Weed-Killing Lasers in Your Garden?
The key to successful gardening is weed and pest control. Currently that task falls to either manual labor or through the magic of chemistry. Those two methods are also the hallmark of successful farming as well. A recent ASME article profiled an autonomous weeder introduced by company located in the northwest US, Carbon Robotics. This weeder is […]
Around the World via Solar, Wind and Hydrogen
There are three technologies that are changing the designs of modern ships: solar, wind, and hydrogen. A fascinating CNET video describes a research vessel that is using all three technologies to achieve a fully self-sustaining travel. It is called the “Energy Observer.” Solar panels collect energy from the sun during the day and then it is […]

Does the Earth Have a Pulse?
It’s been assumed that major geological events such as volcano eruptions and sea level change are random and may be a result of entropy, and there is no pattern to these events. According to a SciTechDaily article, NYU researchers plotted the number of major geological events for the last 260 million years and the simple […]
Like Floating a Bus on a Tall Pole
Offshore wind turbines have to date been mounted on foundations resting on the bottom of the ocean. This design best resists the forces from wind and waves. Currently the deepest this design can be used is 60 meters. This puts 60% of the US’s offshore sites out of reach. One solution is to mount the wind turbine on a […]

You go to the grocery store and buy food, take it home and prepare meals, and store perishables either before or after they are cooked in the “frig.” But what about the food the astronauts eat? Up to now, from the beginning of the space […]
