How to build a Rocket Mass Heater

How to build a Rocket Mass Heater
There are two main factors that differentiate a Rocket Mass Heater (RMH) from a regular wood-burning stove. One is that the combustion that takes place is far more complete in an RMH, due to the increased draft and insulated burn chamber. An RMH can consequently be up to eight times more efficient, requiring less wood for the same amount of heat. This also results in there being less ash and smoke. The second factor that makes an RMH so superior is the thermal mass that encases the components that heat up. As biomass is burned and the RMH is heated, it transfers heat to the thermal mass (adobe, dirt, sand, even water). This RMH is based around a 6” diameter flue.

DIY: HOW TO DISTILL WATER AT HOME - Prepared For That Distillation is a process of filtering and purifying water, resulting in pure, pH-balanced H-TWO-O. The process consists of: 1) Boiling/evaporating the water, 2) Collecting the water vapor, 3) Cooling it to allow it to condense back into liquid, and then 4) Collecting the liquid. The boiling causes the pure water molecules to evaporate, leaving all impurities behind in the boiling pot. Impurities that distilling will remove include bacteria, viruses, heavy metals, salts, chemicals and particulates.

Raspberry Pi Solar Weather Station Spurred on by the completion of my two previous projects, the Compact Camera and Portable Games Console, I wanted to find a new challenge. The natural progression was an outdoor remote system... I wanted to build a Raspberry Pi weather station that was able to sustain itself off grid and send me the results through a wireless connection, from anywhere! This project really has had its challenges, but luckily powering the Raspberry Pi is one of the main challenges that has been made easy by using the PiJuice as a power supply with it's added solar support. My Initial thought was to use the fantastic AirPi module to take readings. learn.adafruit Time to start exploring more sensors with the Raspberry Pi and Beaglebone Black! Today we'll be checking out the DHT11, DHT22 and AM2302 humidity and temperature sensors available from Adafruit In this tutorial we'll be showing how to install a DHT sensor Python library which utilizes C for high-speed GPIO polling to handle bit-banged sensor output. Many low cost sensors have unusual output formats, and in this case, a "Manchester-esque" output that is not SPI, I2C or 1-Wire compatible must be polled continuously by the Pi to decode. Luckily, the C GPIO libraries are fast enough to decode the output.
