    Hi all

    I am new to this website but found it recently when searching for a way to develop an idea I have come up with. I also have no experience with electronics/circuits/heating or plumbing so really need a lot of help if I am to get my idea off the ground

    My idea involves keeping a food item warm for approximately 10-15 minutes. It does not have to be at a high temperature but the food needs to remain hot enough for butter to melt on it and still be edible.

    the method of warming will use a series of tubes that would have a heating element running through them. this element may have insulation around it to maintain the temperature but the element would need to be battery powered. the battery could be rechargeable and be plugged in periodically to recharge or could run off disposable batteries.

    My questions are :
    Could a heating element be run off batteries in this way and if so how?
    What materials would be best to maintain a steady temperature?
    Would I need to use some form of insulation to maintain the temperature?
    Also, if any inventors on here have any adice about the best way to go about patenting an idea that does not yet have a working prototype that would be great.

    If anyone would like further information about my project they can contact me on <SNIP> It is an idea that, I feel, could possibly make a big profit if sold to major hotel chains and solves an issue that people have been facing when visiting hotels for years. However, as I have not patented the idea I do not wish to put all my cards onto the table on a public forum such as this. But, if I could set up an email conversation between myself and another user or users of this forum I would be happy to let them come in on the project and potentially share the profits. It is a bit of a pipe dream (pardon the pun) but it has been swimming around my head for a long time and I would now like to create a prototype so that I could go about patenting the idea. Anyone who has experience in this field and fancies a bit of an adventure can get in touch. I have a background in art and design so really only need help with the technical aspects and then maybe learning ow to take a product to market. Hope to hear from someone soon. FYI I am based in the West Midlands UK and would be able to meet any potential partners if they live local or we can correspond by post/email if you live in another part of the world.

    Thanks in advance

    Welcome to the forum.
    Be aware that public disclosure of your invention before applying for a patent will prevent you getting a valid patent. As you have now disclosed publicly the concept of using a tubular food-warmer having a heating element, that concept (even if it were novel and non-obvious) is not now patentable in the UK or Europe (although undisclosed details of its implementation might be).
    Whether or not you have a working prototype is irrelevant for UK or European patents.

    This project will come down to how much power you require.
    The rest should be easy.

    Find a heater that does what you want, and measure the power requirement!

    It may require an automotive sized battery. We really don't know without knowing power requirements.
