The Space Fan in the 20th series of Lego's Collectible Minifigures includes a rocket emblazoned with NASA's logo. (Image credit: Lego)Ever since Lego released spacesuit-clad minifigures in 1978, many of the building brick toy's loyal fans have been space fans and many space fans have become Lego fans. Now, the two fandoms have been captured in one new minifigure.The "Space Fan" is one of 16 limited edition characters being released on Sunday (April 19) as part of the 20th series of Lego Collectible Minifigures.The Space Fan is a female minifigure who displays her passion for both Lego and space with the clothing she wears. Her red ball cap has the word "SPACE" imprinted across its front, with the "A" replaced by a five-pointed star. Her grey and white raglan baseball shirt features an image of the "Space Transport," one of the first Classic Space theme Lego sets released in 1978.Related: Lego's awesome Women of NASA building set in photos The Space Fan even has on a pair of space pants decorated with patches in the shape of a star, a heart and a ringed planet.Her wardrobe aside, though, what really sets the Space Fan apart from being just another spacey-dressed minifigure are her accessories. Included with the figure are the Space Fan's blueprints for building a model rocket, a wrench to help do so and the rocket itself! The red and white booster has four fins, a nose cone and is emblazoned on its side with NASA's logo (affectionately known

Has a concrete floor, try to seal its cracks and holes as much as possible. This will limit the number of paths for the radon to seep into the crawl space.Crawlspace depressurizationCrawl space depressurization is another method used to lower radon levels in the crawl space. This system works by actively venting the crawlspace with the help of a fan. This system removes the radon gas in the space as soon as it forms. However, this is not as efficient as the other methods and has some drawbacks. The main drawback of the system is that it uses electricity. Another is that the negative pressure created by the fan sucks in more radon gas into the crawl space. This system only works if the crawl space and the house’s living areas are perfectly sealed off.Crawl space encapsulationThis is the most popular radon reduction technique used in crawl spaces. In this method, a thick plastic sheet, aka vapor barrier, is used to cover the crawl space floor, this making it air-tight. The ends of the sheet are sealed to the walls of the crawl space. This prevents radon gas from entering the crawl space. Even though the sheet is not 100% impermeable, it offers resistance, so the radon gas chooses other easy paths to escape outside.This method is very effective in radon reduction and costs less than an active mitigation system. If your house had radon levels lower than 4pCi/L, this is a good method to implement for further reduction.Crawl space encapsulation is also effective in reducing the moisture problems in your home. It prevents any soil moisture from passing into the house. In addition, the encapsulation also prevents pests and insects from coming into the house.Sub-membrane depressurization systemIf the radon levels in the house are very high, an active mitigation system is recommended. A sub-membrane depressurization system involves encapsulating the crawl space and then using a radon fan to suck the air out from beneath it.Sub-membrane suction radon system for crawl spacesIn this system, the floor and the crawl space walls are sealed air-tight using a thick vapor barrier. Then an intake pipe connected to a radon fan is inserted through this vapor barrier. The pipe should end just below the vapor barrier, and the plastic sheet should be secured around it to prevent any air from leaking into the crawl space. The other end of the radon fan is connected to a vent pipe that ends above the house’s roofline.When the fan is run, it creates a negative pressure zone under the vapor barrier. This zone acts as a collection point of radon gas. The gas is then sucked by the fan and vented through the radon pipes that reach above the house’s roof.This system is very effective in removing radon levels and works well in homes that had high levels of radon before. However, it is not needed if the house’s level of radon was lower than 4pCi/L.

The fan can be cooler in the first place. Air from the ceiling fan is usually hotter because it’s higher in the room. Common buying factors for this fan choice are noise levels, space, affordability, energy-efficiency, versatility, safety, and quality.You can get more flexibility when it comes to controlling the air flow and fan placement. They also come with an oscillating or swivel feature to help you control where the air goes, and it gives you a larger wind chill effect. You can concentrate the air in one direction, and it can be a very quiet way to cool down the room.10. Table FansYou can get bladeless or traditional table fan models if you choose this ceiling fan alternative. They come in small tower designs or as a traditional round fan, and most offer an oscillating movement. This is more for personal use, and they don’t give you enough airflow to cool the whole room. They usually weigh under 10-pounds, so this makes them very portable.The bladeless models offer greater airflow, are easier to clean, and run quieter. They’re also more energy-efficient, and you can find them in a huge range of costs to fit in virtually any budget. A small ceiling fan alternative in this category can cost as little as $20.11. Tower FansA tower-style fan isn’t usually as forceful or powerful as a pedestal fan, but it does take up less floor space. They’re very portable and lightweight, and this allows you to easily move them from room to room. It’s also more aesthetically pleasing and able to fit with a broad range of design styles. You can choose from bladeless or bladed styles.12. Window Air ConditionersA window AC unit takes up less space in your room, and you usually operate them using a digital display or a
