The Idea

This is a great idea, It is a 10"x 10"x 12" lunchbox with a cooler & microwave combined. One end will be used as a cooler with a re-freezable core and the other end will be a mini microwave power by a rechargeable battery housed on the bottom of the box, and on the side will be storage bags for knives, forks, mustard, ketchup, salt, pepper, etc. Everyone can benefit from this invention, Kids @ school, Workers @ work, Hunters in the woods, Fishermen fishing, Travelers on the road, Mothers @ games, etc. It will also make America healthier by keeping them eating hot healthy they made earlier, instead of the unhealthy Fast Foods that are making the U.S. Citizens the Fattest in the World. Box will come in choice of colors from camouflage, flamed, gloss, flats, teams, etc., depending on the buyer.

I thought of this idea when I was...

Thought of this when I was setting in a woods hunting in the cold and had to eat a froozen sandwich and chicken for lunch.

Rich: it exists..

itsafast1 Posted: December 19, 2007, 6:04 am

The WaveBox needs a power sorce, can use house, generator, or has two clamps for your car battery, I don't plan on driving in the woods or lugging a car battery with me. Read the instruction on it and watch it on YouTube... No-one has a Battery powered box yet.

Rich2809 Posted: December 19, 2007, 8:52 am

You would need a car battery

itsafast1 Posted: December 19, 2007, 9:52 am

The unit I have will have a flat base mount battery on the underside, recharge every night and take your leftovers to work. QVC and Home Shopping Network people would go crazy over this, kids can take stuff out of the fridge and construction workers can stay on the job and save money. This could put money in our pockets as well as the consumer, everyone benifits. Like I say, this would be a self contain unit needing no power-sorce from anywhere, just itsself, Take it on a plane too, who wants a $3 bag of chips and a $6 cold sandwich in the Coach Area that is.

Rich2809 Posted: December 19, 2007, 10:26 am

Okay. You need to speak to a patent lawyer. You need to design it. You need to find a battery that would be light enough to lift and powerful enough to run a microwave. That is not easy.

I just can not see this on an airplane anytime soon.

itsafast1 Posted: December 19, 2007, 10:39 am

You know the plane would smell better, Fried Chicken, Steak, Rice, Egg Rolls, Seafood. International Smelling Comp. on a plane .. Ha Ha Ha

darlinglilred Posted: December 19, 2007, 11:34 am

I'm fairly sure with the seriousness that they take airport security these days that you would not be able to take one of these on a plane.

ccozad Posted: December 19, 2007, 5:07 pm

itsafast1 spent too much time staring at the microwave as a kid....

itsafast1, my suggestion is for you to build a prototype and get back to us. Beyond that you are wasting people's time. (Unless I have it all wrong and someone has been waiting for the right microwave project to work on)

Kevin_Cox Posted: December 20, 2007, 1:26 am

This idea would cost a lot to make happen. Not very CH as it is hardware. Next, there is was all ready made by another company as Rich2809 pointed out.

davidwei Posted: December 21, 2007, 7:16 am

For the one that exists, I bet there are both safety and weight issues - a battery might make it worse.

itsafast1 Posted: December 21, 2007, 9:24 am

Battery weighs 5.6 lbs, everything to make it work weighs in at 11.8lbs, yes we have a unit finished after finding a few people that knows about the working parts of a microwave.The battery is a dry cell carbon cased part that is very cool and hold alot of power for this small unit, its not made to run 15 minute for a turkey meal, just up to a minute for warm-ups. The weight issue, well leave the lead strap on weights home and carry this.

doaks Posted: December 24, 2007, 10:49 pm

breakable. . . .an i dont want a 11.8pound lunchbox lol

Hughgoh Posted: December 26, 2007, 1:41 pm

Maybe you could use some type of solar heater, it would be lighter. Have some panels that unfold to reflect the energy to the meal to be heated. Good Luck

Kevin_Cox Posted: December 26, 2007, 4:24 pm

Why would people that need a microwave go camping in the first place?

tlyden Posted: December 28, 2007, 12:21 pm

good point, kev- microwave does not equate camping

TheGuru Posted: May 30, 2008, 1:01 pm

This is a trivial idea. It would not cost much at all to make a prototype.
1. go to walmart and buy the smallest microwave you can 500W (50$)
2. buy an 800W power inverter. this converts ~12V to 110VAC (30$)
3. buy some laptop or camcorder lithium batteries and chargers
(or use a bunch of C/D rechargeable cells in a carrier to get 12-16VDC)
4. microwave away!
Problems - the batteries will not last long. Say at 500W, the magnetron will consume ~800W (~60% efficiency only). The power inverter will consume over 60 A at 12V (assuming 100% efficiency on the inverter). You might get a minute or two tops out of a set of batteries unless you plan to carry a truck or car battery with you. Of course you can get a 12V powered microwave oven to avoid the inverter. To improve the situation, get yourself a really tiny cavity magnetron, a custom enclosure, electronics and lightweight lithium battery. It won't weigh much less than 15 pounds with the shielding required. You will also need proper engineering, testing, and regulator approvals. $$$$$
