Would a "reverse microwave" be a successful product? ❄

I've never pursued selling a product or making a business before, so I'm here for advice. The next few paragraphs will just explain what it is and the data I've collected. I've invented a new technology that acts like a "reverse microwave". It can have the same size and feel of a microwave, so it can cool both food and beverages at very fast rates. My roughly thrown-together prototype had surprisingly great results: it cools water from room temperature to fridge temperatures 30X faster than a fridge, and it freezes water 3-4X faster than a freezer. Data was collected based on water at room temperature, but it can cool any food and beverage at similar rates. It can be used to cool foods for storage (to avoid dangerous temperature ranges), cool bread for improved preservation, chill beverages, set jello, and chill cookie dough in a matter of minutes. And it cost less than $300 to manufacture. This tech seems to be very significant for restaurants, bakeries, and icecream shops, bakers/cooks in households, and for those who prefer to store canned or bottled beverages at room temperature. My device can as small as a microwave, or larger to accommodate higher cooling volume. In my preliminary survey results, I found that 28.3% of people would be likely to purchase one for their home (especially higher income households), and 34.6% of business owners and employees would be likely to purchase one for business usage. Of those that already own a blast chiller, 55% would purchase. A friend helped me get the us/global market numbers. The US consumer electronics retail market which includes small kitchen appliances is currently $342 Billion and is expected to grow to $375.5 Billion by 2025. The Global Blast chiller market is currently $1billion and is expected to grow at a rate of 7%. I went to some other people about this, and I've been shut down a few times. So I can't tell if that means it's just a bad idea, or if the market just isn't big enough, or if it just wouldn't be very useful... So I'm here to ask a larger group of possibly more experienced people. Is it a good idea to pursue starting a business out of this product?
