Dear Dhan

>The Biolite isn't very good.

I am not sure how you qualify that.  It was not the first stove to have a TEG but it has been internationally successful.  The mechanism it uses to limit the heat transferred to a level that does not damage the TEG.

>If i remember correctly,Aprovecho has an 18 watt Thermo-Electric Generator.

There are TEGs available for installation into stoves as a kit from a company called TEG-tech which can generate up to 300 Watts from a space heating stove.  The winner of the Clean Stove competition held on the Mall in DC a few years ago generated 50 Watts continuously.  It was using power to run two cooling fans and still generated 50 Watts.

>Surely $100 is a lot of money in Uganda,

Yes it is – many people were surprised to hear this.

>it would be better to make a stove with a TEG themselves or pay a handyman to make one. It could be a good business.

That sounds really easy.  Try it.  You will discover why these things were not mounted in all stoves already.  Fortunately recent developments are making them more reliable and they have increasingly large temperature ranges.

>It could be disastrous if mankind has "unlimited" energy, even "clean" energy,
at it's disposal.

Why? I think it is a great idea.  Many things related to sustainability are a problem because of a lack of affordable energy.  When we have boundless energy we can sole a huge number of problems.  My bet is on 5th generation nuclear power.

Dear Dan

I hear people are buying a Biolite stove in Uganda for $100 and running it all day to play the radio.
Net biomass consumption is up in those households.
Good or bad?  It is renewable....

Doubts on progress and technology
The articles are very well written.They even have a SOLAR-POWERED WEBSITE, based in Spain.

Coppicing.... Pollards & Hedgerows....Line Plantings
Harvesting wood from living trees instead of killing them is beneficial for the life forms that depend on them. Coppice forests can have a richer biodiversity than unmanaged forests, because they always contain areas with different stages of light and growth. None of this is true in industrial wood plantations, which support little or no plant and animal life, and which have longer rotation cycles (of at least twenty years).

How to Make Biomass Energy Sustainable Again

From the Neolithic to the beginning of the twentieth century, coppiced woodlands, pollarded trees, and hedgerows provided people with a sustainable supply of energy, materials, and food.

How is Cutting Down Trees Sustainable?

Advocating for the use of biomass as a renewable source of energy – replacing fossil fuels – has become controversial among environmentalists. The comments on the previous article, which discussed thermoelectric stoves<https://eur05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsolar.lowtechmagazine.com%2F2020%2F05%2Fthermoelectric-stoves-ditch-the-solar-panels.html&data=04%7C01%7C%7C461472d13a774b80b3b908d888f44e40%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637409930148080072%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=r8FmvUf17wBzju4lG9ITm5o9TAKDc9ETh7PBubntRFA%3D&reserved=0>, illustrate this:

  *   “As the recent film Planet of the Humans points out, biomass a.k.a. dead trees is not a renewable resource by any means, even though the EU classifies it as such.”
  *   “How is cutting down trees sustainable?”
  *   “Article fails to mention that a wood stove produces more CO2 than a coal power plant for every ton of wood/coal that is burned.”
  *   “This is pure insanity. Burning trees to reduce our carbon footprint is oxymoronic.”
  *   “The carbon footprint alone is just horrifying.”
  *   “The biggest problem with burning anything is once it’s burned, it’s gone forever.”
  *   “The only silly question I can add to to the silliness of this piece, is where is all the wood coming from?”

In contrast to what the comments suggest, the article does not advocate the expansion of biomass as an energy source. Instead, it argues that already burning biomass fires – used by roughly 40% of today’s global population – could also produce electricity as a by-product, if they are outfitted with thermoelectric modules. Nevertheless, several commenters maintained their criticism after they read the article more carefully. One of them wrote: “We should aim to eliminate the burning of biomass globally, not make it more attractive.”
Apparently, high-tech thinking has permeated the minds of (urban) environmentalists to such an extent that they view biomass as an inherently troublesome energy source – similar to fossil fuels. To be clear, critics are right to call out unsustainable practices in biomass production. However, these are the consequences of a relatively recent, “industrial” approach to forestry. When we look at historical forest management practices, it becomes clear that biomass is potentially one of the most sustainable energy sources on this planet.
