Porsche 911 GT3 R with a mechanical flywheel battery

The mechanical flywheel battery is charged by applying the front brakes. The flywheel is spun up from the brake energy and remains spinning until energy is needed. The flywheel spins at up to 40,000 rpm and this is how the kinetic energy is stored. Apparently, this is very efficient compared to chemical batteries.

When needed, the flywheel battery is slowed electromagnetically and generates up to 120 kW of electricity for the two front electric motors. It can do this for up to 8 seconds before it needs to be charged again.

I really like this kinetic energy battery instead of chemical. I think it would last longer and shouldn't degrade in performance like chemical batteries do over time.

It reminds me of those toy cars that I used to play with as a kid where you have to push it along the floor several times to spin up the internal flywheel and then push the button to send it zooming off like a missile on wheels!

This Porche is so cool, the only question is when can I buy one? I hope this technology spins off from racing to more affordable hybrid cars that people can actually buy.

Hidden Costs of Slow Computers

Saving a few dollars on that new computer for your business may end up costing more than you know…

A slow computer will cost (over time) many times what a productive new computer would cost at the beginning. It’s not the easiest thing to see since I’m talking about indirect costs. It’s the little things, repeated over and over that add up to a lot of time wasted if the user has to wait even a little for each task. 

Not only is train of thought interrupted sitting there staring at the computer screen that is doing nothing but causing immeasurable damage to the user’s creative and intelligent thought process. This cost is tremendous on the business as a whole because of lost potential by stifling the human ability to be “on-a-roll” and in the work groove. 

 

Everyday tasks that a user would issue to a computer and that are direct causal events of lost productivity:

  • send/receive email
  • open/close programs
  • restarting
  • freezing (usually caused by user impatience with the computer)
  • visiting websites

 

Possible indirect effects on a business due to computer sluggishness:

  • customers are forced to wait and customer satisfaction decreases
  • employees don’t live up to their full potential as described above
  • less work gets accomplished in general
  • more dollars spent on computer repair (break/fix) and more computer downtime
  • lower employee job satisfaction and enthusiasm (this can have a major negative effect in many areas)
  • higher employee turnover and similarly, lower average experience per employee
  • higher risk of data loss stemming from computer problems (slower computers have more problems in part from user impatience)
  • higher level of business debt, more past due A/R, and a bigger pile of accounting in the "to do" bin

 

In my opinion, this can all be attributed to slow computers.

It’s my job to provide experienced consulting to people about what to buy and where to spend money to save money. It gives me great pleasure to make a business more productive, their life easier, and ultimately put more money in their pockets.
