Rocket Stove Heating

rocket stove in estonia

A rocket stove is not quite as efficient and clean-burning as a masonry heater, but it is much more DIY-friendly to build. The idea is that the configuration allows excess oxygen to increase the burn temperature of the fire. Hotter temperature means you want to store the heat energy into a high thermal mass material. Lots of great links at I fucking love rocket stoves.

Build a Solar Thermal Direct-Air Heater for $200

“The town I live in is located near the Alberta-BC border, about 100 miles north of the US Canada border. Winters here are long and cold, but many days are crystal clear and sunny.”

“Our tool shed has a south-facing wall which was ideal to mount a solar thermal direct-air collector panel. The collector panel exterior dimensions are 48” high x 49.5” wide. Total budget: $200.00 Result: 16 sq ft harvest up to 6 kWh/day.”

Micro Heaters

Microheaters“In June of 2010 I moved to a place in Montana with only electric heat. By myself. In the past few winters I had conducted experiments in cutting the amount of energy I needed to stay warm, with a focus on heating myself instead of heating the whole house.”

“I had a lot of motivators here, but the primary motivator was the greenwashing being done around fluorescent light bulbs. My power company sent me literature telling me that I should replace all of my incandescent light bulbs with fluorescent light bulbs to save energy and money. Based on my lighting usage, the most I could possibly save is $5 per year. Yet, with changing my heating habits, I think I have proven that I can save $500 per year.”

Solar Heating System with Water Battery

Solar Heating System with Water Battery

Dutch inventor Kees van der Geer sends us this paper and wants to know what we think of it. Comments are open.

“Heating with a sun collector costs nothing and contaminates nothing. In this article I propose a solar heating system consisting of a large solar collector, suitable for the heating of a house and a heat store, capable to bridge a week of cloudy weather. Both are made from simple materials.”

“Maybe a practical solution to make a heat store is to buy a inflatable swimming pool of 17m3 and construct an insulating box around it. ”
