Shower Heats Water Without Electricity

Friday, May 21st, 2010

One of the biggest consumers of electricity in a household is the hot water heater.  Old units can continuously heat water in a tank for use.  More efficient ways to heat water would be a tank-less solution that produces on demand hot water.  Even more efficient is the solar hot water heater.  The latter combined with insulated piping provides an efficient way to get hot water.  However, what if water could be heated without water heaters or solar power.  What if water could be made hot, on demand simply by turning the water on?

The Piezo Shower does exactly that.  It captures the kinetic energy of the water running through the lattice of piping to create hot water.  The idea is similar to clothing that creates energy to charge small electronic devices.  As the water runs through the pipes, the water moves piezo electric fibers that create electricity by movement and read more »

Teenager Builds Electric Car for $10K

Tuesday, October 14th, 2008

Welcome to the innovation center of electric cars…San Antonio, Texas, where Lucas Laborde built an electric car he plans on driving to school for $10,000.  He spent over 150 hours this past summer working on the car converting the gas powered kit car to an all electric car.  The Bradley GT II was the lucky conversion car that is now powered by 8 eighty pound lead-acid batteries.

Lucas’ father, Ralph Laborde, funded the project and let his son use the space at his company, River City Hydraulics Inc.  Ralph bought the kit car on Ebay for $5,000 and then spent the rest on the electrical parts and batteries that would later power the vehicle.  The converted Bradley now has a top speed of 45 mph and has a lot of low-end torque which is expected for electric vehicles.

The car does have its quirks in that the gull wing doors don’t close properly due to the stress of the 80 pound batteries twisting the fiberglass body.  However, this is a truly great accomplishment in that it takes years and several millions of dollars for auto manufacturers to come up with a working prototype.

RUF’s Electric Porsche

Friday, October 10th, 2008

The initial rumors about the German tuner, RUF, making an electric car were based on the Cayman. It is now known that the new electric platform will be based on the 911. The new electric motor will have 200 hp and a most impressive 480 lb.-ft. of torque, go 0-60 in under 7 seconds, and have a top speed of 160 mph. Like the Tesla, it will have a lithium-ion battery pack, but performance figures for the initial offering of RUF’s electric do not compare to the Tesla Roadster. The following is what we know of the Electric RUF, Tesla Roadster and Fisker Karma. read more »

Tazzari Cuts Recharge Time to 45 Minutes

Wednesday, October 8th, 2008

An Italian company, Tazzari, has taken a significant step towards resolving one of the biggest drawbacks on electric vehicles…recharging. The company claims that the Tazzari Zero will be able to get a full charge in just 45 minutes. Although not clarified, it will probably be from a 220v outlet.

The upcoming Chevy Volt will reportedly charge in under 3 hours with a 220v outlet, and similarly the Tesla Roadster will charge in about 3.5 hours. Although the Zero charges much quicker, the Tesla read more »

Record Setting Production Car To Go Electric

Wednesday, October 1st, 2008

The McLaren F1 was the fastest car in the world from 1998 to 2005 when the Koeniggsegg CCX broke that record. Then, barely a month and a half later, the Bugatti Veyron broke the mark set by the CCX at 253.81mph. The current record holder, the SSC Ultimate Aero TT pushed the mark to 256.18 almost a year ago. Now the company is setting its sight on an all new electric vehicle pushing 500bhp slated for 2009 and a 1000bhp through a 4wd system is also being considered.

This is what the press release says…

“The drive train under development will feature a revolutionary power source allowing for extended time between charging intervals with the possibility of several years between charging.”

The company is expected to roll out its first prototype in Feb ’09. The company is tight-lipped about its new battery technology, and no one on the outside knows how the car will be able to accomplish such a feat. Perhaps Fisker and Tesla should quit bickering and get to work before they get left in the dust.
