SpaceX ramps South Texas activity to prepare for 2019 BFR spaceship testing

Published

on

At the same time as the hardware for SpaceX’s first BFR spaceship is entering the early stages of manufacturing, the company’s South Texas test facility is slowly taking shape after more than 18 months of what can be fairly described as hibernation.

The likeliest location for a near-future spaceship test stand or pad has also experienced a comparatively vast influx of construction workers and general activity that began earlier this month September, nearly two and half years after SpaceX began preparing the unstable coastal wetland with the addition of several hundred tons of soil.

It may not look like much, but ~5 contractors and a few pieces of heavy machinery truly is an explosion of SpaceX activity in South Texas. The hill in the background is the soil surcharging mound. (Maria Pointer, 09/19/2018)

According to a number of posts from local Texans that are also members of a small SpaceX fan group on Facebook, activity around the company’s Boca Chica, Texas facilities has exploded in recent months, and even more so over the last several weeks. SpaceX’s ground tracking facility has harbored the vast majority of attention for some time, particularly following the relatively recent arrival of a massive crane, construction of a shelter for said crane, and the appearance of two massive vacuum-insulated tanks for liquid oxygen (LOX) and liquid methane/natural gas (LNG).

Presently sat beside two large antennae on the Crew Dragon tracking facility’s plot, those propellant tanks are certainly both eye-catching and definitive evidence that something huge and nearby will soon need large quantities of liquid propellant. In the case of the LOX tank, a back-the-envelope estimate suggests that it can hold an obscene 400 metric tons (~900,000 lbs) of liquid oxygen, while the much smaller LNG tank (assumed, not guaranteed) would be capable of holding less than 25,000 kg of liquid methane, thanks mainly to the fact that liquid methane is roughly three times less dense than LOX.

Thankfully, SpaceX’s BFR Raptor engines will nominally burn oxygen and methane at a ratio of approximately 3.8 to 1, meaning that every 1 kg of methane exiting the rocket will be accompanied by 3.8 kg of oxygen. The fact that this ratio is actually larger than the density ratio of LOX and LNG means that the propellant tanks can be almost the same size

Most notably, as described above, is the abrupt return of construction and site preparation activities at what once was expected to be a Falcon 9 and Heavy launch pad. Over the last 24+ months, SpaceX has simply let the lot sit, although in this case, that sitting was rather productive. Known as soil surcharging, the site was essentially leveled, loaded with hundreds of tons of soil, plumbed with drainage pipes, and then left alone up to this point to let gravity do the rest of the work. Put simply, the unsteady soil of coastal Texas was aggressively drained and compacted into something stable enough to build expensive, long-term facilities on.

The hundreds of truckloads it took to bring in the soil will have to be repeated in reverse, removing most of the same soil to leave a level field ready for foundation-laying and series construction. Heavy machinery and construction contractors began arriving earlier this month, indicating that that process is about to begin, after which construction of the facilities that will eventually support Grasshopper-style spaceship testing can begin in earnest. Those BFR hop tests are scheduled to begin no earlier than late 2019.

Tesla launches Powerwall Lease for affordable home backup

Published

on

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.

Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.

The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla announces 100k Powerwalls are participating in Virtual Power Plants

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.

Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.

The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.

Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again

Published

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor

Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.

Published

By

Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”

The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.

SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
