         <description><![CDATA[With Nissan unveiling an electric car iPhone app before the actual electric car, I thought I would add a link to all the latest electric car happenings as seen on Engadget.&#160; Of particular interest is MIT’s rapid charge program that aims to strap almost 8000 lithium iron-phosphate batteries to an AC induction motor.&#160; They seem to think they can get a full charge in 10 or so minutes.&#160;]]></description>

         <description><![CDATA[It's here, and I've been waiting some time for this.&#160; Smarthome just picked up an inexpensive whole house power consumption meter.&#160; The device consists of a strap-on sensor/transmitter for your outdoor meter and a wireless receiver.&#160; After a short calibration, the display unit will tell you the current usage in kW and the cost based on your electric provider's rate.&#160; It will also sum the usage over the period of time since you last reset the device.&#160; All for about...]]></description>

         <description><![CDATA[Not that I advocate the end of Christmas, but one benefit is the dramatic price reductions of Christmas lights, specifically LEDs.&#160; I managed to find the saturday supersaver price on a set of white LED lights for around $10 (although I heard the 75% off sales had them down to $3).&#160; My plan is to make a lamp.&#160; Here is what you need.&#160; 1) A set of LED Christmas lights 2) a light socket adapter 3) and a lamp and shade.&#160; Bunch the LED lights up with a rubber band and plug...]]></description>

         <description><![CDATA[The solar water heater has been a staple in places like Tel Aviv since I can remember.&#160; Few residents (except in the high rises) actually use electricity to take a hot shower.&#160; But for some reason, this technology has been completely unused here in the States, so much so that it is difficult to even find a solar unit.&#160; But in an example of how regulation can jumpstart innovation and technology, Hawaii has issued legislation requiring all new homes to have solar water heaters...]]></description>

         <description><![CDATA[






     




In the late 80's and early 90's, I was an advocate of big nuclear power plants.&#160; Back then, the major concern was over nuclear accidents, radiation, and meltdowns.&#160; We learned enough in engineering school to understand the operations of those plants and the safety mechanisms in place to prevent accidents with repercussions.&#160; The anti-nuclear activists leveraged the fear factor to quash most of the nuclear building plans back then. &#160;
Today nuclear power is...]]></description>

         <description><![CDATA[I met Mr. Ron Williams today.&#160; He is the energy manager for NASA Johnson Space Center.&#160; They had a booth promoting conservation so I stopped by and asked why JSC leaves virtually all of their lights on 24 hours a day.&#160; The problem, apparently, comes down to the lack of breakers.&#160; When most buildings were built, only limited breakers were installed.&#160; This is unfortunate, he admitted, because it drastically reduced the number of timers they could install.&#160; They do...]]></description>

         <description><![CDATA[If we can provide an inexpensive method for the average consumer to monitor home power usage, I expect a reduction in consumption.&#160; A simple photoelectric receiver monitoring a standard meter can easily provide this.&#160; Tie it to a wireless transmitter and you have an inexpensive reporting system for the common household.&#160; From there it is simple to input the electric company rate and get a real-time dollar per hour amount.&#160; I envision a basic LED display that reports current...]]></description>

         <description><![CDATA[Ohio State researchers have synthesized a new solar cell material that is capable of capturing solar energy over the whole spectrum of visible light.&#160; The material excites the electrons off the atoms in two states, dubbed singlet and triplet.&#160; The great news here is that the electrons in the triplet state are free from their atom for significantly longer, allowing the cell to marshall them into the array train.&#160; This could result in significantly higher efficiency ratios.&#160;]]></description>

         <description><![CDATA[I'm going to start this log with what is perhaps the best news I've heard this year.&#160; The National Renewable Energy Laboratory (NREL) has announced they have achieved an efficiency of 40.8% conversion for their latest gallium arsenide solar panels.&#160; While the exact design is not known to me, they appear to have made the jump using a spectrum approach in the manufacture approach.&#160; This is good news as manufacture is cheaper, in the long run, than materials.&#160; And since the...]]></description>
