my general hostility to renewables is that they're base load power generators like nuclear. but worse at it. they lack reliability like nuclear, which means that you need to have way more peak plants, grid batteries, or the like, to deal with situations where you have high power draw *and* renewable shutdown. i feel like this should be obvious. if you want to go 100% renewable, you need to be working on renewable energy storage and dispatchable generation. whether that's biodiesel turbines or w/e.

Миссия Pathfinder Technology Demonstrator-4 (PTD-4) входит в активную фазу тестирования. Миниатюрный аппарат, который был запущен 16 августа на ракете Falcon 9 в ходе совместной миссии Transporter-11, прошел основные проверки бортовых систем и технической камеры, с помощью которой была сфотографирована Земля. Эта камера будет снимать процесс развертывания экспериментальной солнечной панели, объединенной с антенной - Lightweight Integrated Solar Array and anTenna (LISA-T). В процессе развертывания центральная стрела, уложенная внутрь аппарата, вытянется почти на метр. На ней закреплены плотно свернутые четыре лепестка ультратонких солнечных панелей, которые также выполняют функции антенн. Такие тонкие и легкие панели решают задачу экономии объема и массы в космических аппаратах. Они в три раза более эффективны, чем классические солнечные панели. Миссия PTD-4 должна показать, как работает такая технология в условиях космоса.

Why You Should Oversize Your Solar Array | Cedar Creek Energy

When considering solar energy for your home or business, one might naturally question the value of installing a solar array that exceeds your current energy needs. At Cedar Creek Energy, we advocate for the strategic benefits of oversizing your solar array, as it can lead to significant long-term advantages. Here’s why you should consider this approach and how understanding the DC-AC ratio and solar array size can make a difference.

Understanding the DC-AC Ratio

To grasp the benefits of an oversized solar array, it’s essential to understand the concept of the DC-AC ratio. Solar panels generate direct current (DC) electricity, which is then converted into alternating current (AC) by the solar inverter for use in your home or business. The DC-AC ratio refers to the proportion of the solar array size (DC) compared to the inverter’s capacity (AC).

An ideal DC-AC ratio is typically above 1.0, meaning the solar array generates more DC electricity than the inverter can convert to AC. This may seem counterintuitive—why generate more power than the inverter can handle? The reason lies in optimizing overall energy production. During peak sunlight hours, the array may produce more DC power than the inverter can convert, resulting in a phenomenon known as "clipping." However, this excess energy is not lost but rather managed to maximize production throughout the day.

The Benefits of an Oversized Solar Array

Maximizing Energy Production: By installing a larger solar array, you capture more sunlight, especially during the mornings and evenings when the sun is at a lower angle. While it’s true that some energy may be clipped during peak hours, the overall energy generated across the day is significantly higher. This is due to the larger array producing more energy during off-peak times when your inverter can fully utilize its capacity.

Compensating for Variability: Solar power is inherently variable. Factors like weather conditions, seasonal changes, and even shading can impact energy production. An oversized solar array helps mitigate these fluctuations by ensuring that even on less sunny days, you generate sufficient power to meet your needs. This added capacity provides a buffer against unpredictable energy losses and ensures a more consistent power supply.

Financial Incentives and Savings: Many financial incentives are available for solar energy systems, especially for businesses. Oversizing your solar array can qualify you for additional benefits such as the Federal Investment Tax Credit (ITC) and Production Tax Credit (PTC). Moreover, programs like Xcel Energy’s PV Demand Credit offer extra incentives for businesses that generate substantial amounts of solar power during peak demand hours. By oversizing your system, you can potentially reduce your reliance on grid electricity and lower your overall energy costs.

Long-Term Investment: Although an oversized solar array may involve a higher initial investment, the long-term savings and benefits often outweigh the costs. With greater energy production, you can enjoy reduced utility bills and a quicker return on your investment. Additionally, as energy prices rise, having a larger solar array provides financial stability and protection against future rate increases.

Enhanced System Performance: An oversized system generally operates more efficiently, as it can better handle variations in sunlight and energy demand. This enhanced performance ensures that your solar energy system continues to operate optimally, providing reliable power and maximizing your energy savings over time.

At Cedar Creek Energy, we specialize in designing solar installations that align with your specific needs and goals. By choosing to oversize your solar array, you’re making a strategic investment in your energy future. Our team can help you understand the DC-AC ratio, optimize your solar array size, and take full advantage of available incentives. Get in touch with us today to learn how we can tailor a solar solution that works best for you and your energy needs.

Outpost (1994)

"Scientists in Singapore have broken a long-standing limitation on the ability to generate electricity from flowing water, suggesting that another elemental force of nature could be leveraged for renewable electricity: rain.

With the simplest and smallest scale test setup, the team could power around 12 LED lightbulbs with simulated rain droplets flowing through a tube, but at scale, their method could generate meaningful amounts that could rival rooftop solar arrays.

Singapore experiences significant rainfall throughout the year, averaging 101 inches (2581 millimeters) of precipitation annually. The idea of generating electricity from such falling water is attractive, but the method has long been constrained by a principle called the Debye Length.

Nevertheless, the concept is possible because of a simple physical principle that charged entities on the surface of materials get nudged when they rub together—as true for water droplets as it is for a balloon rubbed against the hair on one’s head.

While this is true, the power values thus generated have been negligible, and electricity from flowing water has been limited to the driving of turbines in hydropower plants.

However, in a study published in the journal ACS Central Science, a team of physicists has found a way to break through the constraints of water’s Debye Length, and generate power from simulated rain.

“Water that falls through a vertical tube generates a substantial amount of electricity by using a specific pattern of water flow: plug flow,” says Siowling Soh, author of the study. “This plug flow pattern could allow rain energy to be harvested for generating clean and renewable electricity.”

The authors write in their study that in existing tests of the power production from water flows, pumps are always used to drive liquid through the small channels. But the pumps require so much energy to run that outputs are limited to miniscule amounts.

Instead, their setup to harness this plug flow pattern was scandalously simple. No moving parts or mechanisms of any kind were required. A simple plastic tube just 2 millimeters in diameter; a large plastic bottle; a small metallic needle. Water coming out of the bottle ran along the needle and bumped into the top section of the tube that had been cut in half, interrupting the water flow and allowing pockets of air to slide down the tube along with the water.

The air was the key to breaking through the limits set by the Debye Length, and key to the feasibility of electricity generation from water. Wires placed at the top of the tube and in the cup harvested the electricity.

The total generation rate of greater than 10% resulted in about 100 watts per square meter of tube. For context, a 100-watt solar panel can power an appliance as large as a blender or ceiling fan, charge a laptop, provide for several light bulbs, or even a Wi-Fi router.

Because the droplet speeds tested were much slower than rain, the researchers suggest that the real thing would provide even more than their tests, which were of course on a microscale."
