This 28-ton Kite Provides 1.2MW of Power

- Adam Clare Leave a comment

One of bizarre criticisms of solar power is that it only works when the sun hits them which means some areas are hesitant to install large solar arrays (honestly, this criticism is so strange since energy use is highest during daytime). Lunar energy, on the other hand, works all day and is very easy to predict which is why using the moon to provide power is ganging interest. This lunar power is captured through tidal flows, has the moon moves water on Earth we can capture that energy by creating machines that spin turbines using the passing water. That’s exactly what Minesto has done with their underwater kite. Traditional tidal power sources are stationary whereas the Minesto Dragon 12 is only tethered to the sea floor so it can ride underwater currents to produce more power than a stationary tidal generator.

The Dragon 12, like other tidal devices, will be more effective in some places than others – and Denmark’s Faroe Islands, an archipelago in the chilly North Atlantic between Scotland and Iceland, offer ideal conditions. Home to about 55,000 people and more than a million puffins, the Faroe Islands funnel tidal currents through a number of slim channels. This accelerates the water significantly, and thus increases the energy that devices like the Dragon 12 can harvest.

“This is a big day for Minesto,” said Dr Martin Edlund, CEO of Minesto, in a press release. “We have reached the most significant milestone in the history of the company by producing electricity to the grid with our mega-watt scale powerplant. We are both proud and happy and more than ever look forward to the journey ahead … The competitiveness of the Dragon 12 is straight to the point; it’s powerful, cost-effective and feeds predictable electricity to the grid.”

Improve Your Mental Health by Ignoring Celebrities

Are you interested in the comings and goings of the celebrity set? If so, you may want to put down your mobile and go touch grass. Researchers have found a direct connection between mental health and the worshipping of celebrities, as in people not doing so well will tend to follow celebrity news more closely than others. The solution to this is to reduce your use of social media and reflect on what is really bothering you. Does this mean that anybody interested in celebrities is not doing well? Of course not, just if you find yourself preoccupied with the onslaught of information from celebrities you may want to take a break.

The Absorption-addiction model suggests that people worship celebrities to compensate for some personal or social defects, so poor mental state is related to celebrity worship. The current study aimed to explore the underlying mechanisms influencing celebrity worship. A total of 1,147 participants (aged 19–26 years) completed online questionnaires to assess social anxiety, mobile phone dependence, parental income and celebrity worship. Results showed that: (1) social anxiety, socioeconomic status (SES) and celebrity worship were positively correlated; (2) Social anxiety affected celebrity worship through mobile phone dependence; (3) SES played a moderating role in the mediation model. At higher levels of SES, individuals with high social anxiety showed reduced dependence on mobile phones. These findings highlight the importance of mobile phone dependence and family SES in celebrity worship. Additionally, the findings demonstrated that females are more likely to pay attention to celebrities, but the greater SES and reduced mobile phone dependence can mitigate their celebrity addiction.

Cool Cities Have Botanical Gardens

If you live near a park you know that even a small amount of nature can cool the local environment, and you know that the bigger the park the more cool it is. In terms of a land-to-cooling-effect ratio certain types of parks are more efficient than others with the clear winner being a botanical garden. A simple playground with some trees can cool the local area by 2.9 degrees, a green roof can cool areas by 4.1 degrees, botanical gardens reduce outdoor temperature by 4.9 degrees! Any natural spaces can cool your neighbourhood so this summer get out there, plant some plants, and make your city a cooler place.

From a pool of more than 27,000 research papers, the researchers selected 202 for meta-analysis based on a number of urban green-blue-grey infrastructure categories – including parks, engineered greening projects, wetlands, green walls, parks and botanical gardens.

Trees and plants, for example, help reduce heat by reducing the amount of direct sunlight reaching the ground, while also releasing moisture into the air. Water bodies cool the surrounding environment via “evapotranspiration, shading, the albedo effect, groundwater recharge and temperature buffering” and could also serve as heatsinks, cooling during daylight hours and offering warming potential at night. Green roofs and walls not only help insulate buildings, but also reduce heat absorption, and vegetation can serve as windbreaks for natural ventilation.

eBikes are Killing the Oil Industry

- Adam Clare Leave a comment

This Earth Day it’s good to reflect on one’s own love for the planet Earth. If you want to express your love and appreciation for this ball of rock and air that orbits then Sun then you should ride a bike everyday. If an ordinary bike isn’t your style then you may want to consider an ebike. The future of our built environment will be about two wheels instead of four, and this can’t happen too enough. Thankfully the rise of ebikes is bringing us that future by getting people to ditch their lethal four wheel machines for better two wheeled solutions. Indeed, the oil industry may come to end sooner than projected because ebikes are lowering demand for gasoline!

If taken up, electric micromobility can cut urban emissions. A study of e-scooter riders in the United Kingdom found these trips produced up to 45 percent less carbon dioxide than alternatives.

US researchers estimate that if e-bike trips expanded to 11 percent of all vehicle trips, transport emissions would fall by about 7 percent.

As petrol prices increase and battery prices fall, the cheaper running costs of electric vehicles and even cheaper running costs of electric mopeds, bikes, and scooters will keep eating away at the demand for oil.

Global oil demand is now projected to peak in 2028 at 105.7 million barrels per day—and then begin to fall, according to the International Energy Agency.

Floating Flowers Clean Pollution in Waterways

- Adam Clare Leave a comment

Industrial farming, golf courses, and some industries all contribute an incredible amount of nutrient runoff that enters our waterways. This influx of unexpected nutrients can cause algae blooms and otherwise damage the local ecosystem. To combat this damage from runoff a team from the Florida International University created a floating platform that allows flowers to grow while not flooding out their root systems. The flowers they have chosen to grow are ones that are in demand so they can be sold commercially to fund more floating flowers. This is a novel idea that looks promising and they are already looking to expand the project.

We floated 4-by-6-foot (1.2-by-1.8-meter) mats of inexpensive polyethylene foam called Beemats in 620-gallon (2,300-liter) outdoor test tanks that mirrored water conditions of nearby polluted waterways. Into the mats, we transplanted flower seedlings, including zinnias, sunflowers, and giant marigolds. The polluted tank water was rich in nutrients, eliminating the need for any fertilizer. As the seedlings matured into plants over 12 weeks, we tracked the tanks’ improving water quality.

Encouraged by the success of the marigolds in our tanks, we moved our trials to the nearby canals of Coral Gables and Little River. We anchored the floating platforms with 50-pound (22.7-kilogram) weights and also tied them to shore for extra stability. No alterations to the landscape were needed, making the process simple and doable.
