Concerns over nuclear energy are at an all-time high, but the TransAtomic molten-salt nuclear reactor design could be safer, as well as cheaper.
In the 1960's Oak Ridge National Laboratory tested molten-salt nuclear reactors, but the technology was never...
True, the technology is a couple years away, but graphene-based Perforene developed by Lockheed could revolutionize desalination and water purification.
Lack of freshwater is becoming an increasingly desperate situation, typical desalination is energy intensive and expensive, but a graphene water...
In 2004, CalCars modified a standard Toyota Prius hybrid electric vehicle, not only because they could, but also to prove a point, that a plug-in vehicle could hit the 100 mpge mark.
There have always been tinkerers and inventors who tried to improve...
A solar concentrator DIY can seem like the easiest thing in the world - if someone else is doing the hard work.
A guy who calls himself "Grant Thompson" used a Fresnel lens from a dismantled old Toshiba projection TV and shows the...
London’s Mayor has revealed a £1 billion restructuring of the cycling routes in the nation’s capital. The project includes the creation of 15 miles of fully-segregated routes dubbed "Crossrail for the bike", as well as semi-segregated routes which would...
Libya is one of the world’s largest petroleum producers with annual exports of nearly $12 billion, representing 70% of total exports from the country, which also boasts reserves of crude oil estimated at about 48 billion barrels.
Even with this...
A group of astronomers attempting to determine what heats and accelerates solar wind discovered that data from an ageing NASA spacecraft might provide some clues.
Justin Kasper of the Harvard-Smithsonian Center for Astrophysics and his team of astronomers processed an...
Military vehicles are in a class all their own, and the same is true for the US Army's HUMVEE replacement, which is rated at a whopping seven miles per gallon. Actually, when you think about the Fuel Efficient Ground...
With the growth of the internet and the inherent need for data storage, NREL's new energy efficient data center makes perfect sense. Of course, who would you expect to install such a center except the National Renewable Energy Laboratory...
![Ceramic Matrix Composite [CMC] Material, Takes the Heat in a Jet Engine Core](https://i0.wp.com/www.greenoptimistic.com/wp-content/uploads/2013/03/CMCOberflaeche.jpg?resize=394%2C287&ssl=1 "General Electric Turns to Ceramics For More Efficient Jet Engine")
Jet engines run at the very edge of thermal meltdown, but General Electric is turning to ceramics to turn up the heat and make a more efficient jet engine. Jet fuel burns much hotter than even the toughest alloys,...
