High School Kids Build What Might Be the World’s Most Efficient Electric

High School Kids Build What Might Be the World’s Most Efficient Electric Carku-xlarge
Pending confirmation by the folks at Guinness, a group of students at DeLaSalle high school in Kansas City will be able to say they’ve built the world’s most efficient electric car, a see-thru, F1-style racer that gets 300mpg equivalent.

OK, they got some help from the folks at Bridgestone America, the world’s largest tire company, who contributed resources and supplied the team with high-efficiency Ecopia EP100 tires, though the car was conceived of and developed as a class project.
The ultra light weight plug-in electric was built with the customized chassis of 2000 Lola Indy. During a recent test at Bridgestone’s Texas Proving Grounds, the car got the equivalent of 300 miles per gallon fuel economy, an amazing feat the students think qualifies for the world record. Their next project? Building a vehicle that harnesses the elusive power of the atomic wedgie.

Graphene supercapacitor breaks storage record

“Physicists have produced nanoribbons of graphene — the single-atom-thick carbon — that conduct electrons better than theory predicted even for the most idealized form of the material (abstract). The finding could help Micro-supercapacitor-prvgraphene realize its promise in high-end electronics, where researchers have long hoped it could outperform traditional materials such as silicon. In graphene, electrons can move faster than in any other material at room temperature. But techniques that cut sheets of graphene into the narrow ribbons needed to form wires of a nano-scale circuit leave ragged edges, which disrupt the electron flow. Now a team led by physicist Walt de Heer at the Georgia Institute of Technology in Atlanta has made ribbons that conduct electric charges for more than 10 micrometres without meeting resistance — 1,000 times farther than in typical graphene nanoribbons. The ribbons made by de Heer’s team in fact conduct electrons ten times better than standard theories of electron transport they should, say the authors.”

Solar Sphere Renewable Energy Source 2014

German architect André Broessel, of Rawlemon, has looked into his crystal ball and seen the future of renewable energy. In this case it’s a spherical sun-tracking solar energy-generating globe — sphearsolar11essentially a giant glass marble on a robotic steel frame. But this marble is no toy. It concentrates both sunlight and moonlight up to 10,000 times — making its solar harvesting capabilities 35 percent more efficient than conventional dual-axis photovoltaic designs.

New theory may lead to more efficient solar cells

A new theoretical model developed by professors at the University of Houston (UH) and Université de Montréal may hold the key to methods for developing better materials for solar cells.pro eric bitter
Eric Bittner, a John and Rebecca Moores Professor of Chemistry and Physics in UH’s College of Natural Sciences and Mathematics, and Carlos Silva, an associate professor at the Université de Montréal and Canada Research Chair in Organic Semiconductor Materials, say the model could lead to new solar cell materials made from improved blends of semiconducting polymers and fullerenes.
The researchers describe their findings in a paper titled “Noise-Induced Quantum Coherence Drives Photo-Carrier Generation Dynamics at Polymeric Semiconductor Heterojunctions,” appearing in Nature Communications in January 2014.
Solar cells are made out of organic semiconductors — typically blends of materials. However, solar cells made of these materials have about 3 percent efficiency. Bittner added that the newer materials, the fullerene/polymer blends, only reach about 10 percent efficiency. “There is a theoretical limit for the efficiency of the ideal solar cell — the Shockley-Queisser limit. The theory we published describes how we might be able to get above this theoretical limit by taking advantage of quantum mechanical effects,” Bittner said. “By understanding these effects and making use of them in the design of a solar cell, we believe you can improve efficiency.”

SELF CHARGING GENERATOR

MOTOR/GENERATOR runs on high voltage low current .30amp. This design is much like John Bedini that he is collecting back EMF12x12mg and capturing it and storing in the supercaps. Then reusing the electricity from supercap bank that is charged, -> down back through the circuit into a bank that is waiting to be charged. Working in this flip flop fashion the motor feeds on the magnetic force generated. Notice the faster he could turn on the reed switch the faster the device runs. Tuning the device to its resonance frequency is most important. That’s when you reach the balance of this device.

2D view of nitinol’s crystalline structure during cooling/heating cycle

Invented in the early 1959, Nitinol alloys exhibit two closely related and unique properties: shape memory and super-elasticity. Shape memory is the ability of Nitinol to undergo deformation at one temperature, then recover its original, undeformed shape upon heating above its “transformation temperature”. Superelasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the undeformed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.

Flexible Solar Cells

Critics of energy from solar panels argue that just to avert less than one-tenth of theflexible anticipated growth in coal burning by 2050, would require 200 of the Million Solar Roof initiatives launched by California’s Government. Yet, credible solar grand plans aimed at huge scale electricity generation from sun radiation actually do exist, based entirely on existing solar panel technologies assuming incremental improvements in the efficiency of current solar cells.

Going completely off grid requires more than just having solar panels for power. This PDF Provided has 206 Pages of chemical and construction guidelines and test analysis for both flexible and non flexible panel construction.

Super Capacitors Replace Car Battery

The technology is here to do away with the lead acid battery. In this video lasersaber has replaced his car battery with an array of super capacitors andsupercapacitor runs a few tests. The uses could be limitless. Solar panels could recharge these quicker than battery’s and provide greater efficiency to storing power. looking forward to seeing more Updates on YouTube from Lasersaber in regards to super capacitors.

How to Use Solar Energy to Heat your Home and Cook your Food.

Cool Solar Experiments For Home or the Classroom. To do these experiments you can get simple supply’s from recycling cardboard box’s that can come from a large appliance or old solar-hotdogfurniture box. The gesso paste, acrylic paint, paintbrush, and graph paper can be purchased at art supply stores or hobby shops. String, duct tape, masking tape, and measuring tape is available at hardware stores or if your like me around the garage. These are great inexpensive projects that will teach anyone the basics in solar heat collection and how to use it to cook food heat your room and water. It is a free download so take a look.
