Better ovens already exist, such as combi-ovens, but they are all designed for commercial use or extremely high end personal use, and so have 5 figure price tags. It would definitely be cool to see that come down to 3 or 4 figures for reasonable consumer versions (e.g. combi-ovens are designed for cooking multiple sheet pans full of food, that's overkill for home use, so there's an opportunity for cost savings). Definitely an opportunity for crowd funding to get development rolling.
