Menarik sekali pakde...

Dan ternyata sebenernya emang aplikasi Hydrogen udah banyak...
tanya-tanya ke embah wiki... dapet artikel ini...

Limelights used an oxyhydrogen flame as a high-temperature heat source

[edit] Lighting

Many forms of oxyhydrogen lamps have been described, such as the limelight, which used an oxyhydrogen flame to heat a piece of lime to white hot incandescence.[6] Because of the explosiveness of the oxyhydrogen, limelights have been replaced by electric lighting.

It was much used in platinum works,[citation needed] as platinum could be melted (at a temperature of 1768.3 °C) only in an oxyhydrogen flame, or an electric arc furnace (which is now used instead).

[edit] Oxyhydrogen torch

An oxyhydrogen torch is an oxy-gas torch, which burns hydrogen (the fuel) with oxygen (the oxidizer). It is used for cutting and welding metals, glass, and thermoplastics.[6] An oxyhydrogen torch is used in the glass industry for "fire polishing"; slightly melting the surface of glass to remove scratches and dullness.[citation needed]

The oxyhydrogen flame begins a short distance from the torch tip; if the distance is great enough the torch tip can remain relatively cool.[7]
Menarik juga... kalo ternyata oxyhydrogen sendiri bisa dipake buat ngelas... apalagi yang satu ini kan bukan dari air... tentu potensialnya lebih tinggi lagi...

Cuma keknya kalo internal combustion engine pake gas H2 murni tanpa lain-lain agak susah... karena menurut hukum Termo 2 efisiensi cuma 20%... jadi ya penghemat bahan bakar... iya... tapi pengganti belon...

Salut juga sih... yang penting kan hemat dulu... hehehe...


Oh ya pakde... masalah flashback...
itu di alat las karbit kan ada flashback arrestor...
Sistemnya dia pake air gitu... jadi gasnya diewatkan bawah air sehingga gelembung-gelembungnya keluar lewat air... jadi kalo flashback dia aman...

bisa diterapkan ga kira-kira?
