Reimagining the Automobile Industry by Selling the Electricity

Posted October 29, 2007 9:36 AM

From NYT > Technology:

A top Silicon Valley technologist has devised a plan to reinvent the auto industry around electric-powered cars by building battery-charging stations around the world. Shai Agassi, a Silicon Valley technologist who was in competition to become chief executive of SAP, one of the world's largest software companies, has re-emerged with a grand plan to reinvent the world's automobile industry around battery-powered all-electric cars. Others are developing green cars, like the Tesla and Chevrolet Volt. However, Mr. Agassi is not planning to make cars, but instead wants to deploy an infrastructure of battery-charging stations in the United States, Europe and the developing world. The new system will sell electric fuel on a subscription basis and will subsidize vehicle costs through leases and credits. "We're basically saying this is just like the cellular phone model," he said. "If you think of Tesla as the iPhone, we're AT&T." On Monday, he plans to announce in New York City that he has raised $200 million from private venture partners, including the Israel Corporation, a large Israeli transportation and technology holding company, Vantage Point Venture Partners, as well as a group of private investors including Edgar Bronfman Sr., the liquor magnate, and James D. Wolfensohn, former head of the World Bank. Israel Corporation's $100 million investment was announced earlier this year.

The dream is a real one I am telling you.

My fantasy / engineering exploration in that direction involves local land owners with fences. You place one half mile of solar collectors along their fence. They get their juice for free, and you get to sell the rest with a automated credit card / meter machine.

Place a little park for kids and dogs you could make lots of bucks I bet.

I Dun Know why any would need to put power collectors in Space. The possibilities here on the Terra Firma just boggle the mind

Because in earth orbit, there is much more sunlight than at the best site on earth. My recollection was something like 20 - 25 times what Phoenix or Tucson would get. Further, it is available 24/7 at full strength, minus a few percent for eclipses. Collecting in space, sending to earth by microwave to rectennas was shown to be roughly 60% efficient when tested back about 25 years ago, and should be better now. And rather than whine about low efficiencies of solar cells, imagine using a "steam" powerplant (whatever the actual chosen working fluid): the solar array become mirrors & tubes, and the collection efficiency is now high. Steam is used to power a conventional turbine & generator; their lifespan should be better than on earth due to factors like microgravity (little to no bearing wear), no dust to ingest, etc. Radiators can be placed directly behind the mirrors to cool the fluid for completion of a cycle if needed.

A signal from the ground is used to control the phased array sending from the satellite. If the beam drifts off the receiver, the signal stops, and the phase goes incoherent: no beam until the problem is corrected.

The "down side" of going up top is initial cost, and methods were worked out for that decades ago, basically beginning with an electromagnetic rail gun-like device on the western slopes of the rocky mountains to launch payloads up to orbit; they don't need oxygen or warmth or food, nor are they sensitive to 10 or 15 time "g".

Why be pedestrian about solar power?

For me spending all of that money to get a higher rate of return on a solar array that is going to get busted and need repair, and the trip costs really are mind boggling are the closure points I see.

Just imagine how many miles & acres & sheer number of customers who can be taken care of down here utilizing the Arizona and New Mexico National Forrest areas. I mean cactus rock and lizards and buzzards are all you find for millions of square miles.

The real-estate will be cheap at least and getting some highly experienced solar power repairman out there in his pickup truck is going to cost just what fraction of one single percent of the repair trip up there in Orbit???

I Dun know how you are calculating the ROI but to me the Consumer / Tax Payer that I am, the pickup truck is what I wanna pay for. Why don't you pay for that space trip.

This is right direction we are heading on , if we want this technology to sustain ( this is the future??) , battery technology is major herdal to make this acceptable , just like oil outlets are supported by oil industry , but why would someone buy electricity from these outlets when they have in there home unless emergency , need . we do not have alternative fuel at our disposable at our home for our regular vehicles , and also supply of necessary quantity through other means like bio fuels from farms .

Do we have a electric fuel in liquid format ( charged electrolyte) that will be replaced with discharged electrolyte for further charging with special batteries meant for automobiles only , or replace batteries wholly from car just like gas cylinder for quick refill .or new kind of electricity that we people are not much aware of as , is it different from AC or DC that will be only provided by theses proposed outlets , because you guys are comparing with telephony
