DesignLine hybrid and electric buses:
DesignLine is a leading manufacturer of hybrid and electric buses that offer significant environmental and cost advantages over traditional diesel vehicles. Designline is best known for its hybrid buses, running on battery power and with a small gas turbine engine and generator to keep the battery charged. The DesignLine bus nearly doubles the fuel efficiency of a 40 foot bus, compared against traditional diesel vehicles.
A recent, multi-year study conducted by the company showed that its Enhanced Electric buses in operation in the Charlotte Douglas International Airport showed increases in fuel economy of up 41% and maintenance cost reductions up to 93% when compared to the airport’s traditional diesel buses.
The DesignLine Enhanced Electric Bus is unique in the transit industry. It is a pure electric vehicle with an on-board range extender used solely to recharge batteries throughout the day. In addition to the fuel and maintenance savings, DesignLine’s Charlotte Airport buses reduced NOx emissions by 42% and CO emissions by 38% during daily operations according to Mecklenburg County’s Air Quality Division.
Solar resource assessment (How much solar radiation can be typically expected?) and forecasting (How much solar radiation can be expected in the next hour or next day?) are critical to expanding the penetration of solar power on the electric grid. Jan Kleissl at UCSD has a demonstration system that could be expanded to the whole country. SPIE video: http://spie.org/x43674.xml
We need to develop more Co-Generation methods that exploit the inefficiencies of one process to power another.
We need to find a process that can convert low Delta T heat (such as off the back of a solar panel or the exhaust heat from a server farm) into a form of energy that can be exploited. Maybe it can be used to accelerate algae growth or some fuel producing biomechanism.
doesn't a chip consumes power on demand?
I mean, if the computer is only browsing the web for emails I assume it will not consume that much power.
It will if it's downloading video or playing a video game right?
1. Solid state lighting (specifically LED technology), especially the next-gen products that will go beyond the replacement of Edison bulbs and fluorescent tubes.
2. The development of SiC (silicon carbide) power semiconductor switches & diodes with the potential to create ultra-high efficiency power inverter systems.
3. Energy harvesting through new thin-film thermoelectric materials technology.
4. Distributed control systems for building lighting (solid state or otherwise) that enable energy-efficient lighting control through IP-addressable nodes.
5. Fast-charging electric vehicle connectors (and the attendant electronics technology) that will enable electric vehicles to be charged from regular 100V outlets.
A Book For All Reasons Bernard Cole1 Comment Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
