2.       As it relates to your investment in Edyza, please clarify and
reconcile the following
         disclosure:

              You previously disclosed in your Form S-1 that in August 2017
Edyza issued the
              Company a convertible note in the principal amount of $400,000,
which is
              convertible into a 5% interest in Edyza, at your election. Please
revise to clarify if
              the Simple Agreement for Future Equity was an agreement in
addition to the
              convertible note or if the Simple Agreement is the convertible
note you previously
              disclosed. In this regard, we note the 442,685 shares issued to
you at a conversion
              price of $0.09 equates to $40,000 and not the principal amount of
the convertible note
              of $400,000 you received in exchange for your cash investment of
$400,000
              disclosed on the statement of cash flows for the year ended
December 31, 2017.

              We note your disclosure that your purchased an additional 442,685
shares for
              $400,000 or approximately $0.90 per share of which only $325,000
had been paid as
              of December 31, 2018. Please tell us and disclose the nature and
amounts other than
              the $325,000 paid to Edyza during the year ended December 31,
2018 comprising the
              remaining cash investment of $87,833.

              You indicate cash investments of $205,250 were made for the nine
months ended
              September 30, 2019. Please disclose the nature and amounts of
these investments
              including whether you acquired additional ownership over the 10%
as of December
              31, 2018.
3.       As it relates to your investment in TGH, please clarify and reconcile
the following
         disclosure:

              Your note disclosure indicates you purchased an initial 5%
interest in TGH in
              February 2018 for $125,000 and another 5% under the first option
for $150,000 in
              July 2018. Please explain the nature and amounts of the
additional cash investments
              of $173,766 in deriving your cash outflows of $448,766. In this
regard, your
              disclosure indicates the second option of an additional 15%
interest for $525,000 was
              not exercisable until 2019.

              We note in January 2019 the Company and TGH negotiated the terms
of the second
              option of 15% for $525,000; however, your disclosure indicates
you had already paid
              $158,000 as of December 31, 2018 with future payments of $36,000
due every two
              weeks through May 2019 until the remaining balance of $367,000
has been paid.
              Please clarify why payments appear to have been made on the
second option before it
              was exercisable and before you entered into negotiations with
regard to the second
              option.

              We note beginning in May 2019 you have disclosed you account for
your investment
              under the equity method. Please tell us the amount of the
Company's share of
