I wonder if the design could benefit from a lense or mirror fixed to it to concentrate flow from the Sun.

The UK is pushing solar power despite having some of the lowest sunlight levels in the world. Northern Britain receives less sunshine than Canada. According to a World Bank solar resource assessment, the UK ranks among the least suitable countries for solar generation, second only to Ireland in Europe. Low sunlight means low output and greater reliance on backup power. Moreover, the UK government has approved solar geoengineering research - experiments designed to dim incoming sunlight. So the policy is this: build solar in a low sunlight country, while exploring ways to block the sun.

NASA’s Artemis II is on the way to the moon after a successful lift-off in Florida. It’s the first crewed mission beyond low-Earth orbit in more than 50 years. So, how long will it take to reach its destination?

Elon Musk: Thanks to Starship, we'll be able to move AI to deep space. “I see a path to Starship cost-per-ton-to-orbit being lower than air flight. That opens up a very wide range of possibilities. The most obvious one I think is actually solar-powered AI satellites. So, to move the AI to orbit and essentially deep space over time, because you can actually access over a billion times more energy from the sun in deep space than you can on Earth. To scale to Kardashev, to make any progress on a Kardashev 2 scale, which is using some non-trivial amount of energy from the sun, you kind of have to do space solar power. You could only beam a tiny amount of that back to Earth or you would melt Earth. Earth actually receives a very, very tiny amount of the sun's energy. I mean, Earth is a tiny dust mote. Earth, to scale with the sun, we look like a little crumb. So, to scale civilization, to be at all relevant on a Kardashev 2 scale, like to even use a millionth of a percent of the Sun's energy, you really have to have your solar power in deep space.” Tesla Shareholder Meeting, November 6, 2025

So did Neil deGrasse Tyson’s mentor, Carl Sagan prefer non-government exploration and colonization of space? A robust and emphatic, yes. But Neil has somehow concluded a private company funding to space is of no financial value and should be done through government programs that has kept humans grounded since Apollo. Neil has done significant damage to himself and popularization of science in general and I am more than disappointed. So I am speaking up. Here are the receipts: Sailing The Seas Of The Cosmic Oceans The Planetary Society’s Solar Sail Launch was a private funded space launch. I know Nevis not only did I donate to make this happen a number of us met with the team to think out the process. Carl Sagan, the renowned astrophysicist, cosmologist, and science communicator, made significant waves in the scientific and space exploration communities when he announced his intention to pursue the development of solar sail technology using private funds in collaboration with Russian spaceflight capabilities. Solar sails, which harness the momentum of photons from sunlight to propel spacecraft, had long been a topic of interest for Sagan, who recognized their potential for enabling long-term, low-cost exploration of the solar system and beyond. The concept of solar sailing dates back to the early 20th century, but it gained public attention during the 1970s and 1980s, thanks in part to Sagan’s advocacy. He often discussed the promise of solar sails in making space exploration more sustainable and accessible. His vision for a solar sail program crystallized in the 1990s, during a period of renewed interest in private-public partnerships and international collaboration in space exploration. Sagan’s announcement marked a major turning point in the movement to make solar sail technology a reality. In the early 1990s, Sagan began to explore the idea of privately funding a solar sail spacecraft. At the time, NASA and other national space agencies were constrained by tight budgets, making it difficult to prioritize experimental technologies like solar sails. Sagan and supporters, proposed that private financing could circumvent these limitations and accelerate progress. Sagan reached out to Russian space agencies, which had decades of expertise in rocketry and a surplus of launch vehicles following the dissolution of the Soviet Union. By 1994, Sagan had partnered with the Planetary Society, an organization he co-founded in 1980, to spearhead the development of a solar sail mission. The project: a lightweight spacecraft equipped with reflective sails that could demonstrate the feasibility of solar propulsion. With funding secured from private donors and philanthropic organizations, the program quickly gained momentum. In parallel, Sagan and his team negotiated with Russian aerospace contractors to secure a launch vehicle. The Russian space program, eager to find new applications for its technology, agreed to provide a converted missile as the launch platform for the solar sail mission. By 1995, initial designs for the solar sail spacecraft had been completed. The spacecraft, later named "Cosmos 1," was designed to use ultra-thin reflective materials to capture the momentum of sunlight. Testing of the sail and deployment mechanisms took place in the mid-1990s. Tragically, Carl Sagan passed away in December 1996, before he could see the project come to fruition. By 1999, construction of the Cosmos 1 spacecraft was completed, and the launch was scheduled to take place in 2001 using a Russian Volna rocket. While the initial launch attempt failed due to a malfunction in the rocket’s booster, the project inspired further advancements in solar sail technology with successful missions by organizations like NASA and JAXA in subsequent years. Carl’s vision lives on with the private funding efforts of Elon Musk. We endeavor to be bold to venture past humanity’s largest mountain on promethean fire. With Godspeed…

NASA’s PUNCH mission (Polarimeter to Unify the Corona and Heliosphere) captured the action from Earth orbit, imaging comet Lemmon every 4 to 8 minutes over three months. PUNCH’s data make up one of the longest and most detailed records ever captured of a comet interacting with the Sun.

$Elon Musk: We’re heading toward a future where human intelligence becomes a microscopic minority—not just on Earth, but across the entire solar system. Best case? Earth-based intelligence only taps into about one billionth of the Sun’s energy. That’s it. Just a fraction of a fraction. Even the total solar energy reaching Earth is roughly half a billionth of the Sun’s output—and that’s already the majority of what we can access today. Now imagine expanding beyond Earth. The moment intelligence scales into the solar system, the gap explodes. Orders of magnitude more energy. Orders of magnitude more intelligence. What exists on Earth today becomes almost negligible in comparison. We’re not just building smarter systems—we’re entering an era where intelligence itself scales with energy. And the solar system has almost unlimited supply. The real question isn’t if this happens… it’s how humanity fits into a world where it’s no longer the dominant form of intelligence.$
