Rice University scientists combined graphene quantum dots drawn from common anthracite coal with graphene oxide, nitrogen and boron into a catalyst for fuel cells that outperforms the expensive rare earth platinum. In a fuel cell application the graphene quantum dots grab onto graphene platelets like barnacles attach themselves to the hull of a boat. The [...]

Scientists at the Center for Research in Advanced Materials (CIMAV) have developed a device that fits inside a pair of shoes that harvests the energy made available when someone walks. This energy is then stored in AAA or watch batteries. The team designed a pill-shaped cylinder adapted to a shoe in order to store the [...]

A study by a team from the Institute of Vehicle Concepts, German Aerospace Center (DLR) on the total cost of ownership (TCO) strongly suggests car manufacturers should develop a modular battery design for plug-in hybrid and extended range electric vehicles (PHEVs and EREVs). That simple change would allow consumers a choice of storage capacity to [...]

A University of Wisconsin team led by Professor Rolf Reitz has designed a hybrid fueled engine using both diesel fuel and gasoline that is 59.5% efficient. Chemical efficiency at 59.5% is far better than gasoline engines and 10 to 15% better than the 52% maximum in modern diesel truck engines. Professor Reitz is one to [...]

The GoTek engine is actually quite simple and a puzzle when just looking at the line drawings. With a read of the patent it can be explained simply. GoTek Energy has their patent issued and the press, including some major media have noticed, including some of those line drawings to confuse folks. This is an [...]
