These former Tesla employees defected to a new, top-secret rival

Posted by in categories: space travel, sustainability

Tesla new competitor is in town, they are paying top dollar for Tesla’s talent. Guess Musk should have backed off SpaceX, because his money making has serious competition.


Tesla has lost a lot of talent to this company.

Can we Afford to go Into Space?

Posted by in categories: business, economics, materials, military, solar power, space, sustainability

Space is not a government program; it’s the rest of the Universe. Private space business is now a major factor, bent on finding investors interested in generating profits by making space more accessible to more people. Space business pays taxes to governments; it does not consume tax revenues. Further, space business can offer launch services to government agencies at highly competitive rates, thus saving taxpayer dollars. How can they do this, competing with government-funded boosters with a 50-year track record? Simple: governments have no incentive to cut costs. Traditional aerospace industry giants have a huge vested interest in boosters that were developed to military and NASA standards, among which economy was not even an issue. But innovative, competitive companies such as XCOR Aerospace and Mojave Aerospace, without such baggage (and overhead) can drive costs down dramatically. This is a proven principle: notice that we are no longer buying IBM PCs with 64 k of RAM for $5000 a unit.

Even more important in the long view, space is a literally astronomical reservoir of material and energy resources. The profit potential of even a single such resource, such as solar power collectors in space beaming microwave power to Earth, is in the trillions of dollars. What would it be worth to the world to reduce fossil fuel consumption by a factor of 20 or 100 while lowering energy costs? Can we afford to continue pretending that Earth is a closed system, doomed to eke out finite resources into a cold, dark future?

Can we afford space? Wrong question. Can businesses afford space? Yes. We get to reap the benefits of their innovative ideas and free competition without footing the bill.

Self-cleaning, anti-glare windows inspired by moth eyes

Posted by in categories: engineering, materials, sustainability

A new type of glass to reducing electric bills.


A revolutionary new type of smart window developed by the University College London (UCL) and the Engineering and Physical Sciences Research Council (EPSRC) could cut window-cleaning costs in tall buildings while reducing heating bills and boosting worker productivity. Partially inspired by the reflective properties of moth eyes, this smart window is said to be self-cleaning, energy saving, and anti-glare.

When rain hits the outside of the smart window it forms spherical droplets that roll over the surface and pick up dirt, dust and other contaminants, then carries them away. This can either eliminate or reduce the need for manual cleaning.

A Brief History of Stephen Hawking Being a Bummer

Posted by in categories: engineering, existential risks, genetics, sustainability

Yeah, he’s turned into quite the man-of-panic as of late.


Stephen Hawking is at it again, saying it’s a “near certainty” that a self-inflicted disaster will befall humanity within the next thousand years or so. It’s not the first time the world’s most famous physicist has raised the alarm on the apocalypse, and he’s starting to become a real downer. Here are some of the other times Hawking has said the end is nigh—and why he needs to start changing his message.

Speaking to the Radio Times recently ahead of his BBC Reith Lecture, Hawking said that ongoing developments in science and technology are poised to create “new ways things can go wrong.” The scientist pointed to nuclear war, global warming, and genetically-engineering viruses as some of the most serious culprits.

New battery made of molten metals may offer low-cost, long-lasting storage for the grid

Posted by in categories: climatology, materials, sustainability

A novel rechargeable battery developed at MIT could one day play a critical role in the massive expansion of solar generation needed to mitigate climate change by midcentury. Designed to store energy on the electric grid, the high-capacity battery consists of molten metals that naturally separate to form two electrodes in layers on either side of the molten salt electrolyte between them. Tests with cells made of low-cost, Earth-abundant materials confirm that the liquid battery operates efficiently without losing significant capacity or mechanically degrading—common problems in today’s batteries with solid electrodes. The MIT researchers have already demonstrated a simple, low-cost process for manufacturing prototypes of their battery, and future plans call for field tests on small-scale power grids that include intermittent generating sources such as solar and wind.
