The fact that Nextbigfuture has been right on Tesla for years is less important than the fact that Tesla has several more years of crazy share price growth. The years of being correct is public evidence that Nextbigfuture has credibility as a Tesla bull. In Jan, 2019, I wrote about Tesla buying Maxwell dry cell…
Nanogaps between plasmonic electrodes produced 10,000 times more light than expected. Hot electrons were created by electrons driven to tunnel between gold electrodes, their recombination with holes emitted bright light, and the greater the input voltage, the brighter the light. This could be useful for applications in optoelectronics, quantum optics and photocatalysis. The effect depends…
If we send telescopes out to 4 light days we can use the gravity of the sun to amplify the power of telescopes by 100 billion times. Although we can build larger telescopes with higher resolution than exists today near to Earth, the telescopes that are sent out to gravitational lensing regions would resolve much…
The US has runway repair teams that can repair holes in two hours or less. They use truckloads of dirt and rocks and then cover with a 45 by 60-foot fiberglass mat. Chinese suppliers sell fiberglass paving mats for 55 cents per square meter in lots of 10000 square meters. T17 fast setting cement can…
A large reservoir of freshwater was discovered beneath Fiery Cross Reef, one of the artificial islands China made in the South China Sea. The reservoir is growing at a rate of about 1 meter (3.3 feet) per year. This is twice as fast as reservoir water level growth in naturally formed islands. Freshwater can support…
There is a company called Nikola which claims they will sell semi-trucks using hydrogen. Amazingly, with virtually no revenue and no vehicles made, Nikola is worth over $22 billion. They say they will lease the vehicles and get hydrogen for $2 per kilogram. Most have the lowest cost of hydrogen at about $2.5-4.5 per kilogram.…
People know that computers became a multi-trillion dollar industry because it rode the exponential growth in power of Moore’s Law. Aviation also experienced decades of exponential growth and Space has had ten years of exponential growth and is looking at 40 years of exponential growth. Air passenger travel had decades of exponential growth in passengers.…
A new six-junction solar cell, developed by NREL (National Renewable Energy Laboratory), converts 47.1% of incident light into electricity when combined with optical concentration. Indications thus far suggest solar cells of this type can reach an efficiency rate of 50%. There are a number of obstacles to commercialization, though NREL believes that will probably be…
RUSI provides an analysis of China and India military balance and the border war situation. Royal United Service Institute (RUSI) is the world’s oldest and the UK’s leading defense and security think tank. Its mission is to inform, influence and enhance public debate on a safer and more stable world. RUSI is a research-led institute,…
Researchers have found that age-reversing effects can be achieved by simply diluting the blood plasma of old mice — no young blood needed. Above – Older mice grew significantly more new muscle fibers, shown as pink “donut” shapes, after undergoing a procedure that effectively diluted the proteins in their blood plasma (bottom) than they did…
Exotic states called Kohn anomalies been found for the first time in an unexpected type of material and this could lead to new quantum devices. The researchers induced a Kohn anomaly, which was previously thought to exist only in metals, in an exotic material called a topological Weyl semimetal. The finding could help shed light…
Amazon announced The Climate Pledge Fund to support the development of sustainable technologies and services that will enable Amazon and other companies to meet The Climate Pledge—a commitment to be net zero carbon by 2040. This dedicated venture investment program—with an initial $2 billion in funding—will back visionary companies whose products and services will facilitate…
