Hybrid excavator promises big fuel savings

Komatsu has introduced the HB365LC-3, a 36-tonne (39.7-ton) hydraulic hybrid excavator to the European market. Compared to its diesel-only counterpart, the PC360LC-11, the Komatsu Hybrid is 20 percent more fuel efficient.Read More

Today's CO2 may become tomorrow's concrete

As carbon emissions continue to rise and cause the planet to warm up, we need to find ways to reduce them. Capturing carbon at the source of its emission is one of the solutions, but there is still the problem of storing all the carbon sucked out of the atmosphere. If that captured carbon could be put to good use, then perhaps we could have the perfect capturing system in place. This is the line of thinking that researchers at University of California (UCLA) are currently pursuing, and they have some big plans for all that carbon: turning it into concrete.Read More

Is Asia's water supply in trouble?

Based on a series of simulations ran through sophisticated computer models, researchers from MIT are highlighting the possibility that a significant percentage of the population of Asia could suffer severe water shortages by the year 2050. As a basis for the study, the team made use of a pre-existing MIT-generated computer model designed to simulate Asia's complex economic, climate, and growth characteristics. A detailed water-use model known as a Water Resource System was then introduced, and the team ran a number of simulations aiming to cover the widest range of potential scenarios.Read More

Hybrid system could clean up coal power

Even though 2015 saw the biggest decline in coal usage around the world on record according to Greenpeace, the use of the material is still thriving globally. In fact, according to the US Energy Information Administration, global coal consumption was at about eight billion short tons in 2012 (around 7.2 billion tonnes), the most recent year for which the agency provides statistics. So if coal isn't going away any time soon, what is there to do about the fuel source that is often blamed for pollution and global warming due to carbon emissions? Make it more efficient. And that's exactly what a new hybrid energy system out of MIT could do.Read More

Caribbean’s largest solar array goes online

A 33.4 MW photovoltaic solar array in the Dominican Republic has gone live this week. The installation at the Monte Plata solar facility is claimed to be the largest in the Caribbean and a planned second phase of the project is expected to take it to a capacity of 67 MW.Read More

Great Barrier Reef suffers through worst coral bleaching event on record

Scientists have warned that global warming is hurting Australia's Great Barrier Reef, but a new study has brought to light just how far along the damage might already be. An aerial survey of more than 500 coral reefs making up the system has revealed that almost all have suffered severe bleaching, with the researchers labeling it the worst mass bleaching event in the World Heritage Site's history.Read More
