solid-state microwave cookers were still in the developmental stage and had not yet become widely commercialized. However, I can provide some potential reasons why the commercialization of solid-state microwave cookers might have been taking longer:
Technological challenges: Developing solid-state microwave cookers with the desired efficiency, power output, and safety features can be technically challenging. Solid-state devices must be able to generate and control microwaves effectively without the use of traditional magnetrons, which are the vacuum tube devices used in conventional microwave ovens.
Cost of development: The research and development process for new technologies like solid-state microwave cookers can be expensive. Companies need to invest significant resources in designing, prototyping, testing, and refining these devices before bringing them to the market.
Safety and regulations: Microwave ovens are widely used in households and commercial settings, so ensuring the safety and compliance with regulations is of utmost importance. Solid-state microwave cookers need to meet stringent safety standards before they can be commercialized.
Market demand and competition: Companies might be hesitant to invest in solid-state microwave cookers if the demand for such products is uncertain. Additionally, they need to consider competition from existing microwave oven manufacturers, who have well-established products and market share.
Consumer acceptance: Introducing a new technology into the market requires gaining consumer trust and acceptance. Consumers may be cautious about adopting a new type of microwave oven without a proven track record of performance and reliability.
Research and testing: To ensure the reliability and efficiency of solid-state microwave cookers, extensive research and testing are necessary. This can extend the time it takes for these products to become commercially viable.
