With a monthly rent of 1900 yuan ($278) for two rooms, these luxury apartments are furnished with soft beds and come with a communal kitchen and solar-powered heater. One unit has been rented out to a musician couple.
Though currently seeing a loss on his investment, Huang is not concerned about profit.
"Because I'm a scientist, not a businessman, I wanted to demonstrate first my technical skills by constructing these capsule apartments," Huang told ABC News.
"In the beginning, I had trouble finding tenants, but once the apartments received so much media attention, all eight were rented out. I was contacted by reporters from China, Japan and America. With all this media attention, I feel like my technical skills have been sufficiently recognized by the public."
Huang's attention now shifts to securing investors. As Huang searches for funding to carry out the next phase of his designs, he faces skeptics who question the capsules' legality and marketability.
In an appearance on Qinghai television station's "One Million Giveaway" that aired on June 6, Huang presented his idea to a five-member panel of judges in the hopes of receiving 200,000 yuan ($29,278) to build 60 capsule apartments and start a company to manage his project.
Huang unveiled a miniature model and exclaimed that it would provide the perfect sleeping quarters even for Yao Ming, the Houston Rockets star from China and who at 7-feet, 6-inches tall is the tallest member of the National Basketball Association. Despite Huang's best efforts, the panel voted 3-2 to deny Huang funding.
Huang maintains that he holds the necessary patents and certificates to build his designs and will keep them within legal requirements. Supporters of Huang's designs in the Chinese blogosphere credit him with providing affordable housing to those in need.
"The capsule apartment helped me out of a financially difficult situation," Zhang told ABC News. "I feel that if they pass the market's test, and if their designs are determined to be safe, then society should support them."
