As the other kind of heating sources it has its own problems. The wood, as a heating material, has been used for long time so a good erudition and experience were accumulated to solve the problems of wood heating.

Summary
This publication is a book, written by many experts in this field. It consists about 15 parts; each part between 15 and 20 papers. Each part dealing a specific instruction such as:
A concise guide to high performance woodburning

Opinion.
The book adopted in simple language to avoid the complexity. Even the physical and gas dynamics phenomena are explained in smooth way to be understandable to almost every one. It consist a lot of illustrations to help the reader to understand how and why the problems created.
I think it is more than a guide, or a manual. It is written.to help the users of wood heating to know how the process going on; how the problems created; and how to avoid the difficulties.
I think it is important to be read by any person who uses the wood, pellets or woodchips as heating sources.

I have now watched both videos and found both interesting, especially Andrew McAfee's presentation. First I want to point out that I believe the technology will have a major and positive impact in the future when it comes to jobs and development. We should not be afraid of the pace of technological change, but see the possibilities that technology can create instead, if this is done properly.

So, as it stands now and will be with the help of technology, droids are doing and will do many of the jobs that humans used to do, we are in a phase where Droids have taken over many of the jobs for various reasons, including to saving time, more accuracy, less errors in such production and less cost seen in the long term. This can still never be done unless the human direct impact and human control of the labor process.

What may be worrying is if instead of using the time that you save by droids doing the jobs to try to develop ourselves and spend more time doing something useful, many might be unemployed in this case and this will suddenly be a problem. Economically, many people will be poorer and in this case this will leads to different consequences. In other ways, this contributes to the fact that many are getting richer, which in turn creates unbalanced society

Another important aspect we should consider as well when we are discussing this is earth's population and how it is constantly increasing. We need in this case, more jobs; there must be more to do and not the opposite. This becomes complicated if one does not take into account various aspects while development takes place quickly, but we must also at the same time see the possibilities with this anyway and try to take advantage of it.
