Mitsubishi Power has completed its renovation of the Otake geothermal power plant in Oita Prefecture, Japan. The company worked under an EPC contract, together with Mitsubishi Power Industries and Mitsubishi Electric installing a new turbine increasing the plants capacity to 14.5 MW.

Mitsubishi Power, a major subsidiary of Mitsubishi Heavy Industries (MHI) Group, has today announced having completed its renovation of the Otake Geothermal Power Station (Kokonoe-machi, Oita Prefecture) operated by Kyushu Electric Power Company. Commercial operation of the renovated facility began in October 2020. The stable electric power supply generated by the highly efficient and reliable steam turbine installed as part of this renovation project will curb CO2 emissions, and contribute to a decarbonized economy.

This renovation project was conducted under an engineering, procurement and construction (EPC) contract by a joint venture comprising Mitsubishi Power, which supplied the steam turbine, Mitsubishi Power Industries Co., Ltd., which handled the supply and installation of auxiliary equipment, and Mitsubishi Electric Corporation, which supplied the generator and electrical facilities.

The power generation system utilizes a “double flash and dual pressure” method, the first of its type in Japan. This allows for stable operation of the steam well and efficient use of geothermal resources, and has increased the power output by two megawatts (MW) compared to the previous facility, to 14.5MW. Construction was completed two months ahead of schedule from the plan when work began in May 2019, allowing for the start of commercial operation in October.

In the double flash and dual pressure method, high pressure primary steam from a powerful production well, and low-pressure secondary steam from a weak production well, are supplied to the steam turbine. Steam is further obtained by lowering the pressure of the hot water extracted from the

Mitsubishi Power Completes Renovation of Generating Facilities at Otake Geothermal Power Station

YOKOHAMA, Japan, Oct 5, 2020 – (JCN Newswire) – Mitsubishi Power, a major subsidiary of Mitsubishi Heavy Industries (MHI) Group, has completed its renovation of the Otake Geothermal Power Station (Kokonoe-machi, Oita Prefecture) operated by Kyushu Electric Power Company.

In the double flash and dual pressure method, high pressure primary steam from a powerful production well, and low-pressure secondary steam from a weak production well, are supplied to the steam turbine. Steam is further obtained by lowering the pressure of the hot water extracted from the primary steam, which is then used as secondary steam.

Geothermal energy utilizes the heat energy of the magma chamber inside the earth, and because no combustion takes place above ground, little CO2 is emitted into the atmosphere, making it an effective method of power generation for

Fairbanks Museum gets solar panels, EV charging station, with more improvements coming

It seems written in the stars that Vermont’s planetarium would go solar.

Due to the closure of schools because of COVID-19, Fairbanks Museum and Planetarium has ramped up online classes for students and can be toured virtually through vermontartonline.org.

The Fairbanks Museum & Planetarium in St. Johnsbury received a shipment of solar panels from Sun Common for a solar canopy to be erected in the parking lot.

The museum will also get an electric vehicle charging station. For Burlington museum goers, the trip from ECHO Leahy Center in downtown Burlington to the Fairbanks Museum & Planetarium is 76.1 miles, roughly an hour and a half drive.

In a social media post, the museum said the effort is “part of our ongoing commitment to lightening the Museum’s environmental footprint.”

Many museums have struggled during the closure due to the pandemic and have only recently begun to allow visitors back into their properties. As a result, some have put major projects on hold, but the Fairbanks Museum & Planetarium is an exception. 

An outdoor greenhouse learning space is in the works. It is designed to allow adequate air flow ventilation helpful in preventing the spread of airborne viruses like COVID-19. The space is expected to be heated so classes can continue to meet there after the weather turns colder. 

The museum is also planning its first major expansion in 125 years of the historic, Victorian property. The museum has raised more than $600,000 and is waiting to hear if it will be awarded a $2 million grant for the project.

The annex would be a 6,000 square feet, 3-story addition housing hands-on meteorology and astronomy exhibits. There would be ground level access, including an elevator allowing access to the balcony, which houses much of the center’s collection. This

Space Station bathroom renovation launching on next cargo supply run

It’s a home makeover but 200 miles above Earth: The next resupply delivery mission to the International Space Station will include a new re-designed commode for the astronauts.

A cargo re-supply launch is scheduled to liftoff on a Northrop Grumman Antares rocket Sept. 29 from NASA’s Wallops Island Flight Facility carrying supplies for the astronauts, research, hardware and a marketing experiment for the makeup company Estee Lauder.

Loaded up among nearly 8,000 pounds of supplies, the Northrop Grumman’s Cygnus cargo spacecraft will also deliver a new “Universal Waste Management System,” also known as a space toilet, to the floating laboratory in space and home to astronauts 365 days a year.

The system actually has two important purposes on the ISS. Outside the bathroom needs, it also cleans water to be used again by the astronaut

“We recycle about 90% of all water-based liquids on the space station, including urine and sweat,” NASA astronaut Jessica Meir said in a news release. “What we try to do aboard the space station is mimic elements of Earth’s natural water cycle to reclaim water from the air. And when it comes to our urine on ISS, today’s coffee is tomorrow’s coffee!”

The engineers behind the low-gravity loo spoke about the technology during a press call Thursday with reporters.

The new toilet design will be used on the ISS and for NASA’s second Artemis mission to the moon with astronauts. According to government contracts, NASA awarded contracts totaling more than $23 million to design and build the new system.

The new toilet is 65% smaller and 40% lighter than the current potty on the ISS. It’s about the same size as

Outdoor Kitchens – Designing the Perfect Backyard Cooking Station

Outdoor kitchens are becoming popular these days with everyone wanting to enjoy the great outdoors. Many families enjoy eating outside especially during the summer season. These cooking stations are also great for BBQ parties. Planning for an outdoor living area can sometimes take time because there are several important factors to consider. But once you have your own kitchen outdoors, you will realize that the time, effort and money you put in planning and making your kitchen is worth it.

Considerations

Before remodeling your house to include an outdoor kitchen, it is very important to plan everything first. This is to ensure that you will know exactly what you should, how much you will spend and the end result. The cost is definitely one of the most important factors to consider. How much are you willing to spend for your kitchen design? The price range for an outdoor kitchen usually runs from $ 3,000 to $ 15,000.

Aside from the cost, the design is another crucial factor. You should make sure that your outdoor kitchen does not clash with your house design, backyard landscape or your patio. These kitchens can add to the real estate value of your home so make sure that it blends with the surroundings. You can either hire a professional to design your kitchen or you can also look at picture of popular outdoor living areas for your reference.

Common Designs

There are several outdoor kitchen designs to choose from: L-shaped island, Basic island and U-shaped center. For those with L-shaped designs, there is a separate space for preparing and cooking food. On the other hand, a Basic island design usually includes a sink, a small space for food preparation and a grill. This is usually good for light cooking only. The U-shaped center design divides …
