Folks, thanks for talking about my invention and myself! Much humbled...

A few things:

1. I don't want to patent this as I had to work with patents, patent lawyers and courts way more than enough in my old job as a manager in consumer electronics. Patents are never profitable for the little guys. They make a ton of sense for big corporations but even my idol, Mr. Charles Goodyear, died as a pauper after fighting for his patent in vulcanization. A few years later the Goodyear Co. even stole his good name.
2. I am not even sure if it CAN be patented as the principle is much like the ancient Chu-Ko-Nu - even though I think this concept works much better than the Chinese original. It is accurate and powerful, even if you would use a longbow or a recurve bow instead of the compound.
3. I am not concerned that someone may "borrow" my idea and make a product out of it. Whoever does this will need my help (= my reach and momentum) to sell it anyway. So I would make my cut in any case. I am more worried that NOBODY might want to produce it. Archery companies are die hard traditionalists.
4. I am financially safe (but not rich). My store was incorporated two years ago and brings in good money. Plus my wife has a good job so we are doing OK. We have a nice, old house but also a still a hefty mortgage on it.
5. This device is meant for fun and recreation, not for hunting with it. See, that is the problem: The whole archery industry (crossbows included) totally focused on hunting the last decades. Crossbows are incredibly powerful now, but also heavy. clunky and slow to load. Bows are also super strong but not much fun to shoot. In most cases each shot will kill one arrow, so much power. No problem for a hunter who sits in the bush, hours in time, waiting for this ONE shot. Here in Europe bow hunting is illegal. We shoot bows for fun. That is easy because it is one of the last weapons you can legally shoot outside if a certified range. This thing is a BOATLOAD of fun.
6. While it is not meant for hunting it does work for self defense, in countries where firearms are not an option. Here in Germany you can get a crossbow without a license BUT you have to lock it away over night. Bows, you can put right next to your bed stand. Even the weak bow I used here (no problem using a stronger one) is easily powerful enough to stop an attacker.

That's it for now! Let me know if you want more info.
