen that monitoring patients’ walking speed and ability to do basic activities on their own gives healthcare providers a window into their lives that they didn’t have before, which could be meaningful for a whole range of diseases,” said MIT’s Dina Katabi.
In the future, however, restricting its use to only ethical applications may prove rather challenging.
