I attended an interesting meeting this morning (that I thought might be interesting to the group):
North Texas Renewable Energy Group
`Valley Ranch Library, Irving
401 Cimarron Trail
Darius Tasario - CEO Helios Electric - http://www.helioselectric.com
There were 18 people -it was a very interactive audience.
Parallel Hybrid - gas and electric engine and either drive the wheels
Conversions - about 4000 on streets in America now - about $30k to make conversion - just lots of torquecompared with a gas enginer.
Series Hybrid - gas and electric engine but only the electric drive the wheels
Average: 250 Watt hours per mile for electrical vehicles
Average: 150 Watt hours per mile for solar energy vehicle (60 square feet of cells)
Lithum batteries charges 3000 times - Lead batteries charges 600 times
Charge station - 30 minutes fast charge - 4 or 5 in Dallas - newest one is at Half Priced Books on Northwest Highway - there will be 100 in Dallas by June ("Ego energy" as part of the economical stimulus package)
Electric Vehicles are limited to 600 Volts (anything higher requires a lot of safety per NEC Code)
AC Drives are more efficient since higher voltage and easily allows regeneration
Fuel cells / super capacitors -> next technologies are on the way.
Corvettes make a good conversion - size - aerodynamics - parts readily available
Air conditioners are only 500 Watts, heaters are 1kW to 2kW
Solar cars less than 600 pounds to travel 60 to 80 MPH
The North Texas Electric Car Club was mentioned (Brian was noted as very helpful)
