[Stoves] Karve kilns was Re: Looking for a stove designed for larger amounts of biochar

[Anand Karve]

Dear Paul,
The CD of our energy technologies shows the construction and operation
of our compact biogas model, the oven-and retort process of charring
as well as the single barrel TLUD kiln. It also shows how the
briquettes are extruded and how they are used in our Sarai cooker. We
had arranged with Pay Pal that a payment of US$ 10 would allow people
to download this video film, but due to some regulations of the
Government of India, Pay Pal stopped giving us this service. An
interested person can always buy the CD from us, by paying us US$40,
but unfortunately the monetary transaction (payment through a bank) is
an additional cost which the client has to bear.  We send the CD to
any address in India if we receive a payment of Rs.300 (US$6). This
includes the courier charges within India. People have often paid us
in Indian Rupees with a request to send the CD to an address outside
India. In that case the courier charges to the foreign destination are
charged extra. Bank-to-bank transactions in Indian Rupees cost nothing
within India. I shall ask the administrators of our Web Site, if they
can allow downloading by an individual customer, who pays the
requisite amount to us directly. That would at least save the customer
the postage and packing charges.
Yours
A.D.Karve
