Is there anyone out there that wants to build these under licence? There's no competition and the market is worldwide. I've got detail engineering drawings, a tech spec, and a working prototype. What more do you need?
Is this your invention?
Hello Bob.First, if it was me, get a patent to protect the idea!Here's a couple of useful links with lots of advice which may help.
Click the link>>> Patenting your invention - Advice on the official UK .gov website.
Click the link>>> Business Is Great - Funding and Support for new ideas - Advice, funding and more.
Click the link >>> Innovate UK - They can help with everything but never personally used them and there are probably other companies out there that are similar.Good luck with this because you never know how well this could go.
