I'm very skeptical that these technologies will be more efficient than incumbent solutions. These products seem to be designed to comport with well intended political goals, rather than consumer preferences.

It may be that these products are taxes-by-another-name, as consumers either shell out more money for inferior solutions (ebikes, I guess), or, turn to the secondary market instead (for gas leafblowers, say).

After seeing what we did with recycling, I would not be so naive going forward, on the claims of environmentalists. (I still have yet to see the research on the electric car co2 implications of producing batteries and offloading co2 output to power plants, when compared to the incumbent solution)
