MIT researchers harness tree power to fight wildfires
Image Gallery (3 images)
While specialist fire-fighting crews, squadrons of trucks and water-bombing helicopters all play an important role, access to reliable and timely information on fire behavior is among the most critical of all the tools used to combat wild fires and prevent the loss of life, livestock and property damage. Massachusetts Institute of Technology (MIT) researchers are now working on a system that uses energy from the trees themselves to power a network of temperature and humidity sensors that act as remote weather stations to aid in fire management.

BioSolar's renewable backsheet for solar panels
Image Gallery (2 images)
Currently, photovoltaic modules in solar panels employ petroleum-based plastics as a protective backing, increasing their overall carbon footprint and maintaining a reliance the fossil fuel economy. To free solar power from the uncertainties of oil prices, and to help make them a truly green power source, BioSolar has developed bio-based components that are ready to replace the backsheet, substrate and superstrate components of solar panels. The materials have a lifespan of 20-25 years, and, most importantly, they are 25% cheaper to manufacture than the plastic alternative. Read More

Measuring your health in dollar terms - study shows short-term ROI of $1.17 per $1.00 spent
Image Gallery (9 images)
September 10, 2008 A program to reduce weight and improve health risk factors in obese employees produces a short-term return on investment (ROI) of $1.17 per dollar spent, according to a University of Georgia study. Just as important, the ROI model used in the study provides a relatively simple and inexpensive tool to help companies estimate the dollar benefits of investing in employee wellness programs. The ability to simulate the cost savings associated with reducing employee health risks could help in building a "credible and defensible case" for investment in employee wellness.This story really got us thinking that it might also pay for individuals to begin considering what the ROI for investing in their health would be – if there’s a short term benefit measured in dollars for your employer to pay for you to get healthy, what’s the long term ROI for investing in your optimum health with all those other personal gains to be considered – such as happiness, a feeling of well-being and a few extra years of painless mobility.

Lotus deploys unique Concept Ice Vehicle to the Antarctic
Image Gallery (5 images)
August 24, 2008 Look closely and you'll see a Lotus badge on the side of this fascinating device. Built to act as a scout to plan routes for heavier vehicles on flat, hard-packed ice, the Concept Ice Vehicle (CIV) is set to perform its first tour of duty in Antarctica with the Moon Regan Transarctic Expedition. Three oversize, suspended skis give the ultra-light CIV a low friction contact patch, and handle the steering as the biofuel-powered propeller drives the vehicle forward. Braking is another issue - a large, spiked metal arm is forced down into the smooth ice, dragging the CIV to a halt - and it comes equipped with a radar to detect hidden ice crevasses that could spell trouble for the rest of the team.
