thanks for the replies, I've found this here, it says its 62 ah at 10hr rate does this make it 620 ah overall? Could you charge this from the mains after it has used its power or not?

What I want to power is This. So I just need to buy an inverter to convert the current? Is it that simple or ist there more to it? How long would a car battery power the steamer (in the link) for? Would a car battery be most appropriate? I don't know a lot about electricity hence why i'm asking on here! Thanks for the replies so far

Hi I want to start a hot dog business but to save money on gas heaters would it be possible to run a steamer (designed for normal household electrics) off any sort of battery? I'm looking for a way to move to different locations without having to be near a power source the whole time. Is there any sort of portable battery that I could charge overnight and then use to power a small hot dog cart? Thanks Charlie

Hi I've posted this in the physics forum but it might be more appropriate for here; I'm trying to make a layered smoothie that remains layered when shaken. I'm aiming for about 5 alternating layers of 2 different flavours. I was trying to work out the best way to do this, would each layer have to be more dense than the last (smilar to oil floating on water)? Or would I have to reduce the viscosity of each alternating layer by adding something like honey to increase the thickness? The idea is that when the drink is shook it will go back to its normal state of 5 alternating layers and not mix together. Does anyone know how I can do this? Thanks Charlie

thanks, would there be a way to make them so that if you shake it in a bottle the layers would go back to being layers and not mix together? Could you make alternate layers denser to prevent the layers mixing together?

Hi Would it be possible to separate two different flavoured smoothies in one glass so the colours alternate eg apple on the bottom, then blueberry, then apple again, sort of line a rainbow effect in a glass. If so how? Thanks

thanks for the reply, so would the sodium acetate heat pads warm the heat the water, giving the water more energy, resulting in the water staying hotter for longer? The question was looking at keeping a hot water bottle warmer for longer, i'm not looking at increasing the temperature, just maintaining it for longer thanks

Hi I'm just wondering if it would be possible to keep water hotter for longer by using something like a silicone heat pad placed in the water? Would this work? If not what materials should I be looking at to achieve this? Thanks Charlie

thanks, would there be anyway then to reflect the heat away with a aluminium plate under the laptop? So the heat transfers from the laptop to the plate and then is reflected into the air

I'm looking for a material to place my laptop on while its on my lap as it gets hot. What material will best prevent the heat? I had aluminium in mind.... Thanks

Is it possible to have a small pill containing vitamins such as potassium, iron, sodium, calcium, and zinc designed to help sportsmen when performing. The pill would be consumed pre exercise and would give them a boost which will hopefully give them a competitive advantage. Is it possible to combine these vitamins in one pill and have them affect you quickly in the short term? Thanks Charlie

I've recently got into the idea of renewable energy and i'm exploring what opportunities there are. One idea i've come up with is using mirrors to focus the suns heat onto a section of the sea, this heat would be so intense that the seat water would evaporate off to form steam and this can then (smiler to how it happens with nuclear power) turn turbines and then in turn turn a generator to produce electricity. This is just an idea, and i'm not sure if its been done before but is it a feasible concept? Thanks Charlie

yes it would be a more eco friendly way of heating water. I've just recently got into the idea of renewable energy and i'm just trying to explore what opportunities there are.

the reason i'm asking is would it be possible to heat up a house boiler by having a tube inside the boiler with this reaction continuously occurring within it to heat up the water?

Is it possible to combine compounds to be constantly reacting with each other to produce heat? If so what is the most heat a reaction could produce and how long will it last? What compounds would be best to get this effect?

Hi At university my mattress bed keeps slipping off the bed when I sleep on it. I'm trying to find something that would offer friction against the mattress and the metal bed, when placed in between the two. I've tried a rug and that helped but wasn't 100% effective, i'm now using a cotton bath mat and that doesn't work as well as the rug. Will a yoga mat or a PVC mat offer more friction? If not what material will? Many thanks Charlie

thanks for the advice, will the leather glue be strong enough to pull the rubber together and clot which is already taught when inflated ? I'm after as longer term solution as possible. Many Thanks

would it be possible to seal a puncture in a football by injecting glue (or another substance) into the hole in the leather to seal the puncture in the rubber bladder? If not glue what substance would be good? Thanks

Hi I'm looking for a substance that that could clot together to glue two bits of rubber or leather together. Does this sort of substance exist? Any help appreciated! Many thanks Charlie
