Meni inače nikad nije bilo jasno zašto ne postoje vlakovi na skijama koji se kližu po ledu. Potrebna je relativno mala količina leda a otpor kotrljanja, tj. sila trenja, vrlo mala. Danas postoji i umjetni led koji je otporan na temperature iznad 0.

Pa ta njegova Tesla je trenutačno jedan od najvećih balona na burzi, imaju veći market cap od FiatChryslera, koji prodaje oko 4 milijuna automobila godišnje, vlasnici su luksuznih brendova Maserati i Ferrari, koji oba imaju veće prihode od Tesle te za razliku od Muskove igračke posluju s dobiti, također Chryslerovi brendovi imaju veliki rast na tržištu SAD-a, posebice Jeep. S druge strane, Tesla motors stalno daje neke projekcije broja prodanih automobila i priča o električnim vozilima kao budućnosti, no pitanje je koliko je to realno s obzirom na pad cijena nafte koji je rezultirao ponovnim rastom SUV segmenta te su nakon dugo godina prve tri pozicije otišle Pick-upovima. A isto tako, i tradicionalni igrači se sve više uključuju na tržište EV, a oni za razliku od Tesle mogu izdržati novi naftaški val.

The posted market cap for GM is $57.71 billion, based on Tuesday’s share price, and the stock trade at 15.19 times earnings. Investors also get the added luxury of a very respectable 3.3% dividend. The market cap for Tesla sits today at $30.54 billion, and the stock trades an incredible 1200 times earnings, using very fast and loose accounting rules. The company actually lost $74 million dollars last year. The short sellers are circling the stock. Doug Kass, who runs Seabreeze Partners Management, is a skeptic and has sold the stock short. He also thinks the Tesla/Apple chatter is pure hype.

Kako Rimcu ide trenutno ?

Manufakturno. Ne znam je li prodao više od tri auta do sada. Ako bude ko onaj švedski koenigsegg bit će super, znači prodaja od dvadesetak automobila godišnje.

Baš si biser inovatorski. Kako bi kočio, kukovima u stranu.

Nisu oni nikakvi pioniri, već sada su na tržištu Nissan(najprodavaniji potpuno električni automobil u SAD-u je njihov Leaf), Toyota i BMW, a kroz dvije tri godine će tu biti svi. A upravo će te sljedeće dvije-tri godine biti u znaku niske cijene nafte i slabijeg razvoja tržišta električnih automobila, tako da se Tesla neće stići nametnuti.

Ne možeš kočiti ako ga ne digneš od leda. Onda ti led i ne treba.

Tesla motors je u 27 postotnom vlasništvu Toyote i trenutno sudjeluju na razvoju eSUV platforme te da ih smatraju opasnima bi već iskeširali za ostatak.

Da bi imao led moraš ispod njega imati el. vodove, koji pak stvaraju em polje, dakle dovoljno je u polje spustit magnet suprotnog potencijala i kočiš. Uostalom, između skija koje idu po ledu, možeš imat nešto (tračnicu npr.) koja bi služila za kočenje kad treba i sl. Možeš i padobran pustit čak. Ima 100 varijanti.

De prestani. Ti bi putovao samo dva mjeseca zimeö

Tesla CEO Elon Musk Unveils Line of Home and Industrial Battery Packs



‘We’re talking about trying to change the fundamental energy infrastructure of the world,’ Musk says

HAWTHORNE, Calif.—Tesla Motors Inc. Chief Executive Elon Musk unveiled a line of home and industrial battery packs late Thursday, representing a strategic shift as his money-losing electric car company tries to break into a crowded energy storage market.

More than just a splashy evening party in a giant hangar at Tesla’s Southern California design studios, the event was the 43-year-old billionaire’s attempt to bring attention to an alternative business unit that has long been under development.

Mr. Musk says “power wall” batteries—ranging from a $3,000 7 kilowatt-hour wall-mounted unit to a $3,500 10 kwh unit—cost far less than the going rate for large-scale batteries and can be easier to install. Tesla aims to begin delivering units by the summer from its car factory in California, and then shift production to a $5 billion “gigafactory” battery plant under construction near Reno, Nev.

Tesla will also sell massive battery blocks for industrial users and open-source the patents for the entire range, much like the company does with electric-car technology. Mr. Musk portrayed the effort as a breakthrough toward transforming energy use in favor of renewable resources.

“We’re talking about trying to change the fundamental energy infrastructure of the world,” he said during a public unveiling. “This is actually within the power of humanity to do. It is not impossible.”

Mr. Musk sees the potential for the battery business to match or surpass Tesla’s car business in terms of the potential for energy generation. He expects demand to range from countries where solar is popular, such as Germany, to developing economies that don’t have existing power lines.

Eventually, he expects Tesla will need to build more factories modeled after its Nevada gigafactory.

Tesla’s first battery customers include Green Mountain Power Corp., Vermont’s largest utility. It plans to buy Tesla packs and sell them to customers that already have solar power.

Green Mountain Power Chief Executive Mary Powell said she thinks the rapid spread of solar power, combined with lower battery costs, will lead a revolution in power distribution.

Another customer is TreeHouse, an Austin-based home improvement store concentrating on ecologically friendly goods. The store will sell the battery packs along with its own solar installation options.

A new market is growing for robust batteries. Initially developed for electric cars, they are now being installed at buildings, wind farms and other places that can store electricity for later use.

About 62 megawatts of batteries and other energy-storage devices were installed in 2014 at 180 properties, at a value of about $128 million, up 40% from the previous year, according to energy research firm GTM Research. Battery installations this year are likely to more than triple, to 220 megawatts, the firm predicts.

Utilities such as Duke Energy Corp. and Edison International have installed large battery systems next to wind farms. The batteries store electricity that the wind turbines generate at night and release the power to the grid in the late afternoon and early evening when electricity demand spikes.

Other companies, such as Stem Inc. and Green Charge Networks are installing batteries for large retailers and hotels, to help the companies limit their power usage and cut their utility bills.

Government subsidies can reduce the cost of installing the batteries. In California, state rebates cover up to 60% of the price of the battery. Nationwide, batteries that are connected to solar panels are eligible for federal tax credits equal to 30% of the price of the battery.

California’s subsidies and a mandate requiring utilities to use batteries or other devices to store power have put that state at the center of the stationary energy-storage market. Hawaii, Texas and some eastern states also are using batteries to store electricity from solar panels and wind farms, and to keep the flow of electricity on transmission lines moving smoothly.

Tesla batteries will initially use cells made by Panasonic Corp., the supplier of batteries in its Model S electric sedan. When production shifts to Reno, costs will drop by 30%.

The new battery models include large, standing industrial-level batteries intended for use by utilities sold in units of 100 kilowatt-hours, which cost $250 per kilowatt-hour. The company already has a customer with plans to install 250 megawatt-hours-worth of such batteries, Mr. Musk said.

Its home model, called “power wall,” comes in sleek black and white models and will be aimed at people who want to more efficiently use power from solar panels or go entirely off the electrical grid, Mr. Musk said.

The Power Wall batteries will be installed through certified third parties, including SolarCity Corp., where Mr. Musk is chairman.
