A similar patent was also filed jointly with Mr. Liknes and a company called Northern Pressure Systems Ltd. in 2001. One of the shareholders and directors of that company was Dick Bonnycastle, who operated Harlequin Enterprises before it was sold to the Toronto Star.
Mr. Bonnycastle told the National Post that he vaguely remembered Mr. Liknes, but the inventor hadnt been involved with the company for about a decade. The pump was built, but never proved to be economically viable. Investment was further stalled when natural gas prices tanked in 2008. Northern Pressure Systems went dormant.
