Simon Dale, with the help of his father in-law, has single-handedly built this low impact Hobbit house in the woodlands of West Wales. The eco-house, which rose from a muddy hole in the ground and took three months to complete, came in at under US $5,000 (GBP3,000) – demonstrating that you don’t need to be […]
In physics, energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
Improvised explosive devices are far and away the single biggest killer of coalition troops in Iraq and Afghanistan, so the ability to identify hidden explosive threats is key to keeping soldiers safe. A team of researchers at Michigan State University has developed a tool that could detect roadside bombs from afar, using nothing more than
The rumbling you feel driving along a bridge may soon serve a purpose beyond just waking you up behind the wheel. Researchers at MIT have developed a tiny energy harvester that is able to harness low-frequency vibrations like those made by a bridge or pipeline and converting them to electricity for wireless sensors. The next
Honeywell’s wheel-shaped WT6500 takes an entirely new approach to the wind farm concept. Magnets mounted near the tips of its 20 blades sweep through an outer ring of copper coils to produce a current, making the entire wheel the generator. Because this arrangement traps energy from the fast-moving blade tips and eliminates the heavy central
Power companies across the US are aggressively rolling out the new smart meters. These new meters measure electrical consumption in real-time by being networked to electrical utilities computers. No more waiting months for meter readers to personally record your power usage. This new smart meter technology can signal you or your appliances to take certain
