Not even mixed, let alone half-baked:

- BAKE magazine, like the existing DIY magazine MAKE, only with Halfbakery contents instead of real projects

- Battery station at each gas [petrol] station: 100% electric (non-hybrid) vehicles are first redesigned so a robot arm can easily swap out the depleted battery for a freshly charged one

- Beer taxi

- Bird poo sproingg! automatically quick-dries the offending substance and pops it off of garden furniture for easy sweep-up

- Human sudoku: like life-sized chess, only even more boring

- Self-cleaning BBQ sprays liquid nitrogen onto grill after each use
