A pizza box sized solar panel in orbit is producing enough electricity to power an iPad, according to a succesful test of the technology by the US Navy.

The Photovoltaic Radiofrequency Antenna Module (PRAM) was launched in May 2020 attached to a drone that loops around the Earth every 90 minutes and is designed to harness light from the sun to convert to electricity.

The 12x12 inch panel is an early experiment for a technology that could one day harness solar radiation from the sun and beam it to anywhere on the Earth.

It is designed to make the best use of light in space, which doesn't have to pass through the atmosphere where it loses energy before reaching the ground.

SPACE-BASED SOLAR POWER (SBSP)

The idea of Space-Based Solar Power stations have been around since 1941.

Blame the wind? In Texas, fossil fuels have actually played a larger role in leaving millions without power

  Blame the wind? In Texas, fossil fuels have actually played a larger role in leaving millions without power Freezing cold temperatures have caused severe power outages in Texas. A majority of lost generation has been from fossil fuels, not wind. But the main factor is not the source of electricity, but the extreme weather. Visit the Business section of Insider for more stories. It's a popular claim and a powerful image, attracting the attention of conservatives and headline writers of all political persuasions: frozen wind turbines are to blame for Texans losing power and icicles forming their homes during this week's shocking cold spell.

Science fiction writer Isaac Asimov first wrote about them in the short story Reason.

In the story he wrote about a space station that transmits energy collected from the Sun to various planets using microwave beams.

There were a number of concept designs from the 1970s but non were deemed economically viable.

The basic concept involves a space station with a solar array to convert solar energy into electrical energy.

Then it would use a microwave transmitter or laser emitter to transmit the energy to a collector on the Earth.

The UK has joined Japan, China, Russia and the US in pursuing the idea of space based power generation.

As of 2008, Japan made the idea of space solar power a national goal.

Advantages of the technology include the fact it is always solar noon in space with a full Sun.

Collecting surfaces could also receive more intense sunlight than on Earth.

However they would be large satellites, costing a lot of money to launch - although launches have become cheaper thanks to commercial firms.

  Fact Check: Did Wealthy Areas Around Dallas Not Experience Rolling Power Outages? While millions of Texans are without power in their homes due to a winter storm, some social media users allege that a few wealthy areas around Dallas have not been affected by controlled outages.The effects have been widely shared on social media by those who have lost power. One user tweeted an image of icicles hanging from their apartment ceiling fan on Monday.

'To our knowledge, this experiment is the first test in orbit of hardware designed specifically for solar power satellites, which could play a revolutionary role in our energy future,' said Paul Jaffe, PRAM principal investigator.

'Some visions have space solar matching or exceeding the largest power plants today - multiple gigawatts - so enough for a city,' he told CNN.

While this test technology can't 'beam power' to the planet below, future versions could do just that - as the technology has already been shown to work.

'The unique advantage the solar power satellites have over any other source of power is this global transmissibility,' Jaffe said. 'You can send power to Chicago and a fraction of a second later, if you needed, send it instead to London or Brasilia.'

The use of solar energy to operate satellites began at the start of the space age with Vanguard I, the first satellite to have solar cells.

The concept of using solar panels in space, where the energy levels are higher, then beaming that power to the Earth isn't a new concept.

It's an idea first conjured by science-fiction writer Isaac Asimov in 1941 in his science fiction short story Reason where it was revealed a station a mile across was used as an 'energy converter' to gather sunlight and beam it across the solar system.

  Fact Check: Did Biden Rescind Trump Order Prohibiting Chinese Influence on US Power Grid? With power failures causing devastation across Texas, many people began questioning the integrity of the United States' energy supply. Some accused Biden of handing over the country's power grid to the Chinese in an executive order signed in January.Some critics of President Joe Biden are pointing to a section in one of his January executive orders that address a President Donald Trump-era bulk-power system security policy.


Gallery: 25 of the most expensive science experiments in human history (Stacker)

Technology, medicine, and biological research have advanced at dizzying rates in the last 100 years. Many concepts that today stand as iconic representations of scientific innovations, such as computers and space travel, simply didn’t exist at the start of the 20th century. Ushering in such remarkable progress required a lot of work—and a lot of funding.  Among the most expensive scientific experiments of all time is the International Thermonuclear Experimental Reactor (ITER), coming in somewhere between $14.3 billion and $17.6 billion. The nuclear fusion project, funded by 35 collaborating nations, should create the world’s largest magnetic fusion device. If it works, the tokamak would prove the usefulness of fusion as a source for carbon-free energy. But the ITER is not alone in the corridors of pricey scientific innovation. Stacker used a variety of sources to curate a gallery of 25 of the most expensive projects at the forefront of scientific research. From gargantuan lasers to deep-sea observatories, these experiments touch on a variety of disciplines—each ambitious in its scope.  Most of these innovations took place in the latter half of the 20th century, with several still in development. Scientific breakthroughs are coming at increasingly faster rates: Forbes in May 2019 published an article highlighting the past two decades alone as sparking unprecedented creativity, productivity, and output. Heading into a new decade, there are high hopes for what innovations the 2020s will bring. Past developments and access to innovative technology offer bright prospects for the future of scientific discovery.  Read on to discover some of the most ambitious scientific experiments, both in the past and now starting to come to light.

Japan, China, Russia, the UK and the US are all pursuing the idea of space based power generation and Japan has it listed as a national goal.

This current experiment focuses on the energy conversion process and resulting thermal performance, a Navy spokesperson said.

The hardware will provide researchers with temperature data, along with its efficiency in energy production that will drive future space solar development.

The point of this study is to determine whether space solar technology can be delivered at an economically viable price-point, the team said.

Jaffe explained that 'building hardware for space is expensive' but that the costs are starting to come down, especially over the past decade.

This module is sat on the highly secretive US' X-37B space plane - in fact the module is the only aspect of the mission widely known - but future versions could be in a geosynchronous orbit around the Earth.

That is a 'high Earth orbit' that allows a satellite to match the rotation of the planet below. usually about 22,230 miles above the equator. It is useful for monitoring weather, communications satellites and even surveillance.

Austria bets on millions of tests to contain Covid-19

  Austria bets on millions of tests to contain Covid-19 While Austria has struggled to contain the second wave of the coronavirus pandemic, it is fast emerging as a world leader in testing as a way to reopen schools and businesses. The small nation with a population of just under nine million tested three million people last week alone, with the mass-testing strategy forming a key plank for getting pupils back into the classroom. Half of those three million tests were administered in schools, where twice-weekly tests have been mandatory since in-person lessons restarted earlier this month.

On the ground the team are testing future versions to ensure they can still operate under intense heat likely found 22,000 miles from the Earth.

'The next logical step is to scale it up to a larger area that collects more sunlight, that converts more into microwaves,' Jaffe said.

Once they have a panel that can operate at heat in high orbit, they will begin working on a version that can send the collected energy back to Earth.

That means finding a way to control the destination and microwave beam so they don't fire it at the wrong target.

A technology called 'retro-directive beam control' allows them to send a pilot signal up from destination antenna on Earth to space as a form of 'targeting control'.

Jaffe told CNN that using this technique would ensure no microwaves were being sent until it was clear the receiver was online and ready to operate.

In a paper published in the IEEE Journal of Microwaves, Jaffe and colleagues examined the feasibility of 'power beaming' and shared some of the results of the early study involving the pizza box-sized experimental solar panel.

In the paper the authors wrote that power beaming can bring electrical power from easy to produce places, to those areas where it is difficult to generate energy.

This could include unmanned aerial vehicles, balloons, remote installations such as forward operating bases or even in industrial applications.

Jaffe and colleagues claim it could also be used as an 'enabling technology' for sixth generation wireless communications due to come online in the next decade.

UK GOVERNMENT BACKS PROJECT TO DEVELOP SPACE POWER PLANT

Solar power stations in space that beam 'emission-free electricity' down to Earth could soon be a reality thanks to a UK government funded project.

Above the Earth there are no clouds and no day or night that could obstruct the sun's ray – making a space solar station a constant zero carbon power source.

The UK government commissioned new research into the concept of space-based solar power (SBSP) stations as a way to meet the Earth's growing energy needs.

The idea is that the stations would capture the Sun's energy that never makes it to Earth and use laser beams to safely send the energy back to Earth.

It's an idea first conjured by science-fiction writer Isaac Asimov in 1941 in his science fiction short story Reason where it was revealed a station a mile across was used as an 'energy converter' to gather sunlight and beam it across the solar system.

The team behind the study will examine three existing SBSP concepts from the US, UK and China with support from the inventors of the UK and US systems.
