The tuxedo seems to have two separate origins. Why the fashion industry came up with the tux and why it hasn't vanished with the top hat, is tough to say. But why penguins evolved into tuxedo-wearing birds is pretty clear: The white belly makes them harder to spot when viewed in water from below against the surface of a sunlit sea and the black back does the same against the dark ocean surface. It's all about tricking predators. The survival of this monochromatic color scheme in all 17 penguin species is a measure of how well it has worked in nature's often-unforgiving game of survival.
Here are 10 other fun facts to know about penguins.
1. Penguins are birds designed by evolution for swimming rather than flying. Their wings have turned into flippers and though they usually walk upright on land, some drop on to their bellies to scoot over ice. Most species cruise underwater at an average speed of 4-7 miles per hour, but the Gentoo can speed up to 22 miles per hour.
2. All penguins live south of the equator. Although we often associate them with Antarctic, they also occur farther north on beaches and rocky shores in coastal South America, the Galapagos Islands, Australia and South Africa.
3. The largest penguin you will ever see trundling around the Antarctic is the emperor, which can stand in excess of 3.5 feet tall and weigh nearly 80 pounds, roughly the weight of two or three Thanksgiving turkeys. The emperor is also the only bird species that nests in the Antarctic during the winter, when temperatures can drop below minus 100 degrees Fahrenheit.
4. The smallest penguin is the little blue or fairy penguin, which grows barely more than two pounds and 16 inches tall and is found in Australia and New Zealand.
5. The largest known penguin of all time is Anthropornis nordenskjoeldi or giant penguin, which lived more than 37 million years ago, stood 5 feet 7 inches tall and weighed 200 pounds. Its rival in size, the New Zealand giant, dates from around 30 million years ago, stood 5 feet tall and weighed close to 130 pounds.
6. Small penguins usually feed at the surface of the sea, rarely diving for more than a couple minutes. The emperor, however, can dive for more than 20 minutes, reaching depths in excess of 1,800 feet to feed on fish, squid, krill and other crustaceans.
7. Penguins can drink sea water. Salt is filtered from the blood by special glands and the salt is secreted from the nasal passages.
8. With the exception of yellow-eyed and Fiordland penguins, these birds are colonial nesters, gathering in breeding groups that range in number from 100 pairs among gentoo penguins to several hundred thousand in the king, macaroni and chinstrap species. In most species, each pair produces two eggs, though emperor and king penguins—the two largest living species—usually lay only one egg. Among emperors, males incubate the eggs, but in all other species mom and dad take turns. The little blue penguin lays the smallest eggs, about 2 ounces and the emperor pops out the largest, which can weigh a full pound.
9. In the Antarctic, penguins have no land predators, though skuas—gull-like, predatory birds—may feed on eggs and hatchlings. Consequently, penguins have no fear of people and may approach to with a few feet of Antarctic visitors. This defenseless behavior might have proved fatal for penguin species, as it did for other flightless birds such as the dodo and the great auk, wiped out centuries ago by ship crews who took them for food. But Antarctic penguins got lucky. Surrounded by dangerously rough seas and harsh climate, the Antarctic proved a penguin haven. No human set foot there until the 1800s.
10. The oldest known penguin species, Waimanu manneringi, was found in New Zealand as a 62-million-year-old fossil. Looking something like a loon, it had short wings designed for diving but not flight.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
