It's getting trendy, but how good is it? Caloric values of different fuels:  Engineeringtoolbox   Coal is ~ 2 times more efficient than dry wood, propane is 3~ times per weight For smoke, wood has the most, if used simple open air So for such kind of stove above, it's good for warming, rather than for cooking, or boiling water? Many portable or camp "rocket stove" on market are merely stripped down version of household rocket mass heater:  with a J tube(burning chamber + heat riser),  - air intake duct may be skipped - most without secondary combustion - weak or no venturi effect Recommended portable/camping wood stove: Improved stove from bioenergylists , eg, TLUD gasifier , ~4000BTU/h aprovecho on TLUD , low PM2.5 stove   Peko Pe , aka original TLUD, OSTI research on PM2.5 with Concentrator disc , aka champion TLUD Solo stove and similar ones   MimiMoto  (2016) , forced draft TLUD, aka FD TLUD, wood pellets optimsed,  tier 4  plus emission, 3 sizes of combustion c

一种降低加工和装调难度的离轴TMA光学系统，涉及空间光学技术领域，解决现有离轴TMA光学系统的加工、检测和装调困难进而导致系统难于达到光学成像指标的问题， 本发明将次反射镜设计为球面，主反射镜与第三反射镜设计为非球面，且二次项系数设置为零，所述主反射镜和第三反射镜分别为含六次项和八次项的高次非球面；使离轴TMA光学系统达到了衍射极限光学特性，本发明的传递函数在50lp时接近0.6的成像质量，Strehl Ratio由0.91提高到0.93； 面形加工公差由λ/50放宽到λ/40；主、次、三镜的装调公差放宽4倍。本发明降低了加工及装调难度，有助于系统实现衍射极限的光学特性。 CN102062936B 趙文才 google patents
