Alumni Spotlight: If You’re in a Jam, Dick Hembree’s Your Man

His Inventions Have Saved Lives and Attracted Worldwide Attention

Despite being an inventor who holds 22 patents in the United States (U.S.)—and many more globally—Richard "Dick" Hembree (BEng'83) doesn't consider himself to be creative.

Dick is a born adventurer who loves flying and sailing.

"I see something that doesn't work, or doesn't do its job very well, and I think of a better way of doing it," says Dick, who lives in Port Coquitlam, British Columbia.

"A patent has to be useful, non-obvious, and unique, and most of the things I come up with are like that. It always starts with a problem I want to solve rather than a dream I want to accomplish."

A Daring Designer

Growing up in Burnaby, British Columbia, Dick always had hobby projects on the go.

"My dad was a do-it-yourself type of guy—he grew up on a farm and fixed things all the time, and as a young kid, I was taking things apart and making them do things they weren't made to do," he recalls.

"When I was 10, I made a little motorized contraption to close the drapes in my room—silly stuff like that."

In high school, he decided to become an automotive mechanic and machinist.

Long-time friend Don Middleton says he's always admired the way Dick's mind works.

"In high school, my neighbour gave us a compressor from a refrigerator, and we actually thought we could snorkel underwater with this as a breathing apparatus, but it was a big failure," he laughs.

"But that didn't stop Dick from carrying on. We altered a small open sailboat and added a 'cuddy cabin' so we could sleep in it and then sailed over to Vancouver Island. His bravery allowed him to tackle anything.

At 17, he tried to rejig and adapt a Volkswagen into a sports car. He was the kind of guy that would rip the whole body off and make a new one out of fibreglass."

Lakehead Lays the Groundwork

After graduating magna cum laude from the British Columbia Institute of Technology (BCIT) with a diploma in mechanical technology in 1979, he was recruited by Canada's Defense Research Establishment Pacific (DREP) in Esquimalt, British Columbia, as a technologist.

At DREP, he designed and built mechanical equipment used in ocean acoustic research.

"We had our own little engineering group, so I was machining parts and designing things like experimental underwater acoustic listening devices, pressure-vessel equipment with electronics, winches, and other equipment for ships," he says.

But while Dick enjoyed the work, he felt he could lead the design team, rather than follow other people's ideas, so after two years at DREP, he enrolled in Lakehead's post-diploma engineering degree program.

"One personal philosophy that has evolved over my life is that you should never stop learning," Dick says.

"Lakehead was one of my best choices because it had a good mechanical engineering transfer program for BCIT graduates, and it felt like a good fit for me," he says.

"I enjoyed those Lakehead years, and the professors were very good.

At BCIT, we learned about the practical application of science, but at Lakehead we went more deeply into the use of differential equations, which I found really interesting.

In high school, I never was able to connect the dots and see what I would do with things like calculus, but I felt that connection at Lakehead."

Creating the World's Smallest Seawater Desalinator

After graduating with first class standing, Dick was ready for a new chapter.

"I felt like I could get into any field and enjoy it. I wanted to design things, and I was interested in manufacturing and engineering," he says.

Dick was intrigued by Vancouver-based Seagold Industries, which was testing a hand-operated desalinator.

"I liked the idea of making drinking water from seawater with a little hand pump, and I was impressed with the concept of it, so I contacted the company and told them I thought I could add something to it," he recalls.

"They hired me."

As Seagold's newest design engineer, Dick did much more than just add something to it.

Working with their basic, larger pump, he designed the world's smallest seawater desalinator and became a leading global expert in the process.

Dick designed, developed, and put into production the first hand-powered pumps to purify seawater for use on life rafts, ships, and planes.

Seagold's reverse-osmosis water purification devices use energy-recovery technology, which allows users to purify seawater with little effort.

With Dick's input, the company quickly attracted the attention of the U.S. Air Force, which asked him to design a small desalinator to fit into its two-by-six-by-eight-inch ejection seat survival kits.

Soon afterwards, Minneapolis-based Wanner Engineering acquired Seagold's patents, installing Dick as chief engineer of their new spin-off company, Recovery Engineering, in 1986.

His new task: Designing and developing a small hand-operated desalinator for the U.S. Navy's 25-man life rafts.

"There were very few people working on hand-operated desalinators; that's why it was so unique to have a small one," Dick says.

"It was pretty scary at first; I was still a little inexperienced and suddenly I was doing a proposal for the U.S. Navy.

Then I designed a motorized version we could sell commercially and that did fairly well—it was the only 12-volt low-powered desalinator on the market."

Shipwreck Victims Survive Pacific Ocean Disaster

In 1989, a few years after Dick's team started Recovery Engineering, a Florida couple on an around-the-world voyage had their boat capsized by a school of pilot whales, forcing them onto their lifeboat.

Bill and Simone Butler were adrift for 66 days in the Pacific Ocean before they were miraculously rescued 1,200 miles off the coast of Costa Rica.

They couldn't have survived that long if it weren't for Dick's invention—the Recovery Survivor-35 pump—which extracted three litres of freshwater from the ocean every day until they were rescued.

Coverage on CBS, People Magazine, and other news outlets boosted the company's reputation and its sales.

"I remember getting phone calls from people telling me to watch the news. There was a photo of the Butlers holding up the desalinator after their rescue. That notoriety really helped us build the company."

Procter & Gamble Come Calling for Dick's Water Purifiers

Dick went on to develop desalinators for other countries along with a line of hand-operated and low-power desalinators for a brand-new market—the recreational marine consumer.

From there, he designed and patented the first hand-pumped outdoor backpacking water purifiers under the PŪR brand and household faucet-mounted filters that sold so well, Procter & Gamble (P&G) bought the company in 1999.

Seeking consumer products with the potential for rapid growth, P&G hired Dick as the research and development director of their water purification division.

They were impressed by the way he had built up his engineering group from two to 500 employees, as well as his product-development processes.

Dick invented and patented the first hand pumps for hikers and backpackers so that they could purify water taken from lakes and streams.

"It's funny, I consider myself more of a mechanical designer than a water purification expert, but when I looked into what was on the market, the breakthrough came when I realized that companies couldn't make good on the claims of their household water purifiers to reduce lead levels," he says.

Dick discovered that by incorporating an end-of-life indicator into the purifier, the purifier could track how many gallons go through its filter and accurately measure chemical reduction levels.

"By doing that, we were able to get NSF (National Sanitation Foundation) International certifications."

By 2001, Dick's role had become more administrative, so he left P&G to form his own consulting firm.

He also became a major contributor to Wanner Engineering's unique high-pressure pumps and valves, which were designed to handle complex fluids for the oil and gas industries.

Always Keep Your Curiosity Alive

Dick's love of hobbies has never waned—he is an avid skier, and he piloted his own airplane for 10 years.

"I've sailed all my life, too," he says.

Dick's most important tip for young engineers and would-be inventors? Always stay curious.

"It's nice to specialize and get good at something, but it's amazing how much you can learn by delving into completely different areas.

Electronics has always been one of my passions, and although I'm not formally trained in it, I've learned to program in several languages and build things run by microprocessors I've programmed.

And when I hire employees, I look for people who have hobbies."

 

Professors from Lakehead and Villanova universities are studying fish to create underwater robots

December 18, 2023 – Thunder Bay, Ont.

A Lakehead University professor and a professor from Villanova University are studying how fish use navigation and propulsion to help them create underwater robots, thanks to funding from NSERC.

Dr. Muhammad Khalid, Assistant Professor in Mechanical Engineering, received a $25,000 Alliance International Catalyst Grant from the National Sciences and Engineering Research Council of Canada for his project to build an international research partnership with Dr. Chengyu Li from Villanova University, and jointly investigate fluid-structure-chemical interactions in marine environments.

Over one year, they will study the “mysterious but very effective techniques adopted by fish in natural aquatic conditions,” Dr. Khalid said.

“These fish will provide us with lessons to design and develop efficient, agile, stealth, and highly maneuverable underwater robots.”

“We will study how fish sense the presence of predators, prey, food, and mating partners through fluctuations in velocity and pressure in the surrounding water. We want to learn how odour signatures and chemical cues help fish navigate in complex underwater environments,” he said.

The researchers will study how different fish, for example carangiform (Jack Fish, Tuna, Salmon), and anguilliform (eels), effectively control fluid dynamics through their kinematics to send and receive chemical cues.

They will investigate how natural aquatic swimmers use chemical odours for their navigation and propulsion.

Fish use these elements as important natural sensing and detection methods, but they are still relatively misunderstood by the scientific community.

Using the basics of natural swimming to design fish-like underwater robotic platforms form the main goals of this project. The researchers will develop mathematical models and perform computational simulations to investigate and understand odour-guided propulsion of fish-like bodies.

“The findings of this project will reveal important leads for developing bio-inspired techniques and equipment for sensing, detection, navigation, and propulsion of highly interdisciplinary underwater robots,” Dr. Khalid said.

The success of this project is expected to bring the Canadian scientific community and marine engineering industry at the forefront of environment-friendly underwater engineering technologies for a variety of purposes.

These include securing the borders, subsea explorations for natural resources, rescue and search operations, and several other opportunities.

In 2022/23, Lakehead University received more than $2 million in assistance from the Research Support Fund to support the indirect costs of research, which includes costs for supporting the management of intellectual property, research and administration, ethics and regulatory compliance, research resources, research facilities, and research security.

April 6, 2016 – Thunder Bay, ON

A fourth-year Mechanical Engineering student from Lakehead University placed first at the Canadian Engineering Competition held recently at McGill University.

In the Engineering Communications category, Andreas Zailo had to present a clear and concise viewpoint on a technical topic to a judging panel. He had to focus on thoroughly explaining technical, social, economic and environmental impacts.

Zailo chose to research the impacts of Net-zero Geothermal Greenhouses for remote and Isolated Communities in Northern Canada for his project. While he entered as an individual, his topic came from his degree project work and he credits his teammates Alex Coulson, Evan Oulahen and Tyler Beckie, and his supervisor Dr. Basel Ismail for helping him prepare for the competition.

“Basically my presentation covered the engineering processes and technologies that were combined and optimized to create a thermally stable growing platform for year-round food production,” Zailo said.

“Afterwards, I had to outline the social, economic and environmental concerns and impacts,” he said.

Zailo first competed at the locally held Lakehead Engineering Competition (LEC) that allows students to enter four categories: Junior Design, Senior Design, Software/Programming, and Engineering Communications. Winners moved on to the Ontario Engineering Competition (OEC) and, ultimately to the Canadian Engineering Competition (CEC) if they continue to place first or second.

In addition to placing first at the OEC against 16 other Ontario universities, Zailo also received the Social Awareness Award. 

Dr. David Barnett, Dean of the Faculty of Engineering at Lakehead University, congratulated Zailo on his accomplishment and noted the “importance of communication skills in the development of a successful engineer.”

The annual CEC competition held in March brought together students from across Canada who have advanced to the national event following local and regional competitions.
