During the three quarters of fiscal 1999, options to purchase 764,537 shares
of common stock at prices ranging between $1.63 and $22.50 per share were
outstanding but were not included in the computation of Earnings per Share-
assuming dilution because the Company incurred a loss during this period and
inclusion would be anti-dilutive.  The options, which expire between December
20, 2006 and June 16, 2009 were outstanding at June 25, 1999.

During the three quarters of fiscal 1998, options to purchase 30,000 shares of
common stock at prices ranging from $5.70 to $6.00 per share were outstanding
but were not included in the computation of Earnings per Share-assuming
dilution because the option exercise prices were greater than the average
market price of the common shares (anti-dilutive). The options, which expire
on October 20, 2007 and April 27, 2008, were outstanding at June 26, 1998.

4.	Investment in Plug Power, L.L.C.

On April 15, 1998, Edison Development Corporation ("EDC") contributed $2.25
million in cash to Plug Power, L.L.C. ("Plug Power").  The Company contributed
a below-market lease for office and manufacturing facilities in Latham, New
York,valued at $2 million and purchased a one year option to match the remaining
$250 thousand of EDC's contribution.  In May 1998, EDC contributed an additional
$2 million to Plug Power and the Company purchased another one year option to
match the contribution.  The Company paid approximately $191 thousand for the
options, which matured April 24, 1999 ($250 thousand) and June 15, 1999
($2 million).

As of March 25, 1999, the Company and Plug Power exchanged the foregoing
options and certain "research credits" (described below) for 2.25 million
Plug Power membership interests. The Company earned the research credits by
assisting Plug Power in securing the award of certain government grants and
research contracts during the period June 1997 through April 1999.

In August 1998, the Company committed to contribute an additional $5 million
dollars (in cash, accounts receivable and research credits) between August 5,
1998 and March 31, 1999 and recorded a liability representing this obligation.
During the period September 1998 to February 1999, the Company fully funded
this commitment by contributing $4 million cash and converting $.5 million of
accounts receivable and $.5 million of notes receivable.

During April 1999, the Company and EDC amended and restated a prior agreement
granting MTI and EDC the right to purchase membership interests in Plug Power.
The agreement, which was effective as of January 26, 1999, states that, in the
event Plug Power determines that it requires funds at any time through
December 31, 2000, Plug Power has the right to call upon the Company and EDC
to each make capital contributions as follows:

        *  The Company and EDC will each fund capital calls of up to
           $7.5 million in 1999 and $15 million in 2000 ("Capital Commitment").

        *  In exchange for such capital contributions to Plug Power, the
           Company and EDC will receive class A membership interests ("Shares")
           from Plug Power at $7.50 per share.

        *  The Company and EDC will share the Capital Commitment equally.

        *  Plug Power's Board of Managers will determine when there is need
           for such capital contributions.

        *  The Company and EDC shall have sixty (60) days from the date of
           such authorization to tender their payment to Plug Power.

The agreement will terminate on December 31, 2000 or the date of an initial
public offering of shares by Plug Power at a per share price of greater than
$7.50 per share ("Termination Date").  In exchange for the Capital Commitment,
Plug Power has agreed to permit the Company and EDC to make capital
contributions to the extent of their Capital Commitment on the Termination
Date, whether or not such funds have been called, in exchange for Shares at
the fixed price of $7.50 per share.



                MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

If Plug Power requests capital contributions pursuant to the Capital
Commitments  ("Capital Call"), and either the Company or EDC fail to make such
capital contribution ("Defaulting Member"), then such Defaulting Member shall
forfeit the right to receive the Shares it would have received in the Capital
Call at the fixed price of $7.50 per share ("Defaulted Shares").  Additionally,
to the extent that there are Capital Commitments outstanding, the Defaulting
Member will be required to forfeit the right to receive an additional number of
Shares, at a fixed price of $7.50 per share, equal to two times the Defaulted
Shares ("Additional Defaulted Shares").  The non-Defaulting Member may fund the
Defaulting Member's share of the Capital Call in exchange for Shares at the
fixed price of $7.50 per share.

In June 1999, MTI and Plug Power entered into an agreement for the sale of the
MTI campus and adjacent residence, including all land and buildings, to Plug
Power in exchange for 704,315 Class A membership interests and the assumption
of approximately $6 million in debt by Plug Power.  The sale of the MTI
facility and the transfer of the $6 million IDR bonds to Plug Power were
effective as of July 1, 1999 with no gain or loss recognized.

The Company's total contributions to Plug Power (including contributions of
cash, assets, research credits, and a below market lease) for the period
commencing onJune 27, 1997, and ending on June 25, 1999 total $14 million.
The Company's total contributions to Plug Power as of July 1, 1999 total
$14.3 million.

During calendar 1999, Plug Power's equity increased approximately $32.483
million primarily due to investments by investors.  Of this amount, $23.368
million was received in cash, $4.990 million in property and services and
$4.125 million represents membership interests issued in connection with the
formation of GE Fuel Cell Systems LLC. As a result, the Company recorded its
proportionate share of the increase in Plug Power's equity ($11.576 million)
as investment in the joint venture and additional paid-in-capital.

The Company has recorded its proportionate share of Plug Power's losses to the
extent of its recorded investment in Plug Power. The carrying value of the
Company's investment is $5.938 million as of June 25, 1999.

The Company will recognize its proportionate share of losses in the future to
the extent of its carrying value and additional future investments.

Plug Power will continue to need substantial investment after December 31,
1999.  Plug Power continues to pursue additional sources of capital.  There is
no assurance, however, that Plug Power will find other sources of capital.  If
other sources of funding cannot be found, the Company will be faced with
contributing and/or lending additional capital to Plug Power or dilution of
its interest in Plug Power. If EDC, the Company and other Plug Power members
stop funding Plug Power and no additional sources of capital are found, Plug
Power will not be able to continue as a going concern.

5.	Reclassification

Certain fiscal 1998 amounts have been reclassified to conform with the fiscal
1999 presentation.

7.	Discontinued Operations

The sale of the Company's Technology Division, the sole component of the
Technology segment, to NYFM, Incorporated (a wholly owned subsidiary of Foster-
Miller, Inc., a Waltham, Massachusetts-based technology company) on March 31,
1998 completed management's planned sale of non-core businesses.  Accordingly,
the Company no longer includes Technology among its reportable business
segments and now operates in only one segment, Test and Measurement.  The
Technology Division is reported as a discontinued operation as of December
26, 1997, and the consolidated financial statements have been restated to
report separately the net assets and operating results of the business. In
exchange for the Technology Division's assets, NYFM, Incorporated (a) agreed
to pay the Company a percentage of annual gross sales in excess of $2.5
million for a period of five years; (b) assumed approximately $40 thousand
of liabilities; and (c) established a credit for warranty work of approximately
$35 thousand.

The Company's results for the third quarter of fiscal 1999 include a $41
thousand gain on the sale of the Technology Division calculated as a percentage
of NYFM's first year gross sales in excess of $2.5 million as of March 31, 1999.

8.	Debt

The Industrial Development Agency for the Town of Colonie issued $6 million in
Industrial Development Revenue ("IDR") Bonds on behalf of the Company to assist
in the construction of a new building for Advanced Products and the Company's
corporate staff and renovation of existing buildings leased to Plug Power. The
bond closing was completed December 17, 1998 and proceeds of the IDR Bonds were
deposited with a trustee for the bondholders.  The Company has drawn the bond
proceeds to cover qualified project costs. First Albany Companies, Inc. ("FAC"),
which owns 34% of the Company's stock, underwrote the sale of the IDR Bonds. FAC
received no fees for underwriting the IDR Bonds but will be reimbursed for its
out-of-pocket costs.

KeyBank issued a letter of credit for approximately $6 million in connection
with the $6 million IDR Bonds.  The KeyBank credit agreements require the
Company to meet certain covenants, including a fixed charge coverage and

               MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

leverage ratio.  Further, if certain performance standards are achieved, the
interest rates on the debt may be reduced.

The debt and the letter of credit obligations were transferred to Plug Power,
LLC in connection with the sale of the MTI facility effective July 1, 1999.

As of June 25, 1999, KeyBank waived certain covenant violations and as of
March 26, 1999, the KeyBank credit agreement was amended to modify certain
covenants to conform with the Company's current performance projections.

11. Equity

On April 23, 1999, the Company declared a 3 for 2 stock split in the form of a
stock dividend.  Holders of the Company's $1.00 par value common stock received
one additional share of $1.00 par value common stock for every two shares of
common stock owned as of April 30, 1999.  The financial statements for all
prior periods have been retroactively adjusted to reflect this stock split
for both common stock issued and options outstanding.

12. Subsequent Event

Effective July 1, 1999, the Company closed the sale of the MTI facility,
including a residence located adjacent to the campus, to Plug Power, LLC in
exchange for 704,315 Plug Power Class A membership interests and the
assumption of $6 million in debt by Plug Power.

On July 9, 1999, the Company completed the sale of 801,223 shares of common
stock to current shareholders through a rights offering.  The offering raised
approximately $12.82 million before offering costs of approximately $.17 million
for net proceeds of approximately $12.65 million.  The Company will use some or
all of the proceeds of the offering for further investment into Plug Power.  In
addition, some proceeds may be used for acquisitions for the Company's core
businesses, efforts to increase market share, working capital, general corporate
purposes and other capital expenditures.

In connection with these transactions, the Company's balance sheet will be
impacted as follows:

                 MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                        MANAGEMENT'S DISCUSSION AND ANALYSIS
                  OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is management's discussion and analysis of certain significant
factors which have affected the Company's earnings during the periods included
in the accompanying consolidated statements of income.

    The sale of the Company's Technology Division, the sole component of the
Technology segment, to NYFM, Incorporated (a wholly owned subsidiary of Foster-
Miller Inc., a Waltham, Massachusetts-based technology company) on March 31,
1998 completed management's planned sale of non-core businesses.  Accordingly,
the Company no longer includes Technology among its reportable business segments
and now operates in only one segment, Test & Measurement.  The Technology
Division is reported as a discontinued operation as of December 26, 1997 and the
consolidated financial statements have been restated to report separately the
net assets (liabilities) and operating results of the business.

Continuing Operations

    Sales decreased $3.16 million to $2.61 million for the three months ended
June 25, 1999 as compared to $5.77 million for the three months ended June 26,
1998, a 54.8% decrease.  This decrease is the result of continuing weak market
conditions.  Sales for the first three quarters of fiscal year 1999 versus the
same period in fiscal year 1998 have decreased $7.4 million to $8.61 million in
1999 from $16.02 million in 1998, a 46.2% decrease. The nine-month changes are
the result of the same conditions as the three-month changes.

	Selling, general and administrative expenses decreased $.56 million to
$1.14 million for the three months ended June 25, 1999 as compared to $1.7
million for the three months ended June 26, 1998, a 33% decrease.  This decrease
is the result of additional cost reduction efforts in fiscal year 1999 and
decreased commissions as a result of decreased sales.  Selling, general and
administrative expenses during the three-quarters of fiscal 1999 of $3.52
million represented a $1.09 million decrease or a 23.7% decrease from $4.61
million incurred during the same period in fiscal 1998.  The nine-month changes
are the result of the same conditions as the three-month changes.

	Operating income decreased $1.299 million to an operating loss of $(.481)
million for the three months ended June 25, 1999 as compared to $.818 million
for the three months ended June 26, 1998, a 158.8% decrease.  This decrease is
the result of decreased sales levels and corresponding decreases in gross
profits due to fixed cost absorption at lower sales levels.  Operating losses of
$(1.330) million for the first three quarters of fiscal 1999 represented a
$3.144 million decrease or a 173.3% decrease from the $1.814 million operating
income recorded during the same period last year.

Other

In addition to the matters noted above, for the nine and three months ended
June 25, 1999, the Company recorded a $6.859 million and $3.544 million loss,
respectively, from the recognition of the Company's proportionate share of
losses of the Plug Power joint venture compared to a $27 thousand loss for
comparable periods in fiscal 1998.






              MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results during the first three-quarters of fiscal 1999 were reduced by higher
interest expense, principally resulting from increased indebtedness associated
with the Industrial Development Revenue Bonds.  The tax rate for the nine months
ended June 25, 1999 and June 26, 1998 was 1.2% and 0%, respectively.  This rate
is due to the loss generated by both continuing operations and the investment in
the joint venture and the use of net operating loss carryforwards.  However, as
a result of ownership changes in 1996, the availability of pre-1996 net
operating loss carryforwards to offset future taxable income may be
significantly limited pursuant to the Internal Revenue Code.

Financial Condition

    Working capital of $8.066 million at June 25, 1999 reflects a $2.287 million
increase from September 30, 1998 as a result of long-term financing.

    At June 25, 1999, cash and cash equivalents were $3.19 million versus $5.57
million at September 30, 1998.  Net cash used by operating activities for the
first three-quarters of fiscal 1999 amounted to $1.76 million, as compared to
cash used of $1.18 million in the prior year.  The capital used during the first
three-quarters of fiscal 1999 was applied principally to fund short term
operating cash flow requirements.  Additionally, accounts receivable decreased,
because of reduced sales, to $3.25 million or a 34.4% decrease as of June 25,
1999 as compared to $4.96 million as of September 30, 1998.

MTI also funded $4 million of previously accrued capital contributions to
Plug Power.

The Industrial Development Agency for the Town of Colonie issued $6 million
in Industrial Development Revenue ("IDR") Bonds on behalf of the Company to
assist in the construction of a new building for Advanced Products and the
Company's corporate staff and renovation of existing buildings leased to Plug
Power.  The construction project is substantially completed. The bond closing
was completed December 17, 1998 and proceeds of the IDR Bonds were deposited
with a trustee for the bondholders.  The Company has drawn bond proceeds to
cover qualified project costs.

	KeyBank issued a letter of credit for approximately $6 million in
connection with the $6 million IDR Bonds.  The KeyBank credit agreements require
the Company to meet certain covenants, including a fixed charge coverage and
leverage ratio.  Further, if certain performance standards are achieved, the
interest rates on the debt may be reduced.  The IDR Bonds and KeyBank Letter of
Credit were transferred to Plug Power effective July 1, 1999 in connection with
the sale of the MTI facility and adjacent residence.

Capital spending during the first nine months of fiscal 1999 was $2.65
million, an increase from the comparable period in 1998 where capital spending
totaled $.2 million.  Capital spending during fiscal 1999 included the
construction described above.  Total additional capital spending during fiscal
1999 is expected to be approximately $.90 million.







             MECHANICAL TECHNOLOGY INCORPORATED AND SUBSIDIARIES
                    MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Company anticipates that it will be able to meet its liquidity needs
during fiscal year 1999 from current cash resources, cash flow generated by
operations, borrowing under its existing line of credit and proceeds from the
Rights Offering completed on July 9, 1999 (see Note 12 to the financial
statements).  As of June 25, 1999, KeyBank waived certain covenant violations
and as of March 26, 1999, the KeyBank credit agreement was amended to
modify certain covenants to conform with the Company's current performance
projections.

The Company and EDC have each committed to contribute up to $22.5 million to
Plug Power to fund continuing operations through December 31, 2000.  The
Company does not have enough cash on hand to fund its commitment to Plug
Power.  If Plug Power calls all or a portion of the $22.5 million, and the
Company agrees to fund the call, the Company may attempt to finance its
capital contribution.  However, there is no assurance the Company will find a
lender or investors willing to fund the capital contribution, or that the
Company will be able to borrow or otherwise raise money on terms that are
favorable to the Company.  If the capital commitment cannot be financed and
other sources of funding are not found, the Company will not fund its full
capital commitment, and the Company's right to purchase shares of Plug Power
at the fixed price of $7.50 per share will be reduced by three times the
amount of the capital call.  If the Company does not satisfy its capital
commitment and EDC does, the Company's interest in Plug Power will suffer
substantial dilution.

Joint Venture

Plug Power, L.L.C. ("Plug Power") will continue to need substantial investment
after December 31, 1999.  Plug Power continues to pursue additional sources of
capital.  There is no assurance, however, that Plug Power will find other
sources of capital.  If other sources of funding cannot be found, the Company
will be faced with contributing and/or lending additional capital to Plug Power
or dilution of its interest in Plug Power. If EDC, the Company and other Plug
Power members stop funding Plug Power and no additional sources of capital are
found, Plug Power will not be able to continue as a going concern.

Year 2000

General

Mechanical Technology Incorporated's company-wide Year 2000 plan is proceeding
on schedule.  The plan is addressing the issue of computer programs and embedded
computer chips being unable to distinguish between the year 1900 and the year
2000 as well as the ability to recognize the leap year date of February 29,
2000.  The plan has been divided into six areas:  (1) Systems evaluation, (2)
Software evaluation, (3) Third-party suppliers, (4) Facility systems, (5)
Products and (6) Contingency plans.  The general phases common to all segments
are:  (1) Inventorying Year 2000 items, (2) Assigning priorities to identified
items, (3) Assessing the Year 2000 compliance of items determined to be material
to the Company, (4) Repairing or replacing material items that are determined
not to be Year 2000 compliant, (5) Testing material items and (6) Designing and
implementing contingency and business continuation plans for each organization
and Company location.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Systems Evaluation

All internal systems have been identified, inventoried, prioritized and assessed
for Year 2000 compliance.  Systems found to be totally non-compliant are
scheduled for replacement, the remaining systems were found to be in compliance.
Plans are being developed to ensure that staff are available to oversee
restarting certain machines and manually adjusting their dates, if needed.

Software Evaluation

All software material to the Company has been identified, evaluated, and placed
into one of three categories:  (1) Found to be in full compliance and certified
as such by vendors, (2) Identified as requiring update, or (3) Identified as
requiring replacement with compliant software. Those in the latter category have
been included in the current budget.

Third-Party Suppliers

This phase of the Year 2000 Plan is in process and will be completed by the end
of fiscal 1999.  These third-party suppliers are in the process of implementing
their own plans with an expected completion date of 1999.  If any provider is
not successfully compliant, the Company will evaluate selecting alternative
providers at that time.

Facility Systems

The facility systems review is complete.  All systems are believed to be Year
2000 compliant including telephone, fire alarm, security, elevator and network
components.

Products

The Company has evaluated both current product offerings and products in the
field to determine their ability to comply with Year 2000 issues.  The products
were found to be non-compliant, compliant if modifications are made, fully
compliant or not impacted (that is, the product does not have a computer or
contains an embedded computer but does not use a date function). Those products
identified as non-compliant are products in the field that are not Year 2000
compliant, cannot be modified and must be replaced. Products that can be
modified have upgrades available for sale.

Contingency Plans

This phase is currently being developed.  Contingency plans should be in place
by the end of fiscal 1999.

Costs
The total cost associated with required modifications to become Year 2000
compliant is not expected to be material to the Company's financial position.
The estimated total cost of the Year 2000 project is approximately $120
thousand, which includes software, hardware and cabling upgrade and replacement
costs.  This estimate does not include the Company's potential share of Year
2000 costs that may be incurred by our joint venture, in which the Company
participates but is not the operator.  The total amount expended on the Plan
through June 25, 1999 was $50 thousand for the upgrade and replacement of
hardware.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Risks

The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations.  Such failures could materially and adversely affect the Company's
results of operations, liquidity and financial condition.  Due to the general
uncertainty inherent in the Year 2000 problem, resulting in part from the
uncertainty of the Year 2000 readiness of third-party suppliers and customers,
the Company is unable to determine at this time whether the consequences of the
Year 2000 failures will have a material impact on the Company's results of
operations, liquidity or financial condition.  The Year 2000 Plan is expected to
significantly reduce the Company's level of uncertainty about the Year 2000
problem and, in particular, about the Year 2000 compliance and readiness of its
material customers.  The Company believes that, with the implementation and
completion of the Year 2000 Plan as scheduled, the possibility of significant
interruptions of normal operations should be reduced.

                              PART II OTHER INFORMATION


Item 1.  Legal Proceedings

On September 9, 1998, Barbara Lawrence, the Lawrence Group, Inc.
("Lawrence"), and certain other Lawrence-related entities ("Plaintiffs") filed
suit in the United States Bankruptcy Court for the Northern District of New
York against First Albany Corporation ("FAC"), Dale Church, Edward Dohring,
Alan Goldberg, George McNamee, Beno Sternlicht, Marty Mastroianni (former
President and Chief Operating Officer of MTI) and 33 other individuals
("Defendants") who purchased a total of 820,909 shares of MTI stock from the
Plaintiffs.  The complaint alleged that Defendants purchased MTI stock from the
Plaintiffs in violation of sections 10b, 20, 20A and rule 10b-5 of the
Securities Exchange Act of 1934.  In December 1998, the complaint was amended
to add MTI as a defendant and assert a claim for common law fraud against all
the Defendants including MTI.  The case concerns the Defendants' 1998 purchase
of MTI shares from the Plaintiffs at the price of $2.25 per share. Ownership of
the shares was disputed and several of the Plaintiffs were in bankruptcy at the
time of the sale.  FAC acted as Placement Agent for the Defendants in the
negotiation and sale of the shares and in proceedings before the Bankruptcy
Court for the Northern District of New York, which approved the sale in
September 1997.  Plaintiffs claim that the Defendants failed to disclose
material inside information concerning Plug Power, LLC to the Plaintiffs and
therefore the $2.25 per share purchase price was unfair.  Plaintiffs are
seeking damages of $5 million plus punitive damages and costs.  In April 1999,
Defendants filed a motion to dismiss the amended complaint, which was denied.
In June 1999, the parties agreed to stay discovery and amend Defendants time to
answer the amended complaint until September 17, 1999.

(b) Two reports on Form 8-K were filed during the third quarter 1999 and one
report was filed subsequent to the quarter ended June 25, 1999.

 	The Company filed a Form 8-K Report, dated March 29, 1999, reporting
under Item 5 thereof that the Company had cancelled options for 2.25 million
