A $100 Dollar per kWh battery for Tesla Semi? Could be.

Elon Musk is 'optimistic' about beating Tesla Semi specs that competitors already don't believe possible

As we reported last week and discussed on the Electrek podcast yesterday, many people still have a difficult time wrapping their head around the Tesla Semi specs that the company announced last year. But now CEO Elon Musk says that he is 'optimistic' they can beat those specs with the production version of the electric truck.



From article, (Elon Musk
Musk didn’t specify which specs in particular, but the article mainly involves the economics of operating a Tesla Semi, which is the most important thing for fleet operators.
Here are the main specs that Tesla revealed at the unveiling event:
  • Acceleration from 0 to 60 mph with 80,000 lb: 20 seconds
  • Speed up a 5% Grade:60 mph
  • Mile Range: 300 or 500 miles
  • Powertrain: 4 Independent Motors on Rear Axles
  • Energy Consumption: Less than 2 kWh per mile
  • Fuel Savings: $200,000+
  • Expected Base Price (300 mile range): $150,000
  • Expected Base Price(500 mile range): $180,000
Tesla estimates a payback period of about 2 years thanks to gas and maintenance savings.

Musk is talking about beating those specs, which would be even more impressive.
My greatest concern is cost. Tesla doesn’t confirm its current battery cost, but it is estimated to be somewhere around $150 at the pack level.

The same cost for a 1 MWh battery pack, which would be required for Tesla to achieve a 500-mile range, would be $150,000.

There are likely going to be some cost improvements at the pack level due to the greater size, but it looks like a cost breakthrough (something closer to the mythical $100 per kWh battery holy grail) is almost needed for Tesla to make it work.)


The Moon has LOTS of water. It makes the prospects for a Moonbase better (Since you can supply Water and Oxygen to Astronauts) and The Moon can be used as a fuel depot (Water Broken up into Hydrogen and Oxygen) for spacecrafts and probes.

New Research Suggests the Moon Has Widespread Water

Now that there's talk of going back to the Moon at some point, perhaps to even set up a more longterm colony, this raises the question of how to make a lunar colony sustainable.
From article, (new research used data from both NASA’s Lunar Reconnaissance Orbiterand their Moon Mineralogy Mapper spectrometer, which helped them create a means of measuring reflected sunlight that could see through the Moon's glowing. And they suddenly found there was more water than they'd anticipated.

According to Joshua Bandfield, lead author on the study and senior research scientist with the Space Science Institute in Boulder, Colorado, who said the following in a press release from NASA:
Opening quote
"We find that it doesn’t matter what time of day or which latitude we look at, the signal indicating water always seems to be present. The presence of water doesn’t appear to depend on the composition of the surface, and the water sticks around."
 There are still a lot of questions that need to be solved before we just send off a new team of astronauts and tell them to drink whatever they find on the lunar surface. The nature of the water is still unclear (knowing whether we're picking up signs of water or hydroxyl is an important distinction) and how easily accessible it is. Just because it's everywhere doesn't mean it isn't tough to extract, and the research suggests that water wouldn't be loosely attached to the surface.

But it's a start. Eventually we might be able to send off astronauts and tell them to drink whatever they find on the lunar surface. Just not yet.)

Streamlining Regulations was the Goal at the Recent National Space Council

National Space Council acts to streamline regulatory hurdles

STORY WRITTEN FOR CBS NEWS & USED WITH PERMISSION The newly re-activated National Space Council is acting quickly to streamline convoluted regulatory requirements that frequently slow development of new commercial space initiatives, a shift in focus in keeping with the Trump Administration's directive to encourage more private sector development on the high frontier.
From article, (Chaired by Vice President Mike Pence, the space council met at the Kennedy Space Center Wednesday to review recommendations that will be sent to the president for approval, re-iterating the administration’s push to end government funding of the International Space Station in 2025 in favor of one or more commercially-developed follow-on outposts.
“President Trump and our entire administration believe that America’s prosperity, security and even our national character depend on American leadership in space,” Pence said in a cavernous room where space station components were once assembled and tested before launch.
But U.S. companies “are often stifled by a convoluted maze of bureaucratic obstacles and outdated regulatory processes,” he said. “Today’s launch licensing regime is plagued by burdensome government barriers.”
Government launch licenses, for example, “can’t be transferred from one site to another,” Pence said. “So if a company receives its license to launch a rocket from the Kennedy Space Center but then wants to move their mission to California or even just a few miles away from Cape Canaveral, that same company must complete the entire process all over again.”
“The government’s figured out how to honor drivers licenses across state lines, there’s no reason we can’t do the same for rockets.”
During Wednesday’s pubic session, Jeffrey Rosen, Deputy Secretary of Transportation, outlined a 45-day plan to overhaul, modernize and streamline the space licensing framework to speed up FAA reviews, expand the use of waivers to gain quick “interim relief” and to set up a joint task force to ensure better cross-agency cooperation.
The new licensing framework is aimed at enabling a much more rapid “file-and-fly” application-to-approval process.
Secretary of Commerce Wilbur Ross said the space business is a $330 billion industry supporting 211,000 jobs.
“But our share of the 1,700 new companies created worldwide last year was only 45 percent, far lower than our share of launches,” he said. “Private companies funded $3.9 billion of our space effort last year, but they’re competing against 70 foreign governments. So they need all the support we can give them.”
 “Satellite companies now face a permitting timeline that can take five years … and provides no certainty or predictability to industry,” he added. “This is unacceptable and must change. Otherwise, companies and customers will go overseas.”
Ross said the Commerce Department is working to create a “new, one-stop shop for space commerce.” Several offices across multiple agencies that deal with different aspects of the space industry will be consolidated in a single Commerce Department office “to coordinate all space-related functions.”
Pence outlined four recommendations based on the council’s work since the first meeting last October that will be sent to the president for approval.
First, the Department of Transportation will be directed to replace restrictive launch and re-entry licensing regimes with a more streamlined system by March 1, 2019. As outlined by Ross, the Commerce Department will move all space commerce responsibilities into a single office monitored directly by the secretary to facilitate mission authorization for commercial space initiatives.
Space-related export control requirements also will be streamlined, with a new framework in place by Jan. 1, 2019. And the National Telecommunications Information Administration will work to develop guidelines for protecting the radio frequency spectrum used by satellite systems to encourage expanded commercial space activities.
“These recommendations, I believe, will transform the licensing regimes that oversee launch, re-entry and new commercial space operations, and they’ll empower American businesses to create the jobs of the future, attract new investment to our shores and unlock new opportunities, new technologies and new sources of American prosperity,” Pence said.)
