Anyone know of a cordless battery kettle?

[James07]

A kettle uses so much power I wouldn't think so!

So how are you going to use it when out camping or somewhere that you'd need a battery one in the first place then?

The same rugrats where they found a load of rubbish in the garage and turned it into a spaceship?

Well. Where are these battery powered kettles then!?

About the best you could get is this. You just couldn't do the same thing with batteries and this will work again and again.

Surprised you haven't gone for a pedal, solar or wind powered kettle to take advantage of the free energy!

I'm actually tempted to make a boat with a big black roof, pipe water through it, and feed it to one side of a Stirling engine, the other side is a metal plate forming part of the hull.

Should be quite capable of movement.

Q = MC delta T

0.5l x 4,200J x 80C = 168,000 Joules to boil 500ml of water.

Best Ni-Mh batteries = 11,664 Joules.

168,000/11,664 = 14 AA batteries for one boil, the battery pack would weigh 331g and would take 20mins to discharge that much energy without overheating.

A useful portable kettle would therefore have to have about 140 AA batteries which would weigh 3.3KG and would last 10 boils taking 2 mins each. Not really practical is it?

Then 14 hours before you can have another cup.

I would like to see someone make one though, I can just imagine taking 3KG of batteries camping with you and connecting them to the kettle.

Things to do when your a millionaire I think. Hook it upto a car battery or even better the actual car might be the best idea since their biggest output is heat


A chemical reaction directly heating something would be feasible, I think its been done or is even used by the army maybe

Battery powered generator, innit.

He was searching for a niche in the market.

Quick, someone patent a battery powered kettle.

 

[doozer]

Get a usb powered one if your too lazy to get up from your pc chair.

When you go camping, I hope you get rogered by a Grizzly.
