How to make electric water heater with razor blades (DIY)

Items Required: 2 razor blades, 30 Amp electrical wire, 2 toothpicks & electric plug.



How it works: It is boiling the water through molecular friction as well though. You get some electrolysis because that's what passing electrical current through water does... it splits the molecules of water into their constituent elements (2H2 O2 if you want it balanced) simply because you're giving the molecules the energy they need to be able to split. If you used AC power as an electrolysis cell though it'd be roughly 10% efficient, with the remaining energy wasted as resistance in the wire, the plates and heating the water, whereas it's much higher for a DC powered electrolysis cell. Anyway, by using an AC power source instead of DC, you agitate impurities in the water, such as salts and metallic ions (As these conduct the electricity and not the water itself. The water merely acts as a solvent to suspend the molecules and itself isn't very conductive), which produces molecular friction, and this friction produces the heat that causes the water to boil. The more impure/harder the water, the faster it'll boil but also the more power you'll draw with it. If you decide to make an electrode boiler yourself, you really need to have heavy gauge mains cable capable of at least 10 amps of current for a reasonable boiler in a hard water area. (Depending on your line voltage and the impurities in the water, you should see:



JP/CN: Up to 1.1kW of power @10A 110v

USA: Up to 1.2kW of power @10A 120v

UK/AU: Up to 2.4kW of power @10A 240v

EU: Up to 2.2kW of power @ 10A 220v



If you have hard water in your area (loaded with salts and impurities that conduct electricity well) then you will likely see more than the 10A of current draw that I quoted here hooking one of these electrode boilers directly to the mains. Again, you HAVE to take care with a project like this... Especially if you live in a country that uses a 220 or 230v 13A supply for its sockets!!?
