CONTINUING AND UNCONDITIONAL GUARANTY

Exhibit 10.4

Bank of America

1. The Guaranty. For valuable consideration, the undersigned ("Guarantor") hereby unconditionally guarantees and promises to pay promptly to Bank of America, N.A., its subsidiaries and affiliates (collectively, "Bank"), or order, in lawful money of the United States, any and all Indebtedness of Mechanical Technology, Incorporated ("Borrower') to Bank when due, whether at stated maturity, upon acceleration or otherwise, and at all times thereafter. The liability of Guarantor under this Guaranty is not limited as to the principal amount of the Indebtedness guaranteed and includes, without limitation, liability for all interest, fees, indemnities, and other costs and expenses relating to or arising out of the Indebtedness and for all swap, derivative, foreign exchange or hedge or other similar transaction or arrangement ("Swap Obligations") now or hereafter owing from Borrower to Bank. No Guarantor will be deemed to be a guarantor of any Swap Obligation to the extent that such Guarantor is not an Eligible Contract Participant at the time such guaranty becomes effective with respect to such Swap Obligations as set forth in the Commodities Exchange Act (7 U.S.C., Sec. 1, et. seq.). The liability of Guarantor is continuing and relates to any Indebtedness, including that arising under successive transactions which shall either continue the Indebtedness or from time to time renew it after it has been satisfied. This Guaranty is cumulative and does not supersede any other outstanding guaranties, and the liability of Guarantor under this Guaranty is exclusive of Guarantor's liability under any other guaranties Signed by Guarantor. If multiple individuals or entities sign this Guaranty, their obligations under this Guaranty shall be joint and several. "Indebtedness" shall mean and includes any and all advances, debts, obligations and liabilities of Borrower, or any of them, previously, now or later made, incurred or created, whether voluntary or involuntary and however arising, whether due or not due, absolute or contingent, liquidated or unliquidated, determined or undetermined, including Swap Obligations and obligations under any deposit, treasury management or other similar transaction or arrangement, and whether any of the Borrowers may be liable individually or jointly with others, or whether recovery upon such Indebtedness may be or later becomes unenforceable.

2. Obligations Independent. The obligations under this Guaranty are independent of the obligations of Borrower or any other guarantor, and a separate action or actions may be brought and prosecuted against Guarantor whether action is brought against Borrower or any other guarantor or whether Borrower or any other guarantor be joined in any such action or actions.

3. Rights of Bank. Guarantor authorizes Bank, without notice or demand and without affecting its liability hereunder, from time to time to:

(a) renew, compromise, extend, accelerate, or otherwise change the time for payment, or otherwise change the terms, of the Indebtedness or any part thereof, including increase or decrease of the rate of interest, or otherwise change the terms of any Bank Agreements;

(b) receive and hold security for the payment of this Guaranty or any Indebtedness and exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any such security;

(d) release or substitute any Guarantor or anyone or more of any endorsers or other guarantors of any of the Indebtedness; and

Continuing and Unconditional Guaranty

(e) permit the Indebtedness to exceed Guarantor's liability under this Guaranty, and Guarantor agrees that any amounts received by Bank from any source other than Guarantor shall be deemed to be applied first to any portion of the Indebtedness not guaranteed by Guarantor.

4. Guaranty to be Absolute. Guarantor agrees that until the Indebtedness has been paid in full in immediately available funds and any commitments of Bank or facilities provided by Bank with respect to the Indebtedness have been terminated, Guarantor shall not be released by or because of the taking, or failure to take, any action that might in any manner vary, discharge or otherwise reduce, limit, or modify Guarantor's obligations under this Guaranty. Guarantor waives and surrenders any defense to any liability under this Guaranty based upon any such action, including but not limited to any action of Bank described in the immediately preceding paragraph of this Guaranty. It is the express intent of Guarantor that Guarantor's obligations under this Guaranty are and shall be absolute and unconditional. If this Guaranty is revoked, returned, or canceled, and subsequently any payment or transfer of any interest in property by Borrower to Bank is rescinded or must be returned by Bank to Borrower, this Guaranty shall be reinstated with respect to any such payment or transfer, regardless of any such prior revocation, return, or cancellation; and any guaranty of any indemnities, shall survive any termination of this Guaranty. In the event of the death of a Guarantor, the liability of the estate of the deceased Guarantor shall continue in full force and effect as to (i) the Indebtedness existing at the date of death, and any renewals or extensions, and (ii) loans or advances made to or for the account of Borrower after the date of the death of the deceased GUarantor pursuant to a commitment made by Bank to Borrower prior to the date of such death. As to all surviving Guarantors, this Guaranty shall continue in full force and effect after the death of a Guarantor, not only as to the Indebtedness existing at that time, but also as to the Indebtedness later incurred by Borrower to Bank. In the event that acceleration of the time for payment of any of the Indebtedness is stayed upon the insolvency, bankruptcy, Of reorganization of Borrower or otherwise, all such Indebtedness guaranteed by Guarantor shall nonetheless be payable by Guarantor immediately if requested by Bank.

(c) until the Indebtedness has been paid in full and any commitments of Bank or facilities provided by Bank with respect to the Indebtedness have been terminated, even though the Indebtedness may be in excess of Guarantor's liability hereunder, to the extent permitted by applicable law, any right of subrogation, reimbursement, indemnification, and contribution (contractual, statutory, or otherwise).

No provision or waiver in this Guaranty shall be construed as limiting the generality of any other waiver contained in this Guaranty.

6. Lien and Setoff. Guarantor grants to Bank a continuing lien, security interest, and right of setoff as security for all of Guarantor's liabilities and obligations to Bank, whether now existing or later arising, upon and against all the deposits, credits, collateral and property of Guarantor (other than clients' trust and other fiduciary accounts or escrows) now or hereafter in the possession, custody, or control of Bank or any entity under the control of Bank of America Corporation and its successors and assigns or in transit to any of them. At any time, without further demand or notice (any such notice being expressly waived by Guarantor), Bank may set off the same or any part thereof and apply the same to any liability or obligation of Guarantor even though unmatured and regardless of the adequacy of any other collateral securing this Guaranty.

If any payments are received by Guarantor in violation of such waiver or agreement, such payments shall be received by Guarantor as trustee for Bank and shall be paid over to Bank on account of the Indebtedness, but without reducing or affecting in any manner the liability of Guarantor under the other provisions of this Guaranty.

Such revocation shall be effective upon actual receipt by Bank, at the address shown below or at such other address as may have been provided to Guarantor by Bank, of written notice of revocation. Revocation shall not affect any of Guarantor's obligations or Bank's rights with respect to transactions committed or entered into prior to Bank's receipt of such notice, nor shall it affect Guarantor's obligations with respect to any indemnities, executed prior to Bank's receipt of such notice.

(b) Guarantor acknowledges and agrees that this Guaranty may be revoked only in accordance with the foregoing provisions of this paragraph and shall not be revoked simply as a result of any change in name, location, ownership or composition or structure of Borrower, or the dissolution of Borrower.

15. Remedies.
