Solar power in India now cheaper than electricity from fossil fuels
India is committed to solar power. The country unveiled the world’s biggest solar farm earlier this year and has quadrupled its solar capacity in the last three years. On top of that, the price of solar power has dropped 40 percent in just one year, undercutting the price of fossil fuel-generated Read More...
Tesla's solar roof tiles are now available online
Last fall, Tesla announced that it had developed solar roof tiles that can generate enough energy to fully power an entire household. Tesla’s tiles work similarly to traditional solar power cells, but are designed to blend in within traditional roofing aesthetics. Now the solar roof tiles are up Read More...
Mapped: The top 263 companies racing toward self-driving cars
Forget dot coms and social networks. The hotspot for research and investment in Silicon Valley right now is the future of transport. Convince the valley you have a new way to create a brain for a self-driving car, help people find parking, detect a drowsy driver, or build a personal electric Read More...
Power plants could cut a third of their emissions by using solar energy
Led by VTT Technical Research Centre of Finland, the COMBO-CFB project has developed a new innovative concept to increase solar energy production in the energy system. According to this research, the concept can reduce fuel consumption and emissions stressing the climate by more than 33 percent. Read More...
Biofuels: could agave, hemp and saltbush be the fuels of the future?
Biofuels have long been touted as a carbon-neutral alternative to fossil fuels, doing for the world’s planes, ships and automobiles what windfarms and solar panels are doing for its electricity grids. With the transport sector accounting for almost one fifth of Australia’s total carbon Read More...
Study: By 2030, self-driving cars could cut car ownership by 80 percent
Stop us if you've heard this one before: someone's published a study on self-driving cars and the effect they'll have on transportation. In the past year alone, we've seen plenty of those studies. Some show that people are afraid of self-driving vehicles (even though they're totally onboard with Read More...
New technology recycles wastewater into hydrogen for use in fuel production
"Electrical" bacteria are the key ingredient in a new process developed by the Department of Energy's Oak Ridge National Laboratory that recycles wastewater from biofuel production to generate hydrogen. The hydrogen can then be used to convert bio-oil into higher grade liquid fuels such as gasoline Read More...
Possibility: Drones for peace
From The Intelligent Optimist Summer 2016 Imagine for a moment that a child is critically ill in a small village weeks away from any hospital. With no quick means of transportation, the child’s worried doctor picks up the phone or sends a text and, in a matter of hours, the much-needed medical Read More...
Possibility: Windmills under the sea
From The Intelligent Optimist Magazine Fall/Winter 2016 There’s enough wave energy in the oceans to power the world, and scientists and businesses are finally close to harnessing it. For decades wave energy has lagged behind wind energy and solar because harnessing it is more complex. But for Jim Read More...
These new wind-energy technologies look incredible
Many consider modern windmills eyesores in the landscape despite their obvious clean energy benefits. A new generation of wind technologies are on their way, and they not only promise to make wind energy safer and more affordable, their sleek designs are also stunning. See this series of new Read More...
