It never ceases to amaze me how
unwilling the people we see on PF who say they believe they have discovered something are to put any real money or effort into their idea (even after years or decades!). This tells me they don't really believe in it (or maybe their belief is not stronger than their fear). If you watch a TV show like "Shark Tank", you'll see the majority of the people who are on the show go all in on their idea, investing enormous amounts of time and money into it before it gets to the point where it is ready to be presented to billionaire investors. A patent application alone probably costs upwards of $10,000. Then there's prototyping and if it goes well, setting up manufacturing and distribution. People with even small, simple ideas often spend a $100,000 or more developing an idea to get it far enough that it is ready to sell - and therefore invest in.
For someone who has a scientific idea, here's all it takes to get a quick review: $600 and an afternoon. Find a random physicist at a nearby university and offer him/er $150 an hour to spend the afternoon with you at a coffee shop to read your paper, review and discuss.
Don't trust the answer you got? Go get another opinion.
I'm a mechanical engineer, not a physicist, but if someone local made me that offer to review their perpetual motion machine idea, I'd do it. I bet you can find a physicist who would too.
@bugs007, you say you've put 30 years into this idea. I urge you to take just a little bit of time and money and find out if your idea does or doesn't have merit. The worst case outcome from that is just that if you find the idea doesn't have merit you save yourself any further waste of time. So even that would be a win.
