August 11, 2021, Mechanical Technology, Incorporated (&ldquo;MTI&rdquo;) entered into (i) an Agreement and Plan of Merger (the &ldquo;Merger
Agreement&rdquo;) by and among MTI, SCI Merger Sub, Inc., an indirect wholly-owned subsidiary of MTI (&ldquo;Merger Sub&rdquo;), and
Soluna Computing, Inc., a Delaware Corporation (&ldquo;SCI&rdquo;), and (ii) a Termination Agreement by and among MTI, EcoChain, Inc.,
a Delaware corporation and a wholly-owned subsidiary of MTI (&ldquo;EcoChain&rdquo;), and Harmattan Energy, Ltd. (formerly Soluna Technologies,
Ltd.), a corporation incorporated under the laws of the Province of British Columbia (&ldquo;HEL&rdquo;). The Merger Agreement has been
approved by the Board of Directors of each of MTI, Merger Sub, and SCI and by Soluna Holdings US, LLC, a Delaware limited liability company
and the sole stockholder of SCI (&ldquo;Soluna Parent&rdquo;), and the Termination Agreement has been approved by the Board of Directors
of each of MTI, EcoChain, and HEL.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
purpose of these agreements is to effect MTI&rsquo;s acquisition of substantially all of the assets (other than those assets physically
located in Morocco) formerly held by HEL; such assets consist solely of SCI&rsquo;s existing pipeline of certain cryptocurrency mining
projects that HEL previously transferred to SCI (the &ldquo;Projects&rdquo;), which was formed on May 18, 2021, expressly for this purpose.
The transactions contemplated by the Merger Agreement and the Termination Agreement also provide MTI, through EcoChain, with the opportunity
to directly employ or retain the services of four individuals whose services it currently retains through HEL.</FONT></P>

January 13, 2020, EcoChain entered into an Operating and Management Agreement with HEL. Pursuant to such agreement, HEL assisted MTI,
and later EcoChain, in developing, and is now operating, EcoChain&rsquo;s cryptocurrency mining facility located in Washington State.
In that regard, on May 21, 2020, EcoChain acquired the intellectual property of GigaWatt, Inc. (&ldquo;GigaWatt&rdquo;) and certain other
property and rights of GigaWatt associated with GigaWatt&rsquo;s operation of a crypto-mining operation located in Washington State.
The acquired assets formed the cornerstone of EcoChain&rsquo;s current cryptocurrency mining operation. On October 22, 2020, EcoChain
loaned HEL $112,000 to acquire additional assets from the bankruptcy trustee for GigaWatt&rsquo;s assets. On the same day, HEL transferred
title of the assets to EcoChain, which under the terms thereof paid off the note. Pursuant to this agreement, EcoChain paid HEL $150,000
in 2020 and $118,000 to date during 2021.</FONT></P>

Merger Agreement and the Termination Agreement and the summary of their terms have been included in this report to provide investors
with information regarding their terms. Except for the status of each such agreement as the contractual document that establishes and
governs the legal relations among the parties thereto with respect to the transactions described in this report, the Merger Agreement

representations, warranties, covenants, and agreements made by the parties in each of the Merger Agreement and the Termination Agreement
were made solely for the purposes of such agreement and as of specific dates, and were qualified and subject to certain limitations and
exceptions. Moreover, the representations and warranties may be subject to a contractual standard of materiality that is different from
what may be viewed as material to stockholders and reports and documents filed with the SEC and, in some cases, they may be qualified
by disclosures made by one party to another, which are not necessarily reflected in the agreement or other public disclosures made by
MTI. Representations and warranties may be used as a tool to allocate risks between the parties to the Merger Agreement and the Termination
Agreement, including where the parties do not have complete knowledge of all facts. Accordingly, the Merger Agreement and the Termination
Agreement are included with this report only to provide investors with information regarding the terms thereof, and not to provide investors
with any other factual information regarding MTI or SCI, their respective affiliates, or their respective businesses. Neither the Merger
Agreement nor the Termination Agreement should be read alone, but should instead be read in conjunction with the other information regarding
MTI and SCI, their respective affiliates or their respective businesses, the Merger Agreement, the Merger, and the Termination Agreement
that will be contained in, or incorporated by reference into, the Proxy Statement, as well as in the Forms 10-K, Forms 10-Q, and other
filings that MTI makes with the SEC.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Matters
set forth in the exhibits to this report contain certain forward-looking statements, including certain plans, expectations, goals, and
projections, and including statements about the benefits of the proposed Merger between MTI and SCI, that are subject to numerous assumptions,
risks, and uncertainties. Actual results could differ materially from those contained or implied by such statements for a variety of
factors including: SCI&rsquo;s businesses may not be integrated into EcoChain&rsquo;s successfully or such integration may be more difficult,
time-consuming, or costly than expected; the expected benefits and cost savings from the proposed Merger may not be fully realized within
the expected timeframes; negotiations with counterparties in the projects in SCI&rsquo;s development pipeline may be disrupted by the
proposed transaction; disruption from the proposed transaction may make it more difficult to maintain relationships with customers or
vendors, and may place a burden on each of MTI&rsquo;s and SCI&rsquo;s management and internal resources; MTI may not secure the required
stockholder approvals; changes in laws, regulations, and policies, and industry developments generally, could negatively impact the cryptocurrency
mining industry or the renewable power industry, in particular, EcoChain&rsquo;s ability to purchase renewable power producers&rsquo;
and grid operators&rsquo; excess energy; adverse changes in economic or other market conditions; the short- and long-term effects of
the coronavirus pandemic, or the impacts of any future pandemics or other health crises, which are currently unknown; volatility in the
prices of cryptocurrencies; and other factors described in MTI&rsquo;s Annual Report on Form 10-K for the year ended December 31, 2020,
and documents subsequently filed by MTI with the SEC. All forward-looking statements included in this filing are based on information
available at the time of the filing of this report. MTI assumes no obligation to update any forward-looking statement.</FONT></P>

N.Y., August 12, 2021 &ndash; </B>Mechanical Technology, Incorporated (&ldquo;MTI&rdquo;), (NASDAQ: MKTY), today announced that
it and its wholly-owned subsidiary EcoChain, Inc. (&ldquo;EcoChain&rdquo;), a cryptocurrency mining business powered by renewable
energy, have entered into agreements for EcoChain to acquire Soluna Computing, Inc. (&ldquo;SCI&rdquo; or &ldquo;Soluna&rdquo;).
Upon closing of the transaction, SCI will become a wholly owned subsidiary of EcoChain (together, the &ldquo;Combined Company.&rdquo;)
The combination will allow SCI to more easily access the capital and resources necessary to scale its renewable energy-powered
data center solution more quickly and efficiently. Upon closing of the transaction, MTI plans to change its name to &ldquo;Soluna
Holdings.&rdquo;</FONT></P>

transaction will place the Combined Company into the cryptocurrency mining industry&rsquo;s large-cap peer group based on its
development pipeline</U>. Upon the closing of the transaction, MTI will gain access to all SCI assets, including its 300MW (megawatt)
pipeline that is currently under letters of intent (&ldquo;LOI&rdquo;), bringing EcoChain&rsquo;s combined total to 350MW, with
over 200MW more under active development. EcoChain will directly employ or retain Soluna&rsquo;s top-tier technical and management
team, bringing expertise in project development, energy markets, project finance and computing technology. EcoChain expects to
have 50MW operational by the end of 2021 and another 50MW by the end of the second quarter of 2022. By the end of 2022, EcoChain
expects to have two-thirds of Soluna&rsquo;s current pipeline operational.</FONT></P>

am thrilled to increase the size and scope of our company and this transaction puts us in an even stronger position to provide
significant value for investors,&rdquo; said Michael Toporek, Chief Executive Officer of MTI. &ldquo;The Soluna team has hit upon
a formula for creating and creatively financing computing facilities by solving power producers&rsquo; and grid operators&rsquo;
inherent supply and demand problems, that is, the excess energy produced but not used as a result of the mismatch between the
time of energy production, or daytime, and the time when energy use is at its highest, or evening/nighttime, which have increased
as total renewable energy production continues to grow. We believe that solving the supply and demand problem of the renewable
energy industry will serve as a driver for the growth, scalability, and profitability of &lsquo;green&rsquo; computing.&rdquo;</FONT></P>

end of September, its hash rate will have increased by 863% from July.</FONT></P>
