Ever fascinated living inside a bubble? If yay, then a Spanish firm, R!naldo (that’s not a typo), is geared up to give shape to your dream by erecting Bubble building. Wondering how these concrete bubbles can be eco-friendly? Read on to understand their green characteristics. Made from concrete insulate, these spherical structures can be plastered with enough of real greens to create a garden roof. The large atrium-style inside garden is glass covered. Hence it is warm in the winter while the roof can be opened up in the summer for an all season garden. Roll over for many images as well as info… 
These eco-bubbles are powered by photovoltaic panels that generate sufficient electricity. However in case of shortage of sun’s rays, especially during dark winters, it also can get juiced by the conventional electricity grids. And during summers, when surplus power is produced, thanks to blazing sun, residents can sell their green power to the electricity providing companies. That’s green business, buddy! 
As water is also heated with solar energy, the rainwater and sewage is also recycled appropriately for reusing. Heating and ventilation is provided using heat exchangers and each bubble is energy neutral. The windows and external doors are made from insulating glass while the domes are solar glass to reflect heat. 
Floor is laid from natural material which can be used inside out. It also incorporates appropriately designed kitchen and bathroom units as well as other furniture that blends well with its bubble form. Touted to be the most appropriate form to live in, such structures render the best balance between the needs of people and the natural world by exploiting the available technology. Hey, how much would this kinda green bubbly den cost? I don’t mind trying it out, as it will be a fresh change from the quadrilateral forms of concrete houses.
