Hi Jpdeyst! Addressing insultation in buildings is definitely a key issue and your idea of using microbots is very innovative. In your proposal, it is very clear the benefits of addressing insulation due to lost heating and cooling as well as the impact on the environment and the kind of buildings analysis that will be required. I think your proposal could be much stronger if you include more specifics or details on these microbots. Are there already working prototypes? What has worked or not worked?
